Book excerpt: "He has spent nearly three decades studying, learning from, crusading for, and thinking about hunter-gatherers, who survive at the margins of the vast, fertile lands occupied by farming peoples and their descendants, now the great majority of the world's population. In material terms, the hunters have been all but vanquished, yet in this profound and passionate book, Brody utterly dispels the notion that theirs is a lesser way of life."--Jacket.
