A new generation of archaeologists is searching for new evidence of the earliest humans in America, and finding it. At the annual meeting of the Society for American Archaeology, young researchers reported the discovery and analyses of a number of new sites, especially in South America, where they discovered the bones, stone tools, and hearths of Paleoindians. New dates on those sites show that Paleoindians had spread throughout the Americas by 12,000 to almost 15,000 years ago and even inhabited extreme environments, such as mountaintops or deserts.
