He Likes Big Butts? Man Might Actually be Eyeing the Spine

You've probably heard it on TV and social media. This is the "Age of the Big Butt," where society's concept of beauty is increasingly coinciding with sex appeal and a love for curves. A large-but-toned backside in particular is supposedly the new vogue (even if men have been staring at them for centuries). Now, researchers from The University of Texas (UT) at Austin explain that our fascination with the butt is being driven by evolution, and it may actually be all about the spine.
