Akademika Lavrentieva 17, Novosibirsk, 630090, Russia E-mail: [email protected] The Middle Paleolithic of Arabia* The study focuses on the origin and evolution of the Middle Paleolithic in the Arabian Peninsula, a major crossroads of human and animal migrations connecting Africa with Eurasia in the Late Middle and Early Late Pleistocene. Middle Paleolithic human dispersal in Arabia was caused by intermittent environmental changes and related fl uctuations of the Bab-el-Mandeb level. A key role in the African Middle Paleolithic was played by Afro-Arabian Nubian lithic industries showing characteristic Levallois features and associated with anatomically modern humans who had migrated from Africa. Arabian fi nds are discussed with reference to the Out-of-Africa and Multiregional models of human evolution. Based on the totality of cranial, archaeological, and paleogenetic data, it is proposed that modern humankind emerged from an admixture of at least four related taxa, which had evolved in Africa and Eurasia. A hypothesis about the migration of Homo sapiens from Africa across Arabia to Southeast Asia and Sahul 70–50 ka BP is discussed.

Moving between Africa would dry out, or large areas of ground with small and Eurasia would become hampered owing to the rise channels, passable for human and animal migrations, of the sea level, when the Bab-el-Mandeb would become a serious obstacle. *Supported by the Russian Science Foundation (Project According to its natural environment, Arabia belongs No. 14-50-00036). to the Saharo-Arabian phytogeographic region.

After 115 ka Arabia largely depended on sea level changes. When BP, when Arabia and the Levant had the most favorable the sea level was lower, significant areas of coastal environmental conditions for vegetation, the Sahara plains would emerge in Arabia and become inhabited and all of North Africa experienced a period of strong by humans. A reverse process would occur when the aridization (Drake, Breeze, Parker, 2013). In MIS 5.2 sea level would rise: the sea would swallow the coastal (100–90 ka BP), Arabia also underwent considerable areas, including those where Paleolithic sites used to aridization (Preusser, 2009).

Therefore, the sites that emerged during (55–50 ka BP), conditions for human habitation in the regression of the sea are presently not available Arabia slightly improved, as is evidenced by the sites in for archaeological study. As it was mentioned above, the area of Wadi Surdud in the western part (Delagnes the periods of warming and increased humidity were et al., 2012) and Jebel Faya 1 (the upper cultural layers) favorable for the movement of people from Africa to in the eastern part of the Peninsula (Armitage et al., Arabia and within Arabia, but at the same time, the 2011).
