94-543: Zoonomia; or the Laws of Organic Life (1794–96) is a two-volume medical work by Erasmus Darwin dealing with pathology , anatomy , psychology , and the functioning of the body. Its primary framework is one of associationist psychophysiology . The book is now best remembered for its early ideas relating to the theory of evolution , specifically forms of developmentalism similar to Lamarckism . However, despite Erasmus Darwin's familial connection as grandfather to Charles Darwin ,
188-421: A boarding school for girls. In 1782, Mary Sr (the governess) married Joseph Day (1745–1811), a Birmingham merchant, and moved away. There was also a rumour that Darwin fathered another child, this time with a married woman. A Lucy Swift gave birth in 1771 to a baby, also named Lucy, who was christened a daughter of her mother and William Swift. It has been suggested that the father was really Darwin. However, it
282-615: A deist . The philosopher of biology Michael Ruse described Lamarck, "as believing in God as an unmoved mover, creator of the world and its laws, who refuses to intervene miraculously in his creation." Biographer James Moore described Lamarck as a "thoroughgoing deist". The historian Jacques Roger has written, "Lamarck was a materialist to the extent that he did not consider it necessary to have recourse to any spiritual principle... his deism remained vague, and his idea of creation did not prevent him from believing everything in nature, including
376-455: A botany book by James Francis Chomel. With a reduced pension of only 400 francs a year, Lamarck resolved to pursue a profession. He attempted to study medicine, and supported himself by working in a bank office. Lamarck studied medicine for four years, but gave it up under his elder brother's persuasion. He was interested in botany , especially after his visits to the Jardin du Roi , and he became
470-823: A concept not to be seen again until one century later. [REDACTED] Erasmus Darwin House , his home in Lichfield , Staffordshire, is a museum dedicated to him and his life's work. A secondary school at Burntwood, near Lichfield, was renamed Erasmus Darwin Academy in 2011. A science building on the Clifton campus of Nottingham Trent University is named after him. Jean-Baptiste Lamarck Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck ( / l ə ˈ m ɑːr k / ; French: [ʒɑ̃batist lamaʁk] ),
564-435: A eulogy to denigrate Lamarck: [Cuvier's] éloge of Lamarck is one of the most deprecatory and chillingly partisan biographies I have ever read—though he was supposedly writing respectful comments in the old tradition of de mortuis nil nisi bonum . While he was working on Hydrogéologie (1802), Lamarck had the idea to apply the principle of erosion to biology. This led him to the basic principle of evolution, which saw
658-421: A few fleeting passages that look upon organic transmutation with favor." From thus meditating on the great similarity of the structure of the warm-blooded animals, and at the same time of the great changes they undergo both before and after their nativity; and by considering in how minute a proportion of time many of the changes of animals above described have been produced; would it be too bold to imagine, that in
752-543: A force adapting animals to their local environments and differentiating them from each other. He believed that these forces must be explained as a necessary consequence of basic physical principles, favoring a materialistic attitude toward biology. Lamarck referred to a tendency for organisms to become more complex, moving "up" a ladder of progress . He referred to this phenomenon as Le pouvoir de la vie or la force qui tend sans cesse à composer l'organisation (The force that perpetually tends to make order). Lamarck believed in
846-475: A major work on the classification of invertebrates. In the work, he introduced definitions of natural groups among invertebrates. He categorized echinoderms , arachnids , crustaceans , and annelids , which he separated from the old taxon for worms known as Vermes . Lamarck was the first to separate arachnids from insects in classification, and he moved crustaceans into a separate class from insects. In 1802, Lamarck published Hydrogéologie , and became one of
940-444: A more well-established alternative. Lamarck is usually remembered for his belief in the then commonly held theory of inheritance of acquired characteristics , and the use and disuse model by which organisms developed their characteristics. Lamarck incorporated this belief into his theory of evolution, along with other common beliefs of the time, such as spontaneous generation. The inheritance of acquired characteristics (also called

His siblings were: He was educated at Chesterfield Grammar School, then later at St John's College , Cambridge . He obtained his medical education at the University of Edinburgh Medical School . Darwin settled in 1756 as a physician at Nottingham, but met with little success and so moved

