I have heard much the same thing for my entire life; lifespans began
to drop with the switch from hunter-gatherer to agriculture. The
advantage appears to be population densities -- a simple matter of
how many mouths you can feed.

People didn't live even as long as Neanderthals but, evolution
works at the level of a population not an individual....

I've often argued this point with Aquatic Ape as exploiting the sea
can support a higher population density than inland hunter gathering.

Looking at Chimps:  The savanna supports the  _Lowest_ population
density!  So the idea that humans could have evolutionarily benefited
from a reduced gene pool seems odd, to say the least.
