When Were the Americas Populated?

evil agent passes along an article in Scientific American reporting that new radiocarbon dating techniques have cast doubt on the accepted story of how the Americas were populated. In the traditional view, "[M]igrants out of northeast Asia slipped into the Americas bearing finely shaped stone projectiles, so-called 'Clovis points,' after the town in New Mexico where they were first uncovered. This Clovis culture rapidly spread throughout the empty continents and by 1,000 years after their arrival had reached the southernmost tip of what is now South America, making them the original ancestors of indigenous Americans." The new dating of Clovis sites suggests that "Clovis" was not a people, but rather a technology. That is, a new and more efficient method of making arrowheads for hunting spread rapidly through a pre-existing population in both North and South America, over at most 350 years.

    ...have been around for 100's of thousands of years and they are not stupid. Who is to say that 60000 years ago somebody from Indonesia could not possibly have seen most of the world in a lifetime, if they had so desired? There wouldn't have been any evidence of small scale migration which modern archeologists could find, yet the written history is based only on mass movements of population.

    TFA ends with I think there's enough evidence now to say that there were pre-Clovis people in the Americas."

    Who is to say that it hadn't been happening for several times the 25000 year time scale they are talking about?
