Women With Bigger Butts Have Smarter Kids, Says Science

Bigger Butts Are Better For Babies

Whoa. Who knew?!

When women ask, "Does this make my butt look big?" it strikes men with fear. Well, now it may be OK to say yes, as science has found that mothers who have larger butts make more intelligent children.

A study from the University of Pittsburgh has found that the development of babies' brains depends on fat supplies that are located in their mom's behinds and thighs, and the amount stored there might directly influence a child's intelligence. 

"The fat in these areas is a depot for building a baby's brain," William D. Lassek, M.D, author of Why Women Need Fat told The Sunday Times. The fat supplies a chemical known as docosahexaenoic acid (DHA) which Lassek says is "a particularly important component in the human brain." It's an omega-3 fatty acid that babies need for the development of their brain's nervous systems and eyes in their first six months of life. This chemical is found in breast milk.

According to the study, "Upper-body fat has negative effects and lower-body fat has positive effects on the supply of long-chain polyunsaturated fatty acids that are essential for neurodevelopment. Thus, waist-hip ratio (WHR), a useful proxy for the ratio of upper-body fat to lower-body fat, should predict cognitive ability in women and their offspring."

"It looks as if women have evolved to accumulate these fats and hold on to them — until a baby arrives," Dr. Lassek said. "This is similar to the levels seen in bears going into hibernation or whales living in cold arctic seas."

I would be careful comparing women to bears and whales, whether they're expecting children or not.

The study also notes that "the unusual fattiness and fat deposition patterns of reproductive-aged women may be the result of natural selection for the ability to support fetal and infant neurodevelopment — a selection pressure that was much weaker in our close primate relatives."

At least we now know why so many women think of their thighs and butt as problem areas. It isn't that they have no discipline; it's simply evolution.
