You know, I’ve always thought that was pretty obvious. When you’re out hunting the best way to communicate with your breatheren without alerting the prey is with hand gestures. And it works alright even when the person you’re communicating with is quite a ways away.
You’d think so, but, apparently, like cavemen enjoying nookie, it is something that seems to have never occurred to the eggheads.
I imagine cavemen giving one another the finger before they even learned to point out food for one another. At least in Boston, that hasn’t changed thus far.
Are you referring to Tuckerfan’s caveman nookie thread? 
Well it does make sense. Babies can learn gestures and communicate through them before they can talk. Thus the popularity of “Baby Signs”.
You realize what this means?
Humanity evolved from mimes.
The poor mimes, frozen in an evolutionary dead end. LET’S KILL THEM!
Don’t you mean “Trapped in an evolutionary invisible box”?
Nah. That gesture was invented by the Mayans.
