The Famous Bering Land Bridge Was More Like a Swamp, Geologists Say

Why did some species, including ancient humans, cross the Bering Land Bridge between modern-day Siberia and Alaska during the last Ice Age? The picture has only gotten more complex.

#FossilFootprints date back to between 21,000 and 23,000 years ago, upending previous theory that humans reached continent much later.

Previously, it was believed that humans did not reach the #Americas until a few thousand years before rising sea levels covered the #BeringLandBridge between #Russia and #Alaska, perhaps about 15,000 years ago.

The Bering Land Bridge connecting Asia to North America did not emerge until around 35,700 years ago, less than 10,000 years before the height of the last ice age. Growth of the ice sheets—and the resulting drop in sea level—occurred surprisingly quickly and much later than previous studies had suggested.

Bering Land Bridge formed surprisingly late during last ice age, study finds

A new study that reconstructs the history of sea level at the Bering Strait shows that the Bering Land Bridge connecting Asia to North America did not emerge until around 35,700 years ago, less than 10,000 years before the height of the last ice age (known as the Last Glacial Maximum).
