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