The UP/MP transition and the related MSA/LSA transition in Africa seems to have occurred almost simultaneously and to have coincided with the emergence of modern behavior in other remote parts of the world, as far away as East Timor. The date from Kebara appears a little earlier than the first Aurignacian in Central Europe and Riparo Mochi, and of the LSA in South Africa in Border Cave. Whether transmission of new behavioral innovations was cultural or genetic, an origin in a crossroads region between Europe, Africa, and East Asia, would make fairly good sense.

New radiocarbon dating of the transition from the Middle to the Upper Paleolithic in Kebara Cave, Israel
N.R. Rebollo et al.
The Middle to Upper Paleolithic transition (MP-UP transition) is considered a major technological and cultural threshold, at the time when modern humans spread “out of Africa”, expanded from the Levant into Europe and possibly into central and northern Asia. The dating of this techno-cultural transition has proved to be extremely difficult because it occurred sometime before 40,000 radiocarbon years before present (14C years BP), which is close to the end of the effective dating range of radiocarbon. Other dating methods such as Thermoluminescence (TL) or Electron Spin Resonance (ESR) are not sufficiently precise to date the recorded archaeological MP-UP transition in the Levant. Here we report a consistent set of stratified radiocarbon ages on freshly excavated charcoal from Kebara Cave, Mt. Carmel (Israel), that span the late Middle Paleolithic (MP) and Early Upper Paleolithic (EUP) This study applied novel strategies to improve sample preparation techniques and data analysis to obtain high-resolution radiocarbon models. From this study it is proposed that the MP-UP transition for this site can be placed immediately after 45,200 ± 700 14C years BP and before 43,600 ± 600 14C years BP or from 49/48 to 47/46 radiocarbon calibrated years before present (years Cal BP).
