Comparative anatomy helps prove evolution by showing similarities in the structures and forms of different species. According to the theory of evolution, organisms that share a common ancestor will also share similarities in their anatomical structures. By studying and comparing the anatomical features of different species, scientists can identify these similarities and trace the evolutionary relationships between them. For example, the presence of similar bone structures in the limbs of different mammals can be evidence of a common evolutionary origin, supporting the idea of descent with modification. Additionally, vestigial structures, such as the remnants of hind limbs in modern whales, provide further evidence for evolution by suggesting that these structures were inherited from ancestors that used them for a different purpose. Overall, comparative anatomy provides valuable insights into the evolutionary history of life on Earth and strengthens the evidence for the theory of evolution.
