Why Are Evolutionary Psychologists So Fascinated with the Study of Infant

Why are evolutionary psychologists so fascinated with the study of infant reflexes?

A) Because all infant reflexes disappear within the first month of life, evolutionary psychologists want to know if those behaviors do, in fact, serve a necessary purpose.
B) Because only certain "types" of human beings demonstrate innate reflexes, and experts want to know whether this suggests that there are different stages of development of the human species.
C) Because the development of innate reflexes gives us information about how human beings adapt to changing circumstances over time.
D) Because some research has found that infant reflexes can, in fact, be taught to adults, and that these reflexes can serve a life-saving function in specific circumstances.
