Question

Male peacocks have large colorful tails that they spread in a fan shape to attract females during courtship. Peahens (female peacocks) are more likely to mate with males that have larger and more colorful tails. As a result, few peacocks have tails with dull coloring.

A male peacock.

Which concept is demonstrated by a decrease in dull coloring?
speciation
biodiversity
natural selection
variation

Answer 1

natural selection

Female choice causes males with colorful tails to have greater reproductive success, so genes for dull coloring become less common — an example of natural (sexual) selection.
