Humans Arrived In The Americas 22,000 Years Ago

For over half a century school children have been taught that people first arrived on the American continents around 10,000 to 12,000 years ago.

It looks like that history lesson is about to change. From the New York Times article where I found this...

"Researchers here say they have unearthed stone tools proving that humans reached what is now northeast Brazil as early as 22,000 years ago. Their discovery adds to the growing body of research upending a prevailing belief of 20th-century archaeology in the United States known as the Clovis model, which holds that people first arrived in the Americas from Asia about 13,000 years ago."

What other little "details" do we have wrong? Time to update the "History" books.
