Puzzle du Jour

Recent finds from the caves of China. Fascinating possibilities:

Last week, an international group of researchers reported the discovery of fossils belonging to a strange population of hominids that lived in southwestern China as recently as 11,500 years ago, at the end of the Pleistocene Epoch. The fossils resemble modern humans in many ways but possess some unusual characteristics. The traits may be evidence that Homo sapiens were more diverse in the past—or a sign that scientists have uncovered a new species.

By 11,500 years ago, humanity was already well established in the Americas. That's really recent.
