An organism is defined in a medical dictionary as any living thing that functions as an individual . Such a definition raises more problems than it solves, not least because the concept of an individual is also difficult. Many criteria, few of them widely accepted, have been proposed to define what an organism is. Among the most common is that an organism has autonomous reproduction , growth , and metabolism . This would exclude viruses , despite the fact that they evolve like organisms. Other problematic cases include colonial organisms ; a colony of eusocial insects is organised adaptively, and has germ-soma specialisation , with some insects reproducing, others not, like cells in an animal's body. The body of a siphonophore , a jelly-like marine animal, is composed of organism-like zooids , but the whole structure looks and functions much like an animal such as a jellyfish , the parts collaborating to provide the functions of the colonial organism.
54-518: Dinosaur State Park and Arboretum is a state-owned natural history preserve occupying 80 acres (32 ha) in the town of Rocky Hill, Connecticut . The state park protects one of the largest dinosaur track sites in North America . The park was created in recognition of fossil trackways embedded in sandstone from the beginning of the Jurassic period , about 200 million years ago. The facility
108-569: A few enzymes and molecules like those in living organisms, they have no metabolism of their own; they cannot synthesize the organic compounds from which they are formed. In this sense, they are similar to inanimate matter. Viruses have their own genes , and they evolve . Thus, an argument that viruses should be classed as living organisms is their ability to undergo evolution and replicate through self-assembly. However, some scientists argue that viruses neither evolve nor self-reproduce. Instead, viruses are evolved by their host cells, meaning that there
162-476: A naturalist, studies the world by observing plants and animals directly. Because organisms are functionally inseparable from the environment in which they live and because their structure and function cannot be adequately interpreted without knowing some of their evolutionary history, the study of natural history embraces the study of fossils as well as physiographic and other aspects of the physical environment". A common thread in many definitions of natural history
216-544: A part of science proper. In Victorian Scotland, the study of natural history was believed to contribute to good mental health. Particularly in Britain and the United States, this grew into specialist hobbies such as the study of birds , butterflies, seashells ( malacology / conchology ), beetles, and wildflowers; meanwhile, scientists tried to define a unified discipline of biology (though with only partial success, at least until
270-470: A type of observation and a subject of study, it can also be defined as a body of knowledge, and as a craft or a practice, in which the emphasis is placed more on the observer than on the observed. Definitions from biologists often focus on the scientific study of individual organisms in their environment, as seen in this definition by Marston Bates: "Natural history is the study of animals and Plants—of organisms. ... I like to think, then, of natural history as
324-598: Is a cross-discipline umbrella of many specialty sciences; e.g., geobiology has a strong multidisciplinary nature. The meaning of the English term "natural history" (a calque of the Latin historia naturalis ) has narrowed progressively with time, while, by contrast, the meaning of the related term "nature" has widened (see also History below). In antiquity , "natural history" covered essentially anything connected with nature , or used materials drawn from nature, such as Pliny
378-445: Is a microorganism such as a protist , bacterium , or archaean , composed of a single cell , which may contain functional structures called organelles . A multicellular organism such as an animal , plant , fungus , or alga is composed of many cells, often specialised. A colonial organism such as a siphonophore is a being which functions as an individual but is composed of communicating individuals. A superorganism
432-401: Is a teleonomic or goal-seeking behaviour that enables them to correct errors of many kinds so as to achieve whatever result they are designed for. Such behaviour is reminiscent of intelligent action by organisms; intelligence is seen as an embodied form of cognition . All organisms that exist today possess a self-replicating informational molecule (genome), and such an informational molecule
486-741: Is a colony, such as of ants , consisting of many individuals working together as a single functional or social unit . A mutualism is a partnership of two or more species which each provide some of the needs of the other. A lichen consists of fungi and algae or cyanobacteria , with a bacterial microbiome ; together, they are able to flourish as a kind of organism, the components having different functions, in habitats such as dry rocks where neither could grow alone. The evolutionary biologists David Queller and Joan Strassmann state that "organismality" has evolved socially, as groups of simpler units (from cells upwards) came to cooperate without conflicts. They propose that cooperation should be used as
540-567: Is a stone path that leads to the domed museum with a timeline showing the evolution of earth from its creation to today. From May to October, visitors can see an outdoor exhibit teaching how paleontologists ply their trade. There are two and a half miles of hiking trails in the park. Natural history Natural history is a domain of inquiry involving organisms , including animals , fungi , and plants , in their natural environment , leaning more towards observational than experimental methods of study. A person who studies natural history
594-460: Is also echoed by H.W. Greene and J.B. Losos: "Natural history focuses on where organisms are and what they do in their environment, including interactions with other organisms. It encompasses changes in internal states insofar as they pertain to what organisms do". Some definitions go further, focusing on direct observation of organisms in their environments, both past and present, such as this one by G.A. Bartholomew: "A student of natural history, or

