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 established extinctions as a fact that any future scientific theory of life had to explain. In Darwin's theory, species that did not adapt to changing environments or withstand the competition of other species faced annihilation.Darwin did not, however, accept all of Cuvier's ideas on extinctions.y the 1700s, fossils had been inducted into the living world. Instead of being produced by rocks themselves, fossils were recognized as the remains of animals or plants.
