If you can see, you may have noticed that women have curves where men have none. So have scientists, who have long wondered why women tend to store so much fat around the buttocks and thighs. After all, while other mammals male and female have only five to 10 percent body fat, women have roughly 30 percent on average.
Now, we finally have the answer. News.com.au reports that it all had to do with babies’ brains. These stores of fat are essential to the development of babies’ brains, especially during breastfeeding when the fat is stripped away from women’s thighs and bottoms to help the baby.
Researchers also found that the quantity of these fat supplies may directly affect a child’s intelligence and chance of survival. This may be why some men are hardwired to prefer curvier women.
Professor Will Lassek of the University of Pittsburg, who published a book called Why Women Need Fat, told News.com.au that the fats in women’s thighs and buttocks are high in docosahexaenoic acid, or DHA.
“You need lots of fat to make a nervous system,” he said. “And the fats in these areas are also enriched in DHA, which is a particularly important component in the human brain. It looks as if women have evolved to accumulate these fats and hold on to them — until a baby arrives.”
