I see now... I am skeptical that it would be possible for the Late Indus valley people (assuming they actually spoke a Dravidian language, or more than one - a very reasonable but not proven assumption) to sail that far en masse (or at all), but at least they were in the position to theoretically do so.Im not talking about the brahui population in Pakistan
In the same way the pakistani brahuis live in isolation , far away from the other dravidians and are genetic closer to balochis than tamils , i was thinking about northern dravidian migration to Madagascar fleeing indo aryan population pressure .
Malagasy have been part of the slave trade since arrival with some being sent back to Indonesia.The malagasy will be part of the slave trade
Will the bantus slowly melt into the malagasy society like otl , or are we gonna see them becoming a fully black serf subculture under the rule of a ruling class of mixed austronesian/dravidian individuals ?
