139-603: Most notably, it is the site of the discovery of anatomically modern human remains , apparently buried at the site, dated to about 28,000 years ago. Because of its archeological importance, Abri de Cro-Magnon was inscribed on the UNESCO World Heritage List as part of the Prehistoric Sites and Decorated Caves of the Vézère Valley site. In 1868, workmen found animal bones, flint tools, and human skulls in

278-583: A creationist model (as the concept of evolution had not yet been conceived). For example, the Aurignacian Red Lady of Paviland (actually a young man) from South Wales was described by geologist Reverend William Buckland in 1822 as a citizen of Roman Britain . Subsequent authors contended the skeleton was either evidence of antediluvian (before the Great Flood ) people in Britain, or was swept far from

417-498: A founder mutation is a mutation that appears in the DNA of one or more individuals which are founders of a distinct population. Founder mutations initiate with changes that occur in the DNA and can be passed down to other generations. Any organism—from a simple virus to something complex like a mammal—whose progeny carry its mutation has the potential to express the founder effect, for instance

556-601: A "Basal Eurasian" component to the genome, nor did they find evidence of Mal'ta–Buret' introgression when looking at a wider range of Cro-Magnons from the entire Upper Palaeolithic. The study instead concluded that such a genetic makeup in present-day Europeans stemmed from Near Eastern and Siberian introgression occurring predominantly in the Neolithic and the Bronze Age (though beginning by 14,000 years ago), but all Cro-Magnons specimens including and following Kostenki-14 contributed to

695-645: A catalog of disease-associated variation in these populations enables rapid, early, and accurate diagnoses that may improve patient outcomes due to informed clinical management and early interventions. Enclosed communities such as Amish communities, Ashkenazi communities, and relatively isolated islands allow scientists to better understand and further discover the mutated genes that cause these rare diseases and allow them to also discover protective genes as well. Due to various migrations throughout human history, founder effects are somewhat common among humans in different times and places. The French Canadians of Quebec are

The beginning of the Upper Palaeolithic is thought to have been characterised by a major population increase in Europe, with the human population of western Europe possibly increasing by a factor of 10 in the Neanderthal/modern human transition. The archaeological record indicates that

973-493: A classical example of founder population. Over 150 years of French colonization, between 1608 and 1760, an estimated 8,500 pioneers married and left at least one descendant on the territory. Following the takeover of the colony by the British crown in 1760, immigration from France effectively stopped, but descendants of French settlers continued to grow in number mainly due to their high fertility rate. Intermarriage occurred mostly with

They seem to have scheduled mass kills to coincide with migration patterns, in particular for red deer, horses, reindeer, bison , aurochs , and ibex, and occasionally woolly mammoths . Game drive systems became especially popular following the LGM, possibly an extension of increasing food return. There are also multiple examples of consumption of seasonally abundant fish, becoming more prevalent in

1251-653: A community which practices both endogamy and polygyny , where an estimated 75–80% of the community are blood relatives of just two men—founders John Y. Barlow and Joseph Smith Jessop . In South Asia, castes like the Gujjars , the Baniyas and the Pattapu Kapu have estimated founder effects about 10 times as strong as those of Finns and Ashkenazi Jews . In Africa, many members of the Vadoma tribe inherit ectrodactyly , giving them

1390-555: A genetic condition called Neurofibromatosis type I , which would have led him to have large cysts or tumours on his face, evident in the depression in the frontal bone and pits of the eyebrows and cheek bones . Compared to Neanderthals, the skeletons showed the same high forehead, upright posture and slender ( gracile ) skeleton as modern humans. The other specimens from the site are a female, Cro-Magnon 2, and male remains, Cro-Magnon 3. European early modern humans Cro-Magnons or European early modern humans ( EEMH ) were

1529-416: A goat or a human. Founder mutations originate in long stretches of DNA on a single chromosome ; indeed, the original haplotype is the whole chromosome. As the generations progress, the proportion of the haplotype that is common to all carriers of the mutation is shortened (due to genetic recombination ). This shortening allows scientists to roughly estimate the age of the mutation. The founder effect

1668-475: A group before the LGM and thus were more likely to be buried and preserved. Prior to genetic analysis, it was generally assumed that Cro-Magnons, like present-day Europeans, were light skinned as an adaptation to better generate vitamin D from the less luminous sun farther north. However, of the three predominant genes responsible for lighter skin in present-day Europeans – KITLG , SLC24A5 , and SLC45A2  – the latter two, as well as

1807-563: A group of small islands in the Atlantic Ocean, midway between Africa and South America. One of the early colonists apparently carried a rare, recessive allele for retinitis pigmentosa , a progressive form of blindness that afflicts homozygous individuals. As late as 1961, the majority of the genes in the gene pool on Tristan were still derived from 15 original ancestors; as a consequence of the inbreeding, of 232 people tested in 1961, four were suffering from retinitis pigmentosa. This represents

1946-524: A hamlet in the commune of Les Eyzies-de-Tayac-Sireuil , Dordogne, southwestern France. In 1868, M. François Berthoumeyrou, a contractor, was commissioned to make a road along the railway connecting the new Les Eyzies train station. In March, the road workers dug up a rock shelter , around 10 m (33 ft) deep, on the left bank of the Vézère River . They found flint stone tools , animal bones, and human remains. Berthoumeyrou ordered his men to halt

2085-489: A higher proportion of traits somewhat reminiscent of Neanderthals, such as (though not limited to) a slightly flattened skullcap and consequent occipital bun protruding from the back of the skull (the latter could be quite defined). Their frequency significantly diminished in Gravettians, and in 2007, palaeoanthropologist Erik Trinkaus concluded these were remnants of Neanderthal introgression which were eventually bred out of

2224-487: A hypothetically tall ancestral condition; higher-quality diet and nutrition due to the hunting of megafauna which later became uncommon or extinct; functional adaptation to increase stride length and movement efficiency while running during a hunt; increasing territorialism among later Cro-Magnons reducing gene flow between communities and increasing inbreeding rate; or statistical bias due to small sample size or because taller people were more likely to achieve higher status in

2363-463: A low success rate. The concept of "Woman the Gatherer" has since gained significant support. Nonetheless, Palaeolithic peoples are typically characterised as having had a meat-heavy diet, with an emphasis on big prey items. The LGM extirpated most European megafauna ( Quaternary extinction event ), and similarly post-LGM peoples tend to have a higher rate of nutrient-deficiency-related ailments, including

