Sir Edward Bagnall Poulton, FRS^[1] HFRSE FLS (27 January 1856 – 20 November 1943) was a British evolutionary biologist, 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 recognise frequency-dependent selection. He is remembered for his pioneering work on animal coloration and camouflage, and in particular for inventing the term aposematism for warning coloration. He became Hope Professor of Zoology at the University of Oxford in 1893.^[2]
