Please quote published research.
There is work on Paleolithic teeth that is often used as evidence to suggest that Paleolithic humans lived longer than early farmers (http://www.nytimes.com/2013/03/24/magazine/who-lives-longest.html). I worry about the sample sizes. Is there any additional bulletproof evidence to support this claim?
Or is this in fact false and is there strong evidence to suggest Neolithic farmers experienced a marginal improvement in lifespans due to the innovation of farming?