#1732855299313648-535: Is an argument for viewing viruses as cellular organisms. Some researchers perceive viruses not as virions alone, which they believe are just spores of an organism, but as a virocell - an ontologically mature viral organism that has cellular structure. Such virus is a result of infection of a cell and shows all major physiological properties of other organisms: metabolism , growth, and reproduction , therefore, life in its effective presence. The philosopher Jack A. Wilson examines some boundary cases to demonstrate that
702-411: Is called a naturalist or natural historian . Natural history encompasses scientific research but is not limited to it. It involves the systematic study of any category of natural objects or organisms, so while it dates from studies in the ancient Greco-Roman world and the mediaeval Arabic world , through to European Renaissance naturalists working in near isolation, today's natural history
756-472: Is likely intrinsic to life. Thus, the earliest organisms also presumably possessed a self-replicating informational molecule ( genome ), perhaps RNA or an informational molecule more primitive than RNA. The specific nucleotide sequences in all currently extant organisms contain information that functions to promote survival, reproduction , and the ability to acquire resources necessary for reproduction, and sequences with such functions probably emerged early in
810-579: Is managed by the Connecticut Department of Energy and Environmental Protection . The Rocky Hill dinosaur tracks were uncovered in 1966, adding to the extensive legacy of fossil discoveries made in the Connecticut Valley since the 19th century. A bulldozer operator noticed the tracks while excavating the site for a new state office building. The site opened as Dinosaur State Park in 1968, the same year its 7-acre (2.8 ha) dinosaur trackway
864-399: Is the inclusion of a descriptive component, as seen in a recent definition by H.W. Greene: "Descriptive ecology and ethology". Several authors have argued for a more expansive view of natural history, including S. Herman, who defines the field as "the scientific study of plants and animals in their natural environments. It is concerned with levels of organization from the individual organism to
918-538: The American Society of Naturalists and Polish Copernicus Society of Naturalists . Professional societies have recognized the importance of natural history and have initiated new sections in their journals specifically for natural history observations to support the discipline. These include "Natural History Field Notes" of Biotropica , "The Scientific Naturalist" of Ecology , "From the Field" of Waterbirds , and
972-486: The Ancient Greek ὀργανισμός , derived from órganon , meaning instrument, implement, tool, organ of sense or apprehension) first appeared in the English language in the 1660s with the now-obsolete meaning of an organic structure or organization. It is related to the verb "organize". In his 1790 Critique of Judgment , Immanuel Kant defined an organism as "both an organized and a self-organizing being". Among
1026-468: The Industrial Revolution prompted the development of geology to help find useful mineral deposits. Modern definitions of natural history come from a variety of fields and sources, and many of the modern definitions emphasize a particular aspect of the field, creating a plurality of definitions with a number of common themes among them. For example, while natural history is most often defined as
1080-476: The Natural History Society of Northumbria founded in 1829, London Natural History Society (1858), Birmingham Natural History Society (1859), British Entomological and Natural History Society founded in 1872, Glasgow Natural History Society, Manchester Microscopical and Natural History Society established in 1880, Whitby Naturalists' Club founded in 1913, Scarborough Field Naturalists' Society and
1134-459: The Renaissance , and quickly became a third branch of academic knowledge, itself divided into descriptive natural history and natural philosophy , the analytical study of nature. In modern terms, natural philosophy roughly corresponded to modern physics and chemistry , while natural history included the biological and geological sciences. The two were strongly associated. During the heyday of

#17328552993131188-472: The Renaissance , making it one of the longest-lasting of all natural history books. From the ancient Greeks until the work of Carl Linnaeus and other 18th-century naturalists, a major concept of natural history was the scala naturae or Great Chain of Being , an arrangement of minerals, vegetables, more primitive forms of animals, and more complex life forms on a linear scale of supposedly increasing perfection, culminating in our species. Natural history
1242-758: The Triassic and Jurassic periods. Other exhibits include interactive displays; a reconstruction of a geologic foundation; and a historical exhibit depicting highlights of the unearthing of the tracks in 1966. The discovery room houses a blue-tongued skink , ball python , and dinosaur-related arts and crafts. Rock slabs with other Connecticut Valley fossil tracks, including large four-toed Otozoum tracks with visible skin impressions, can also be seen. The arboretum's 2 miles (3.2 km) of trails pass through some 250 species and cultivars of conifers, plus collections of arborvitae , chamaecyparis , ginkgo , juniper , katsura , pine , sequoia , and magnolia . Rarer species in

