Darwin's evidence for evolution. In his Origin, Darwin presents his evidence supporting descent with modification (branching evolution) in several chapters: A. In Chapters 1 and 2, he considers how patterns of variation in domesticated and wild fauna and flora support descent with modification. B. In Chapters 10-12, he shows how the patterns of species distributions in time and space support branching evolution from common ancestral lineages.
Cuvier's work on the extinction of animals and the progressive creation of new species provided a ground work for Darwin's theory of evolution. Cuvier established proof that many species like dinosaurs had become extinct in ages past. Cuvier proposed that after each series of catastrophes new species had been created. Cuvier's work on extinctions was incorporated into Darwin's theory of natural selection and survival of the fittest.