2502-605: A random change in genetic frequency of population favours the survival of a few organisms of the species with rare genes which cause reproductive mutation. These surviving organisms then breed among themselves over a long period of time to create a whole new species whose reproductive systems or behaviors are no longer compatible with the original population. Serial founder effects have occurred when populations migrate over long distances. Such long-distance migrations typically involve relatively rapid movements followed by periods of settlement. The populations in each migration carry only

2641-492: A rather complex, cross-continental social organisation system. By and following the LGM, population densities are thought to have been much higher with the marked decrease of habitable lands, resulting in more regional economies. Decreased land availability could have increased travel distance, as habitable refugia may have been few and far between, and increasing population density within these few refugia would have made long-distance travel less economic. This trend continued into

2780-520: A recessive disease may increase in just few generations). The genetic abnormality will increase incrementally with the decrease of number of isolated populations making tribe-specific diseases (such as Ashkenazis , Amish, and Bedouins ) and novel genetic defects. In recessive diseases, founder populations where underlying levels of genome-wide homozygosity are high due to shared common ancestry, but also for consanguineous populations that will have large genome-wide homozygous regions due to inbreeding. Having

2919-652: A reduction in average height. Probably due to the contraction of habitable territory, these bands were subsisting on a much broader food range of plants, smaller animals, and aquatic resources ( broad spectrum revolution ). It has typically been assumed that Cro-Magnons closely studied prey habits in order to maximise return depending on the season. For example, large mammals (including red deer , horses, and ibex ) congregate seasonally, and reindeer were possibly seasonally plagued by insects rendering fur sometimes unsuitable for hideworking. In particularly southwestern France, Cro-Magnons depended heavily upon reindeer, and so it

3058-569: A second wave succeeded in forming a single founder population, from which all subsequent Cro-Magnons descended and which contributes ancestry to present-day Europeans. Cro-Magnons produced Upper Palaeolithic cultures, the first major one being the Aurignacian , which was succeeded by the Gravettian by 30,000 years ago. The Gravettian split into the Epi-Gravettian in the east and Solutrean in

3197-536: A series of skulls from Brno , Czech Republic, purportedly transitional between Neanderthals and Cro-Magnons; H. mentonensis for a skull from Menton , France; " H. grimaldensis " for Grimaldi man and other skeletons near Grimaldi, Monaco; and " H. aurignacensis " or " H. a. hauseri " for the Combe-Capelle skull. These fossil races, alongside Ernst Haeckel 's idea of there being backwards races which require further evolution ( social darwinism ), popularised

3336-456: A severe bottleneck. They inhabit the Tyrrhenian islands and surrounding mainlands currently, and before the bottleneck, but Hajji and others wanted to know how the deer originally got to the islands, and from what parent population or species they were derived. Through molecular analysis, they were able to determine a possible lineage, with red deer from the islands of Corsica and Sardinia being

3475-533: A shaft to be used as javelins . It is possible that Aurignacian craftsmen further hafted bone barbs onto the spearheads, but firm evidence of such technology is recorded earliest 23,500 years ago, and does not become more common until the Mesolithic. Aurignacian craftsmen produced lozenge -shaped (diamond-like) spearheads. By 30,000 years ago, spearheads were manufactured with a more rounded-off base, and by 28,000 years ago spindle-shaped heads were introduced. During

3614-465: A significant temperature drop. Also around 37,000 years ago, the founder population of all later early modern humans existed, and Europe would remain in genetic isolation from the rest of the world for the next 23,000 years. Around 29,000 years ago, marine isotope stage 2 began and cooling intensified. This peaked about 21,000 years ago during the Last Glacial Maximum (LGM) when Scandinavia ,

3753-460: A subset of the genetic diversity carried from previous migrations. As a result, genetic differentiation tends to increase with geographic distance as described by the "isolation by distance" model. The migration of humans out of Africa is characterized by serial founder effects. Africa has the highest degree of human genetic diversity of any continent, which is consistent with an African origin of modern humans. Founder populations are essential to

3892-511: A substantial contribution to the genomes of later Europeans. Therefore, it is possible that interbreeding was common between Neanderthals and Cro-Magnons which did not contribute to the present-day genome. The percentage of Neanderthal genes gradually decreased with time, which could indicate they were maladaptive and were selected out of the gene pool. Valini et al. 2022 found that Europe was populated by three distinct lineages. The earliest inhabitants (represented by Zlaty Kun ~50kya) split from

4031-617: A third are depicted with erections.) On the other hand, most individuals which received a burial (which may have been related to social status) were men. Anatomically, the robustness of limbs (which is an indicator of strength) between Cro-Magnon men and women were consistently not appreciably different from each other. Such low levels of sexual dimorphism through the Upper Pleistocene could potentially mean that sexual division of labour , which characterises historic societies (both agricultural and hunter-gatherer), only became commonplace in

4170-926: A time. The Cro-Magnon arsenal included spears, spear-throwers , harpoons , and possibly throwing sticks and Palaeolithic dogs . Cro-Magnons likely commonly constructed temporary huts while moving around, and Gravettian peoples notably made large huts on the East European Plain out of mammoth bones. Cro-Magnons are well renowned for creating a diverse array of artistic works, including cave paintings , Venus figurines , perforated batons , animal figurines, and geometric patterns. They also wore decorative beads, and plant-fibre clothes dyed with various plant-based dyes. For music, they produced bone flutes and whistles, and possibly also bullroarers , rasps , drums, idiophones , and other instruments. They buried their dead, though possibly only people who had achieved or were born into high status. The name "Cro-Magnon" comes from

4309-420: Is a partially preserved female skull with marked facial similarities to Mladeč 2 . Cro-Magnon 3 is a partial skull of a male adult. The remains are thought to represent adults who died at an advanced age, who were placed at the site, along with pieces of shell and animal teeth in what appear to have been pendants or necklaces, in an apparent intentional burial . The presence of necklaces and tools suggests

4448-623: Is a series of modern human teeth with Neronian industry stone tools found at Mandrin Cave , Malataverne in France, dated in 2022 to between 56,800 and 51,700 years ago. The Neronian is one of the many industries associated with modern humans classed as transitional between the Middle and Upper Palaeolithic. Beyond this there is the Balkan Bohunician industry beginning 48,000 years ago, likely deriving from

