Alfred Russel Wallace OM FRS (8 January 1823 – 7 November 1913) was an English [1] [2] [3] naturalist, explorer, geographer, anthropologist, biologist and illustrator. [4] He independently conceived the theory of evolution through natural selection; his 1858 paper on the subject was published that year alongside extracts from Charles Darwin's earlier writings on the topic.
The article was the first announcement of the Darwin–Wallace theory of evolution by natural selection; and appeared in print on 20 August 1858. The presentation of the papers spurred Darwin to write a condensed "abstract" of his "big book", Natural Selection. This was published in November 1859 as On the Origin of Species.
Lyell and Hooker agreed that a joint publication putting together Wallace's pages with extracts from Darwin's 1844 Essay and his 1857 letter to Gray should be presented at the Linnean Society, and on 1 July 1858, the papers entitled On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means ...
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.
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 ...
Darwinism: An Exposition of the Theory of Natural Selection with Some of Its Applications is an 1889 book on evolution by Alfred Russel Wallace, the co-discoverer of evolution by natural selection together with Charles Darwin. This was a book Wallace wrote as a defensive response to the scientific critics of natural selection. [1] Of all ...
The scientific theory of evolution by natural selection was conceived independently by two British naturalists, Charles Darwin and Alfred Russel Wallace, in the mid-19th century as an explanation for why organisms are adapted to their physical and biological environments.
He was on track to publish sometime between 1859 and 1861, but was interrupted by Wallace sending him a similar concept in 1858, so their essays were read together as papers "On the Tendency of Species to form Varieties; and on the Perpetuation of Varieties and Species by Natural Means of Selection". Darwin then wrote an abstract, titled On the ...
