Question

question 14 of 20 : select the best answer for the question. 14. embryology provides evidence for evolution because
a. during their development, embryos experience genetic mutations, some of which allow the embryo a better chance of survival.
b. studying organisms during their early development gives insights as to the organism’s diet and how it has changed over many generations.
c. studying organisms during their early development provides clues as to how the adult functions.
d. during their development, many organisms look similar, suggesting that very different organisms may have a common ancestor.

Explanation:

• Option A: Genetic mutations during embryo development are more about individual survival and not direct evidence for evolution's common ancestry, so A is incorrect.
• Option B: Embryology is not mainly about an organism's diet changes over generations, so B is wrong.
• Option C: How an adult functions from embryo study is not the key evidence for evolution, so C is incorrect.
• Option D: The similarity in early development of many organisms (like vertebrate embryos having similar stages) suggests a common ancestor, which is the core of embryological evidence for evolution.

Answer:

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