Booty, booty, booty has been rocking everywhere for ages. With popular songs like “Drop It Low” and “Baby Got Back” longtime staples in the rap community, it seems like mainstream press and pundits are late to the backyard boogie sensation. A new study from Bilkent University’s Dr. David Lewis claims that men’s interest in lady with the boom eminent from the curved spines that create them.

“[The curve] would have enabled ancestral women to shift their centre of mass back over their hips during pregnancy, a time during which there is a dramatic forward shift of their centre of mass,” Lewis claimed. “Without being able to do this, women would experience a dramatic increase in hip torque (pressure) subjecting them to risk of muscular fatigue and injury.” Scientists and researchers believe that this particular fact is what make men attracted to a woman with an ample backside.

Using the curved spine as an example, Dr. David Lewis, a psychologist at Bilkent University, claims that exactly 45 degrees above the top of her bottom is the ideal ratio of attraction. With this in mind, it is said that this would explain why female celebrities such as Jennifer Lopez, Nicki Minaj, and Kim Kardashian are considered to be super attractive. “Ancestral women who possessed this degree of lumbar curvature would have been able to forage longer into pregnancy and would have been able to carry out multiple pregnancies with a reduced risk of spinal injury,” Lewis said.

In the psychologist’s opinion, women without a 45 degree curve would have health problems tied to her hips during pregnancy that would increase the difficulty of giving birth. For the Bilkent University study, 300-plus men were asked to rate the attractiveness of female silhouettes that ranged in curvatures from 26 to 61 degrees. 45.5 was the moderate choice from the men polled, which, according to the study, would have confirmed evolutionary advantages.

In addition to the curvature ratio, the researchers learned that a woman’s spine structure, as opposed to just the buttocks’ fat and muscle, was key to attractiveness.

“Men may be directing their attention to the butt and obtaining information about women’s spines, even if they are unaware that that is what their minds are doing," Lewis added

The study, which was published online Feb. 7 in the journal Evolution and Human Behavior, concludes some interesting notions about the female anatomy. What do you, Tech Times reader, think about the findings? Speak your thoughts in the comments below.
