Sentinelese Islanders’ isolation duration?

North Sentinel Island is a remote island in the Bay of Bengal, home to the Sentinelese, an isolated indigenous tribe. Little is known about them due to their hostility towards outsiders. They may have been isolated for 60,000 years and survived the 2004 tsunami.

Located in the Bay of Bengal in the Indian Ocean, North Sentinel Island is an isolated island of approximately 28 square miles (72.5 sq km). It is home to the Sentinelese, a small group of indigenous people. There are estimated to be 40 to 250 Sentinelese, but as the tribe has a history of voluntary isolation and has been hostile and violent towards outsiders who have attempted to visit, little is known about them. It is widely believed that the Sentinelese Islanders were largely isolated from the outside world for approximately 60,000 years and are direct descendants of the first humans to leave Africa.

More information on the Sentinelese:

In 1974, a National Geographic film crew attempting to film the Sentinelese was hit by an arrow attack and the director was shot in the leg.
North Sentinel Island is just 25 km from South Andaman Island, but those who live there find the Sentinelese language incomprehensible, indicating the level of isolation of the neighbours.
The 2004 Indian Ocean tsunami directly affected North Sentinel Island. Some believe the tribe survived because they had ancient knowledge of the island’s weather patterns and knew to travel further into the forest.
