Unlike other Homo fossils, it had a number of primitive features including a long, apelike face, large teeth, and a tiny braincase about one-third the size of that of a modern human being. This confirmed that, contrary to some conjecture, early hominids did not need big brains to make their way out of Africa.
So, the discovery of Skull 5 alongside the remains of four other hominids at Dmanisi gave the scientists an opportunity to compare and contrast the physical traits of ancestors that apparently lived at the same location around the same time.
In October 2013, after eight years of research, Dr. David Lordkipanidze, a researcher at the Georgian National Museum in Tbilisi and the lead study author, and his colleagues said that the differences between these fossils were no more pronounced than those between any given five modern humans or five chimpanzees. The hominids who left the fossils, they noted, were quite different from one another but still members of one species.
Now it gets controversial, because Dr. Lordkipanidze claimed that the similarities between the new skull from Georgia and Homo erectus remains from Java, Indonesia may mean that there was genetic continuity across large geographic distances. What's more, the Dmanisi researchers suggest that the fossil record of what have been considered different Homo species from this time period, such as Homo Ergaster, Homo Rudolfensis and Homo Habilis, could actually be variations on a single species, Homo erectus. In other words, just as people look different from one another today, so did early hominids look different from one another, and the dissimilarity of the bones they left behind may have fooled scientists into thinking that they came from different species. Thus this new theory defies the current understanding of how early human relatives should be classified.
