Options

A. analogous and vestigial organs
B. homologous organs only
C. homologous and analogous organs
D. homologous and vestigial organs

Answer

D

Explanation

An important evidence in favour of organic evloution is the occurrence of homologous and vestigial organs. Homologous organs are those which have the common origin and built on the same fundamental and have different appearances, e.g. whale's flipper, bat's wings, cat's paws, horse's front legs, bird's wings, ox's front legs and human hands.
Vestigial organs in anmals are those having no function now, in them, but had important functions in their ancestors.
Analogous organs are quite different in fundamental structure and embryonic origin but perform the same function. The study of analogous organs illustrates the occurrences of convergent evolution.
