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.
Natural selection and adaptation are two basic concepts which are coming under Darwinâs Theory of Evolution. In Darwinâs theory, he said that all life is related and has descendants from a common ancestor. All species, therefore, can include in a vast tree of life. Natural selection is the known cause of adaptations, but the other non-adaptive causes like mutation and genetic drift are also responsible for evolution of life on earth.
