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.

Famous quotes containing the words reward and/or hypothesis:
“The reward of a thing well done, is to have done it.”
—Ralph Waldo Emerson (1803–1882)
“The hypothesis I wish to advance is that ... the language of morality is in ... grave disorder.... What we possess, if this is true, are the fragments of a conceptual scheme, parts of which now lack those contexts from which their significance derived. We possess indeed simulacra of morality, we continue to use many of the key expressions. But we have—very largely if not entirely—lost our comprehension, both theoretical and practical, of morality.”
—Alasdair Chalmers MacIntyre (b. 1929)
