Question

The forelimb of the monkey, bat, penguin, and alligator look

Answer 1

Answer:

The given examples shows homologous structures and divergent evolution.

Explanation:

• 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.