4587-692: Is a type of genetic drift , occurring when a small group in a population splinters off from the original population and forms a new one. The new colony may have less genetic variation than the original population, and through the random sampling of alleles during reproduction of subsequent generations, continue rapidly towards fixation . The homozygosity increase can be calculated as Δ f = 1 / 2 N {\displaystyle \Delta {f}=1/2N} , where f {\displaystyle f} equals inbreeding coefficient and N {\displaystyle N} equals population size. This consequence of inbreeding makes

4726-631: Is also unclear where the Gravettian originated from as it diverges strongly from the Aurignacian (and therefore may not have descended from it). Nonetheless, genetic evidence indicates that not all Aurignacian bloodlines went extinct. Hypotheses for Gravettian genesis include evolution: in central Europe from the Szeletian (which developed from the Bohunician) which existed 41,000 to 37,000 years ago; or from

4865-418: Is debated if this represents sample bias , and if western and northern Europe were less mobile. Some cultural practices such as creating Venus figurines or specific burial rituals during the Gravettian stretched 2,000 km (1,200 mi) across the continent. Genetic evidence suggests that, despite strong evidence of cultural transmission, Gravettian Europeans did not introgress into Siberians, meaning there

5004-456: Is difficult to tell if all material from a site was deposited at about the same time, or if the site was used multiple times. Cro-Magnons are thought to have been quite mobile, indicated by the great lengths of trade routes, and such a lifestyle was likely supported by the constructions of temporary shelters in open environments, such as huts. Evidence of huts is typically associated with a hearth. Founder effect In population genetics ,

5143-535: Is hypothesised that these communities followed the herds, with occupation of the Perigord and the Pyrenees only occurring in the summer. Epi-Gravettian communities, especially, generally focused on hunting one species of large game, most commonly horse or bison. There is much evidence that Cro-Magnons, especially in western Europe following the LGM, corralled large prey animals into natural confined spaces (such as against

5282-470: Is known to be found 250 km (160 mi) away in the Pyrenees. Unless there was a hausmannite source much closer to Lascaux which has since been depleted, this could mean that there was a local economy based on manganese ores. Also, at Ekain , Basque Country, the inhabitants were using the locally rare manganese mineral groutite in their paintings, which they possibly mined out of the cave itself. Based on

5421-497: Is significant, the differences between island populations best reflect the differences between founders and their genetic diversity that has been passed down through the generations. Founder effects can affect complex traits, such as song diversity. In the Common Myna ( Acridotheres tristis ), the percentage of unique songs within a repertoire and within‐song complexity were significantly lower in birds from founder populations. It

5560-611: Is similar to post-industrial modern northern Europeans. In contrast, in a sample of 21 and 15 late Upper Palaeolithic western European men and women (after the Last Glacial Maximum), the averages were 165.6 cm (5 ft 5 in) and 153.5 cm (5 ft), similar to pre-industrial modern humans. It is unclear why earlier Cro-Magnons were taller, especially considering that cold-climate creatures are short-limbed and thus short-statured to better retain body heat ( Allen's rule ). This has variously been explained as: retention of

5699-507: Is the oldest identified bearer of Y-haplogroup R1b (R1b1a-L754* (xL389,V88)) found in Europe, likely brought in from eastern introgression. The Azilian " Bichon man " skeleton from the Swiss Jura was found to be associated with the WHG lineage. He was a bearer of Y-DNA haplogroup I2a and mtDNA haplogroup U5b1h. Genetic evidence suggests early modern humans interbred with Neanderthals . Genes in

5838-405: Is the original size of the founding colony. Alleles which were present but relatively rare in the original population can move to one of two extremes. The most common one is that the allele is soon lost altogether, but the other possibility is that the allele survives and within a few generations has become much more dispersed throughout the population. The new colony can experience an increase in

5977-561: The Amish populations in the United States exhibit founder effects because they have grown from a very few founders, have not recruited newcomers, and tend to marry within the community. Though still rare, phenomena such as polydactyly (extra fingers and toes, a symptom of a condition such as Weyers acrodental dysostosis or Ellis–Van Creveld syndrome ) are more common in Amish communities than in

6116-613: The Baltic region , and the British Isles were covered in glaciers, and winter sea ice reached the French seaboard. The Alps were also covered in glaciers, and most of Europe was polar desert, with mammoth steppe and forest steppe dominating the Mediterranean coast. Consequently, large swathes of Europe were uninhabitable, and two distinct cultures emerged with unique technologies to adapt to

6255-549: The Great Flood . Following the conception and popularisation of evolution in the mid-to-late 19th century, Cro-Magnons became the subject of much scientific racism , with early race theories allying with Nordicism and Pan-Germanism . Such historical race concepts were overturned by the mid-20th century. During the first wave feminism movement, the Venus figurines were notably interpreted as evidence of some matriarchal religion , though such claims had mostly died down in academia by

6394-570: The Neanderthal 1 fossil discovered in Germany in 1856. Lartet proposed the subspecies name Homo sapiens fossilis in 1869. The term "Cro-Magnon Man" soon came to be used in a general sense to describe the oldest modern people in Europe. By the 1970s, the term was used for any early modern human wherever found, as was the case with the far-flung Jebel Qafzeh remains in Israel and various Paleo-Indians in

6533-815: The Siberian Mal'ta–Buret' culture and Caucasus Hunter-Gatherers (CHG). Most present-day Europeans have a 40–60% WHG ratio, and the 8,000 year old Mesolithic Loschbour man seems to have had a similar genetic makeup. Near Eastern Neolithic farmers which split from the European hunter-gatherers about 40,000 years ago started to spread out across Europe by 8,000 years ago, ushering in the Neolithic with Early European Farmers (EEF). EEF contribute about 30% of ancestry to present-day Baltic populations, and up to 90% in present-day Mediterranean populations. The latter may have inherited WHG ancestry via EEF introgression. The Eastern Hunter-Gatherers (EHG) population identified around

6672-456: The TYRP1 gene associated with lighter hair and eye colour, experienced positive selection as late as 19 to 11 thousand years ago during the Mesolithic transition. The variation of the gene which is associated with blue eyes in present-day European-descended humans, OCA2 , seems to have descended from a common ancestor about 6–10 thousand years ago somewhere in northern Europe. Such a late timing

6811-557: The Toba eruption in Sumatra about 73,000 years ago, covered some parts of India with 3–6 m (10–20 ft) of ash, and must have coated the Nicobar Islands and Andaman Islands , much nearer in the ash fallout cone, with life-smothering layers, forcing the restart of their biodiversity . However, not all founder effect studies are initiated after a natural disaster; some scientists study

