Prehistoric Peopling of the Americas

2008 Sep 3	Oldest Skeleton in Americas Found in Underwater Cave? http://news.nationalgeographic.com/news/2008/09/080903-oldest-skeletons.html “Deep inside an underwater cave in Mexico, archaeologists may have discovered the oldest human skeleton ever found in the Americas. … the female skeleton has been dated at 13,600 years old. If that age is accurate, the skeleton—along with three others found in underwater caves along the Caribbean coast of the Yucatán Peninsula—could provide new clues to how the Americas were first populated. The remains were found some 50 feet (15 meters) below sea level in the caves off Tulum. But at the time Eve of Naharon is believed to have lived there, sea levels were 200 feet (60 meters) lower, and the Yucatán Peninsula was a wide, dry prairie.”

2005 Dec 12	Americas Settled by Two Groups of Early Humans, Study Says http://news.nationalgeographic.com/news/2005/12/1212_051212_humans_americas.html “At least two distinct groups of early humans colonized the Americas, a new study says, reviving the debate about who the first Americans were and when they arrived. Anthropologists Walter Neves and Mark Hubbe studied 81 skulls of early humans from South America and found them to be different from both modern and ancient Native Americans. The 7,500- to 11,000-year-old remains suggest that the oldest settlers of the Americas came from different genetic stock than more recent Native Americans.”
