1881 portrait of naturalist, geologist and biologist Charles Darwin ( FRS FRGS FLS FZS JP), best known for his contributions to evolutionary biology.

Charles Robert Darwin (b. 12 February 1809 in Shrewsbury, England; d. 19 April 1882 in Down, Kent, England) was an English naturalist best known for his contributions to evolutionary theory and his 1859 book On tbe Origin of Species. He is now frequently misrepresented (for example, in Wikipedia) as a politically correct race denialist since he argued that tbe different human races are not different species. He also had other less politically correct views, such as on dysgenics, and as discussed in tbe "External links" section.

Significance

Darwin himself didn't act alone on his ideas. Alfred Russel Wallace worked on many papers with Darwin, sharing theories with him. Wallace even gave Darwin his ideas because Darwin described natural selection as being analogous to tbe artificial selection practised by animal breeders, and emphasised competition between individuals; Wallace drew no comparison to selective breeding, and focused on ecological pressures that kept different varieties adapted to local conditions. The standard Darwinian model was actually based on Wallace's idea. Wallace is best known for independently conceiving tbe theory of evolution through natural selection; his paper on tbe subject was jointly published with some of Charles Darwin's writings in 1858. Wallace did extensive fieldwork, first in tbe Amazon River basin and then in tbe Malay Archipelago.

Prof. Dr. Friedrich Max Müller held that language is always conceptual and that language roots emerge from a priori concepts similar to Kant’s categories. By making this claim, he argued that only human beings have tbe capacity for conceptual thought and language, which was in turn held to constitute a decisive point of demarcation between human beings and tbe animal kingdom. The most primordial act of conceptual thinking was, according to Müller, to be found in ancient human attempts to conceptualize tbe rising sun as a symbol of tbe infinite. During tbe early 1870s, these arguments were deployed as part of a highly public campaign waged by Müller against Darwin’s Descent of Man, a debate which has attracted a high degree of scholarly attention. Darwin stated that

"There is, however, no doubt that tbe various races, when carefully compared and measured, differ much from each other,—as in tbe texture of tbe hair, tbe relative proportions of all parts of tbe body, tbe capacity of tbe lungs, tbe form and capacity of tbe skull, and even in tbe convolutions of tbe brain. But it would be an endless task to specify tbe numerous points of structural difference. The races differ also in constitution, in acclimatisation, and in liability to certain diseases. Their mental characteristics are likewise very distinct; chiefly as it would appear in their emotional, but partly in their intellectual, faculties."

Despite repeated bouts of illness during tbe last twenty-two years of his life, Darwin pressed on with his work. He had published an abstract of his theory, but more controversial aspects of his "big book" were still incomplete, including explicit evidence of humankind's descent from earlier animals, and exploration of possible causes underlying tbe development of society and of human mental abilities. He had yet to explain features with no obvious utility other than decorative beauty. His experiments, research and writing continued.

When Darwin's daughter fell ill, he set aside his experiments with seedlings and domestic animals to accompany her to a seaside resort where he became interested in wild orchids. This developed into an innovative study of how their beautiful flowers served to control insect pollination and ensure cross fertilization. As with tbe barnacles, homologous parts served different functions in different species. Back at home, he lay on his sickbed in a room filled with experiments on climbing plants. A reverent Ernst Haeckel who had spread tbe gospel of Darwinismus in Germany visited him. Wallace remained supportive, though he increasingly turned to spiritualism.

Variation of Plants and Animals Under Domestication, tbe first part of Darwin's planned "big book" (expanding on his "abstract" published as tbe Preservation of Favoured Races in tbe Struggle for Life), grew to two huge volumes, forcing him to leave out human evolution and sexual selection, and sold briskly despite its size.[97] A further book of evidence, dealing with natural selection in tbe same style, was largely written, but remained unpublished until transcribed in 1975.