6950-494: The biblical chronology . Following Charles Darwin 's 1859 On the Origin of Species , racial anthropologists and raciologists began splitting off putative species and subspecies of present-day humans based on unreliable and pseudoscientific metrics gathered from anthropometry , physiognomy , and phrenology continuing into the 20th century. This was a continuation of Carl Linnaeus ' 1735 Systema Naturae , where he invented

7089-436: The founder effect is the loss of genetic variation that occurs when a new population is established by a very small number of individuals from a larger population. It was first fully outlined by Ernst Mayr in 1942, using existing theoretical work by those such as Sewall Wright . As a result of the loss of genetic variation, the new population may be distinctively different, both genotypically and phenotypically , from

7228-474: The out of Africa expansion which occurred around 65–55 thousand years ago. This movement was an offshoot of the rapid expansion within East Africa associated with mtDNA haplogroup L3 . Mitochondrial DNA analysis places Cro-Magnons as the sister group to Upper Palaeolithic East Asian groups, divergence occurring roughly 50,000 years ago. Initial genomic studies on the earliest Cro-Magnons in 2014, namely on

These aligned well with Nordicism and Pan-Germanism (that is, Aryan supremacy ), which gained popularity just before World War I , and was notably used by the Nazis to justify the conquest of Europe and the supremacy of the German people in World War II .

7784-535: The 1970s. When early modern humans ( Homo sapiens ) migrated onto the European continent, they interacted with the indigenous Neanderthals ( H. neanderthalensis ) which had already inhabited Europe for hundreds of thousands of years. In 2019, Greek palaeoanthropologist Katerina Harvati and colleagues argued that two 210,000 year old skulls from Apidima Cave , Greece, represent modern humans rather than Neanderthals – indicating these populations have an unexpectedly deep history  – but this

7923-631: The 37,000-year-old Kostenki-14 individual, identified 3 major lineages which are also present in present-day Europeans: one related to all later Cro-Magnons; a " Basal Eurasian " lineage which split from the common ancestor of present-day Europeans and East Asians before they split from each other; and another related to a 24,000-year-old individual from the Siberian Mal'ta–Buret' culture (near Lake Baikal ). Contrary to this, Fu et al. (2016), evaluating much earlier European specimens, including Ust'-Ishim and Oase-1 from 45,000 years ago, found no evidence of

It is further debated where the earliest occurrence is identified, with the former hypothesis arguing for Germany about 37,500 years ago, and the latter Buran-Kaya  [ ru ] III rockshelter in Crimea about 38 to 36 thousand years ago. In either case, the appearance of the Gravettian coincides with

8618-660: The Cro-Magnon brain, though within the variation for present-day humans, exhibits longer average frontal lobe length and taller occipital lobe height. The parietal lobes , however, are shorter in Cro-Magnons. It is unclear if this could equate to any functional differences between present-day and early modern humans. In early Upper Palaeolithic western Europe (before the Last Glacial Maximum), 20 men and 10 women were estimated to have averaged 176.2 cm (5 ft 9 in) and 162.9 cm (5 ft 4 in), respectively. This

The Venus figurines  – sculptures of pregnant women with exaggerated breasts and thighs – were used as evidence of

By the beginning of the LGM, the spear-thrower was invented in Europe, which can increase the force and accuracy of the projectile. A possible boomerang made of mammoth tusk was identified in Poland (though it may have been unable to return to the thrower), and dating to 23,000 years ago, it would be the oldest known boomerang. Stone spearheads with leaf- and shouldered-points become more prevalent in

9035-509: The Holocene. The Upper Palaeolithic is characterised by evidence of expansive trade routes and the great distances at which communities could maintain interactions. The early Upper Palaeolithic is especially known for highly mobile lifestyles, with Gravettian groups (at least those analysed in Italy and Moravia, Ukraine) often sourcing some raw materials upwards of 200 km (120 mi). However, it

9174-604: The LGM (such as mammoths, woolly rhinoceroses , Irish elk , and cave lions ), in part contributing to their extinction which occurred by the beginning of or well into the Holocene depending on the species. Most archaeobotanical studies on Pleistocene plant gathering and processing techniques focus on the end of the Paleolithic as precursors to agriculture in the Neolithic. While isotopic studies indicate nearly all nutritional requirements of Palaeolithic populations may have been mostly satisfied by meat, similar to Inuit cuisine ,

9313-607: The LGM, Cro-Magnons are thought to have been much less mobile and featured a higher population density, indicated by seemingly shorter trade routes as well as symptoms of nutritional stress. Cro-Magnons are physically similar to present-day humans, with a globular braincase, completely flat face, gracile brow ridge, and defined chin. However, the bones of Cro-Magnons are somewhat thicker and more robust. The earliest Cro-Magnons often display features that are reminiscent of those seen in Neanderthals . Aurignacians in particular featured

It is unclear, while migrating westward, if they followed the Danube or went along the Mediterranean coast. Beginning about 45,000 years ago, the Proto-Aurignacian culture,

For example, at Lascaux, a painting of a bull had remnants of the manganese mineral hausmannite , which can only be manufactured in heat in excess of 900 °C (1,650 °F), which was probably impossible for Cro-Magnons; this means they likely encountered natural hausmannite which

Following the LGM, population density increased as communities travelled less frequently (though for longer distances), and the need to feed so many more people in tandem with the increasing scarcity of big game caused them to rely more heavily on small or aquatic game ( broad spectrum revolution ), and to more frequently participate in game drive systems and slaughter whole herds at

10008-414: The Palaeolithic whereas women were tasked with child rearing and various domestic works. This would equate to a patriarchal social system. The Palaeolithic matriarchy model was adapted by prominent communist Friedrich Engels , who instead argued that women were robbed of power by men due to economic changes which could only be undone with the adoption of communism ( Marxist feminism ). The former sentiment

10147-611: The Solutrean evolved into the Magdalenian , which would recolonise Western and Central Europe over the next couple thousand years. Starting during the Older Dryas roughly 14,000 years ago, Final Magdalenian traditions appear, namely the Azilian , Hamburgian , and Creswellian . During the Bølling–Allerød warming , Near Eastern genes began showing up in the indigenous Europeans, indicating

10286-628: The Solutrean. Both large and small spearheads were produced in great quantity, and the smaller ones may have been attached to projectile darts . Archery was possibly invented in the Solutrean, though less ambiguous bow technology is first reported in the Mesolithic. Bone technology was revitalised in the Magdalanian, and long-range technology as well as harpoons become much more prevalent. Some harpoon fragments are speculated to have been leisters or tridents , and true harpoons are commonly found along seasonal salmon migration routes. As opposed to

