A new study has revealed there's a reason why blokes prefer bigger butts.
From Kim Kardashian's Champagne glass trick to Iggy Azalea and J-Lo's music vid to Nicki Minaj's Anaconda, it would seem larger backsides are in fashion.
And science has apparently proven it.
A new study has discovered a scientific reason for men's interest in prominent butts; we're actually interested in curved spines.
"Women with a greater degree of lumbar curvature ... were able to redistribute this center of mass to reduce the strain of pregnancy.
"Thus, we hypothesized that men should have a psychological adaptation to prefer these women as mating partners," a scientist with too much time on his hands said.
So, in other words, women who were able to have lots of babies and forage productively during pregnancy back in the day.
For the study, more than 300 men rated the attractiveness of female silhouettes that had lumbar curvatures ranging from 26 to 61 degrees.
Most of the men found 45.5 degrees to be perfect. Such a curvature would have conferred evolutionary advantages without presenting health problems like back pain and slipped disks, the researchers said, at which point we fell asleep.
The study was published online Feb. 7 in the journal Evolution and Human Behavior.
So, in summary....
