Abstract(s)

It is now rather evident that, concomitant with the advent, growth and disappearance of the traditionally defined Western European Upper Paleolithic techno-complexes, a series of discrete eco-cultural niches would have existed within Iberia. Vale Boi, and its surroundings, may represent one of these niches, since its lengthy and fairly complete archaeological record clearly attests that the region was an attractive location for hunter-gatherer communities for over 10,000 years. From the first Modern Human occupations, c. 32 ka cal BP ago, a set of very specific cultural adaptive markers seem to have been developed in response to the particularities of the regional ecological background. Some of these strategies, such as intensive subsistence practices, raw-material specialized use, among others, were resilient through time and apparently impermeable to the major shifts in the techno-typological novelties brought about with the advent of each Upper Paleolithic phase. Even with the appearance of quite unique and broad-scale technologies, e. g. Solutrean, regional markers and identity have been kept, clearly showing that each level of the adaptive system seem to have operate at its own pace. This paper focus on long-term adaptive choices and on how and why hunter-gatherers inhabiting Vale Boi manage to absorb change and re-organize their system under new techno-complex cultural patterns while still retaining, efficiently, the same regional adaptive idiosyncrasies. Within the theoretical framework of Panarchy and the cross-scale resilience model we argue that cross-scale interactions between creative and conserving niche-specific behavioral adaptations were the keystone for the sustainability of hunter-gatherer cultural systems across the Late Pleistocene. c (C) 2017 Elsevier Ltd and INQUA.
