Let's talk about the SentineleseSentinelese are a tribe that live in North Sentinel island of Andaman islands. This tribe has had no contact with civilisation for approximately 30,000 years. They are said to be extremely violent to the intruders. Many times Sentinelese aimed their arrows at passing helicopters. They have shot down lost fishermen who happened to drift into their territory. We know very little of their culture and the island in which they live is conserved by Indian government. We are not supposed to come closer than 3 km from the island shore. In November 2018 John Allen Shau was killed by some Sentinelese as he tried to "declare Jesus" to them. This incident made Sentinelese a hot topic once again because last I heard about them was in 2004 as a child.
But here's the thing. According to many surveys and studies, Sentinelese do not make fire. They have many similarities between the Jarawa and Onge tribes of Andaman. Although all three of these were initially hostile, now many Onge and Jarawa have dropped violent attacks towards foreigners.
Here's the thing. Neither of these tribes were reported to have known the art of making fire. Modern humans migrated from Africa in waves. The Sentinelse and other above mentioned tribes are said to have come from Africa in canoes here. Sentinelese are known to bury their dead. The tribe's men and women never wear a clothing of any sort.
So here is what disturbs me. Even human ancestors such as Homo Erectus could use fire. Many Southeast Asian tribes with who Sentinelese are grouped together can use fire too. Sentinelese can make tools, weapons, care for ill and bury their dead. They can even make boats that can row in shallow water. Could they have accomplished all of this without fire? That being said Sentinelese are said to preserve the fire that they collect from other sources. This means they know the usage but not the art of making fire. Their population amounts only to a couple hundreds.
But they are by no means primitive or barbaric. They make good use of things that wash out on shores. Plastic bags for carry things. Iron pieces as arrow tips. Coconuts and bananas given by foreigners. We can clearly see evolution at work here.
