Graeber / Wengrow 123: "A cosmopolitan Upper Palaeolithic is followed by a complicated period of several thousand years, beginning around 12,000 BC, in which it first becomes possible to trace the outlines of separate 'cultures' based on more than just stone tools"
"postglacial populations"--the "Mesolithic"
technological innovations include "pottery, 'micro-lithic' tool kits, and stone grinding tools [which signaled[ new ways of preparing and eating wild grains, roots, and other vegetables [...] and also ways of storing, smoking and otherwise preserving meats, plant foods and fish"
"the creation of what we'd now call cuisine"
note that "cuisines are also, almost everywhere, markers of difference"
