Abstract in brief

  • The discovery of an ancient African American Y chromosome called A00 reveals it carries the most ancestral genetic markers, dating back approximately 338,000 years, which is much older than other estimates for human mitochondrial DNA and fossil records.
  • The rarity of the A00 lineage, found at low frequencies in central Africa and not in traditional hunter-gatherer populations, suggests complex origins involving ancient population structures or archaic gene flow into modern humans.
  • This finding highlights the challenges in interpreting human origins solely based on single genetic loci like the Y chromosome, emphasizing the need to consider more intricate models of human evolutionary history.]

@FBADelane @jjlive1 @NeneAura https://t.co/I8JVwbwPv5 The Albert Perry discovery was only made possible because African Americans engage in commercial genetic/ancestry testing at a significantly higher proportion to native Africans. https://t.co/2y3EZ35xz3

@Baluch_98_ I guess so, modern human is believed originated in Africa (probably in Cameroon) and spread throughout rest of world, in accordance to genetic studies Y-chromosomal Adam is an African. https://t.co/QaCwdgRRBT https://t.co/nAqJjl83Jo https://t.co/qxbM9Vawgl
