This excellent book applies a range of conceptual approaches and an up-to-date data set to the analysis of agricultural origins—an important topic in the prehistory of the American Southwest and, more broadly, in World prehistory. I am not aware of any other recent, single-author publication that provides such a comprehensive review of the subject from across the American Southwest, including such thorough treatment of evidence scattered among what are often obscure (though generally well done) reports from the realm of contract archaeology.
