It’s been incredibly influential, causing continuous adaptation as the ‘green belt’ moved north and south. Especially once (~5M ybp) the med flooded. Even then the arabian peninsula and the persian gulf we green, and the gulf rivers produced wetlands similar to those at the origin of the Euphrates that we recognize as so successfully serving the early temple civs like G.Tepe.
Anyway, just trying to help. Gene flow was consistent and I suspect we’ll find it was more influential than we’d thought, and it might just be true that in-migration to the rift valley brought some good genes with it. But we’re still stuck with the 100K bc northern attempt out africa that failed, and the 80-60k crossing of the mouth of the red sea that seems to have produced the majority of the coastal migrations.
Hugs. Love you man. Keep up the great work.
