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.
Darwin's theory of evolution by natural selection is entirely focused on an explanation of life's biological diversity. It is a scientific theory meant to explain observations about species. Yet some have used the theory to justify a particular view of human social, political, or economic conditions. All such ideas have one fundamental flaw: They use a purely scientific theory for a completely unscientific purpose. In doing so they misrepresent and misappropriate Darwin's original ideas. One such distortion and misuse is the loose collection of ideologies grouped under the label of Social Darwinism..
