Building Babies features multi- and trans-disciplinary research approaches to primate developmental trajectories and is particularly useful for researchers and instructors in anthropology, animal behavior, psychology, and evolutionary biology. This book also serves as a supplement to upper-level undergraduate courses or graduate seminars on primate life history and development. In these contexts, the book provides exposure to a wide range of methodological and theoretical perspectives on developmental trajectories and models how researchers might productively integrate such approaches into their own work.
