Charles Darwin wrote a book called The Descent of Man In Selection in Relation to Sex, which was originally released in 1871. It describes his sexual selection theory, a type of biological adaptation that differs from natural selection yet is tied to it.Outlining how similar humans are to other animals is Darwin's strategy for supporting the evolution of people. He starts by drawing parallels between the anatomical structures, emphasizing body composition, embryology, and "rudimentary organs" that are presumed to have had a purpose in one of man's "pre-existing" forms.Darwin argued that there is no fundamental distinction between the intellectual, moral, and anatomical capacities of humans and those of other animals. Based on anthropology published since 1860, he assigned a hierarchical ranking to all aspects of life and extended it to include human races.The Sexes Throughout Nature, written by Antoinette Brown Blackwell and published in 1875, served as the foundation for Darwin's theory of evolution by natural selection. One of the first female critics of evolutionary theory, Blackwell said that it denied women their proper role in society.The majority of Descent is devoted to the discussion of sexual selection, which Darwin believed to be as important a theoretical contribution as his work on natural selection.
Charles Darwin was a naturalist earned fame for the 'Theory of Evolution'. He was born on 12 February 1809 in Shrewsbury England. His father Robert Waring Darwin was a medical doctor and mother Susannah Wedgwood belonged to a famous pottery family. In his childhood he went Shrewsbury School, academically he was not good. For advanced learning, his father send him to Edinburgh University in Scotland to become a doctor but he was not interested and he joined Christ's College Cambridge. His interests developed in botany thus, he studied John Stevens Henslow's course in botany, though he completed his graduation in 1831. As a naturalist Darwin got an opportunity to go to second sea voyage of H.M.S. Beagle to survey the coast of South America. On his voyage he studied plants and animals life. His interests in life science evolved and after working more than 20 years, in 1859 his world fame work 'On the Origin of Species' was published. He explained theory of evolution by natural selection. He said that life on earth evolved from a common ancestors. On earth there is struggle for survival between members who have favourable traits they survive and reproduce, it is known as survival of fittest. Well adapted species survived and less became extinct. Earlier Darwin faced criticism but later he earned honour for the theory. Darwin died on 19 April 1882.
