Neolithic team selection explains gender culture

The Neolithic Y‑chromosome bottleneck produced intense selection for male teamwork and coalition traits, which the author argues have persisted and help shape modern male social behaviour, institutions, and cultural patterns. The claim ties a specific genetic event to present‑day differences in hierarchy, team orientation, and gendered social dynamics. — If accepted or amplified, this causal story would recast debates about gender gaps, schooling, sports policy, and cultural change as partly rooted in deep evolutionary history, changing what kinds of interventions people consider legitimate.
