The earliest-known human ancestors to migrate out of Africa possessed a surprising mix of human-like and primitive features, according to scientists who studied remains dug up at a fossil-rich site in the former Soviet republic of Georgia. Writing on Wednesday in the journal Nature, the scientists described remains of three adults and one adolescent dating from about 1.77 million years ago, excavated at Dmanisi, about 55 miles southwest of the Georgian capital, Tbilisi. The remains shed light on a little-understood but critical period in human evolution -- the transition from the more ape-like creatures known as australopithecines to the genus Homo, of which modern humans are a member. The spines and lower limbs found at the Dmanisi site appear very much like modern humans, suggesting these individuals, which walked fully upright, were highly capable of long-distance treks, the researchers said. But other aspects of the skeletons had more archaic characteristics. The arms were more like australopithecines than people, and the primitive skulls encased relatively small brains. Their simple stone tools also are less advanced than one might have expected, the researchers said. They described the remains as a surprising mosaic of primitive and modern features. These are the earliest humans found outside of Africa. This is the time when our genus spread outside of Africa, David Lordkipanidze of the Georgian National Museum, who led the research, said in a telephone interview. Their heads are primitive. Their legs are very human-like.
Scientists had previously described skulls found at the site, but in recent years found far more extensive remains of the skeletons of these creatures, giving them a more detailed understanding of these denizens of early human history.
