An older human ancestor than Lucy

Yesterday was a big day for anthropology, seeing the first publication of some 15 years worth of analysis of a 4.4 million-year-old fossil skeleton of Ardipithecus Ramidus first discovered by Gen Suwa, then a graduate student of Berkeley paleoanthropologist Tim White, in Ethiopia, in 1992. Science magazine has made all eleven papers freely available to anyone willing to register at their site.
