Early Americans faced rapid late Pleistocene climate change and chaotic environments

[News] The environment encountered when the first people emigrated into the New World was variable and ever-changing, according to a Penn State geologist.

'The New World was not a nice quiet place when humans came,' says Dr. Russell Graham, associate professor of geology and director of the Earth & Mineral Sciences Museum."

Archaeologists agree that by 11,000 years ago, people were spread across North and South America, but evidence is building for an earlier entry into the New World, a date that would put human population of North and South America firmly in the Pleistocene.
