Ancient humans learned to smile as a way to get sex

 

Evolutionary biologists have figured out why ancient humans developed the ability to SMILE.

 

And . . . shocker . . . it’s for the same reason we do everything else.  To get laid.

Scientists from the University of Milan studied genes from Neanderthals and found that they smiled to show they weren’t being AGGRESSIVE . . . which attracted less-aggressive people back to them.  And then they’d get-it-on.

 

And because one Neanderthal who’d developed the ability to smile got-it-on with another Neanderthal who’d developed the ability to smile, they passed on the ability to smile to their babies . . . and eventually, it became a universal ability.

And we’ve kept that ability to smile not just for sexual purposes . . . but for every circumstance where we want to make it clear we’re being friendly and not aggressive.
