It should prove interesting, but I don't like the question it poses. Would we be better off as cavemen. That's silly. You just have to look at some of the remaning hunter gatherer tribes to answer that question. At least they are thoroughly adapted to their environment. I can't say the same about a bunch of city slickers playing caveman re-enactment. Anyway, I think the answer to that question would be yes and no. Some aspects of life was better and some not.
