From a comparative perspective, human life histories are unique and raising offspring is unusually costly: humans have relatively short birth intervals compared to other apes, childhood is long, mothers care simultaneously for many dependent children (other apes raise one offspring at a time), infant mortality is high in natural fertility/mortality populations, and human females have a long post-reproductive lifespan. These features conspire to make child raising very burdensome. Mothers frequently defray these costs with paternal help (not usual in other ape species), although this contribution is not always enough. Grandmothers, elder siblings, paid allocarers, or society as a whole, help to defray the costs of childcare, both in our evolutionary past and now. Studying offspring care in a various human societies, and other mammalian species, a wide range of specialists such as anthropologists, psychologists, animal behaviorists, evolutionary ecologists, economists and sociologists, have contributed to this volume, offering new insights into and a better understanding of one of the key areas of human society.
"[This book] brings together high-quality papers from many different fields: endocrinology, evolutionary biology, demography, economics, psychology, sociology, anthropology? It can be seen as a practical tool for researchers in the field, and it provides a large amount of data across a wide range of populations and helps to find a common ground between theories emerging from different fields. It is the kind of book that will never end up in the last dusty row of your shelves because you will continually refer to it, picking up here and there empirical and theoretical data for the next decades." · BioOne.
