The linguistic evidence suggests that stratification structure relating to caste system and slavery likely were shared between the Manding and Soninke people, and possibly some others such as the Dogon people of West Africa. However, the linguistic differences between the caste and slave systems of the Soninke and Manding on one hand and northern ethnic groups of Africa such as the Tuareg people and Moors on the other, suggests that these evolved separately.
