![]() In establishing his theory, Darwin made considerable use of comparative anatomy, which revolutionized science by explaining anatomical variations between species as coming from their evolutionary descent by natural selection from a common ancestor. Instead, Cuvier classified all animals into four broad classes based on their body plans (vertebrates, mollusks, articulates, and radiates).Īnother notable person in the discipline was British anatomist Sir Richard Owen, mid-nineteenth-century, whose enormous understanding of vertebrate structure did not prevent him from criticizing British biologist Charles Darwin's idea of evolution by natural selection.
