Question

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

very different on the outside, but their skeletal structures are
similar. This evidence suggests that these animals

Answer 1

Answer: A -may have evolved from a common ancestor.

Step-by-step explanation:

Answer 2

The given examples shows homologous structures and divergent evolution.

Step-by-step 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.
