The given examples shows homologous structures and divergent evolution.
<h2>Explanation:</h2>
Penguins, alligators, humans, monkey and bats are very different creatures. Nonetheless, they all have very similar structures. Each have a humerus, radius, ulna, and carpels in their forelimbs. Although each bone looks different in each species, the bones serve similar functions in the different organisms. This shows homologous structures.
Homologous Structure: A homologous structure is an example of an organ or bone that appears in different animals, which are anatomically similar structure demonstrating descent from a common ancestor.
This shows divergent evolution as they have evolved through common ancestor.
Result: The given examples shows that the animals have homologous structures.
