Document Summary

Adaptive radiation: the diversification of one founding species into multiple species that exploit different habitats. He believed that all the species diverged from one original group and developed certain features that enabled them to survive longer, these features (mutations) would be passed on to offspring. Darwin was not the only one to come up with the idea of natural selection; alfred russel. Wallace was stationed in indonesia and was collecting species just like darwin. Differential fitness: differential survival, differential reproduction, genetic contribution to the next generation is focused on here. Competition for limited resources (struggle for existence) Inheritance (passed on traits that help population survive) 1859 (on the origin of species by means of natural selection) published. Lamark"s theory of vitalism is put into question. Evidence for evolution: artificial selection (domestication, geographic distribution (biogeography, paleontology, comparative anatomy (whale/bird/dog/human have similar arm/hand bone structure, embryology (various different species have similar first stage embryos)
