On The Origin Of SpeciesHarper Collins, 22 июл. 2014 г. - Всего страниц: 336 Published in 1859, The Origin of Species by Charles Darwin introduced the theory of natural selection to a newly-receptive public. As a young naturalist on the second voyage of HMS Beagle (1831-36), Darwin collected many plant and animal specimens, and it was his close examination of them that eventually led to his theories on evolution and natural selection.