Still, the traditions of natural history continue to play a part in the study of biology, especially ecology (the study of natural systems involving living organisms and the inorganic components of the Earth's biosphere that support them), ethology (the scientific study of animal behavior), and evolutionary biology (the study of the relationships between life forms over very long periods of time), and re-emerges today as integrative organismal biology. Amateur collectors and natural history entrepreneurs played an important role in building
1404-636: The "Natural History Miscellany section" of the American Naturalist . Natural history observations have contributed to scientific questioning and theory formation. In recent times such observations contribute to how conservation priorities are determined. Mental health benefits can ensue, as well, from regular and active observation of chosen components of nature, and these reach beyond the benefits derived from passively walking through natural areas. Organism The evolutionary biologists David Queller and Joan Strassmann state that "organismality",
1458-642: The "defining trait" of an organism. Samuel Díaz‐Muñoz and colleagues (2016) accept Queller and Strassmann's view that organismality can be measured wholly by degrees of cooperation and of conflict. They state that this situates organisms in evolutionary time, so that organismality is context dependent. They suggest that highly integrated life forms, which are not context dependent, may evolve through context-dependent stages towards complete unification. Viruses are not typically considered to be organisms, because they are incapable of autonomous reproduction , growth , metabolism , or homeostasis . Although viruses have
1512-533: The Elder 's encyclopedia of this title , published c. 77 to 79 AD , which covers astronomy , geography , humans and their technology , medicine , and superstition , as well as animals and plants. Medieval European academics considered knowledge to have two main divisions: the humanities (primarily what is now known as classics ) and divinity , with science studied largely through texts rather than observation or experiment. The study of nature revived in

In the evolutionary past of our species, the practice of natural history was essential for our survival, imparting critical information on habits and chronologies of plants and animals that we could eat or that could eat us. Natural history continues to be critical to human survival and thriving. It contributes to our fundamental understanding of how
1620-539: The Sorby Natural History Society, Sheffield , founded in 1918. The growth of natural history societies was also spurred due to the growth of British colonies in tropical regions with numerous new species to be discovered. Many civil servants took an interest in their new surroundings, sending specimens back to museums in the Britain . (See also: Indian natural history ) Societies in other countries include

The addition of woody plants from Cretaceous angiosperm families has been part of the arboretum's attempt to grow as many representatives of Mesozoic -era plant families as the site's New England climate will allow. The park offers educational films, guided trail walks, and lectures. Warm-month activities include footprint track casting and mining for gems and fossils. In August, Dinosaur State Park Day offers games, arts and crafts activities, and live music. There

1728-678: The concept of organism is not sharply defined. In his view, sponges , lichens , siphonophores , slime moulds , and eusocial colonies such as those of ants or naked molerats , all lie in the boundary zone between being definite colonies and definite organisms (or superorganisms). Scientists and bio-engineers are experimenting with different types of synthetic organism , from chimaeras composed of cells from two or more species, cyborgs including electromechanical limbs, hybrots containing both electronic and biological elements, and other combinations of systems that have variously evolved and been designed. An evolved organism takes its form by
1782-476: The criteria that have been proposed for being an organism are: Other scientists think that the concept of the organism is inadequate in biology; that the concept of individuality is problematic; and from a philosophical point of view, question whether such a definition is necessary. Problematic cases include colonial organisms : for instance, a colony of eusocial insects fulfills criteria such as adaptive organisation and germ-soma specialisation. If so,
1836-403: The diversity of the natural world. Natural history was understood by Pliny the Elder to cover anything that could be found in the world, including living things, geology, astronomy, technology, art, and humanity. De Materia Medica was written between 50 and 70 AD by Pedanius Dioscorides , a Roman physician of Greek origin. It was widely read for more than 1,500 years until supplanted in
1890-410: The ecosystem, and stresses identification, life history, distribution, abundance, and inter-relationships. It often and appropriately includes an esthetic component", and T. Fleischner, who defines the field even more broadly, as "A practice of intentional, focused attentiveness and receptivity to the more-than-human world, guided by honesty and accuracy". These definitions explicitly include the arts in
1944-710: The emergence of professional biological disciplines and research programs. Particularly in the 19th century, scientists began to use their natural history collections as teaching tools for advanced students and the basis for their own morphological research. The term "natural history" alone, or sometimes together with archaeology, forms the name of many national, regional, and local natural history societies that maintain records for animals (including birds (ornithology), insects ( entomology ) and mammals (mammalogy)), fungi ( mycology ), plants (botany), and other organisms. They may also have geological and microscopical sections. Examples of these societies in Britain include
1998-422: The evolution of life. It is also likely that survival sequences present early in the evolution of organisms included sequences that facilitate the avoidance of damage to the self-replicating molecule and promote the capability to repair such damages that do occur. Repair of some of the genome damages in these early organisms may have involved the capacity to use undamaged information from another similar genome by
2052-411: The field of botany, be it as authors, collectors, or illustrators. In modern Europe, professional disciplines such as botany, geology, mycology , palaeontology , physiology , and zoology were formed. Natural history , formerly the main subject taught by college science professors, was increasingly scorned by scientists of a more specialized manner and relegated to an "amateur" activity, rather than

