Whales on the other hand are the opposite; they do not walk on four limbs like a cat. They spend their time swimming in the ocean, propelled by fins. b.       The homologous trait that these two animals possess is actually the forelimb structure of their bones. There are actually many species that share some type of forelimb structure.   The cat uses its front legs to walk, run and climb. They use the power of the forelimbs for speed and power. The whale uses its fins for swimming. The trait exhibits differences in the two species because they are influenced by the environment they live in, water versus land. This is why the cat has limbs and the whale has fins. c.        Given that both a cat and a whale are mammals; their common ancestor t...

The saying my mom used to always tell me is that there will always be someone with more than you and someone with much less whenever I happened to seem ungrateful for something. She is not wrong, it is a harsh reality that so...