10425-658: The bottleneck is known using the same equation. When a newly formed colony is small, its founders can strongly affect the population's genetic makeup far into the future. In humans, who have a slow reproduction rate, the population will remain small for many generations, effectively amplifying the drift effect generation after generation until the population reaches a certain size. The post-bottleneck population growth rate can be calculated as N ( t ) = K 1 + b e r t {\displaystyle N(t)={K \over 1+be^{rt}}} , where t {\displaystyle t} equals

10564-407: The colony more vulnerable to extinction. The per generation loss of heterozygosity can be calculated as Δ h = − 1 / 2 N {\displaystyle \Delta {h}=-1/2N} , where h {\displaystyle h} equals heterozygosity. The population of the founders of the colony can also be calculated if the loss of heterozygosity from

10703-420: The colony's gene frequency led most scientists to consider the founder effect (and by extension, genetic drift) a significant driving force in the evolution of new species . Sewall Wright was the first to attach this significance to random drift and small, newly isolated populations with his shifting balance theory of speciation. Following behind Wright, Ernst Mayr created many persuasive models to show that

10842-500: The common Eurasian lineage before the divergence of Western and Eastern Eurasians, but after the divergence of the hypothetical Basal-Eurasians. This earliest sample did not cluster with any modern human population, including Africans, and died out without leaving ancestry to modern peoples. The second wave (represented by Bacho Kiro ~45kya) appeared to be more closely related to modern East Asians and Australasians compared to Europeans, suggesting that this lineage split initially after

10981-420: The common ancestry of race or ethnicity or the forced localizations caused by artificial countries inside the larger group of ancestry, hence causing an original founder effect. Race and specific founder effect mutation diseases are found in all races or ethnicities, and country-specific mutation diseases are caused by increasing homozygosity (the existence of same gene on both chromosomes pairs, hence

11120-572: The concept of grave goods . Analysis of the pathology of the skeletons shows that the humans of this period led a physically difficult life. In addition to infection, several of the individuals found at the shelter had fused vertebrae in their necks, indicating traumatic injury; the adult female found at the shelter had survived for some time with a skull fracture. As these injuries would be life-threatening even today, this suggests that Cro-Magnons relied on community support and took care of each other's injuries. In addition, Cro-Magnon 1 suffered from

11259-569: The continent. This wave of modern humans replaced Neanderthals and their Mousterian culture. In the Danube Valley, Aurignacian sites are few and far between, compared to later traditions, until 35,000 years ago. From here, the "Typical Aurignacian" becomes quite prevalent, and extends until 29,000 years ago. Gradually replaced by the Gravettian culture, the close of the Aurignacian is poorly defined. "Aurignacoid" or "Epi-Aurignacian" tools are identified as late as 18 to 15 thousand years ago. It

11398-464: The decline in genetic variation and small population size accompanying the founder effect were critically important for new species to develop. However, much less support for this view is shown today, since the hypothesis has been tested repeatedly through experimental research, and the results have been equivocal at best. Speciation by genetic drift is a specific case of peripatric speciation which in itself occurs in rare instances. It takes place when

11537-815: The deported Acadians and migrants coming from the British Isles. Since the 20th century, immigration in Quebec and mixing of French Canadians involve people from all over the world. While the French Canadians of Quebec today may be partly of other ancestries, the genetic contribution of the original French founders is predominant, explaining about 90% of regional gene pools, while Acadian (descended from other French settlers in eastern Canada) admixtures contributing 4% British and 2% Native American and other groups contributing less. In humans, founder effects can arise from cultural isolation, and inevitably, endogamy . For example,

11676-576: The discovery before the meeting of the Society of Anthropology of Paris on 21 May, the proceedings published in its journal Bulletins et Mémoires de la Société d'Anthropologie de Paris . He described the site as a cemetery and identified the humans as cave dwellers . The site is called Abri de Cro-Magnon (Cro-Magnon rock shelter), now recognised as a UNESCO World Heritage Site . Abri means "rock shelter" in French, cro means "hole" in Occitan , and Magnon

11815-555: The distribution of Mediterranean and Atlantic seashell jewellery even well inland, there may have been a network during the Late Glacial Interstadial (14 to 12 thousand years ago) along the rivers Rhine and Rhône in France, Germany, and Switzerland. Cro-Magnon cave sites quite often feature distinct spatial organisation, with certain areas specifically designated for specific activities, such as hearth areas, kitchens, butchering grounds, sleeping grounds, and trash pile. It

11954-512: The earliest attempts to classify Cro-Magnons was done by racial anthropologists Joseph Deniker and William Z. Ripley in 1900, who characterised them as tall and intelligent proto- Aryans , superior to other races, who descended from Scandinavia and Germany. Further race theories revolved around progressively lighter, blonder, and superior races evolving in Central Europe and spreading out in waves to replace their darker ancestors, culminating in

12093-416: The effects on limb length and perch width, both widely varying phenotypic ranges in the parent population. Unfortunately, immigration did occur, but the founder effect and adaptive differentiation, which could eventually lead to peripatric speciation, were statistically and biologically significant between the island populations after a few years. The authors also point out that although adaptive differentiation

12232-594: The end of Europe's genetic isolation. Possibly due to the continual reduction of European big game, the Magdalenian and Epi-Gravettian were completely replaced by the Mesolithic by the beginning of the Holocene. Europe was completely re-peopled during the Holocene climatic optimum from 9 to 5 thousand years ago. Mesolithic Western Hunter-Gatherers (WHG) contributed significantly to the present-day European genome, alongside Ancient North Eurasians (ANE) which descended from

12371-427: The end of the Palaeolithic which suggest the inhabitants were harvesting acorn , almond , pistacia , hawthorn , wild pear , blackthorn , rosehip , sorbus , and grape . Multiple German sites bear evidence of wild cherry , blackberry , dewberry , and raspberry consumption. The Palaeolithic archaeobotanical record becomes sparser farther north, but water caltrop and water lily tubers are consumed at least in

12510-489: The first early modern humans ( Homo sapiens ) to settle in Europe, migrating from western Asia, continuously occupying the continent possibly from as early as 56,800 years ago. They interacted and interbred with the indigenous Neanderthals ( H. neanderthalensis ) of Europe and Western Asia, who went extinct 40,000 to 35,000 years ago. The first wave of modern humans in Europe ( Initial Upper Paleolithic ) left no genetic legacy to modern Europeans; however, from 37,000 years ago

