How hunter-gatherer tribes survived the 2004 tsunami

In this current period of rapid globalization, the rise of technically advanced societies is unprecedented. This particular period of technological growth is rapid and very noticeable. It’s strange to think that the large scale public Internet as we know it today is a very recent development. I was baby-sitting for a friend’s 10-year old the other day and was helping him do a report on owls. He had found some good websites as source material and I felt like saying in a mocking elderly voice “back in the good ol’ days (I was his age 15 years ago), we walked barefoot in the snow, uphill both ways to library to lift a heavy Encyclopedia Britannica off the shelf to take notes on index cards.”

While I wax nostalgic about the “primitive” pre-Wikipedia days of Encyclopedia Britannica, there are still parts of this world where humans still live a hunter-gatherer lifestyle. In the midst of the tragic news coming out of Southeast Asia after the massive December 2004 Indian Ocean tsunami, I remembered hearing a fascinating story about the Indian Air Force running helicopter sorties to survey the tsumani’s impact on numerous small islands in the Indian Ocean.

One of the islands the Indian Air Force checked on was the North Sentinel Island. When the helicopter came in for closer look, the inhabitants of the island attempted to shoot down the helicopters…with arrows. These inhabitants, known simply as the Sentinelese (nobody has been to figure out what they call themselves), are among the last remaining groups on the planet that have maintained complete isolation from the outside world and modern day technology.

This complete isolation is hard to believe in the 21st century, but every attempt to establish contact in the past has been met with fierce resistant thanks to the Sentinelese skill with the bow and arrow along with a overwhelming amount of courage and fearlessness. This unblinking foreign policy position has probably been maintained for thousands of years. Maybe even longer since the Sentinelese are part of the Negrito tribes that are believed to have arrived to the Great Andaman archipelago 30,000-60,000 years ago. DNA evidence has shown that they may be descendants of the earliest humans to migrate out of Africa.

At least for the time being, they will stay “frozen in time” because the Indian government has decided to simply leave them alone. In fact, the Indian Navy even runs patrols to make sure fisherman and curious tourists don’t venture into the 5 kilometer (~3 miles) buffer zone around the island.

Due to the scope of the 2004 tsunami, it was feared that even with these protections the Sentinelese could have been wiped out. The vigorous response to the helicopters showed otherwise. An interesting theory explaining their survival is 60,000 years of experience may have taught them to move inland when they feel earthquakes. Also, the hunter-gatherer lifestyle leads to a deep understanding of the environment and animals. Since many animals show behavior changes before storms and earthquakes, this have tipped them off to the situation even before sophisticated tsunami warning systems would have.

Stay tuned for more about the fascinating story of the Sentinelese.
