Question

Name two homologous structure in vertebrates . Why are they so called

Answer 1

homologous structures in vertebrates - Limbs of birds, mammals, amphibians and reptilesThey are so called since they have similar basic structural plan, but appear different externally and perform different function. However they have evolved from a common ancestor.

Answer 2

The bones of tetrapods, or vertebrates with legs, are homologous in the forelimb. The bones in the wing of a bird, the hand of a primate, the paw of a cat and the flipper of a dolphin are all different in function, but are very similar and have evolved from a common ancestral structure.
