The Mate-Attracting Elaborate Plumage of the Male Peacock is a Result

Question

The mate-attracting elaborate plumage of the male peacock is a result of:
A) genetic drift.
B) adaptation to the environment.
C) sexual selection.
D) gene flow.

Accepted Answer

The elaborate plumage of the male peacock is not essential for survival in its environment, so it is not an adaptation. It is also unlikely to be a result of genetic drift or gene flow. The most likely explanation is sexual selection, where the peahens choose males with the most elaborate and attractive plumage as mates.
