Why Big Butts Are Good

Intelligence.

There is a moderate correlation between maternal WHR and cognitive measures of their offspring. Using data from the U.S. National Center for Health Statistics, William Lassek at the University of Pittsburgh in Pennsylvania and Steven Gaulin of the University of California, Santa Barbara, found a child’s performance in cognitive tests was linked to their mother’s waist-hip ratio, a proxy for how much fat she stores on her hips.

Children whose mothers had wide hips and a low waist-hip ratio scored highest, leading Lassek and Gaulin to suggest that fetuses benefit from hip fat, which contains long chain polyunsaturated fatty acids, critical for the development of the fetus’s brain. In addition, evidence suggests that children of low-WHR teens were protected from the cognitive deficits often associated with teen birth.

It appears that men are more influenced by female waist-size than hip-size:

“Hip size indicates pelvic size and the amount of additional fat storage that can be used as a source of energy. Waist size conveys information such as current reproductive status or health status … in westernized societies with no risk of seasonal lack of food, the waist, conveying information about fecundity and health status, will be more important than hip size for assessing a female’s attractiveness.”
