But again the Rendille are generally believed to be originally from southern ethiopia. Never heard anyone saying the came from southern SomaliaThe Rendille are actually the biggest slam dunk debunking the Southern Ethiopia theory. They can be modelled as Somali from Somalia + Borana Oromo + minorly Samburu. They also have a big % of paternal E-M329 (which is the classical Omotic paternal marker) not found in anybody from Somalia.
The proto-Somali ancestors of the Rendille moved from Southern Somalia into Northern Kenya. Not the other way around.