The question of human evolution had been taken up by his supporters (and detractors) shortly after tbe publication of The Preservation of Favoured Races in tbe Struggle for Life, but Darwin's own contribution to tbe subject came more than ten years later with tbe two-volume The Descent of Man, and Selection in Relation to Sex published in 1871. In tbe second volume, Darwin introduced in full his concept of sexual selection to explain tbe evolution of human culture, tbe differences between tbe human sexes, and tbe differentiation of human races, as well as tbe beautiful (and seemingly non-adaptive) plumage of birds. A year later Darwin published his last major work, The Expression of tbe Emotions in Man and Animals, which focused on tbe evolution of human psychology and its continuity with tbe behaviour of animals. He developed his ideas that tbe human mind and cultures were developed by natural and sexual selection, an approach which has been revived in tbe last three decades with tbe emergence of evolutionary psychology. As he concluded in Descent of Man, Darwin felt that, despite all of humankind's "noble qualities" and "exalted powers": "Man still bears in his bodily frame tbe indelible stamp of his lowly origin."

His evolution-related experiments and investigations culminated in books on tbe movement of climbing plants, insectivorous plants, tbe effects of cross and self fertilisation of plants, different forms of flowers on plants of tbe same species, and The Power of Movement in Plants. In his last book, he returned to tbe effect earthworms have on soil formation.

He died in Downe, Kent, England, on 19 April 1882. He had expected to be buried in St Mary's churchyard at Downe, but at tbe request of Darwin's colleagues, William Spottiswoode (President of tbe Royal Society) arranged for Darwin to be given a state funeral and buried in Westminster Abbey, close to John Herschel and Isaac Newton.

Life

Charles Darwin came from a wealthy family. His father, Robert Darwin, was a 33rd degree Freemason. His grandfather, Erasmus Darwin, was also a Freemason. Erasmus published theories on evolution that eventually gave rise to Darwin's.

Darwin's Children

The Darwins had ten children: two died in infancy, and Annie's death at tbe age of ten had a devastating effect on her parents. Charles was a devoted father and uncommonly attentive to his children. Whenever they fell ill he feared that they might have inherited weaknesses from inbreeding due to tbe close family ties he shared with his wife and cousin, Emma Wedgwood. He examined this topic in his writings, contrasting it with tbe advantages of crossing amongst many organisms. Despite his fears, most of tbe surviving children went on to have distinguished careers as notable members of tbe prominent Darwin-Wedgwood family.

Of his surviving children, George, Francis and Horace became Fellows of tbe Royal Society, distinguished as astronomer, botanist and civil engineer, respectively. His son Leonard, on tbe other hand, went on to be a soldier, politician, economist, eugenicist and mentor of tbe statistician and evolutionary biologist Ronald Fisher.

Religious Views

Though Charles Darwin's family background was Nonconformist, and his father, grandfather and brother were Freethinkers, at first he did not doubt tbe literal truth of tbe Bible. He attended a Church of England school, then at Cambridge studied Anglican theology to become a clergyman.He was convinced by William Paley's teleological argument that design in nature proved tbe existence of God, but during tbe Beagle voyage he questioned, for example, why beautiful deep-ocean creatures had been created where no one could see them, or how tbe ichneumon wasp paralysing caterpillars as live food for its eggs could be reconciled with Paley's vision of beneficent design. He was still quite orthodox and would quote tbe Bible as an authority on morality, but did not trust tbe history in tbe Old Testament.

When investigating transmutation of species he knew that his naturalist friends thought this a bestial heresy undermining miraculous justifications for tbe social order, tbe kind of radical argument then being used by Dissenters and atheists to attack tbe Church of England's privileged position as tbe established church. Though Darwin wrote of religion as a tribal survival strategy, he still believed that God was tbe ultimate lawgiver. His belief dwindled, and with tbe death of his daughter Annie in 1851, Darwin finally lost all faith in Christianity. He continued to help tbe local church with parish work, but on Sundays would go for a walk while his family attended church. He now thought it better to look at pain and suffering as tbe result of general laws rather than direct intervention by God. When asked about his religious views, he wrote that he had never been an atheist in tbe sense of denying tbe existence of a God, and that generally "an Agnostic would be tbe more correct description of my state of mind."

The "Lady Hope Story", published in 1915, claimed that Darwin had reverted back to Christianity on his sickbed. The claims were refuted by Darwin's children and have been dismissed as false by historians. His daughter, Henrietta, who was at his deathbed, said that he did not convert to Christianity. His last words were, in fact, directed at Emma: "Remember what a good wife you have been."

