Curvature...*

It was over 20 years ago when Sir Mix-A-Lot released "Baby Got Back," a love letter to bootlicious women everywhere. But men’s obsession with shapely butts has remained strong ever since. In fact, you might say that rears have replaced breasts as our most scrutinized body part.

What men are really drawn to isn’t so much the size of the derriere, but the curve or, more specifically, a spinal curvature that offers the illusion of a shapely butt.

Overwhelmingly, men preferred the uber-bendy images that showed the lower spine curved at a 45-degree angle, from back to buttocks.

But before those of you with pancake-flat cabooses get all cocky (or, shall we say, cheeky?), check this out: The reason has more to do with “prehistoric influences” than standards of beauty.

The right curve made it easier for women to not only carry babies, but to get off their bottoms and hunt down grub to feed the offspring.

Beauty is not entirely arbitrary, or ‘in the eyes of the beholder’  but rather has a coherent adaptive logic.” Which is“chauvinism that dates all the way back to Neanderthal times.

Big butts, small butts, whatever..... Suit yourself.    Just a thought.
