Sex and Reward Hypothesis
Schroder reviews a hypothesis by Symons' and Hill's that hunting males exchanged meat for sex with females. Females who continuously mimicked estrus may have benefited from more meat than those who did not. If this occurred with enough frequency, then a definite period of estrus would have been lost, and, with it, sexual signaling specific to ovulation would have disappeared.
