New Research Explains Why Men Love Women with Big Butts

Researchers at Bilkent University in Turkey showed 300 men silhouettes of women’s bodies and asked to rank them in order of preference.
They found that the men were most attracted to women whose spines curved exactly 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.
Why? The researchers say that having “extra mass around the buttocks” enhanced the appearance of the curvature.
Dr. David Lewis, one of the researchers on the study, told Daily Mail that vertebral wedging developed out of necessity. “[It] would have enabled ancestral women to shift their center of mass back over their hips during pregnancy, a time during which there is a dramatic forward shift of their center of mass,” he said. “This benefit is critical: Without being able to do this, women would experience a dramatic increase in hip torque, subjecting them to risk of muscular fatigue and injury.”
Subsequently, women who developed this vertebral wedging were able to “forage longer” for food during pregnancy and carry multiple 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.
Dr Lewis said that this trait would have become sexually attractive to men due to the evolutionary advantage it gave.
Without such a curve, the pressure on a woman’s hips during pregnancy increases by nearly 800 per cent, rendering her largely immobile and increasing the risk of health problems.
However, the researchers noted that the study isn’t conclusive and that more research is needed to really understand the preferences for either a big butt or a pronounced spinal curve.
