It's my understanding that fossil evidence for Homo Sapiens only dates back 200,000 years in Africa.
Yet the article talks about our “genetic Adam” being alive as much as 321,000 to 500,000 years ago.
Outside of Africa, it's my understanding that confirmed evidence of Homo Sapiens begins about 70,000 years ago.
And, in Israel and the Caucasus region, there is very recent evidence of Homo Sapiens that might go back 100,000 years ago.
Reread the article.
There are fossils of members of the genus Homo going back much further than 200,000 years. When our species officially begins is a matter of opinion, but Homo sapiens was descended from earlier human species.
