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.
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 ...
Wallace collected specimens and corresponded with Darwin from Borneo. In December 1857, he wrote to ask if Darwin's book would delve into human origins, to which Darwin responded that "I think I shall avoid the whole subject, as so surrounded with prejudices, though I fully admit that it is the highest & most interesting problem for the ...
In 1858 Charles Darwin and Alfred Russel Wallace published a new evolutionary theory, explained in detail in Darwin's On the Origin of Species (1859). Darwin's theory, originally called descent with modification is known contemporarily as Darwinism or Darwinian theory.
It was at this stage that Alfred Russel Wallace became involved and Darwin's work took on a new urgency. While Darwin continued to amass knowledge and carry out experiments, he now became committed to publication. See the publication of Darwin's theory for the resulting developments, in the context of his life, work and outside influences at ...
In addition, Alfred Wallace independently used the concept of the struggle for existence to help come to the same theory of evolution. [3] Later, T.H. Huxley further developed the idea of the struggle for existence. Huxley did not fully agree with Darwin on natural selection, but he did agree that there was a struggle for existence in nature. [4]
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]
Although Alfred Russel Wallace completely rejected the concept in favor of natural selection, Darwin always included what he called Effects of the increased Use and Disuse of Parts, as controlled by Natural Selection in On the Origin of Species, giving examples such as large ground feeding birds getting stronger legs through exercise, and ...
