“…These anatomical traits could have influenced behavioural changes within the chronological framework of the Orgnac 3 sequence, such as more careful gestures, reduced force for meat processing activities, or Levallois core technology, all related to an increase in Neanderthal manual dexterity over time (Villemeur, 1994;Churchill, 2001). The gradual introduction of Levallois technology in two phases at Orgnac provides strong evidence for the in situ development of Levallois technology in Europe, one facet of wider social, cognitive, and behavioural change that accompanied the gradual process of "Neanderthalisation" in Europe (Callow and Cornford, 1986;Ashton et al, 1992;Roebroeks et al, 1992;Boëda, 1994;Moncel, 1995;Carbonell et al, 2001;Bar-Yosef and Dibble, 2005;Goval, 2005;Hallos, 2005;Premo and Hublin, 2009;Scott and Ashton, 2011;White et al, 2011). Levallois technology appears to be rooted in MIS 12 ("pre-Levallois" cores described by Tuffreau [1979] and Tuffreau et al [2001] at Cagny la Garenne in Northern France).…”
