“…BP and marks a shift in the regional sequence toward blade-based production, and the Early Upper Paleolithic (EUP), which emerges after 40 ka cal BP. Despite some regional variation between western and eastern Eurasia Zwyns, 2014, 2018;Hoffecker et al, 2019;Kuhn, 2019;Hublin et al, 2020;Fewlass et al, 2020), the IUP is consistent enough in Central and East Asia to be associated with Homo sapiens dispersals along a 'Northern Route' as early as 46-45 ka cal BP (Goebel, 2004(Goebel, , 2015Zwyns, 2012;Fu et al, 2014;Madsen et al, 2014;Rybin, 2014;Hublin, 2015;Hoffecker, 2017;Li et al, 2019;Izuho et al, 2019;Kadowaki et al, 2019;. In addition to specific typological markers (Rybin, 2000(Rybin, , 2014, IUP assemblages often show distinctive technological features that stem from a strong emphasis on the production of blades.…”
