Question

How can fossil records provide evidence of common ancestry?A.Homologous bone structures can be compared between groups of organisms.B.The ages of fossils can be compared between groups of organisms.C.Soft tissue structures can be compared between groups of organisms.D.Embryological development can be compared between groups of organisms.

Answer 1

The correct option is A.Homologous bone structures can be compared between groups of organisms.

Explanation:

Scientists can learn a great deal about evolution with fossils, they can compare their anatomy with the one in living species.

If two or more species share a unique physical feature, such as a complex bone structure, they may all have inherited this feature from a common ancestor. Physical features shared due to evolutionary history (common ancestor) are said to be homologous.