#17328725022131128-449: A role for use and disuse as an evolutionary mechanism subsidiary to natural selection, most often in respect of disuse . He praised Lamarck for "the eminent service of arousing attention to the probability of all change in the organic... world, being the result of law, not miraculous interposition". Lamarckism is also occasionally used to describe quasi-evolutionary concepts in societal contexts, though not by Lamarck himself. For example,
1222-506: A small element of his theory of evolution, and was in his time accepted by many natural historians. Lamarck's contribution to evolutionary theory consisted of the first truly cohesive theory of biological evolution, in which an alchemical complexifying force drove organisms up a ladder of complexity, and a second environmental force adapted them to local environments through use and disuse of characteristics, differentiating them from other organisms. Scientists have debated whether advances in
1316-592: A student under Bernard de Jussieu , a notable French naturalist. Under Jussieu, Lamarck spent 10 years studying French flora. In 1776, he wrote his first scientific essay—a chemical treatise. After his studies, in 1778, he published some of his observations and results in a three-volume work, entitled Flore française . Lamarck's work was respected by many scholars, and it launched him into prominence in French science. On 8 August 1778, Lamarck married Marie Anne Rosalie Delaporte. Georges-Louis Leclerc, Comte de Buffon , one of

Erasmus Darwin's works were read and commented on by his grandson Charles Darwin the naturalist. Erasmus Darwin based his theories on David Hartley 's psychological theory of associationism . The essence of his views

Darwin, the description reads, "was of middle stature, in person gross and corpulent; his features were coarse, and his countenance heavy; if not wholly void of animation, it certainly was by no means expressive. The print of him, from a painting of Mr. Wright, is a good likeness. In his gait and dress he

Encyclopedia-style entries on various diseases explain their symptoms and underlying mechanics, followed by suggestions for treatment. After the fourth class of diseases, Darwin presents a lengthy explanation of his own theory of fever, which he says "may be termed

Lucy Swift, later known as Lucy Hardcastle after her marriage, went on to be known as a botanist and teacher. In 1775, Darwin met Elizabeth Pole, daughter of Charles Colyear, 2nd Earl of Portmore , and wife of Colonel Edward Pole (1718–1780); but as she
1880-410: Is now called soft inheritance , the inheritance of acquired characteristics, or simply "Lamarckism", though it forms only a part of Lamarck's thinking. However, in the field of epigenetics , evidence is growing that soft inheritance plays a part in the changing of some organisms' phenotypes; it leaves the genetic material ( DNA ) unaltered (thus not violating the central dogma of biology ) but prevents
1974-407: Is remembered, at least in malacology , as a taxonomist of considerable stature. The modern era generally remembers Lamarck for a theory of inheritance of acquired characteristics , called Lamarckism (inaccurately named after him), soft inheritance, or use/disuse theory, which he described in his 1809 Philosophie zoologique . However, the idea of soft inheritance long antedates him, formed only

According to the paleontologist Henry Fairfield Osborn , "Lamarck denied, absolutely, the existence of any 'perfecting tendency' in nature, and regarded evolution as
2162-464: The Muséum national d'Histoire naturelle in 1793, Lamarck became a professor of zoology . In 1801, he published Système des animaux sans vertèbres , a major work on the classification of invertebrates , a term which he coined. In an 1802 publication, he became one of the first to use the term " biology " in its modern sense. Lamarck continued his work as a premier authority on invertebrate zoology . He
2256-407: The memetic theory of cultural evolution is sometimes described as a form of Lamarckian inheritance of nongenetic traits. During his lifetime, Lamarck named a large number of species, many of which have become synonyms. The World Register of Marine Species gives no fewer than 1,634 records. The Indo-Pacific Molluscan Database gives 1,781 records. Among these are some well-known families such as
2350-477: The struggle for existence . His poetry was admired by Wordsworth , while Coleridge was intensely critical, writing, "I absolutely nauseate Darwin's poem". It often made reference to his interests in science; for example botany and steam engines . The last two leaves of Darwin's A plan for the conduct of female education in boarding schools (1797) contain a book list, an apology for the work, and an advert for "Miss Parkers School". The school advertised on
2444-477: The "three great objects of desire" for every organism: "lust, hunger, and security." A similar "survival of the fittest" view in Zoönomia is Erasmus' view on how a species "should" propagate itself. Erasmus' idea that "the strongest and most active animal should propagate the species, which should thence become improved". Today, this is called the theory of survival of the fittest . His grandson Charles Darwin posited
2538-504: The Academie for financial assistance. Lamarck was buried in a common grave of the Montparnasse cemetery for just five years, according to the grant obtained from relatives. Later, the body was dug up along with other remains and was lost. Lamarck's books and the contents of his home were sold at auction, and his body was buried in a temporary lime pit. After his death, Cuvier used the form of
2632-518: The English names of plants that we use today. Darwin then wrote The Loves of the Plants , a long poem, which was a popular rendering of Linnaeus' works. Darwin also wrote Economy of Vegetation , and together the two were published as The Botanic Garden . Among other writers he influenced were Anna Seward and Maria Jacson . Darwin's most important scientific work, Zoonomia (1794–1796), contains

