Quizplus · Accepted Answer

The similarity between the forearm of a human and an alligator suggests that they share a common ancestor, as evidenced by their homologous structures. This is a concept in evolutionary biology known as homology, where similar features in organisms can be traced back to a common ancestor. It does not suggest that humans are reptiles, laid eggs, or that alligators descended from mammals. The most likely explanation is that both alligators and humans experienced convergent evolution, where they both independently evolved similar structures to adapt to similar environments.
