Sex and Reward Hypothesis
Schroder reviews a hypothesis by Symons' and Hill's that hunting males exchanged meat for sex with females.

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.