Lopez, who defines the field as the "Patient interrogation of a landscape" while referring to the natural history knowledge of the Eskimo ( Inuit ). A slightly different framework for natural history, covering a similar range of themes, is also implied in the scope of work encompassed by many leading natural history museums , which often include elements of anthropology, geology, paleontology, and astronomy along with botany and zoology, or include both cultural and natural components of

The Eubrontes tracks range from 10 to 16 inches (410 mm) in length and are spaced 3.5 to 4.5 feet (1.4 m) apart. In addition to the tracks, the dome houses life-sized dioramas of plants and creatures, including Dilophosaurus , from depict

The existence of chimaeras and hybrids demonstrates that these mechanisms are "intelligently" robust in the face of radically altered circumstances at all levels from molecular to organismal. Synthetic organisms already take diverse forms, and their diversity will increase. What they all have in common

2268-480: The qualities or attributes that define an entity as an organism, has evolved socially as groups of simpler units (from cells upwards) came to cooperate without conflicts. They propose that cooperation should be used as the "defining trait" of an organism. This would treat many types of collaboration, including the fungus / alga partnership of different species in a lichen , or the permanent sexual partnership of an anglerfish , as an organism. The term "organism" (from
2322-612: The same argument, or a criterion of high co-operation and low conflict, would include some mutualistic (e.g. lichens) and sexual partnerships (e.g. anglerfish ) as organisms. If group selection occurs, then a group could be viewed as a superorganism , optimized by group adaptation . Another view is that attributes like autonomy, genetic homogeneity and genetic uniqueness should be examined separately rather than demanding that an organism should have all of them; if so, there are multiple dimensions to biological individuality, resulting in several types of organism. A unicellular organism

The British historian of Chinese science Joseph Needham calls Li Shizhen "the 'uncrowned king' of Chinese naturalists", and his Bencao gangmu "undoubtedly the greatest scientific achievement of the Ming". His works translated to many languages direct or influence many scholars and researchers. A significant contribution to English natural history

It also serves as the basis for all conservation efforts, with natural history both informing the science and inspiring the values that drive these. As a precursor to Western science , natural history began with Aristotle and other ancient philosophers who analyzed

Three of the greatest English naturalists of the 19th century, Henry Walter Bates , Charles Darwin , and Alfred Russel Wallace —who knew each other—each made natural history travels that took years, collected thousands of specimens, many of them new to science, and by their writings both advanced knowledge of "remote" parts of

The plurality of definitions for this field has been recognized as both a weakness and a strength, and a range of definitions has recently been offered by practitioners in a recent collection of views on natural history. Prior to the advent of Western science humans were engaged and highly competent in indigenous ways of understanding the more-than-human world that are now referred to as traditional ecological knowledge . 21st century definitions of natural history are inclusive of this understanding, such as this by Thomas Fleischner of

The understanding of "Nature" as "an organism and not as a mechanism" can be traced to the writings of Alexander von Humboldt (Prussia, 1769–1859). Humboldt's copious writings and research were seminal influences for Charles Darwin, Simón Bolívar , Henry David Thoreau , Ernst Haeckel , and John Muir . Natural history museums , which evolved from cabinets of curiosities , played an important role in

From the 13th century, the work of Aristotle was adapted rather rigidly into Christian philosophy , particularly by Thomas Aquinas , forming the basis for natural theology . During the Renaissance, scholars (herbalists and humanists, particularly) returned to direct observation of plants and animals for natural history, and many began to accumulate large collections of exotic specimens and unusual monsters . Leonhart Fuchs

The discovery of viruses with genes coding for energy metabolism and protein synthesis fuelled the debate about whether viruses are living organisms, but the genes have a cellular origin. Most likely, they were acquired through horizontal gene transfer from viral hosts. There
