Important and rare contribution to Darwinism, partly based on new discoveries by Hugo de Vries (the rediscoverer of Mendel's laws) on mutations. Dedicated to Alfred Russel Wallace, it contains chapters on Darwin's life, letters by Darwin to Roland Trimen, the value of colour in the struggle for life, mimicry in North American butterflies, and appendices on Darwin and the hypothesis of multiple origins, Darwin and evolution by mutation, Darwin and the necessity of scientific work, etc.. Sir Edward Bagnall Poulton (1856-1943) "...was a British evolutionary biologist who was a lifelong advocate of natural selection through a period in which many scientists such as Reginald Punnett doubted its importance. He invented the term sympatric for evolution of species in the same place, and in his book The Colours of Animals (1890) was the first to recognize frequency-dependent selection. Poulton is also remembered for his pioneering work on animal coloration. He is credited with inventing the term aposematism for warning coloration, as well as for his experiments on 'protective coloration' (camouflage)" (Wikipedia). Fore and bottom edge uncut. Zoological pictorial bookplate of the British osteologist, zoologist and natural history writer William Plane Pycraft (1868-1942) on the front pastedown. A very good copy.
