How men are conned by a woman's sexy wiggle of the hips…
The sight of a woman's sashaying hips may be enough to make a man go weak at the knees. But he may well be reading too much into her behavior.
A study has shown that women walk with a wiggle when they are at their least fertile - and adopt a less "sexy" gait when they are more likely to conceive. The apparently contradictory finding - which belies earlier evidence that women's behavior becomes more alluring around the time of ovulation - amounts to an evolutionary con-trick on men, scientists said.
This is because genuine signals of sexual availability, such as subtle changes in smell and facial expressions, can be detected only close up. Men who pick up on these signs are likely to be close friends and acquaintances - and therefore more suitable fathers.
However, signals such as gait can be spotted at a distance by strangers who could be unsuitable mates. Having a less-attractive walk around the time of ovulation therefore allows a woman to disguise her fertile period from undesirable men, it is suggested.
