Do Men Really Prefer Big Butts? Science Has the Answer

In fact, you might say that rears have replaced breasts as our most scrutinized body part. In the study, approximately men, between the ages of 17 to 34, were asked to rate the attractiveness of images of a woman's silhouette as she stood sideways. Each image had been altered so the lower spine curved out at different angles—causing the woman's butt to protrude in varying extremes. What researchers found: Overwhelmingly, men preferred the uber-bendy images that showed the lower spine curved at a degree angle, from back to buttocks.

Acceptable, so by now everyone has seen Kim Kardashian's booty-baring , Internet-breaking camouflage for Paper magazine. And sure, as Kim's bare bum is a blow on some levels, but what's after the deeper, visceral reaction to the pics? Nowadays -- if popular composition is to be believed -- we're currently all about that bass. Butts are clearly having, well, their biggest moment ever, a fact that evolutionary psychologists like Gordon G. Gallup Jr. According to Gallup, men's attraction en route for women with bigger butts -- accompany Trainor's assertion that boys like a little more booty to hold by night -- is woven into their genes.

Butts are definitely having a momentand at once science might actually have an come back with to why we're all about so as to bass. Researchers at Bilkent University all the rage Turkey showed men silhouettes of women's bodies and asked to rank them in order of preference. They bring into being that the men were most attracted to women whose spines curved accurately 45 degrees above the top of their butts, but that the men were actually more attracted to the spinal curve — known as vertebral wedging — than the butts themselves. The researchers say that having above mass around the buttocks enhanced the appearance of the curvature. David Lewis, one of the researchers on the study, told Daily Mail that vertebral wedging developed out of necessity. After, women who developed this vertebral wedging were able to forage longer designed for food during pregnancy and carry compound pregnancies with a lower risk of injury, which Dr. Lewis says would have been sexually attractive to men because of the evolutionary advantage it provided. However, the researchers noted so as to the study isn't conclusive and so as to more research is needed to actually understand the preferences for either a big butt or a pronounced spinal curve.
