Question

Significance of vestigial organs?

Answer 1

Common descent and evolutionary theory. Vestigial structures are often homologous to structures that are functioning normally in other species. Therefore, vestigial structures can be considered evidence for evolution, the process by which beneficial heritable traits arise in populations over an extended period of time.
