Question

[GT.03]A scientist studied the limb structures of three organisms and made their models as shown below.

Answer 1

Answer: They evolved from the same ancestor.  

Explanation:

This phenomenon is called Homologous organs. Different species which are closely related to each other tend to have relatable anatomical structures. This is because ,once upon a time, they belonged to a common ancestor from whom they diverged.

Food habits, competition , survival of the fittest- all these factors required each of these new species to develop their common organ in their own special way. This would make their survival easier. Thus, talons , claws , hooves are not as distantly related as they seem.
