Abstract
The extent to which the earliest anatomically modern humans in Africa exhibited behavioral and cognitive traits typical of Home sapiens sapi ens is controversial. In eastern Zaire, archaeological sites with bone points have yielded dates older than 89(-15)(+22) thousand years ago by several techniques. These include electron spin resonance, thermolu minescence, optically stimulated luminescence, uranium series, and ami no acid racemization. Faunal and stratigraphic data are consistent wit h this age.
