Question

If two different animal species are found to go through equivalent stages of embryonic development until the very last stage, which conclusion would this phenomenon support? A. The two animal species are very closely related. B. The two animal species are both mammals. C. The two animal species have identical DNA. D. The two animal species do not share a common ancestor.

Answer 1

The two animal species are very closely related.

Answer 2

The answer is A. The two animal species are very closely related.

If the two animal species are very closely related, that means their genome information is very similar and that information for embryonic development is also very similar, but it will not be identical. Stages of embryonic development from the beginning to the end are same only in the same species. In different species, they will differ in lesser or greater extent which depend on how closely this different species are related.
