Faithful females who choose good providers key to evolutionary shift to modern family, study finds

John Neumann for RedOrbit.com Chest-thumping and grunting alpha males, a study suggests, may be losing the battle for preferable females to males who can demonstrate caregiving and the ability to provide for a family, according to research published in the Proceedings of the National Academy of Sciences. The research team says they have demonstrated mathematically that the transition to pair-bonding was based on female choice and faithfulness, so that providing for females became a better way of getting sex than showing competition between males, reports Adriana Barton for Globe and Mail. The effect is most pronounced in low-ranked males who would have a poor chance of winning a mate in a fight. "Once females begin to show preference for being provisioned, the low-ranked males' investment in female provisioning over male-to-male competition pays-off," says Sergey Gavrilets of the National Institute for Mathematical and Biological Synthesis and a professor at the University of Tennessee-Knoxville.
