Yes—in simple terms, that’s basically what the study suggests.
Around 5,000–7,000 years ago, many parts of the world saw the rise of patrilineal clans (male-line descent groups). These clans often engaged in violent conflicts, and when one group wiped out another, the defeated men's Y-chromosomes disappeared entirely—because Y-chromosomes are passed only from father to son.
Meanwhile, women were often absorbed into the winning groups through marriage or capture, so mitochondrial DNA (inherited through mothers) stayed more diverse.
So yes:
> A few dominant male lineages “won” through violence or social dominance, and their genes spread while others vanished.It’s less about individual “violent men” and more about structured, male-led kin groups violently outcompeting others, reshaping the genetic landscape for millennia.
