Demographic change of human populations is one of the central questions fordelving into the past of human beings. To identify major population expansionsrelated to male lineages, we sequenced 78 East Asian Y chromosomes at 3.9 Mbpof the non-recombining region (NRY), discovered >4,000 new SNPs, and identifiedmany new clades. The relative divergence dates can be estimated much moreprecisely using molecular clock. We found that all the Paleolithic divergenceswere binary; however, three strong star-like Neolithic expansions at ~6 kya(thousand years ago) (assuming a constant substitution rate of 1e-9/bp/year)indicates that ~40% of modern Chinese are patrilineal descendants of only threesuper-grandfathers at that time. This observation suggests that the mainpatrilineal expansion in China occurred in the Neolithic Era and might berelated to the development of agriculture.