This took seven years. The result was two publications: A System of Vegetables between 1783 and 1785, and The Families of Plants in 1787. In these volumes, Darwin coined many of
2820-755: The Lunar Society, and especially Darwin, opposed the slave trade . He attacked it in The Botanic Garden (1789–1791), and in The Loves of Plants (1789), The Economy of Vegetation (1791), and the Phytologia (1800). In 1761, Darwin was elected a fellow of the Royal Society . In addition to the Lunar Society, Erasmus Darwin belonged to the influential Derby Philosophical Society , as did his brother-in-law Samuel Fox (see family tree below). He experimented with

He set out to develop an explanation, and on 11 May 1800 (the 21st day of Floreal , Year VIII, in the revolutionary timescale used in France at the time), he presented a lecture at the Muséum national d'histoire naturelle in which he first outlined his newly developing ideas about evolution. In 1801, he published Système des Animaux sans Vertèbres ,
3102-468: The Royal Garden, and also other objects of natural history, such as minerals and ores, that were not found in French museums. On 7 January 1786, his second son, Antoine, was born, and Lamarck chose Antoine Laurent de Jussieu , Bernard de Jussieu's nephew, as the boy's godfather. On 21 April the following year, Charles René, Lamarck's third son, was born. René Louiche Desfontaines , a professor of botany at
3196-404: The Royal Garden, was the boy's godfather, and Lamarck's elder sister, Marie Charlotte Pelagie De Monet, was the godmother. In 1788, Buffon's successor at the position of Intendant of the Royal Garden, Charles-Claude Flahaut de la Billaderie, comte d'Angiviller , created a position for Lamarck, with a yearly salary of 1,000 francs, as the keeper of the herbarium of the Royal Garden.

The International Plant Names Index gives 58 records, including a number of well-known genera such as the mosquito fern ( Azolla ). The honeybee subspecies Apis mellifera lamarckii is named after Lamarck, as well as the bluefire jellyfish ( Cyaneia lamarckii ). A number of plants have also been named after him, including Amelanchier lamarckii (juneberry), Digitalis lamarckii , and Aconitum lamarckii , as well as
3384-585: The army after being injured in 1766, and returned to his medical studies. Lamarck developed a particular interest in botany, and later, after he published the three-volume work Flore françoise (1778), he gained membership of the French Academy of Sciences in 1779. Lamarck became involved in the Jardin des Plantes and was appointed to the Chair of Botany in 1788. When the French National Assembly founded

In his first six years as professor, Lamarck published only one paper, in 1798, on the influence of the moon on the Earth's atmosphere. Lamarck began as an essentialist who believed species were unchanging; however, after working on the molluscs of
3572-595: The broader world. An example is Susanna Wright , who was raised in Lancashire and became an American colonist associated with the Midlands Enlightenment. It is not known whether Darwin and Wright knew each other, although they definitely knew many people in common. Other women who received substantial education and who participated in the broader world (albeit sometimes anonymously) whom Darwin definitely knew were Maria Jacson and Anna Seward . These dates indicate
3666-530: The cause of all organic life? In Zoonomia , Erasmus Darwin advocated the inheritance of acquired characteristics . He stated, "[F]rom their first rudiment, or primordium, to the termination of their lives, all animals undergo perpetual transformations; which are in part produced by their own exertions in consequence of their desires and aversions, of their pleasures and their pains, or of irritations, or of associations; and many of these acquired forms or propensities are transmitted to their posterity." This statement
3760-445: The classical four elements . During Lamarck's lifetime, he became controversial, attacking the more enlightened chemistry proposed by Lavoisier . He also came into conflict with the widely respected palaeontologist Georges Cuvier , who was not a supporter of evolution. According to Peter J. Bowler , Cuvier "ridiculed Lamarck's theory of transformation and defended the fixity of species." According to Martin J. S. Rudwick : Cuvier

