Introduction
Across the Mediterranean basin, the glacial-interglacial transition (15000-6000 cal. BP; Alley et al., 2005; Wilson et al., 2008) is associated with the transition from hunter-gatherer societies of the Upper Paleolithic and Mesolithic farmer societies of the Neolithics (Kozlowski, 2005; Bar Yosef, 2006). It is also the time of a major bio-climatic transition between cold steppe environments of the last glacial maximum and sub-Mediterranean environments corresponding to a climate similar to the current interglacial (Bar-Matthews et al., 1997; Allen et al., 2002; Lawson et al., 2004; Bordon et al., 2008). The possible links between these major cultural changes and bio-climate changes have already been extensively debated. However, they resume their relevance today as the scientific advances in the field reveal palaeoclimatic and archaeological issues far more complex (Magny, 1993; van Geel et al., 1996; Kukla et al., 1997) across the Mediterranean world (Cullen et al., 200...
