title: Human evolution: how recent were the Y chromosome ancestors?
abstract: Recent findings of low sequence variability of Y chromosome genes has led to suggestions that the most recent ancestor of human Y chromosomes existed around 50,000 years ago and human population size expanded about 28,000 years ago. But what level of confidence can we have in these estimates?