12649-604: The first widely recognised European Upper Palaeolithic culture, spread out across Europe, probably descending from the Near-Eastern Ahmarian culture. The Aurignacian industry took hold perhaps in south-central Europe sometime after 40,000 years ago, with the onset of Heinrich event 4 (a period of extreme seasonality) and the Campanian Ignimbrite eruption near Naples (which covered eastern Europe in ash). The Aurignacian culture rapidly replaced others across

12788-489: The five skeletons discovered by French palaeontologist Louis Lartet in 1868 at the Cro-Magnon rock shelter , Les Eyzies , Dordogne, France, after the area was accidentally discovered while a road was constructed for a railway station. Remains of Palaeolithic cultures have been known for centuries, but they were initially interpreted in a creationist model, wherein they represented antediluvian peoples which were wiped out by

12927-442: The formation of Eastern Eurasians, and migrated instead northwestwards into Europe. This lineage similarly did not contribute ancestry to later populations, and was replaced by a West-Eurasian lineage (~40kya), which expanded into Europe and Siberia . Proper Aurignacian people (40-26kya) were still part of a large Western Eurasian "meta-population", related to Paleolithic Siberian and Western Asian populations. Earlier samples (such as

13066-423: The frequency of recessive alleles, as well, and as a result, an increased number who are homozygous for certain recessive traits. The equation to calculate reccessive allele frequencies is q ^ = √ N 22 / N {\displaystyle {\hat {q}}=\surd N_{22}/N} based on Hardy-Wienberg assumptions. The variation in gene frequency between

13205-402: The gene pool in his review of the relevant morphology. For 28 modern human specimens from 190 to 25 thousand years ago, average brain volume was estimated to have been about 1,478 cc (90.2 cu in), and for 13 Cro-Magnons about 1,514 cc (92.4 cu in). In comparison, present-day humans average 1,350 cc (82 cu in), which is notably smaller. This is because

13344-464: The grave of a Pavlovian site in Brno, Czech Republic (it is also the only statuette found in a Palaeolithic grave). 2-D Magdalenian engravings from 15 to 11 thousand years ago do depict males, indicated by an erect penis and facial hair, though profiles of women with an exaggerated buttock are much more common. There are less than 100 depictions of males in the Cro-Magnons archaeological record (of them, about

13483-429: The importance of male contributions of food to the group. As this was published during the second-wave feminism movement, this was quickly met with backlash from many female anthropologists. Among these was Australian archaeologist Betty Meehan in her 1974 article Woman the Gatherer , who argued that women play a vital role in these communities by gathering more reliable food plants and small game, as big game hunting has

13622-489: The importance of plants may have varied greatly depending on local climatic conditions. The Palaeolithic archaeobotanical record outside Europe (especially in the Middle East) shows these peoples were capable of processing a massive range of plant resources, in the 20,000 year old Israeli Ohalo II site as many as 150 types of seeds, fruits, nuts, and starches. There are several European Mediterranean cave sites dating to near

13761-442: The inhabited lands farther south by the powerful floodwaters. Buckland assumed the specimen was a woman because he was adorned with jewellery (shells, ivory rods and rings, and a wolf-bone skewer), and Buckland also stated (possibly in jest) the jewellery was evidence of witchcraft . Around this time, the uniformitarianism movement was gaining traction, headed principally by Charles Lyell , arguing that fossil materials well predated

13900-540: The issue of offsetting protein poisoning (nitrogen overloading) by eating fatty foods ( blubber most especially in the Inuit diet) becomes problematic in more temperate climates with leaner prey. The isotopic score for Palaeolithic peoples are comparable to Inuit with a diet comprising 1–4% plant components, but also to Onge from the tropical Andaman Islands , Paraguayan Aché , Arnhem Land Aboriginals, and Venezuelan Hiwi whose diets comprise up to 25% plant components. Thus,

14039-626: The maternal – resulting in a matrilineal (and matriarchal) society. Matriarchs were then conquered by patriarchs at the dawn of civilisation. The switch from matriarchy to patriarchy and the hypothetical adoption of monogamy was seen as a leap forward. However, when the first Palaeolithic representations of humans were discovered, the so-called Venus figurines – which typically feature pronounced breasts, buttocks, and vulvas (areas generally sexualised in present-day Western Culture) – they were initially interpreted as pornographic in nature. The first Venus discovered

14178-418: The matriarchy hypothesis have also been prominent, such as American religious scholar Cynthia Eller's 2000 The Myth of Matriarchal Prehistory . Looking at the archaeological record, depictions of women are markedly more common than of men. In contrast to the commonplace Venuses in the Gravettian, Gravettian depictions of men are rare and contested, the only reliable one being a fragmented ivory figurine from

14317-442: The mid-Upper-Palaeolithic. Nonetheless, Magdalenian peoples appear to have had a greater dependence on small animals, aquatic resources, and plants than predecessors, probably due to the relative scarcity of European big game following the LGM ( Quaternary extinction event ). It is possible that human activity, in addition to the rapid retreat of favourable steppeland, inhibited recolonisation of most of Europe by megafauna following

14456-483: The modern classification system, in doing so classifying humans as Homo sapiens with several putative subspecies classifications for different races based on racist behavioural definitions (in accord with historical race concepts ): " H. s. europaeus " (European descent, governed by laws), " H. s. afer " (African descent, impulse), " H. s. asiaticus " (Asian descent, opinions), and " H. s. americanus " (Native American descent, customs). The racial classification system

14595-588: The most related to one another. These results are promising, as the island of Corsica was repopulated with red deer from the Sardinian island after the original Corsican red deer population became extinct, and the deer now inhabiting the island of Corsica are diverging from those inhabiting Sardinia. Kolbe and others set up a pair of genetically sequenced and morphologically examined lizards on seven small islands to watch each new population's growth and adaptation to its new environment. Specifically, they were looking at

14734-522: The new environment: the Solutrean in southwestern Europe, which invented brand new technologies, and the Epi-Gravettian from Italy to the East European Plain , which adapted the previous Gravettian technologies. Solutrean peoples inhabited the permafrost zone, whereas Epi-Gravettian peoples appear to have stuck to less harsh, seasonally frozen areas. Relatively few sites are known through this time. The glaciers began retreating about 20,000 years ago, and

