Were these mota people completely African or did they have Eurasian as well? If I'm not mistaken they were omotic like and omotic is afroasiatic by language and omotic speakers have some traces of Eurasian sometimes quite a lot like wolaytasThey are bored and making up new hypothesis. We just need to have more ancient samples from the Nile Valley and the Horn to learn more. Playing around with old samples like Mota, Dinka, Natufian etc won’t help. They are being amateurish to be honest.
Yes it’s believed the Mota group was concentrated in the southwestern part of Ethiopia. This is why us Somalis have hardly any of it. But then again Mota like ancestery was found to have been up north during the Mesolithic period in Egypt. Stuff is complicated but we need more ancient samples pre Neolithic to get real understanding
