Ancient omotics were native east Africans. When Cushites began migrating to the east, some started to mix with omotics and nilotics living in east Africa. Omotics most likely borrowed their afro asiatic language from Cushites. So omotics aren't the oldest afro asiatic race because they inherited some the Eurasian DNA they carry from Cushites.
Why do they have the oldest branch if they merely acquired their language from younger Cushitic branches?
