Going All to Species

ENCORE Meet your new relatives.   The fossilized bones of Homo naledi are unique for their sheer number, but they may also be fill a special slot in our ancestry: the first of our genus Homo.   Sporting modern hands and feet but only a tiny brain, this creature may link us and our ape-like ancestors.   

Some anthropologists hail the discovery as that of a new hominid species.  Not all their colleagues agree.  Find out what’s at stake in the debate. 

Also, the scientist who helped retrieve the fossils describes her perilous crawl through a cave with only ten inches of elbow room.  And a radical theory about what these old bones might mean: could they be from a burial two million years ago?
