摘要

一方面,遗传学观察表明,解剖学意义上的现代人(AMH)在公元前 70-50 千年左右从非洲向欧亚大陆进行了一次基本迁徙,并导致 AMH 散布到世界各地("走出非洲-II "模式)。另一方面,由于迁徙的初始阶段位于非洲东部和东北部,文化特征的考古学模式迄今为止既不支持也不反对在假定的迁徙地区和相关时间内的这一模式。本文探讨了考古记录中迁徙的明显隐蔽性及其原因。我们认为夏季/冬季降雨边界造成了东非和东北非之间的阶段性隔离,阻碍了这些地区之间的文化交流,这可能是文化适应或迁徙造成的。我们排除了大规模的扩散事件,只接受小规模的人口迁移。这或许可以解释为什么迁徙事件在考古学上并不明显。

Cultural rhythms and pulses on MIS 5-3 migration episodes of Homo sapiens dispersal in Northeast Africa
On the one hand, genetic observations suggest one essential migration of anatomically modern humans (AMH) from Africa to Eurasia had taken place around 70-50 ka BP and led to the dispersal of AMH all over the world (Out-of-Africa-II model). On the other hand, given the initial phase of the migration would have been located in East and Northeast Africa, archaeological patterning of cultural traits can, so far, neither support nor contradict such a model within the supposed area of migration, and at the time concerned hereby. This paper addresses the obvious invisibility of the migration in the archaeological record and the reasons for it. We propose the summer/winter rainfall frontier to have caused phases of isolation between East and Northeast Africa, impeding cultural exchange between these areas, either resulting from acculturation or migration. We exclude large scale events of dispersal, only small-scale movements of populations to be admitted. This might explain the lack of archaeological visibility of the migration event.
