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.

The idea that humans shared a common ancestor with apes was a challenge to the foundations of western civilisation. Darwin kept silent for 20 years before going public and was only half joking when he described writing his book 'On the Origin of Species' as 'like confessing a murder'.