A governess , Mary Parker, was hired to look after Robert. By late 1771, employer and employee had become intimately involved and together they had two illegitimate daughters: Susanna and Mary Jr later established
4136-411: The different and fuller theory of natural selection. Charles' theory was that natural selection is the inheritance of changed genetic characteristics that are better adaptations to the environment; these are not necessarily based in "strength" and "activity", which themselves ironically can lead to the overpopulation that results in natural selection yielding nonsurvivors of genetic traits. Erasmus Darwin
4230-413: The expression of genes , such as by methylation to modify DNA transcription ; this can be produced by changes in behaviour and environment. Many epigenetic changes are heritable to a degree. Thus, while DNA itself is not directly altered by the environment and behavior except through selection, the relationship of the genotype to the phenotype can be altered, even across generations, by experience within
4324-598: The field of transgenerational epigenetics mean that Lamarck was to an extent correct, or not. Jean-Baptiste Lamarck was born in Bazentin , Picardy , northern France, as the 11th child in an impoverished aristocratic family. Male members of the Lamarck family had traditionally served in the French army. Lamarck's eldest brother was killed in combat at the Siege of Bergen op Zoom , and two other brothers were still in service when Lamarck
4418-425: The final necessary effect of surrounding conditions on life." Charles Coulston Gillispie , a historian of science, has written "life is a purely physical phenomenon in Lamarck", and argued that Lamarck's views should not be confused with the vitalist school of thought. The second component of Lamarck's theory of evolution was the adaptation of organisms to their environment. This could move organisms upward from
4512-409: The first sentence of the 1818 Preface to Frankenstein to support his contention that the creation of life is possible. His wife Mary Shelley in her introduction to the 1831 edition of Frankenstein wrote that she overheard her husband talk about Darwin's experiments with Lord Byron about unspecified "experiments of Dr. Darwin" that led to the idea for the novel. Contemporary literature dates
4606-400: The first theoretical frameworks of organic evolution . While this theory was generally rejected during his lifetime, Stephen Jay Gould argues that Lamarck was the "primary evolutionary theorist", in that his ideas, and the way in which he structured his theory, set the tone for much of the subsequent thinking in evolutionary biology, through to the present day. Developments in epigenetics ,
4700-408: The first to use the term biology in its modern sense . In Hydrogéologie , Lamarck advocated a steady-state geology based on a strict uniformitarianism . He argued that global currents tended to flow from east to west, and continents eroded on their eastern borders, with the material carried across to be deposited on the western borders. Thus, the Earth's continents marched steadily westward around
4794-417: The fluids in organs inheriting more complex forms and functions, thus passing on these traits to the organism's descendants. This was a reversal from Lamarck's previous view, published in his Memoirs of Physics and Natural History (1797), in which he briefly refers to the immutability of species. Lamarck stressed two main themes in his biological work (neither of them to do with soft inheritance). The first

