Despite the numerous studies proposing early human population expansions from Africa into Arabia during the Late Pleistocene, no archaeological sites have yet been discovered in Arabia that resemble a specific African industry, which would indicate demographic exchange across the Red Sea. Here we report the discovery of a buried site and more than 100 new surface scatters in the Dhofar region of Oman belonging to a regionally-specific African lithic industry - the late Nubian Complex - known previously only from the northeast and Horn of Africa during Marine Isotope Stage 5, ∼128,000 to 74,000 years ago. Two optically stimulated luminescence age estimates from the open-air site of Aybut Al Auwal in Oman place the Arabian Nubian Complex at ∼106,000 years ago, providing archaeological evidence for the presence of a distinct northeast African Middle Stone Age technocomplex in southern Arabia sometime in the first half of Marine Isotope Stage 5.

A Nubian complex site from central Arabia: implications for Levallois taxonomy and human dispersals during the upper Pleistocene.

Rémy Crassard; Yamandu Hilbert

Archaeological survey undertaken in central Saudi Arabia has revealed 29 surface sites attributed to the Arabian Middle Paleolithic based on the presence of Levallois blank production methods. Technological analyses on cores retrieved from Al-Kharj 22 have revealed specific reduction modalities used to produce flakes with predetermined shapes. The identified modalities, which are anchored within the greater Levallois concept of core convexity preparation and exploitation, correspond with those utilized during the Middle Stone Age Nubian Complex of northeast Africa and southern Arabia. The discovery of Nubian technology at the Al-Kharj 22 site represents the first appearance of this blank production method in central Arabia. Here we demonstrate how a rigorous use of technological and taxonomic analysis may enable intra-regional comparisons across the Arabian Peninsula. The discovery of Al-Kharj 22 increases the complexity of the Arabian Middle Paleolithic archaeological record and suggests new dynamics of population movements between the southern and central regions of the Peninsula. This study also addresses the dichotomy within Nubian core typology (Types 1 and 2), which was originally defined for African assemblages.

Südarabien während des Spätpleistozäns und Frühholozäns: Archäologie, Paläogenetik und Populationsdynamik

Yamandu Hilbert; Jeffrey I. Rose

Dieser Artikel prasentiert eine Ubersicht zu der gegenwartigen archaologischen und palaogenetischen Forschung in Sudarabien. Neue Ergebnisse mitochondrialer DNS Forschung, die an modernen Populationen aus Dhofar, Sudoman, und der Mahera Provinz, Jemen, gewonnen wurden, werden hier in Kombination mit neuesten archaologischen Forschungsergebnissen prasentiert, um Einblicke in prahistorische Populationsdynamiken zu gewinnen. Zwei gegensatzliche Modelle werden hier vorgestellt, mit denen die Besiedelung der arabischen Halbinsel veranschaulicht werden soll; das „tabula rasa“- und das „Arabian refugia“-Modell. Die gewonnenen Daten, archaologischer und genetischer Natur, unterstutzen die Existenz demographischer Refugien innerhalb des sudarabischen Raumes. Hierdurch wird eine relativ lange Besiedelungszeit Sudarabiens trotz klimatisch unvorteilhafteren Phasen (z.B. Letztes Kalte Maximum – LGM) angenommen. Im Folgenden wird postuliert, dass ein erheblicher Teil des modernen sudarabischen Genpools einer Population zu Grunde liegt, die um 12.000 vor Heute (BP) einen grundlegenden Wachstumsschub und eine subsequente Ausbreitung erlebt hat. Der Ursprung dieser Population wird im Nahen Osten vermutet und ihre Ausbreitung nach Sudarabien wird noch vor den LGM angenommen. Gleichzeitig konnte kein genetischer Nachweis von Populationen alter als 20.000 Jahre erbracht werden, wobei dies als ein Hinweis fur das Aussterben eines wesentlichen Teils des pleistozanen Genpools interpretiert werden kann.
