Cultural hitchhiking and competition between patrilineal kin groups explain the post-Neolithic Y-chromosome bottleneck
An abrupt population bottleneck specific to human males has been inferred across several Old World (Africa, Europe, Asia) populations 5000–7000 BP.
population genomic studies and mathematical models, we propose a sociocultural hypothesis, involving the formation of patrilineal kin groups and intergroup competition among these groups
analysis shows that this sociocultural hypothesis can explain the inference of a population bottleneck
I wonder what effects on cultural and scientific evolution , a more diverse Y-chromosome would have.
