Which of the following statements is/are true?

A. Homologous structures might look and function similarly. This is probably due to a common ancestor with a similar trait.

B. Some homologous structures have similar morphology (shape, appearance)

C. Some homologous structures have the same function.

D. Homologous structures in descendants could be found in a common ancestor

E. Analogous structures are never due to common ancestry.

Answer: Option A, C, D and E.

Explanation:

Homologous structures are structures that look alike or appear similar in organisms that are related due to common ancestor. Homologous structures might look the same and function similarly due to common ancestor with similar traits. Some homologous structures have the same function and homologous structures found in descendants could be found in ancestors.

Analogous structures are structures that are similar and perform similar structures and are not from common ancestors.
