Summary Introduction
Introduction: Sexual selection is a process of selecting mates by an individual. The selection will be according to the physical traits that usually attract the opposite gender. Increased size, coloration, and adornment appearance of the individual help in selecting a mate. Many factors influence the selection of a partner to mate. They include sexual dimorphism, exaggerated traits and male aggression, and so on.

How did Cowley explain this result? A. This is a trick question- this attraction is culturally relative B.
