- Analysis of the shape of the braincase of seven-million-year-old Sahelanthropus tchadensis from Chad supports the claim that it is the oldest human ancestor on record.
- The femur of Orrorin tugenensis, a putative human ancestor that lived six million years ago in Kenya, has a shape that is intermediate between that of fossil apes and early members of the human lineage—a finding that confirms previous claims thatthe creature walked upright.
- Tiny, rarely preserved middle-ear bones from two of our ancient relatives that lived millions of years ago exhibit modern features, which may indicate an early shift in hearing ability.
- The latest round of studies of Australopithecus sediba, a nearly two-million-year-old relative of ours from South Africa, reveals a previously unknown form of upright walking and decidedly humanlike jaws and teeth. But is it the ancestor of our genus, Homo? Not so fast.
