schwit1 shares a report from Seeker: An ice-free corridor between the Americas and Asia opened up about 12, 500 years ago, allowing humans to cross over the Bering land bridge to settle what is now the United States and places beyond to the south. History books have conveyed that information for years to explain how the Americas were supposedly first settled by people, such as those from the Clovis culture. At least one part of the Americas was already occupied by humans before that time, however, says new research on the skeleton of a male youth found in Chan Hol cave near Tulum, Mexico. Dubbed the Young Man of Chan Hol, the remains date to 13, 000 years ago, according to a paper published in the journal PLOS ONE. How he arrived at the location remains a great mystery given the timing and the fact that Mexico is well over 4, 000 miles away from the Bering land crossing. For the new study, Gonzalez, Stinnesbeck, and their colleagues dated the Young Man of Chan Hol’s remains by analyzing the bones’ uranium, carbon, and oxygen isotopes, which were also found in stalagmite that had grown through the pelvic bone. The scientists believe that the resulting age of 13, 000 years could apply to at least two other skeletons found in caves around Tulum: a teenage female named Naia and a 25-30-year-old female named Eve of Naharon. Gonzalez said that the shape of the skulls suggests that Eve and the others “have more of an affinity with people from Southeast Asia.” He and his team further speculated that the individuals could have originated in Indonesia.
