“…This discovery of fire, probably the greatest ever made by man, excepting language, dates from before the dawn of history. Darwin (1890a:48-49) Then, beginning perhaps a mere 20,000 or so years ago, toward the end of the Pleistocene, and in many different parts of the inhabited world -both glacial and non-glacial -came a real inflection point in the rate of food-related intensification, with the addition in rapid succession of many new food types and many new practices and technologies for processing these foods, such as baking, grinding, pounding, steaming, parching, leaching, fermenting, and technologies that permitted boiling and stewing, first using skin, basketry, or gut bags that could be heated indirectly with hot rocks, and then using ceramic containers that could be placed directly over the fire (e.g., Benison 1999;Holt and Formicola 2008;Jones 2009:177-178;Manne et al 2005;Nakazawa et al 2009;Stahl 1989;Thoms 2009;Wandsnider 1997;Wollstonecroft et al 2008). The impact of these comparatively recent innovations in food-processing technologies is indirectly reflected in the dramatic changes that have occurred over the Late Pleistocene and Holocene in tooth size and craniofacial structure (e.g., Brace et al 1987;Lieberman et al 2004).…”
