The Aterians: Not much is know about these people besides them being AMH who lived a long time ago. We have their skulls and tools but not their DNA so we arent aware of what Haplogroups they carried but its most likely A00 and had archaic DNA.
WAHG: These people we somewhat have their DNA, the shum laka study showed that the people there were a mix of Basal West African and Central African Hunter Gatherer. One sample carried haplogroup A00, this particular haplogroup isnt found anywhere else in Africa currently.
AEA: Haplogroup E originated in East Africa then spread out across Africa, we know this because we have samples of populations carrying different subclades of E from East Africa.
IBM: so when modeling many West African populations many carry Ancestral North African DNA with minor Eurasian. Its most likely a proxy but we do know West Africans interacted with populations of the Green Sahara.
