From the New York Times:
“Although Alfred Russel Wallace made one of the most important scientific discoveries in history, he’s been all but forgotten. A contemporary of Charles Darwin, Wallace was the other guy to discover natural selection – the evolutionary process whereby better adapted organisms are more likely to survive and pass on their traits than less adapted ones. Although two people discovered this theory, evolution by natural selection is virtually synonymous with Darwin. This is partly due to the lasting fame of Darwin’s opus, “On the Origin of Species,” but some argue it is also due to Wallace’s extraordinary modesty – he lauded Darwin’s work and humbly downplayed his own contributions. In 1889 he even wrote a book in support of evolution titled ‘Darwinism.'”
