One evolutionary psychologist hypothesizes that humans were savage in their distant past, while another hypothesizes that they were very cooperative. Based on information from the authors of your text, which hypothesis is correct?
a. Neither: evolutionary explanations tend to be misguided.
b. Humans were cooperative; otherwise the species would not have survived.
c. Human were savage; otherwise we would all get along and be peaceful today.
d. Either: evolutionary psychology alone cannot discern which is correct.
Question 2
According to the authors of your text, one of the major problems with relying solely on evolutionary theory as the only explanation for social behavior is that
a. psychologists are making assumptions about the conditions that existed long ago that produced reproductive advantages for certain genes.
b. it defies religious explanations, which are core beliefs for many people in the U.S.
c. social behaviors are not based on genes at all, so it is difficult to use evolution to predict behavior.
d. evolution occurs too slowly for it to truly impact human behavior.
