There will be at most something like 5000 de novo mutations along any evolutionary line from 3400 BP. Compare that to 3 million differences between any two human genomes. It's clear from this basic fact that very little evolutionary time has passed, and people from then and now would be indistinguishable in virtually all aspects.
