Question

Aristotle's classification include both fish and whale under one group. How are these unrelated?

Answer 1

Many unrelated organisms are placed in the same group on the basis of their habitats. Also, both fishes and whale are vertebrate. In this aspect, whales and fishes are in the same group. However, they are unrelated because whales are mammals and not fishes. Fish breathes through gills It is a cold-blooded animal. Whale breathes through lungs. It is a warm blooded animal.
