The research team—from the University of Wisconsin, University of California, Davis, Baylor College of Medicine, Stellenbosch University in South Africa, and McGill University in Quebec—believes that both the Stem1 and Stem2 populations originated in Africa, but not together. It was hundreds of thousands of years, they say—potentially because of some environmental event around 120,000 years ago—before the populations started mixing and two groups merged to really kick off the start of new people groups based in Africa. 6park.com
By comparing DNA from multiple groups of people throughout Africa, and then comparing that DNA to the genomes of people from other ancestry groups, the researchers believe they have found enough solid proof to say that there had to have been a Stem1 and Stem2. The precise locations of the two groups remains unknown, but the distinctly Stem1 or Stem2 DNA seemingly survived and was continuing to influence ancestry as recently as 25,000 years ago.
