Modern humans, or homo sapiens, most likely emerged between 60,000 and 80,000 years ago in Africa.
They quickly fanned out to Australia and Central Asia about 50,000 years ago and arrived in Europe only about 40,000 years ago.
Many scientists thought humans first ventured into the New World across a land bridge from present-day Russia into Alaska about 13,000 years ago.
This new discovery suggests humans may have crossed the land bridge into the Americas much earlier -- possibly during an ice age -- and rapidly colonized the two continents."It poses some real problems trying to explain how you have people (arriving) in Central Asia almost at the same time as people in the Eastern United States," said Theodore Schurr, anthropology professor at the University of Pennsylvania and a curator at the school's museum."You almost have to hope for instantaneous expansion ...
Although long considered one of Korea's top actors by the local press, this was the first opportunity for Jeon to really shine in an international spotlight.
(CNN) -- Archaeologists say a site in South Carolina may rewrite the history of how the Americas were settled by pushing back the date of human settlement thousands of years.
But their interpretation is already igniting controversy among scientists.
The film itself too was widely praised, and for most Korean critics it represents sort of an obvious choice for the year's best feature.
Two blockbusters punctuated the middle part of the year.
We're talking about a very rapid movement of people around the globe."Schurr said that conclusive evidence of stone tools similar to those in Asia and uncontaminated radiocarbon dating samples are needed to verify that the Topper site is actually 50,000 years old."If dating is confirmed, then it really does have a significant impact on our previous understanding of New World colonization," he said.
