•offer a possible evolutionary explanation for how the skeletons can be similar but the functions be very different in each of the animals

Such organ shows that these organisms share a common ancestry.

Explanation:

Organs with similar skeleton but different functions, such organs are known as homologous organs. homologous organs can be stated as - An organ that appears in different animals, underlining anatomical similarities which explain they are descended from a common ancestor.

When very different animals have bones that look very similar in form and seem to be related or having similar ancestors. Such as human arm, bat wings, dolphin fins, and others.

Thus, homologous organs show that these organisms are rise from the same ancestor.

due to the fact that it skipped a generation we can tell it is definitely not a dominant trait, therefore it must be recessive. i think this is right let me know!
