The Descent of Man, and Selection in Relation to Sex is a book by English naturalist Charles Darwin, first published in 1871, which applies evolutionary theory to human evolution, and details his theory of sexual selection, a form of biological adaptation distinct from, yet interconnected with, natural selection.
Charles Lyell recognised the implications of Wallace's paper and its possible connection to Darwin's work, although Darwin did not, and in a letter written on 1–2 May 1856 Lyell urged Darwin to publish his theory to establish priority. Darwin was torn between the desire to set out a full and convincing account and the pressure to quickly ...
Emma Darwin with Charles Waring Darwin. Charles Waring Darwin, born in December 1856, was the tenth and last of the children. Emma Darwin was aged 48 at the time of the birth, and the child was mentally subnormal and never learnt to walk or talk. He probably had Down syndrome, which had not then been medically described.
These aspects of Darwin's personal life are discussed in the psychoanalytic biography Charles Darwin, A Biography (1990) by John Bowlby. [20] Darwin contrasts his idea of a shared human and animal ancestry to the ideas of Charles Bell, which are aligned with natural theology.

The concept, published by Darwin and Alfred Russel Wallace in a joint presentation of papers in 1858, was elaborated in Darwin's influential 1859 book On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. He described natural selection as analogous to artificial selection, a ...
The biogeographical patterns Charles Darwin observed in places such as the Galápagos Islands during the second voyage of HMS Beagle caused him to doubt the fixity of species, and in 1837 Darwin started the first of a series of secret notebooks on transmutation. Darwin's observations led him to view transmutation as a process of divergence and ...
Even if reported wrongly, putative last words can constitute an important part of the perceived historical records [2] or demonstration of cultural attitudes toward death at the time. [1] Charles Darwin, for example, was reported to have disavowed his theory of evolution in favor of traditional religious faith at his death. This widely ...
Charles Darwin in 1868. Darwinism is a term used to describe a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others. The theory states that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
