Human mobility and migration are thought to have played essential roles in the consolidation and expansion of sedentary villages, long-distance exchanges and transmission of ideas and practices during the Neolithic transition of the Near East. Few isotopic studies of human remains dating to this early complex transition offer direct evidence of mobility and migration. The aim of this study is to identify first-generation non-local individuals from Natufian to Pre-Pottery Neolithic C periods to explore the scope of human mobility and migration during the Neolithic transition in the Southern Levant, an area that is central to this historical process. The study adopted a multi-approach resorting to strontium (87Sr/86Sr), oxygen (δ18OVSMOW) and carbon (δ13C) isotope ratio analyses of tooth enamel of 67 human individuals from five sites in Jordan, Syria, and Israel. The isotope ratios point both to a significant level of human migration and/or mobility in the Final Natufian which is compatible with early sedentarism and seasonal mobility and with population aggregation in early sedentary hamlets. The current findings, in turn, offer evidence that most individuals dating to the Pre-Pottery Neolithic were local to their respective settlements despite certain evidence of non-locals. Interestingly, isotopic data suggest that two possible non-local individuals benefitted from particular burial practices. The results underscore a decrease in human mobility and migration as farming became increasingly dominant among the subsistence strategies throughout the Neolithic transition of the Southern Levant.
Tall Abu al-Kharaz, a twelve hectare-large tell in the central Jordan Valley, was occupied for approximately five millennia. In earlier excavation seasons most of the early Iron Age remains were found to have been disturbed by later settlers. Between 2009 and 2012 excavations revealed an extremely well-preserved city quarter dating from around 1100 BC, which represents an essential part of the settlement history of this city. The stone-built architectural compound consists of 21 rooms, with walls still standing to a height of more than 2 m. The inventories of these rooms, which comprised more than 200 complete vessels and other objects, were remarkably intact. Amongst the finds were imports from Egypt and Phoenicia. There were also finds which are associated with the culture of the Sea Peoples/Philistines, such as several Aegean and Cypriote-style vessels and other objects. The find context points to a hasty abandonment of the city. In the past, the beginning of the Iron Age has often been referred to as “the Dark Ages”, a period of cultural regression: this categorization is not appropriate to the find situation at Tall Abu al-Kharaz where the remains of a wealthy society, with far-reaching intercultural connections, can be identified.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
