The association between our ancestors and fire, somewhere around six to four million years ago, had a tremendous impact on human evolution, transforming our earliest human ancestor, a being communicating without speech but with insight, reason, manual dexterity, highly developed social organization, and the capability of experimenting with this new technology. As it first associated with and then began to tame fire, this extraordinary being began to distance itself from its primate relatives, taking a path that would alter its environment, physiology, and self-image. Based on her extensive research with nonhuman primates, anthropologist Frances Burton details the stages of the conquest of fire and the systems it affected. Her study examines the natural occurrence of fire and describes the effects light has on human physiology. She constructs possible variations of our earliest human ancestor and its way of life, utilizing archaeological and anthropological evidence of the earliest human-controlled fires to explore the profound physical and biological impacts fire had on human evolution.
Frances D. Burton is professor of anthropology at the University of Toronto. She has studied primates in Costa Rica, Honduras, Barbados, China, Malaysia, Kenya, Morocco, and Gibraltar, examining the biological bases of behavior. Her many publications include the edited volume Social Process and Mental Abilities in Non-Human Primates: Evidences from Longitudinal Field Studies and a pioneering CD titled ""A Multimedia Guide to the Non-Human Primates.
