Four years ago archeologists Alison Brooks and John Yellen discovered what might be the earliest traces of modern human culture in the world. The only trouble is, nobody believes them. Sometimes they can’t quite believe it themselves.
Their discovery came on a sun-soaked hillside called Katanda, in a remote corner of Zaire near the Ugandan border. Thirty yards below, the Semliki River runs so clear and cool the submerged hippos look like giant lumps of jade. But in the excavation itself, the heat is enough to make anyone doubt his eyes.
Katanda is a long way from the plains of Ice Age Europe, which archeologists have long believed to be the setting for the first appearance of truly modern culture: the flourish of new tool technologies, art, and body ornamentation known as the Upper Paleolithic, which began about 40,000 years ago. For several years Brooks, an archeologist at George Washington University, had been pursuing the heretical hypothesis that humans in Africa had invented sophisticated technologies even earlier, while their European counterparts were still getting by with the same sorts of tools they’d been using for hundreds of thousands of years. If conclusive evidence hadn’t turned up, it was only because nobody had really bothered to look for it.
In France alone there must be three hundred well-excavated sites dating from the period we call the Middle Paleolithic, Brooks says. In Africa there are barely two dozen on the whole continent.
One of those two dozen is Katanda. On an afternoon in 1988 John Yellen--archeology program director at the National Science Foundation and Brooks’s husband--was digging in a densely packed litter of giant catfish bones, river stones, and Middle Paleolithic stone tools. From the rubble he extricated a beautifully crafted, fossilized bone harpoon point. Eventually two more whole points and fragments of five others turned up, all of them elaborately barbed and polished. A few feet away, the scientists uncovered pieces of an equally well crafted daggerlike tool. In design and workmanship the harpoons were not unlike those at the very end of the Upper Paleolithic, some 14,000 years ago. But there was one important difference. Brooks and Yellen believe the deposits John was standing in were at least five times that old. To put this in perspective, imagine discovering a prototypical Pontiac in Leonardo da Vinci’s attic.
