...split between apes and humans. "We're in the ballpark. Five or 10 years ago, we couldn't even have conceived of this," asserts White. "Ardipithecus is the closest thing we currently have to the common ancestor of African apes and humans, but its derived characteristics, particularly its teeth, suggest that it postdates that ancestor...
...ancestor, White hints that his team has already discovered hominid fossils that are more than 5 million years old, though he refuses to elaborate before detailed studies are completed. But Leakey and Walker readily acknowledge that they are studying two 5.5 million-year-old hominid teeth and a similarly ancient jaw fragment with an embedded tooth from a site in northern Kenya. "They look like australopithecines with lots of primitive features," Walker says, but there isn't enough evidence from these fossils alone to claim a new species...
...made another dramatic announcement. A fragmentary skull found near Bouri, an Ethiopian village in the Middle Awash region northeast of Addis Ababa, could well be from the missing australopithecine that sired the human race (see cover photo). Excavated in 1997, its jutting face and upper jaw filled with large teeth clearly belong to a species more advanced than A. afarensis yet more primitive than the earliest humans...
...characteristics wasn't precisely what the experts expected--they were looking to see smaller, more specialized teeth and a larger braincase. So they named their hominid Australopithecus garhi (garhi means surprise in Afar). But the skull's intermediate anatomy and its age--about 2.5 million years--put it midway in both time and form between the most recent A. afarensis and the oldest known fossils of our own genus...
...cloth, wrap them in cellophane, dump them in the Mariana Trench--you could plug your ears with a Walkman and crank up a Def Leppard CD to 10--and still you'd hear the little tinny yap-yap of some office seeker promising cleaner streets, safer subways, cavity-free teeth. There was no end to the talking. It was inescapable, depressing, mind numbing. Those were the days! Now it's worse, much worse. Now they listen...
