Marks on sloth bone suggests earlier North American settlement

The discovery of what appear to be dozens of cut marks on the femur of a gargantuan, 1,300-kilogram Jefferson’s ground sloth is being hailed as the earliest trace of a human presence in the Great Lakes state.
But the find also represents a significant new piece of evidence in support of the theory that the first inhabitants of Canada, the U.S. and the rest of the Americas were not the so-called Clovis people — known from distinctive tools they left at various archeological sites from about 12,600 years ago — but a much earlier wave of Ice Age migrants ancestral to many of today’s New World aboriginal populations.
