DNA Traces Our Path to One Migration from Africa


The headline is a bad headline. I've heard that the person who writes the headlines is frequently not the author.


The article is about strong evidence that the splitting off of the human tree might have happened much earlier than            previously thought (50,000 years ago). DNA from persons in Papua New Guinea carry 2 percent of their DNA that is much older than 50,000 years. It must be from a group that left much earlier - 140,000 years ago, and then vanished. (Dr. Metspalu. Cambridge U)


Another splitting from the main tree occurred within Africa with the isolated members of the KhoiSan in Namibia. (Dr. David Reich, geneticist at Harvard Medical School).


Apparently DNA samples are challenging the idea that all tracing of DNA shows one migration from Africa.


Splitting occurs, and groups die out.

The DNA from one, or both of the 11,000 and 12,000 year old female skeletons found in Tulum cenotes might suggest if they were from a group that survived and became the Maya, or not. With the bones of Naia, they have a tooth.
