I think this is a load of crap. According to u the famines did NOT alter the fabric of society, the european invasion didn`t and the only reason was the Muhammedan invsaions!!! This looks like a make fit hypothesis rather than a logical one. Going by your assumption the adamanese tribes should be thoroughly developed because they trace their ancestry directly to the Africans and trust me there continuity has not been altered by Famine, European, Muhammedan or Hindu invasions so why are they still un-21st century like(for lack of proper word)? Is it because in this case the Muhammedan's didn`t invade them? It was foolish of you to try to fit in a hypothesis were none existed.