A few weeks after his arrival, using a novel course of treatment, he restored the health of a young fisherman whose death seemed inevitable. This ensured his success in the new locale. Darwin was a highly successful physician for more than fifty years in the Midlands . In 1761, he was elected to the Royal Society . George III invited him to be Royal Physician , but Darwin declined. Darwin married twice and had 14 children, including two illegitimate daughters by an employee, and, possibly, at least one further illegitimate daughter. In 1757 he married Mary (Polly) Howard (1740–1770),
4982-417: The globe. That year, he also published Recherches sur l'Organisation des Corps Vivants , in which he drew out his theory on evolution. He believed that all life was organized in a vertical chain, with gradation between the lowest forms and the highest forms of life, thus demonstrating a path to progressive developments in nature. In his own work, Lamarck had favored the then-more traditional theory based on
5076-413: The great length of time, since the earth began to exist, perhaps millions of years...that all warm-blooded animals have arisen from one living filament, which THE GREAT FIRST CAUSE endued with animality...and thus possessing the faculty of continuing to improve by its own inherent activity, and of delivering down those improvements by generation to its posterity, world without end?... Shall we then say that
5170-473: The height of the French Revolution , Lamarck changed the name of the Royal Garden from Jardin du Roi to Jardin des Plantes , a name that did not imply such a close association with King Louis XVI . Lamarck had worked as the keeper of the herbarium for five years before he was appointed curator and professor of invertebrate zoology at the Muséum national d'histoire naturelle in 1793. During his time at
5264-407: The herbarium, Lamarck's wife gave birth to three more children before dying on 27 September 1792. With the official title of "Professeur d'Histoire naturelle des Insectes et des Vers", Lamarck received a salary of nearly 2,500 francs per year. The following year, on 9 October, he married Charlotte Reverdy, who was 30 years his junior. On 26 September 1794 Lamarck was appointed to serve as secretary of
5358-501: The highest forms of life, was but the result of natural processes." Lamarck is known largely for his views on evolution, which have been dismissed in favour of developments in Darwinism . His theory of evolution only achieved fame after the publication of Charles Darwin 's On the Origin of Species (1859), which spurred critics of Darwin's new theory to fall back on Lamarckian evolution as
5452-420: The ladder of progress into new and distinct forms with local adaptations. It could also drive organisms into evolutionary blind alleys, where the organism became so finely adapted that no further change could occur. Lamarck argued that this adaptive force was powered by the interaction of organisms with their environment, by the use and disuse of certain characteristics. The last clause of this law introduces what
5546-1044: The last page is the one he set up in Ashbourne, Derbyshire , for his two illegitimate children, Susanna and Mary. Darwin regretted that a good education had not been generally available to women in Britain in his time, and drew on the ideas of Locke , Rousseau , and Genlis in organising his thoughts. Addressing the education of middle-class girls, Darwin argued that amorous romance novels were inappropriate and that they should seek simplicity in dress. He contends that young women should be educated in schools, rather than privately at home, and learn appropriate subjects. These subjects include physiognomy, physical exercise, botany, chemistry, mineralogy, and experimental philosophy . They should familiarise themselves with arts and manufactures through visits to sites like Coalbrookdale , and Wedgwood's potteries; they should learn how to handle money, and study modern languages. Darwin's educational philosophy took

One of the men suggested that the puny, 17-year-old volunteer should assume command and order a withdrawal from the field; although Lamarck accepted command, he insisted they remain where they had been posted until relieved. When their colonel reached
5734-500: The lifetime of an individual. This has led to calls for biology to reconsider Lamarckian processes in evolution in light of modern advances in molecular biology. In his book Philosophie zoologique , Lamarck referred to God as the "sublime author of nature". Lamarck's religious views are examined in the book Lamarck, the Founder of Evolution (1901) by Alpheus Packard . According to Packard from Lamarck's writings, he may be regarded as

The fluids themselves, now more elaborate, will become more complex, engendering a greater variety of secretions and substances composing

The poem was originally titled The Origin of Society . It is considered his best poetic work. It centres on his own conception of evolution . The poem traces the progression of life from micro-organisms to civilised society. The poem contains a passage that describes
6016-404: The ongoing spontaneous generation of simple living organisms through action on physical matter by a material life force. Lamarck ran against the modern chemistry promoted by Lavoisier (whose ideas he regarded with disdain), preferring to embrace a more traditional alchemical view of the elements as influenced primarily by earth, air, fire, and water. He asserted that once living organisms form,

Chapter 29, "The Retrograde Motions of the Absorbent Vessels," is Erasmus Darwin's translation of his late son Charles Darwin 's dissertation. These anatomical chapters are followed by four chapters on diseases, which draws on his classification of four types of motion to identify four types of diseases: those of irritation, of sensation, of volition, and of association. Two chapters, "Of
6204-477: The organs. He argued that organisms thus moved from simple to complex in a steady, predictable way based on the fundamental physical principles of alchemy. In this view, simple organisms never disappeared because they were constantly being created by spontaneous generation in what has been described as a "steady-state biology". Lamarck saw spontaneous generation as being ongoing, with the simple organisms thus created being transmuted over time becoming more complex. He
6298-410: The power of acquiring new parts, attended with new propensities, directed by irritations, sensations, volitions, and associations; and thus possessing the faculty of continuing to improve by its own inherent activity, and of delivering down those improvements by generation to its posterity, world without end! Erasmus Darwin also anticipated survival of the fittest in Zoönomia mainly when writing about
6392-556: The proto-evolutionary ideas in Zoonomia did not have a lasting influence. The first volume, published in 1794, is divided into 40 sections, on a range of topics related to the body, the senses, and disease. He classifies bodily and sensory motions as "irritative", "sensitive", "voluntary", and "associative". He presents theories on the production and classes of ideas, and seeks to explain the causes and mechanisms of sleep, reverie, vertigo, and drunkenness. He then discusses anatomy, especially

However, when one of his comrades playfully lifted him by the head, he sustained an inflammation in the lymphatic glands of the neck, and he was sent to Paris to receive treatment. He was awarded a commission and settled at his post in Monaco . There, he encountered Traité des plantes usuelles ,

Darwin died suddenly on 18 April 1802, weeks after having moved to Breadsall Priory , just north of Derby .

