Abstract

The extent to which the earliest anatomically modern humans in Africa exhibited behavioral and cognitive traits typical of Homo sapiens sapiens 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, thermoluminescence, optically stimulated luminescence, uranium series, and amino acid racemization. Faunal and stratigraphic data are consistent with this age.

摘要

非洲最早的解剖学意义上的现代人类展现出智人特有的行为和认知特征的程度存在争议。在东扎伊尔，有骨制尖器的考古遗址通过几种技术得出的年代早于89（-15）+22千年前。这些技术包括电子自旋共振、热释光、光释光、铀系法和氨基酸消旋作用。动物群和地层数据与这个年代相符。
