NEW YORK (April 11, 2013)--Scientists are gaining new insights into an extinct South African creature that had an intriguing mix of human and ape-like traits.
The creature evidently had a unique way of walking, but scientists still haven't pinned down where the pre-human fits on the human evolutionary family tree.
Australopithecus sediba lived some 2 million years ago, and it climbed through trees and also walked upright.
Its remains were discovered in 2008 when the 9-year-old son of one of the researchers happened to find a bone.
Scientists reported in 2011 that some of the creature's bones showed a combination of human and more ape-like traits.
Now six more papers published Thursday by the journal Science present more examples of that in the teeth, ribs and legs.
