PRIMATE ABILITIES:
Chimps in the Wild Show Stirrings of Culture
Gretchen Vogel
TAÏ NATIONAL FOREST, CÔTE D'IVOIRE, WEST AFRICA--Our closest primate relatives exhibit traditions of grooming, calling, and tool use that a growing number of researchers say add up to a primitive form of culture. Their argument rests on examples in which one chimp learns from another, and on the seemingly arbitrary differences in habits between chimpanzee groups at different sites. But some researchers argue that our primate cousins do not learn as we do, by imitation and instruction, and most agree that primates don't seem to be able to build on previous inventions as humans do.
