This genome shows African ancestries that existed in the southern reaches of eastern Africa before post African Humid Period (ie drying Green Sahara) migration of 'Sudanese' phenotypes from Tropical North Africa (aka the Sahara) toward the Nile Basin (south and east). In other words it shows the source of northwest bound Africans into early Holocene Tropical North Africa from where Pleistocene aridity never had any effect on continuous African development for over 70,000 years.

8200 BP monsoon maximum Malawi aDNA shows there was 6-way African substructure in southeast Africa at that time. • Khoe • San • Nuba (ie, joint NigerCongoKordofanian & NiloSaharan) • Atlantic West African • East African A (long before any proposed 'Bantu') • East African 'Mota' (almost 4000 years before Mota). Also, there's supposed outside Africa elements, West Eurasian in general • Epigravettian Italy • Neolithic Anatolia in particular. For a little African perspective. Africa, from the Cape north to a line at southern Kenya to South Sudan to Guinea Bissau, was habitable through all time. Note yellow grasslands, purple savanna with trees, and various green scub and forestry.

2600km/1600m of desert separated the grasslands from Taforalt Maghreb to their north for more than 10000 years (uncalibrated 20000 to 11000 years ago).
Sudanese phenotype African folk were in the Maghreb before the Ice Age began.
With the West African Monsoon in full retreat, no oxen, pack-asses, transport beasts of burden, nor travel horses or camels, and no super long term water storage or food prey, attempted vast desert crossings = a 💀 death wish.
'Sudanese' Africa is another story. It was a Grasslands Virtual Paradise during those Ice Ages way up north.
Blombos and Panga ya Saidi are asterisked. Look them up to understand their significance. It's all about continuity and persistence of site occupation and tool cultural development.
Malawi's Hora Girl lived after the mapped timeframe. Her 6-way African substructure ancestry could go back to the West African Monsoon Optimum.

I suspect the ancestries labeled Villabruna and Anatolia actually mark In&Out of Africa genomics that birthed West Eurasians since no archaeology supports movement bucking the tide of East Africans moving north.
Nor is there any incentive for late Pleistocene / early Holocene West Eurasians to laboriously trek for thousands of miles and through unaccustomed great heat to get to Malawi as if they knew it was there waiting.
I'm not considering Quest for Fire fantasies.

The whites' focus on the Sahara and West Eurasians if imbibed will poison minds against the greater overall African reality seen Through Afrikan Eyes.
Which is why the last thing I do is read the white authored published text, if I even bother to read it at all.

elMaestro's 2018 K=13 ADMIXTURE graph, where I'm focusing on the color coded ancestries, allows us to see a time depth for exemplar population type first appearances, over interpretation be damned. Everything above the line is in the Mt Hora Girl, thus in early Holocene Malawi before 8000 years ago ~6400 BCE. Below the line are ancestries that weren't in the southern region of East Africa per Mt Hora Girl's genome. Some of them didn't come into existence until the mid Holocene or even later per this ADMIXTURE pgm run. BIG CAVEAT:All ADMIXTURE program produced graphs will vary pending the input populations. The more samples included from the same locale or region will bias the output as will the number of individuals selected from any given population.

Rearranging and rewording the above table so some things hopefully stick out for clearer cognizance. Color | K Land Region | Locale | Exemplar | Exm Pop Date | 1st Geo Pop | 1st Show Date |

?? hold x G? Waiting....
Doesn't the Tuareg "live" in the desert ..."death wish"?
Grosso et al? Have BOTH phenotypes living in the Green Sahara.
