The Ache are a small indigenous population living in eastern Paraguay who, in the space of a single generation, have been transformed from autonomous hunter-gatherers to mission/reservation Indians. Hill and Hurtado began collecting demographic data on them in the late 1970s, and this study is the fruit of years of accumulated research. Their approach is grounded in evolutionary ecology. The chief methodological tool is life history theory, which concerns such matters as the timing of maturation, patterns of fertility and mortality in populations, and the assessment of optimal strategies and trade-offs… Upper-division undergraduates and above.” —O. Pi-Sunyer, Choice "...a magnificent achievement, and a landmark in at least three distinct fields: anthropological demography, human evolutionary ecology, and hunter-gatherer studies...." — Evolutionary Anthropology
