Fark (of all places) linked up news of a new hominid fossil find. This time it's 4.5 million year old Ardipithecus ramidus, thought to be the first hominid species to arise after the chimpanzee-human split. The bad news: not much more than teeth, toes, and fingers. The good news: it's still enough to show they were fully bipedal at the time.
