In Search of the Broad Spectrum Revolution in Paleolithic Southwest Europe

L’exploitation de l’Ours au Paléolithique : un point sur la question

“…Notons néanmoins que ce caractère apparaît fortement variable d'un site à l'autre tant au niveau des espèces concernées que de leur importance relative. Dans cette région, l'exploitation du monde animal à l'Azilien comme au Laborien est moins bien connue ; mais les données indiquent encore que les activités cynégétiques sont orientées vers les ongulés -cheval, cerf ou aurochs -et les petits gibiers -lapin, castor notamment - (Cochard, 2004 ;Jones, 2004Jones, , 2016Fat Cheung et al, 2014 ;Langlais et al, 2014aLanglais et al, , 2015aChevallier, 2015).…”

“…Ces modèles mettent en cause les conditions environnementales, l'augmentation de la pression démographique, une baisse de la mobilité des groupes humains, les innovations techniques ou encore des changements dans l'organisation sociale (e.g. Stiner et al, 1999 ;Stiner, 2001 ;Stiner et Munro, 2002 ;Hockett et Haws, 2003Cochard, 2004 ;Cochard et Brugal, 2004 ;Costamagno et Laroulandie, 2004 ;Müller, 2004 ;Costamagno et al, 2008 ;Costamagno et al, 2009 ;Rillardon et Brugal, 2014 ;Jones 2016…”

Using niche construction theory to generate testable foraging hypotheses at Liang Bua

“…31,32 In doing so, many models have created a false notion that body-size based abundance indices reflects foraging efficiency-known as the body-size proxy. [33][34][35][36] Testing hypotheses generated from OFT models comes with a unique set of challenges. 20 Because of the cumulative nature of the archaeological record and the indirect means of reconstructing paleoenvironments, parameters such as prey availability, abundance, heterogeneity, and distribution, are not always known 12,37 or cannot be represented accurately using modern analogs.…”

“…This is assuming that a foragers goal was to maximize caloric intake—a goal that is frequently assumed in human OFT models in lieu of other foraging goals, such as balancing diet, taste preference, or social stigmas 31,32 . In doing so, many models have created a false notion that body‐size based abundance indices reflects foraging efficiency—known as the body‐size proxy 33–36 …”

El Paleolítico Superior de la península ibérica

“…9-51, ISSN: 0082-5638 https://doi.org/10.3989/tp.2018.12202 also hint at over-kill of red deer and ibex, even by Magdalenian populations in the southern regions despite being of far lower density than were the populations in the North. A process long underway in Iberia, the "Broad Spectrum Revolution" was an Upper Paleolithic phenomenon that preceded the Pleistocene-Holocene climatic transition and that was probably the result of multiple factors, including environmental changes and imbalances between regional human populations and big game availability, as presaged by research at La Riera Cave (Straus and Clark 1986) and systematically reviewed and analyzed for both Iberia and southern France by Jones (2016). Despite the ecological differences that partially distinguished the subsistence patterns of northern versus eastern and southern Iberia, the basic similarities in lithic and osseous technology, rupestral and portable art and the evidence of transport (down-the-line trade) of exotic/non local objects (flints, seashells) argue for a general, high-level unity of a Late Magdalenian culture based on networks of social relationships among regional bands.…”
