Runaway Sexual Selection Hypothesis

Proposal of sexual selection that is an alternative to the handicap principle. It posits that females in an ancestral population preferred a particular elaborate trait in males and that the resulting female offspring inherited genes for the preference of males with these elaborate traits. Because these genes are inherited together there is a positive feedback loop that amplifies the presence of these alleles in the population. Aka runaway selection.
