Long-term cultural continuity across the Neanderthal-modern human sequence at Üçağızlı II Cave, northern Levant

We present evidence from Üçağızlı II Cave in the northern Levant, Türkiye, documenting the sequential occupation by Neanderthals (Homo neanderthalensis; 77-59 ka) and modern humans (Homo sapiens; 59-47 ka). The combined evidence of human fossils, faunal and floral remains, lithics, and manuports demonstrates significant behavioral and technological continuity across this taxonomic sequence, characterized by consistent subsistence strategies and the persistent selection and transport of specific nondietary mollusk shells. The lithic assemblages largely align with late Middle Paleolithic traditions, exhibiting characteristic Mousterian variants. The association of diagnostic human fossils with these archaeological remains demonstrates that the shift from Neanderthals to modern humans occurred within a cultural continuum. Our findings suggest shared behaviors between Neanderthals and modern humans that extended beyond subsistence to include nonutilitarian behaviors within the specific geographic and temporal context studied here.
