Topic: Comparative Anatomy

Introduction:

Analogous structures are features of different species that are similar in function but not necessarily in structure and which do not derive from a common ancestral feature and which evolved in response to a similar environmental challenge. However, if two structures have the same function and also start from the same origin, they are homologous structures.

Step-by-step explanation:

Humans, apes, cats, dogs, and more share a large, hollow chest cavity protected by ribs. However, the morphology of the thoracic cavity in each of these species has some different characteristics. Now note that the species in the problem are all mammals and come from a common ancestor. Therefore, we can conclude that the correct answer is:

Answer:

Homologous structure
