Write significance of vestigial organs.

Solution

Significance of vestigial organs. Organic evolution states that these vestigial organs were functional in the ancestral forms but have become nonfunctional due to changes in their function and may finally disappear. So the presence of vestigial organs is a convincing evidence of organic evolution and is supported by Lamarck's theory of use and disuse of organs.
