New Timeline for Modern Humans’ Arrival in Indonesia

UNITED NEWS INTERNATIONAL (UNI) — The first modern humans may have arrived in Indonesia thousands and maybe tens of thousands of years before previously thought.

Researchers reanalyzed ancient teeth discovered in the Lida Ajer cave on the island of Sumatra in the late 19th century.

They published their findings Aug. 9 in the science journal Nature.

The new fossil analysis dates the teeth to between 63,000 and 73,000 years old.

The teeth are also the earliest example of modern humans living in the rainforest, which one scientist told Newsweek, requires “technological innovations and sophisticated hunting techniques for survival.”

The new findings come just weeks after another study suggested modern humans were in Australia thousands of years earlier than previously thought.

Both studies challenge the widely held timeline that tracks when modern humans left Africa and started migrating to other continents.