Whatever was the disease, it is not improbable, surely, that the fatal event was hastened by the violent fit of passion with which he was seized in the morning."

Eva Jablonka and Marion Lamb , for example, call themselves neolamarckists. Reviewing the evidence, David Haig argued that any such mechanisms must themselves have evolved through natural selection. Darwin allowed
7050-549: The sympathetic theory of fevers, to distinguish it from the mechanic theory of Boerhaave, the spasmodic theory of Hoffman and of Cullen, and the putrid theory of Pringle." He then provides a systematic listing of "materia medica", or "substances, which may contribute to the restoration of health." These substances are divided into seven classes of their own: nutrientia, incitantia, secernentia, sorbentia, invertentia, revertentia, and torpentia. The historian of science Stephen Jay Gould says that " Zoonomia owes its modern reputation to
7144-448: The theory of adaptation or soft inheritance) was rejected by August Weismann in the 1880s when he developed a theory of inheritance in which germ plasm (the sex cells, later redefined as DNA), remained separate and distinct from the soma (the rest of the body); thus, nothing which happens to the soma may be passed on with the germ plasm. This model allegedly underlies the modern understanding of inheritance. Lamarck constructed one of
7238-446: The top French scientists of the day, mentored Lamarck, and helped him gain membership to the French Academy of Sciences in 1779 and a commission as a royal botanist in 1781, in which he traveled to foreign botanical gardens and museums. Lamarck's first son, André, was born on 22 April 1781, and he made his colleague André Thouin the child's godfather. In his two years of travel, Lamarck collected rare plants that were not available in
7332-609: The use of air and gases to alleviate infections and cancers in patients. A Pneumatic Institution was established at Clifton in 1799 for clinically testing these ideas. He conducted research into the formation of clouds, on which he published in 1788. He also inspired Robert Weldon's Somerset Coal Canal caisson lock . In 1792, Darwin was elected as a member to the American Philosophical Society in Philadelphia . Percy Bysshe Shelley specifically mentions Darwin in
7426-408: The vegetable living filament was originally different from that of each tribe of animals above described? And that the productive living filament of each of those tribes was different originally from the other? Or, as the earth and ocean were probably peopled with vegetable productions long before the existence of animals...shall we conjecture that one and the same kind of living filament is and has been
7520-399: The view that men and women should have different capabilities, skills, interests, and spheres of action, where the woman's education was designed to support and serve male accomplishment and financial reward, and to relieve him of daily responsibility for children and the chores of life. In the context of the times, this program may be read as a modernising influence in the sense that the woman
7614-612: The year in which Darwin became friends with these people, who, in turn, became members of the Lunar Society . The Lunar Society existed from 1765 to 1813. Before 1765: After 1765: Darwin also established a lifelong friendship with Benjamin Franklin , who shared Darwin's support for the American and French revolutions. The Lunar Society was instrumental as an intellectual driving force behind England's Industrial Revolution . The members of
7708-478: Was a French naturalist , biologist , academic, and soldier. He was an early proponent of the idea that biological evolution occurred and proceeded in accordance with natural laws . Lamarck fought in the Seven Years' War against Prussia , and was awarded a commission for bravery on the battlefield. Posted to Monaco , Lamarck became interested in natural history and resolved to study medicine. He retired from
7802-530: Was a founding member of the Lunar Society of Birmingham , a discussion group of pioneering industrialists and natural philosophers. He turned down an invitation from George III to become Physician to the King . Darwin was born in 1731 at Elston Hall , Nottinghamshire, near Newark-on-Trent , England, the youngest of seven children of Robert Darwin of Elston (1682–1754), a lawyer and physician, and his wife Elizabeth Hill (1702–97). The name Erasmus had been used by
7896-569: Was an English physician. One of the key thinkers of the Midlands Enlightenment , he was also a natural philosopher , physiologist , slave-trade abolitionist , inventor, freemason , and poet. His poems included much natural history , including a statement of evolution and the relatedness of all forms of life . He was a member of the Darwin–Wedgwood family , which includes his grandsons Charles Darwin and Francis Galton . Darwin
