No seriously, breathe a sigh of relief -- it's "Ardi" as in Ardipithecus ramidus, not "Artie" as "Artie Lang." After months of rumors, the official word has finally broken out of the University of California at Berkeley's Human Evolution Research Center, and everyone's going ga-ga over this 4.4-million-year-old hominid, according to Discovery News.
Of course, it's important to stress that the archaeological find itself dates back to 1992. That's when anthropologists discovered the first of the remains in the Middle Awash region of Ethiopia. The specimen seemed to offer a little bit of chimp and a little bit of man, standing about 4 feet (1.2 meters) tall, weighing 120 pounds and displaying equal abilities for tree climbing and walking upright. Ardi brings anthropologists ever closer to their Holy Grail: nailing down the last common ancestor between humans and chimpanzees before the two went their separate evolutionary ways.
We're talking a vital point in the ascension of man here. While the actual split between hominid and panin/chimp lines probably occurred some 5.4 million years ago, the 4.4-million-year-old Ardi is as close to the mark as we've managed to hit. The famous Lucy, for instance, was a mere 3.2 million years old.
