Battle of the sexes benefits offspring, says research
Date:7/6/2009

"Some say that marriage is a state of antagonistic cooperation - in this case we found that the secret to a stable pairing was to only partially compensate for your lazy partner's failings, to make sure that they stick around."

Professor Innes Cuthill, Professor of Behavioural Ecology at the University of Bristol, added: "Of course, we are not claiming that fish and birds, or even humans, are necessarily making a consciously calculated decision.

"More likely there are innate rules for responding, perhaps modified through learning, that allow successful participation in joint activities without leaving room for being exploited."

The researchers hope that this work could help scientists better understand how biparental care has evolved in humans.
