Here is an interesting hint concerning Basal Eurasians. It appears that there were two
Basal Eurasian lineages. One that did go through the bottleneck and one pre-bottleneck. I'm asking myself what the implications are concerning the back to Africa migration, and how to classify the Basal Eurasian lineage that didn't underwent the bottleneck? Many folks are wondering about the nature of Basal Eurasian, is it a proper Eurasian or rather an African or ANA-like lineage?
What do you think folks?

This type of ancestry includes the “Basal Eurasian” lineage that was previously shown to have admixed into Near Easterners and that is inferred to have descended from same founder event / bottleneck that gave rise to the main ancestry in all non-Africans 19. However, our“deep ancestry” definition also includes deeper splitting lineages as well, some of whose ancestors may not have experienced this bottleneck. Indeed, in what follows we show that “Deep Ancestry” in West Eurasians is comprised not only of Basal Eurasian ancestry but also some more deeply splitting lineages. Dzudzuana is inferred by qpAdm to have ~28% deep ancestry, identical to the admixture graph...
