In this book leading experts uncover and discuss archaeological topics and themes surrounding the long-term trajectory of camelid (llama and alpaca) pastoralism in the Andean highlands of South America. The chapters open up these studies to a wider world by exploring the themes of intensification of herding over time, animal-human relationships, and social transformations, as well as navigating four areas of recent research: the origins of domesticated camelids, variation in the development of pastoralist traditions, ritual and animal sacrifice, and social interaction through caravans. Andeanists and pastoral scholars alike will find this comprehensive work an invaluable contribution to their library and studies.
