It has been suggested that older men in all cultures tend to marry women younger than themselves because men are genetically predisposed to seek female features associated with youthful fertility. This suggestion best illustrates
a. social learning theory.
b. behavior genetics.
c. freudian psychology.
d. an evolutionary perspective

This suggestion best illustrates D. an evolutionary perspective.

Explanation:

The evolutionary perspective seeks explanations for behaviors taking into consideration our species need to adapt and reproduce. From this perspective, our behaviors result from problems our ancestors encountered over 10,000 years ago. Since the purpose of the species is to perpetuate itself, many of our behaviors could be explained by the instinct of reproduction. We look for good mates in order to procreate. That perspective would, therefore, explain men who marry younger women as a result of our reproductive needs - young means fertile, at least instinctively.
