They had genetic diversity, probably more than any other tribe. If you were a 19 year old Spanish girl, captured by the Comanche, bad deal. You would be gang raped night after night, and back at the main camp the squaws might burn your nose off. Or cut off one of your ears. You had no rights.
But a captured 5 year old girl or boy was a different matter. Many times Comanche would adopt them into the tribe. The girl would be engaged to a warrior, the boy would become a warrior. These adopted captives had full rights as a Comanche citizen.
Over the centuries the Comanche adopted thousands of Apache, Spanish, and Anglo American children. In many Indian tribes only native born Indians could be full fledged members of the tribe.
The Comanche had massive genetic diversity.
The mother of Chief Quanah Parker was a white girl.
