The Andaman Tribes
en.wikipedia.org/wiki/Andamanese_people
The Andamanese people are the various aboriginal inhabitants of the Andaman Islands, a district of India located in the southeastern part of the Bay of Bengal.
The Andamanese resemble other Negrito groups in Southeast Asia. They are pygmies, and are the only modern people outside of certain parts of Sub-Saharan Africa with steatopygia. The Andamanese are believed to be descended from the migrations which, about 60,000 years ago, brought the first modern humans out of Africa to the Andaman Islands. Unlike some Negrito populations of Southeast Asia, Andaman Islanders have been found to have no Denisovan ancestry.
Here is a documentary about them:

There is is a specific tribe called the Sentinelese (North Sentinel Island) who have in fact resisted any newcomers to the island by killing them . DNA analysis of another tribe, the Jarawa, whose members made first contact with the outside world in 1997, suggest that the tribesmen migrated from Africa around 60,000 years ago. However, the researcher in the documentary even says they were comfortable with the out-of-africa theory but then found archaic " white pre-African" chromosomes.
I wonder what we could learn from their genetics and what their true origin is?
