Passage
The scientists who discovered the skeleton of "Ardi"-short for Ardipithecus ramidus-think she may
represent a breakthrough in the study of human origins. The fossils show that Ardi walked upright, and that
her teeth resemble modern human teeth more closely than they do those of a chimpanzee. Curiously,
though, her feet were capable of grasping, something chimps need in order to climb in trees. "This is huge,"
says Carol Ward of the University of Missouri. "This is the biggest discovery since the 'Lucy' skeleton of the
1970s."