14873-433: The nickname of the "two-toed tribe". The island of Pingelap also suffered a population bottleneck in 1775 following a typhoon that had reduced the population to only 20 people. As a result, complete achromatopsia has a current rate of occurrence of roughly 10%, with an additional 30% being carriers of this recessive condition. Around 1814, a small group of British colonists founded a settlement on Tristan da Cunha ,

15012-469: The northern European Mesolithic. It is unclear to what extent they would process or pretreat otherwise inedible plants which require multiple steps (such as a combination of fermenting, grinding, boiling, etc.). For weapons, Cro-Magnons crafted spearpoints using predominantly bone and antler, possibly because these materials were readily abundant. Compared to stone, these materials are compressive, making them fairly shatterproof. These were then hafted onto

15151-507: The number of generations, r {\displaystyle r} is the growth rate, K {\displaystyle K} is the population equilibrium size, e {\displaystyle e} is the natural logarithm base, and b {\displaystyle b} is the constant ( K − N 0 ) / N 0 {\displaystyle (K-N_{0})/N_{0}} , where N 0 {\displaystyle N_{0}}

15290-454: The original population and colony may also trigger the two groups to diverge significantly over the course of many generations. As the variance, or genetic distance , increases, the two separated populations may become distinctively different, both genetically and phenotypically , although not only genetic drift, but also natural selection, gene flow and mutation all contribute to this divergence. This potential for relatively rapid changes in

15429-497: The original population. A population bottleneck may also cause a founder effect, though it is not strictly a new population. The founder effect occurs when a small group of migrants—not genetically representative of the population from which they came—establish in a new area. In addition to founder effects, the new population is often very small , so it shows increased sensitivity to genetic drift , an increase in inbreeding , and relatively low genetic variation . In genetics ,

15568-429: The overwhelming majority of Palaeolithic people (both Neanderthals and modern humans) died before reaching the age of 40, with few elderly individuals recorded. It is possible the population boom was caused by a significant increase in fertility rates. A 2005 study estimated the population of Upper Palaeolithic Europe by calculating the total geographic area which was inhabited based on the archaeological record; averaged

15707-399: The parent population from which it is derived. In extreme cases, the founder effect is thought to lead to the speciation and subsequent evolution of new species. In the figure shown, the original population has nearly equal numbers of blue and red individuals. The three smaller founder populations show that one or the other color may predominate (founder effect), due to random sampling of

15846-490: The patrilineal (from father to son) Y-DNA haplogroups the earliest C1 , the latest IJ , and K2a ; and matrilineal (from mother to child) mt-DNA haplogroup N , R , and U . Y-haplogroup IJ descended from Southwest Asia. Haplogroup I emerged about 35 to 30 thousand years ago, either in Europe or West Asia. Mt-haplogroup U5 arose in Europe just prior to the LGM, between 35 and 25 thousand years ago. The 14,000 year old Villabruna 1 skeleton from Ripari Villabruna , Italy,

15985-641: The population density of Chipewyan , Hän , Hill people , and Naskapi Native Americans which live in cold climates and applied to this to Cro-Magnons; and assumed that population density continually increased with time calculated by the change in the number of total sites per time period. The study calculated that: from 40 to 30 thousand years ago the population was roughly 1,700–28,400 (average 4,400); from 30 to 22 thousand years ago roughly 1,900–30,600 (average 4,800); from 22 to 16.5 thousand years ago roughly 2,300–37,700 (average 5,900); and 16.5–11.5 thousand years ago roughly 11,300–72,600 (average 28,700). Following

16124-630: The presence of the " Negroid race " in Palaeolithic Europe, because they were interpreted as having been based on real women with steatopygia (a condition which causes thicker thighs, common in the women of the San people of Southern Africa) and the hairdos of some are supposedly similar to some seen in Ancient Egypt . By the 1940s, the positivism movement – which fought to remove political and cultural bias from science and had begun about

16263-434: The present-day European genome and were more closely related to present-day Europeans than East Asians. Earlier Cro-Magnons (10 tested in total), on the other hand, did not seem to be ancestral to any present-day population, nor did they form any cohesive group in and of themselves, each representing either completely distinct genetic lineages, admixture between major lineages, or have highly divergent ancestry. Because of these,

16402-620: The present-day average. The earliest Cro-Magnon specimens also exhibit some features that are reminiscent of those found in Neanderthals. The first Cro-Magnons would have had darker skin tones than most modern Europeans; natural selection for lighter skin would not have begun until 30,000 years ago. Before the LGM, Cro-Magnons had overall low population density, tall stature similar to post-industrial humans, and expansive trade routes stretching as long as 900 km (560 mi), and hunted big game animals. Cro-Magnons had much higher populations than

16541-463: The present-day genome are estimated to have entered about 65 to 47 thousand years ago, most likely in West Asia soon after modern humans left Africa. In 2015, the 40,000 year old modern human Oase 1 was found to have had 6–9% ( point estimate 7.3%) Neanderthal DNA, indicating a Neanderthal ancestor up to four to six generations earlier, but this hybrid Romanian population does not appear to have made

16680-618: The reinstatement of a species that became locally extinct or hadn't existed there before. A study has been in place since 1958 studying the wolf/moose interaction on Isle Royale in Lake Superior after those animals naturally migrated there, perhaps on winter ice. Hajji and others, and Hundertmark & Van Daele, studied the current population statuses of past founder effects in Corsican red deer and Alaskan elk, respectively. Corsican red deer are still listed as an endangered species , decades after

16819-433: The rock shelter. French geologist Louis Lartet was called for excavations, and found the partial skeletons of four prehistoric adults and one infant, along with perforated shells used as ornaments, an object made from ivory, and worked reindeer antler. These "Cro-Magnon men" were identified as the prehistoric human species of Europe, as distinct from Neanderthal Man , described a few years earlier by William King based on

16958-427: The specimen names and called Cro-Magnon 1 Le Vieillard , from which the name "Old Man" became popularly used. After complete analyses of individual bones by early 2000s, it became generally agreed that the rock shelter contained 140 human remains from at least eight individuals: four adults and four infant. Fossils and artifacts from the Palaeolithic had actually been known for decades, but these were interpreted in

17097-691: The steppes of the Urals also dispersed, and the Scandinavian Hunter-Gatherers appear to be a mix of WHG and EHG. Around 4,500 years ago, the immigration of the Yamnaya and Corded Ware cultures from the eastern steppes brought the Bronze Age , the Proto-Indo-European language , and more or less the present-day genetic makeup of Europeans. In 1863, a railway was constructed leading to Les Eyzies,