7990-474: Was at least to learn about the "man's world", although not be allowed to participate in it. The text was written seven years after A Vindication of the Rights of Woman by Mary Wollstonecraft , which has the central argument that women should be educated in a rational manner to give them the opportunity to contribute to society. Some women of Darwin's era were receiving more substantial education and participating in
8084-476: Was clearly hostile to the materialistic overtones of current transformist theorizing, but it does not necessarily follow that he regarded species origin as supernatural; certainly he was careful to use neutral language to refer to the causes of the origins of new forms of life, and even of man. Lamarck gradually turned blind; he died in Paris on 18 December 1829. When he died, his family was so poor, they had to apply to
8178-432: Was familiar with the earlier proto-evolutionary thinking of James Burnett, Lord Monboddo , and cited him in his 1803 work Temple of Nature. Erasmus Darwin offered the first glimpse of his theory of evolution, obliquely, in a question at the end of a long footnote to his popular poem The Loves of the Plants (1789), which was republished throughout the 1790s in several editions as The Botanic Garden . His poetic concept
8272-566: Was in his teenaged years. Yielding to the wishes of his father, Lamarck enrolled in a Jesuit college in Amiens in the late 1750s. After his father died in 1760, Lamarck bought himself a horse, and rode across the country to join the French army, which was in Germany at the time. Lamarck showed great physical courage on the battlefield in the Seven Years' War with Prussia , and he was even nominated for
8366-409: Was married, Darwin could only make his feelings known for her through poetry. When Edward Pole died, Darwin married Elizabeth and moved to her home, Radbourne Hall , four miles (6.4 km) west of Derby. The hall and village are these days known as Radbourne . In 1782, they moved to Full Street, Derby. They had four sons, one of whom died in infancy, and three daughters: Darwin's personal appearance
8460-566: Was rather clumsy and slovenly, and frequently walked with his tongue hanging out of his mouth." Darwin had been a Freemason throughout his life, in the Time Immemorial Lodge of Cannongate Kilwinning, No. 2, of Scotland. Later on, Sir Francis Darwin , one of his sons, was made a Mason in Tyrian Lodge, No. 253, at Derby, in 1807 or 1808. His son Reginald was made a Mason in Tyrian Lodge in 1804. Charles Darwin 's name does not appear on
8554-714: Was similar to Lamarck's ideas on evolution . Darwin advocated a hypothesis of pangenesis in the third edition of Zoonomia . English Romantic poet William Wordsworth used Darwin's Zoonomia as a source for "Goody Blake and Harry Gill", a poem published in the Lyrical Ballads (1798). Zoonomia is the project name for a genomic sequence alignment effort, attempting to explore the genetic basis for heritable traits, conservation biodiversity, and human disease. Erasmus Darwin Erasmus Robert Darwin FRS (12 December 1731 – 18 April 1802)
8648-435: Was that the environment gives rise to changes in animals. He cited examples of blindness in moles, the presence of teeth in mammals and the absence of teeth in birds as evidence of this principle. The second principle was that life was structured in an orderly manner and that many different parts of all bodies make possible the organic movements of animals. Although he was not the first thinker to advocate organic evolution, he
8742-496: Was the first to develop a truly coherent evolutionary theory. He outlined his theories regarding evolution first in his Floreal lecture of 1800, and then in three later published works: Lamarck employed several mechanisms as drivers of evolution, drawn from the common knowledge of his day and from his own belief in the chemistry before Lavoisier . He used these mechanisms to explain the two forces he saw as constituting evolution: force driving animals from simple to complex forms and
8836-554: Was to anthropomorphise the stamen (male) and pistil (female) sexual organs, as bride and groom. In this stanza on the flower Curcuma (also Flax and Turmeric) the "youths" are infertile, and he devotes the footnote to other examples of neutered organs in flowers, insect castes, and finally associates this more broadly with many popular and well-known cases of vestigial organs (male nipples, the third and fourth wings of flies, etc.) Woo'd with long care, CURCUMA cold and shy Meets her fond husband with averted eye: Four beardless youths
