Question

Embryology provides evidence for evolution because

A. studying organisms during their early development provides clues as to how the adult functions.
B. during their development, embryos experience genetic mutations, some of which allow the embryo a better chance of survival.
C. during their development, many organisms look similar, suggesting that very different organisms may have a common ancestor.
D. studying organisms during their early development gives insights as to the organism's diet and how it has changed over many generations.

Answer 1

C

Step-by-step explanation:

During their development, many organisms look similar, suggesting that very different organisms may have a common ancestor. - Think of the human fetal neural / spine development which mirrors other species.

Answer 2

C. during their development, many organisms look similar, suggesting that very different organisms may have a common ancestor.

Step-by-step explanation:

During embryological development, the intermediate stages of one group of organisms exhibit stages of evolution in form of features of other groups. This suggests that the given group must have a common ancestor with the other group. It is called "ontogeny repeats phylogeny".

Example: Human embryo has a tail which otherwise is the feature of reptiles.
