Remarkable survey of archaeobotanical evidence for early processing of plant foods. Florin and Ramsey emphasize that theirs is a cautious approach to the evidence, but the conclusion is very clear: humans were extracting food from a wide variety of plants in ways that required grinding, leaching, and lots of tool use tens (if not hundreds) of thousands of years before the supposed emergence of sedentary agriculture.
Their discussion of crossing Wallacea is fascinating. They demonstrate the prior existence of a early, culturally transmitted bundle of adaptive skills for identifying, processing, and managing plant foods in new landscapes, including stone tools and fire, but equally, a capacity to discover, utilize, and steward unfamiliar food plants.
They firmly upend the assumption that the archaeology of food is just about eating animals, and open up the question of how old agriculture really is.
