First Americans
Archeologist Ben Potter had found two 11,500-year-old skeletons that allowed scientists to determine the point in history when the ancestors of all Native Americans became a distinct group. He found that the girls – who had been cremated in a ceremony following their natural deaths – had been laid to rest close to what used to be a land bridge that joined today’s Alaska with what is now Siberia. This meant Potter had been able to work out where the first inhabitants of North America really came from.
