Resumo(s)

Marine Isotope Stage (MIS) 3, ranging from around 57,000 to 29,000 years ago, is a period of significant archaeological interest due to notable transitions in lithic technology and hominin populations. In Europe, this time saw the replacement of Middle Palaeolithic (MP) technologies associated with Neanderthals by Upper Palaeolithic (UP) technologies linked to anatomically modern humans (AMHs). This technological shift is conventionally attributed to a demographic turnover; however, the timing of this transition varied regionally. The presence of Neanderthals and AMHs in the Levant, western Europe, and elsewhere over extended periods complicates the narrative, suggesting asynchronous and regionally diverse associations of hominin species and lithic technologies. This study shifts the attention to potential technological and cultural transmissions among MP- and UP-making groups, emphasizing the roles of social and exchange networks. Recent data from the obsidian-rich Armenian Highlands enable us to consider the mobility and land use of these groups without the added complication of toolstone with different knapping qualities, so patterns more clearly reflect mobility patterns, land use strategies, and potential social connections of foraging groups. These results suggest that, while MP-making groups in MIS 3 had overlapping territories, the UP-making groups at Aghitu-3 had smaller movements on the landscape. In contrast, MIS 2 sites with UP lithic assemblages have resource territories that apparently overlapped much like those of the MIS 3 MP sites. The findings hint at the possibility that differing mobility and land use during MIS 3 might have contributed to the coexistence of distinct lithic technologies, potentially through social transmission rather than a direct replacement of hominin populations.
