“…Speculation about European, Caucasus or Central Asia origins for broomcorn millet arose from multiple sites in central and eastern Europe, and the Caucasus, apparently of comparable antiquity (pre-5000 BC) to those in China (reviewed in Hunt et al, 2008 ), and the lack of archaeobotanical research in Central Asia. In recent years, systematic flotation and direct dating of Panicum grains at sites from Neolithic cultures across northern China have vastly increased the evidence base for pre-5000 BC broomcorn millet with domesticated-type morphology here ( Crawford et al, 2016 ; Gansu Provincial Institute of Cultural Relics and Archaeology (GPICRA), 2006 ; Lu et al, 2009 ; Tao et al, 2011 ; Wu et al, 2014 ; Yang et al, 2012 ; Zhang et al, 2012 ; Zhao, 2011 , 2014 ; summarised in Ren et al, 2016 ). In contrast, direct dating of macrofossils from central and eastern Europe showed that their previous early Neolithic attributions were incorrect, and they date rather to ~1500 BC (the European Bronze Age) at the earliest ( Motuzaite-Matuzeviciute et al, 2013 ).…”
