Alexander Darwin Biography & Facts

Charles Robert Darwin ( DAR-win; 12 February 1809 – 19 April 1882) was an English naturalist, geologist and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. His studies at the University of Cambridge's Christ's College from 1828 to 1831 encouraged his passion for natural science. His five-year voyage on HMS Beagle from 1831 to 1836 established Darwin as an eminent geologist, whose observations and theories supported Charles Lyell's concept of gradual geological change. Publication of his journal of the voyage made Darwin famous as a popular author. Puzzled by the geographical distribution of wildlife and fossils he collected on the voyage, Darwin began detailed investigations and, in 1838, devised his theory of natural selection. Although he discussed his ideas with several naturalists, he needed time for extensive research, and his geological work had priority. He was writing up his theory in 1858 when Alfred Russel Wallace sent him an essay that described the same idea, prompting immediate joint submission of both their theories to the Linnean Society of London. Darwin's work established evolutionary descent with modification as the dominant scientific explanation of diversification in nature. In 1871, he examined human evolution and sexual selection in The Descent of Man, and Selection in Relation to Sex, followed by The Expression of the Emotions in Man and Animals (1872). His research on plants was published in a series of books, and in his final book, The Formation of Vegetable Mould, through the Actions of Worms (1881), he examined earthworms and their effect on soil. Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species. By the 1870s, the scientific community and a majority of the educated public had accepted evolution as a fact. However, many favoured competing explanations that gave only a minor role to natural selection, and it was not until the emergence of the modern evolutionary synthesis from the 1930s to the 1950s that a broad consensus developed in which natural selection was the basic mechanism of evolution. Darwin's scientific discovery is the unifying theory of the life sciences, explaining the diversity of life. Biography Early life and education Darwin was born in Shrewsbury, Shropshire, on 12 February 1809, at his family's home, The Mount. He was the fifth of six children of wealthy society doctor and financier Robert Darwin and Susannah Darwin (née Wedgwood). His grandfathers Erasmus Darwin and Josiah Wedgwood were both prominent abolitionists. Erasmus Darwin had praised general concepts of evolution and common descent in his Zoonomia (1794), a poetic fantasy of gradual creation including undeveloped ideas anticipating concepts his grandson expanded. Both families were largely Unitarian, though the Wedgwoods were adopting Anglicanism. Robert Darwin, a freethinker, had baby Charles baptised in November 1809 in the Anglican St Chad's Church, Shrewsbury, but Charles and his siblings attended the local Unitarian Church with their mother. The eight-year-old Charles already had a taste for natural history and collecting when he joined the day school run by its preacher in 1817. That July, his mother died. From September 1818, he joined his older brother Erasmus in attending the nearby Anglican Shrewsbury School as a boarder. Darwin spent the summer of 1825 as an apprentice doctor, helping his father treat the poor of Shropshire, before going to the well-regarded University of Edinburgh Medical School with his brother Erasmus in October 1825. Darwin found lectures dull and surgery distressing, so he neglected his studies. He learned taxidermy in around 40 daily hour-long sessions from John Edmonstone, a freed black slave who had accompanied Charles Waterton in the South American rainforest. In Darwin's second year at the university, he joined the Plinian Society, a student natural-history group featuring lively debates in which radical democratic students with materialistic views challenged orthodox religious concepts of science. He assisted Robert Edmond Grant's investigations of the anatomy and life cycle of marine invertebrates in the Firth of Forth, and on 27 March 1827 presented at the Plinian his own discovery that black spores found in oyster shells were the eggs of a skate leech. One day, Grant praised Lamarck's evolutionary ideas. Darwin was astonished by Grant's audacity, but had recently read similar ideas in his grandfather Erasmus' journals. Darwin was rather bored by Robert Jameson's natural-history course, which covered geology—including the debate between neptunism and plutonism. He learned the classification of plants and assisted with work on the collections of the University Museum, one of the largest museums in Europe at the time. Darwin's neglect of medical studies annoyed his father, who sent him to Christ's College, Cambridge, in January 1828, to study for a Bachelor of Arts degree as the first step towards becoming an Anglican country parson. Darwin was unqualified for Cambridge's Tripos exams and was required instead to join the ordinary degree course. He preferred riding and shooting to studying. During the first few months of Darwin's enrolment at Christ's College, his second cousin William Darwin Fox was still studying there. Fox impressed him with his butterfly collection, introducing Darwin to entomology and influencing him to pursue beetle collecting. He did this zealously and had some of his finds published in James Francis Stephens' Illustrations of British entomology (1829–1932). Through Fox, Darwin became a close friend and follower of botany professor John Stevens Henslow. He met other leading parson-naturalists who saw scientific work as religious natural theology, becoming known to these dons as "the man who walks with Henslow". When his own exams drew near, Darwin applied himself to his studies and was delighted by the language and logic of William Paley's Evidences of Christianity (1795). In his final examination in January 1831, Darwin did well, coming tenth out of 178 candidates for the ordinary degree. Darwin had to stay at Cambridge until June 1831. He studied Paley's Natural Theology or.... Discover the Alexander Darwin popular books. Find the top 100 most popular Alexander Darwin books.