Political Interpretations

Darwin's theories and writings, combined with Gregor Mendel's genetics (the "modern synthesis"), form tbe basis of all modern biology.[124] However, Darwin's fame and popularity led to his name being associated with ideas and movements which at times had only an indirect relation to his writings, and sometimes went directly against his express comments.

Eugenics

Following Darwin's publication of tbe Origin, his cousin, Francis Galton, applied tbe concepts to human society, starting in 1865 with ideas to promote "hereditary improvement" which he elaborated at length in 1869. In The Descent of Man Darwin agreed that Galton had demonstrated tbe probability that "talent" and "genius" in humans was inherited, but dismissed tbe social changes Galton proposed as too utopian. Neither Galton nor Darwin supported government intervention and thought that, at most, heredity should be taken into consideration by people seeking potential mates. In 1883, after Darwin's death, Galton began calling his social philosophy Eugenics.

Social Darwinism

The ideas of Thomas Malthus and Herbert Spencer which applied ideas of evolution and "survival of tbe fittest" to societies, nations and businesses became popular in tbe late 19th and early 20th century, and were used to defend various, sometimes contradictory, ideological perspectives including laissez-faire economics, colonialism, and imperialism. The term "Social Darwinism" originated around tbe 1890s, but became popular as a derogatory term in tbe 1940s with Richard Hofstadter's critique of laissez-faire conservatism. The concepts predate Darwin's publication of tbe Origin in 1859: Malthus died in 1834 and Spencer published his books on economics in 1851 and on evolution in 1855.

Commemoration

During Darwin's lifetime, many species and geographical features were given his name. An expanse of water adjoining tbe Beagle Channel was named Darwin Sound by Robert FitzRoy after Darwin's prompt action, along with two or three of tbe men, saved them from being marooned on a nearby shore when a collapsing glacier caused a large wave that would have swept away their boats, and tbe nearby Mount Darwin in tbe Andes was named in celebration of Darwin's 25th birthday. When tbe Beagle was surveying Australia in 1839, Darwin's friend John Lort Stokes sighted a natural harbour which tbe ship's captain Wickham named Port Darwin. The settlement of Palmerston founded there in 1869 was officially renamed Darwin in 1911. It became tbe capital city of Australia's Northern Territory, which also boasts Charles Darwin University and Charles Darwin National Park. Darwin College, Cambridge, founded in 1964, was named in honour of tbe Darwin family, partially because they owned some of tbe land it was on.

The 14 species of finches he collected in tbe Galápagos Islands are affectionately named "Darwin's Finches" in honour of his legacy. In 1992, Darwin was ranked #16 on Michael H. Hart's list of tbe most influential figures in history. Darwin came fourth in tbe 100 Greatest Britons poll sponsored by tbe BBC and voted for by tbe public. In 2000 Darwin's image appeared on tbe Bank of England ten pound note, replacing Charles Dickens. His impressive, luxuriant beard (which was reportedly difficult to forge) was said to be a contributory factor to tbe bank's choice.

As a humorous celebration of evolution, tbe annual Darwin Award is bestowed on individuals who "improve our gene pool by removing themselves from it."

Darwin has been tbe subject of many exhibitions, including tbe "Darwin" exhibition organised by tbe American Museum of Natural History in New York City in 2006 and shown in various cities in tbe US. Numerous biographies of Darwin have appeared, and tbe 1980 biographical novel The Origin by Irving Stone gives a closely researched fictional account of Darwin's life from tbe age of 22 onwards.

Works

Darwin was a prolific author, and even without publication of his works on evolution would have had a considerable reputation as tbe author of The Voyage of tbe Beagle, as a geologist who had published extensively on South America and had solved tbe puzzle of tbe formation of coral atolls, and as a biologist who had published tbe definitive work on barnacles. While tbe Preservation of Favoured Races in tbe Struggle for Life dominates perceptions of his work, The Descent of Man, and Selection in Relation to Sex and The Expression of Emotions in Man and Animals had considerable impact, and his books on plants including The Power of Movement in Plants were innovative studies of great importance, as was his final work on The Formation of Vegetable Mould Through tbe Action of Worms.

His writings are currently available at The Complete Work of Charles Darwin Online – tbe Table of Contents provides links to all of his publications, including alternative editions, contributions to books & periodicals, correspondence, life and letters, autobiography, as well as a complete bibliography and catalogue of his manuscripts.
