As humans have also become much larger, that pure volumetric analysis stands out. I wonder what the "density" relationship would be. A denser cluster of neurons might be more efficient. Of course, my assumption is that we are getting smarter. Laughing.

2,000 years ago humans probably had to be smarter. As we developed technology to make life simpler we made the requirements for survival less demanding and, as a result, the intelligence level needed to survive was lowered. In fact, I can see where our dependence on society for survival may require us to be dumber.

I wonder how much of that shrinkage has occurred since Rupert bought Fox. Just kidding, folks

Dad, I was gonna make that crack, but even Mort Kondracke hasn't been around for enough of that 20,000 years to be statistically significant...

(And, yes, I really did just go looking for the oldest Fox commentator. I feel soooo dirty.)
