It seems in the past couple years, scientists keep finding new artifacts that shake our current understanding of our roots. We live in a fascinating time!

>That does not mean that this person contributed to the DNA of anyone living today, he added. It is possible that the jawbone belonged to a previously unknown population of Homo sapiens that departed Africa and then died off.

As far as I can tell, the entire "Out of Africa" model taken for granted within the MSM is being treated with increasing skepticism/nuance by scientists actually studying the facts on the ground, leading to these odd & increasingly ancient "first modern out of Africa" stories which may be confusing the public more than they're illuminating the history of human populations.

Razib Khan had a good short primer on this topic a little while back [1], excerpt:

The data for non-Africans is rather unequivocal. The vast majority of (>90%) of the ancestry of non-Africans seems to go back to a small number of common ancestors ~60,000 years ago. Perhaps in the range of ~1,000 individuals. These individuals seem to be a node within a phylogenetic tree where all the other branches are occupied by African populations. Between this period and ~15,000 years ago these non-Africans underwent a massive range expansion, until modern humans were present on all continents except Antarctica. Additionally, after the Holocene some of these non-African groups also experienced huge population growth due to intensive agricultural practice.

To give a sense of what I’m getting at, the bottleneck and common ancestry of non-Africans goes back ~60,000 years, but the shared ancestry of Khoisan peoples and non-Khoisan peoples goes back ~150,000-200,000 years. A major lacunae of the current discussion is that often the dynamics which characterize non-Africans are assumed to be applicable to Africans. But they are not.

As far as I know the scientific consensus is still on the Out of Africa theory.

Melanated people (aka Africans, which is a European term) were the first Hebrews and Arabs. "Africans" who migrated East to China, then back migrated after they went through mutation, and mixed with the original people. But of course, no one would believe it unless, well, you already know. Hopefully all the "pseudo-scholars" who spread this knowledge can rest easy now. Most of them died broke while these "discoverers" will die wealthy and famous. Of my post is perceived as racist, so what. I didn't hurt nothing but feelings.

You can read John Hawks, quoted in this post's linked NYT article, with his own take on recent findings[1], echoing many of the points made by Razib Khan. Even Chris Stringer, one of most vocal & staunch advocates for a simple Out of Africa has recently walked that back [2]

If you are reading experts still standing behind a simplistic Out of Africa model after all the recent findings of archaic admixture and incredibly deep splits in human populations, I'd be very curious to see some links to papers/articles.

200,000 years is still very recent. 2 million years ago we where limited to Africa. After that things get complicated: https://en.wikipedia.org/wiki/Homo_erectus#/media/File:Human...

And of course on these time scales people can easily walk all over the place. We only see remnants of larger populations lone wanderers are extremely unlikely to leave any evidence behind.
