An interesting preliminary study of a broad range of people from purely genetic information that is raising big questions regarding the dates of early human movements. These variations often differ from recorded physical studies (sometimes with very large margins) and will need further investigation but they do indicate important areas for this research.

>>Researchers using modern and ancient genomes have created the largest human family tree ever made, reports Jack Guy of CNN.

An international team of scientists combined genetic reports of 3,609 individual genome sequences from 215 populations around the globe to produce a massive family tree that identifies nearly 27 million ancestors and where they lived, per U.S. News and World Report.

“We have a single genealogy that traces the ancestry of all of humanity and shows how we’re all related to each other today,” Anthony Wilder Wohns, leader of a new study published in the journal Science, tells CNN.

Wohns, a postdoctoral researcher at the Broad Institute of MIT and Harvard University in Cambridge, Mass., states the study uses ancient genomes from samples dating from more than 100,000 years ago.

“We can then estimate when and where these ancestors lived,” he says in a statement. “The power of our approach is that it makes very few assumptions about the underlying data and can also include both modern and ancient DNA samples.”<<

I’ve watched this video a dozen times now. Looks interesting.
1. All out of North East Africa about 2 million years ago. So far so good.
2. A small group rapidly migrated to New Guinea area! Is this the Denisovan connection in the Pacific Islanders? Or the Flores Hobbits descended from H erectus?
3. The Americans came down from the North Pole starting 60,000 years ago, but it’s not clear from the video whether that was by way of Greenland or Siberia. In South America by 55,000 years ago. Those dates are both a long way pre-Clovis.
4. The migration from China to New Guinea trickled across from 160,000 to about 50,000 years ago, connection to Australia tenuous even 50,000 years ago (not enough data from Australia).
