Pretty cool.
"“You can now look at the oldest sites and say, ‘We know they were there during the Last Glacial Maximum,’ so maybe some of these oldest sites are also reliable,” he said.
The term “Last Glacial Maximum” is how scientists refer to the height of the last ice age, about 20,000 to 26,000 years ago.
It has long been debated whether humans arrived in the Americas by a northern route from Siberia before or after the Last Glacial Maximum, when vast sheets of ice would have made migration along the Pacific Coast or through western Canada impossible."
The 'last ice age' is also a guess. So is any story about a land migration from Siberia (remember there was a huge ice sheet and glaciers in the way, according to the same sources!).
