“…Despite this, most models for the introduction of domesticated herd animals and early forms of pastoralism in Mongolia still mostly rely on the more numerous data from burial sites (e.g., Erdenebaatar and Kovalev, 2007;Eregzen, 2016;Kovalev and Erdenebaatar, 2009;Volkov, 1980). Based mostly on this mortuary record, but also museum collections and surface materials from the Gobi Desert (Janz, 2006(Janz, , 2012, and a few settlements in the Russian Altai and the Minusinsk region of Southern Siberia (Kosintsev and Stepanova, 2010;Vadetskaia et al, 2014), two main models have recently been proposed for the introduction and spread of pastoralism in Mongolia, both of them originating with the arrival of Afanasievo groups in the Altai around the 3rd millennium BCE and then spreading east along a southern route (Honeychurch et al, 2021;Janz et al, 2020). However, Janz et al (2020:162) see little to no evidence of herding in the Gobi until the mid-second millennium BCE with what they call a 'second wave of advance in the spread of a pastoralist economy', a period when local hunter-gatherers might have been motivated to adopt herd animals (sheep/goat, cattle) as items of value following enhanced opportunities to engage in expanding trade networks in luxury goods (stone beads in particular).…”
