Seven of his finished hominid busts will be featured at the National Museum of Natural History’s David H. Koch Hall of Human Origins, which opens March 17. They are perhaps the best-researched renderings of their kind." Abigail Tucker, "A Closer Look at Evolutionary Faces", Smithsonian.com, February 25, 2010
4 Years Ago: "Stunning Skull Gives a Fresh Portrait of Early Humans" Ann Gibbons @evolutionscribe @sciencemagazine
"...But what species of Homo is it? Some fossils previously discovered at Dmanisi seemed to have links to H. erectus. But when the big lower jaw was found in 2000, some researchers suggested it belonged to a new species they called Homo georgicus.
With the discovery of the new, fifth skull, the researchers had to confront head-on the variation among all five. Age and sex probably account for much of it: The skulls are thought to have belonged to an elderly toothless male, two mature males, a young female, and an adolescent of unknown sex.
This broad sample from one place and a short span of time is what makes Dmanisi an "exceptional site," White says. By analyzing the skull shapes with 3D computer-based methods, the researchers found that the range of variation in the group at Dmanisi was no greater than within living humans or chimps. The team concluded that all five skulls belong to a single, variable species
Putting all five skulls into a single species still left the problem of what to call it. The team squabbled at first. Looking at particular traits, they found that the upper jaw of Skull 5 most closely resembles the oldest fossil proposed as Homo—a 2.3-million-year-old jaw from Ethiopia tentatively assigned to H. habilis. But Skull 5 also shares key features with H. erectus, such as thick brow ridges. In the end, the team settled on the cumbersome moniker of Homo erectus ergaster georgicus, which recognizes the skull as an earlier Georgian form of H. erectus. But they all prefer to call their finds "early Homo."..."
