While home for winter break, you start telling your grandmother about your physical anthropology class. She once heard about a man who became a body builder and then produced muscular children, and she asks you to explain how this could happen. You say that:________.
A) Inheritance of acquired characteristics is a fundamental tenet of Darwin's theory of evolution.
B) This is an example of Lamarckism, which has some kernels of truth about evolution but is not a wholly accurate theory.
C) Malthu's ideas about how food supply limits populations growth mean that a body building will be more successful at procuring food and reproducing.
D) This illustrates Mendel's idea that inherited traits are not blended.

Lamarckism is a theory of evolution based on the principle that physical changes in organisms that occurred during their lifetime through use and disuse of body parts - such as greater development of an organ or a part could be transferred to their offsprings.

Although, genetic mutation could be the cause of muscular children. A genetic mutation is a sudden inheritable change that is quantitative or qualitative. Genetic mutation can result in a condition where the cells of the muscle grow bigger and divide more rapidly which results in a condition where people, and even children can look like body builders.
