Literally, to all of us. Here's the bit:
. . .[The study collected] genomes from 44 modern Nama individuals from southern Africa, an Indigenous population known to carry exceptional levels of genetic diversity compared to other modern groups. . . .
The study model suggests the earliest population split among early humans that is detectable in contemporary populations occurred 120,000 to 135,000 years ago, after two or more weakly genetically differentiated. . . populations had been mixing for hundreds of thousands of years. After the population split, people still migrated between the stem populations, creating a weakly structured stem. This offers a better explanation of genetic variation among individual humans and human groups than do previous models, the authors suggest. . . .
So, back five million years, our mom was Lucy, but our most modern form is probably directly linked -- at about 135,000 years ago, onward. . . to peoples very much akin to what we call the present day Nama, on the borders of South Africa and Namibia.
We all -- all humans -- for a goodly portion of the last 100,000 or so years. . . closely resembled them, even in appearances, in all likelihood. [All of which calls into question. . . the wisdom of mistreating our mothers, as they attempt to come across our southern border. We've only observed the concept of "borders", for a blink of an eye, compared to Nama timeframes. Indeed, consider here, how much more closely the Northern England's "Cheddar Man" -- dated at "only" about 9,000 years ago (see image at link). . . resembles the Nama, than he does. . . the decidedly pale Brits, of today. For almost all of our time here on Earth, we have been. . . brown peoples.] Out, smiling. . . .

Fascinating...the more we look, the more we learn.
Did you see this: https://www.cnn.com/2023/05/15/health/human-dna-captured-from-air-scn/index.html ? Would like to see the peer review paper. Huge implications if true.
Peace~~~in these crazy times

OMG, this is a great find! -- I had NOT seen this. And the legal and ethical issues are. . . simply staggering.
On the one hand, it was only a 280 sq. ft. room -- a small bathroom sized room (not a movie lobby -- but that is probably only a decade away, now). On the other hand, the likelihood of mistaken identities is... vast -- and growing, exponentially!
[Like you, I am kinda' dubious that the actual peer reviewed paper makes as bold a set of claims.] Even so, it is supposedly true that Xi's Chinese state actors have been sequencing Uyghur Muslims for years, for surveillance, or worse. Awful.]
These are indeed. . . difficult times. And yet, the basic bioscience of it all. . . will forever captivate my imagination.
Have a great weekend!
Namaste. . . .
