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.
Explanation: Darwin's Theory of Evolution by Natural Selection is by far the best explanation for the great diversity of life that we see. Before Darwin's time, science knew that life evolved, since they saw the fossils (fossils were a popular spectacle back then) and their resemblance to extant life.