17236-470: The study also concluded that, beginning roughly 37,000 years ago, Cro-Magnons descended from a single founder population and were reproductively isolated from the rest of the world. The study reported that an Aurignacian individual from Grottes de Goyet , Belgium, has more genetic affinities to the Magdalenian inhabitants of Cueva de El Mirón , Spain, than to more or less contemporaneous eastern European Gravettians. Haplogroups identified in Cro-Magnons are

17375-441: The study of island biogeography and island ecology . A natural "blank slate" is not easily found, but a classic series of studies on founder population effects was done following the catastrophic 1883 eruption of Krakatoa , which erased all life on the island. Another continuing study has been following the biocolonization of Surtsey , Iceland , a new volcanic island that erupted offshore between 1963 and 1967. An earlier event,

17514-416: The view in European thought that the civilised white man had descended from primitive, low browed ape ancestors through a series of savage races. Prominent brow-ridges were classified as an ape-like trait; consequently, Neanderthals (as well as Aboriginal Australians ) were considered a lowly race. These European fossils were considered to have been the ancestors to specifically living European races. Among

17653-674: The west, due to major climatic degradation during the Last Glacial Maximum (LGM), peaking 21,000 years ago. As Europe warmed, the Solutrean evolved into the Magdalenian by 20,000 years ago, and these peoples recolonised Europe. The Magdalenian and Epi-Gravettian gave way to Mesolithic cultures as big game animals were dying out and the Last Glacial Period drew to a close. Cro-Magnons were anatomically similar to present-day Europeans, West Asians, and North Africans; however, they were more robust, having larger brains, broader faces, more prominent brow ridges , and bigger teeth, compared to

17792-400: The western Gravettian , Solutrean and Aurignacian cultures. There is a notable technological complexification coinciding with the replacement of Neanderthals with Cro-Magnons in the archaeological record, and so the terms "Middle Palaeolithic" and "Upper Palaeolithic" were created to distinguish between these two time periods. Largely based on western European archaeology, the transition

17931-469: The work and informed the government officials of the discovery. He also informed a local geologist, Abel Laganne, who recovered ornaments, more flints, and two human skulls. As assigned by the French Minister of Public Instruction Victor Duruy to verify the finds, Louis Lartet made systematic excavation and discovered additional human remains, animal bones, stone tools, and ornaments. He deliberated

18070-512: Was a movement of ideas but not people between Europe and Siberia. At the 30,000 year old Romanian Poiana Cireşului site, perforated shells of the Homalopoma sanguineum sea snail were recovered, which is significant as it inhabits the Mediterranean at nearest 900 km (560 mi) away. Such interlinkage may have been an important survival tool, with the steadily deteriorating climate. Given low estimated population density, this may have required

18209-501: Was a slow progression initiating far earlier than the Upper Paleolithic, especially when considering the non-European archaeological record. Practices considered modern include: the production of microliths , the common use of bone and antler, the common use of grinding and pounding tools, high quality evidence of body decoration and figurine production, long-distance trade networks, and improved hunting technology. In regard to art,

18348-521: Was adopted by the first-wave feminism movement, who attacked the patriarchy by making Darwinist arguments of a supposed natural egalitarian or matrifocal state of human society instead of patriarchal, as well as interpreting the Venuses as evidence of mother goddess worship as part of some matriarchal religion . Consequently, by the mid-20th century, the Venuses were primarily interpreted as evidence of some Palaeolithic fertility cult. Such claims died down in

18487-424: Was disputed in 2020 by French paleoanthropologist Marie-Antoinette de Lumley  [ fr ] and colleagues. About 60,000 years ago, marine isotope stage 3 began, characterised by oscillating climatic patterns, causing sudden retreat and recolonisation phases in vegetation, fluctuating between forestland and open steppeland. The earliest indication of Upper Palaeolithic modern human migration into Europe

18626-480: Was dubbed the "Upper Palaeolithic Revolution," (extended to be a worldwide phenomenon) and the idea of " behavioural modernity " became associated with this event and early modern cultures. It is largely agreed that the Upper Palaeolithic seems to feature a higher rate of technological and cultural evolution than the Middle Palaeolithic, but it is debated if behavioural modernity was truly an abrupt development or

18765-652: Was found by Tarr et al. (1998) that the loss of heterozygosity of the Laysan finch ( Telespiza cantans ) after founding events on small islands in the Pacific Ocean closely matched theoretical calculations upon examination of microsatellite loci. Genetic studies of founder effect have concentrated on discovering ancestral and novel genetic diseases caused by founder effect and, to a lesser degree, on ancestry-related founder effects on populations, races, and ancient migrations, as well other aspects. The founder population could be

18904-505: Was named the " Vénus impudique " ("immodest Venus") by the discoverer Paul Hurault, 8th Marquis de Vibraye , because it lacked clothes and had a prominent vulva. The name " Venus ", after the Roman goddess of beauty, in itself implies an erotic function. Such a pattern in the representation of the human form led to suggestions that human forms were generally pornography for men, meaning men were primarily responsible for artwork and craftsmanship in

19043-477: Was potentially caused by overall low population and/or low cross-continental movement required for such an adaptive shift in skin, hair, and eye colouration. However, KITLG experienced positive selection in Cro-Magnons (as well as East Asians) beginning approximately 30,000 years ago. While anatomically modern humans have been present outside of Africa during some isolated time intervals potentially as early as 250,000 years ago, present-day non-Africans descend from

19182-449: Was quickly extended to fossil specimens, including both Cro-Magnons and the Neanderthals, after the true extent of their antiquity was recognised. In 1869, Lartet had proposed the subspecies classification " H. s. fossilis " for the Cro-Magnon remains. Other supposed fossil human species included (among many others): " H. pre-aethiopicus " for a skull from Dordogne which had "Ethiopic affinities"; " H. predmosti " or " H. predmostensis " for

19321-673: Was the landowner. The original human remains were brought to and preserved at the National Museum of Natural History in Paris. The number of individuals at the Cro-Magnon rock shelter has eluded scientists for over a century. The original workers reported that they found 15 skeletons. In his report, Lartet identified five individuals based on the skulls, three of them males (designated Cro-Magnon 1, 3 and 4), one female (Cro-Magnon 2) and an infant (Cro-Magnon 5). In 1868, anatomist Paul Broca noted five adults and several infants. Broca introduced
