Acting White: Black Women Series, Waist to Hip Ratio and Attraction

There are legions of men, and women, who think that a woman’s breast is the focal point of male-female attraction, but this is not the case. Even though breasts have garnered tremendous recent attention, they lag as the best indicators of reproductive fitness. This breast lagging (forgive the pun) is measurable in how men assign attractiveness, relative to breast size. We now know there is more influence in the waists and hips, and (of course) hair, as discussed here.

Research has shown that men are genetically programmed to instantly sight a woman’s waist to hip (WTH) ratio, giving the highest attractiveness rating to a ratio of approximately .7. This means if the waist is 25 inches, the preferred hip is 36, for US men. This rating correlates to estrogen levels and reproductive fitness. But is this preference true for African-male ancestries as well? Indeed it is, but with a twist.

Waist to hip studies measure the circumference. White men favor width from the frontal view, while black men favor width viewed in profile, hence the phrases, ‘flat-butt’ and ‘junk in the trunk’. But in both black and white scenarios, the preferred circumference measurements are close enough to say preference differences are minor across ethnicities, and are explainable.

In the male hunting-female gathering evolution of humans there is less gathering in locales further from the equator, like Europe and Scandinavia. This has caused the gatherers (women) to lessen their butts, while still maintaining the desirable WTH ratio. The women who remained closer to the equator kept the gluteus maximus muscles needed for the best gathering. (here)

The rub comes in when plentiful food and sedentary life styles cause obesity to explode, as in America. US men, like their world-wide counterparts, maintain their appetite for casual sex, but show a decline in willingness to sign on to long-term contracts to mates and offspring. This attraction and willingness, or not, to commit is baked into our brains. It is true that social conditioning can offset what our genes tell us to do, but only to a lesser degree.

The behavior of men is additionally influenced by the availability of casual sex, in the wake of declining estrogen-signaling attractiveness. The lowering of the WTH ratio in black women is further aided by the sedentary behavior resulting from costly hairstyles that ward off daily exercise routines. To be fair, men, black and white, also suffer bulging waistlines from obesity, however, testosterone-signaling attraction and behaviors of women toward men is a better subject for another post.
