Apologies if this has been posted, I did only check in this forum.
As we all are told, our species migrated out of Africa many moons ago. However recent genetic analysis of the southern African Khoisan tribes revealed that they contain western Eurasian genes. The author of this paper proposed the question and used this evidence as their conclusion.
This migration back into Africa was approximately 3000 years ago, and infact may not be the only time. These genes reveal segments in their DNA with European and Asain origins. However I am unsure if this could be very old DNA, I am no biologist. Regardless, this tribe was previously thought to be purely African ancestry but of the 32 people who were tested every single person had these segments. It is conclusive to me that there must have been some kind of European/Near Eastern migration back into the deep south.

Now any thoughts to why there would be a migration so far south? Were they sea faring or was it land migration? Also is this linked to the collapse of the Bronze Age in anyway?
So many new questions!
Stay frosty ATS
In particular, we also find evidence for two admixture events in the history of Kenyan, Tanzanian, and Ethiopian populations, the earlier of which involved populations related to west Eurasians and which we date to ∼2,700–3,300 y ago.
Raids into the north were launched especially from Novgorod, which was well connected to the Crimea and, from there on, to the Caspian Sea and the slave markets of Central Asia. Raids were done by private warlords and princely troops, and they extended all the way to the coasts of the Gulf of Bothnia and Lapland.

An interesting idea. However these researchers are getting dates by comparing the mutation rate and how far it has come. Giving them a date of 2700 - 3300 years ago.

Could have been due of white slavery .. there are a lot of study about this
I wouldn't be surprised if they found genetic markers that showed 10,000 BCE - 12,000 BCE...when the Ice age is thought to have come to an abrupt conclusion, after the Nrothern hemisphere was bombarded by a series of space borne objects, comets and meteors have been theorised to have peppered the North, and there is evidence worldwide to support the theory.
The result would have been calamity, and would have driven an exodus from the Northern regions, back Southwards.

I don't understand what you mean about not part of an out of Africa thesis?
I was aiming for more questions and discussion about how European DNA found its way into a Southern African tribe at the beginning of the Iron Age.
I was more along the line of thinking that some Europeans migrated back into Africa leaving behind the memory of the Bronze Age in fire.
After the dispersal of modern humans (Homo sapiens) Out of Africa, hominins with a similar morphology to that of present-day humans initiated the gradual demographic expansion into Eurasia. The mitogenome (33-fold coverage) of the Peştera Muierii 1 individual (PM1) from Romania (35 ky cal BP) we present in this article corresponds fully to Homo sapiens, whilst exhibiting a mosaic of morphological features related to both modern humans and Neandertals. We have identified the PM1 mitogenome as a basal haplogroup U6*, not previously found in any ancient or present-day humans. The derived U6 haplotypes are predominantly found in present-day North-Western African populations. Concomitantly, those found in Europe have been attributed to recent gene-flow from North Africa. The presence of the basal haplogroup U6* in South East Europe (Romania) at 35 ky BP confirms a Eurasian origin of the U6 mitochondrial lineage. Consequently, we propose that the PM1 lineage is an offshoot to South East Europe that can be traced to the Early Upper Paleolithic back migration from Western Asia to North Africa, during which the U6 lineage diversified, until the emergence of the present-day U6 African lineages.
