Question

Though vestigial organs do not perform any function in the body, they provide some evidence in the field of organic evolution. How?

Answer 1

Vestigial organs suggested that how species are related to each other and originated from a common ancestor. The vestigial organs that were once necessary for the survival of an organism during the course of evolution gets functionless as the organism gets adapted to new environmental conditions for survival. So, in those conditions that particular organ is not required so it gets vestigial.
