“…These discoveries challenge models based on the notion that isolation and speciation events were the factors responsible for the emergence of modern human cognition. As a result, a number of researchers has argued that the emergence of modern behavior should be investigated at a regional scale, that models aimed at explaining the emergence of modern behavior should account for the variability, including discontinuity, attested in the archaeological record, and that a number of diverse factors (social, demographic, environmental, ecological) needs to be taken into account (e.g., Belfer- Cohen and Hovers 2010;Conard 2008Conard , 2010d'Errico 2003d'Errico , 2009d'Errico et al 2001d'Errico et al , 2003d'Errico et al , 2012bd'Errico et al 2016;d'Errico and Stringer 2011;d'Errico and Banks 2013;Hovers and BelferCohen 2006;Johansson 2014;Nowell 2010;Peresani et al 2013Peresani et al , 2014Romandini et al 2014;Shennan 2001;Villa and Roebroeks 2014;Zilhão 2001Zilhão , 2006Zilhão , 2007Zilhão , 2011.…”
