The Ape and the Sushi Master is a popular science book by Frans de Waal. It is an overview of animal behavior and psychology, with an emphasis on primates. It places a special emphasis on the anthropomorphological traits of primates of several different species. It also includes a short history of anthropomorphology and some of that field's pioneers. The title is meant to reflect an analogy between how primates learn and the cultural process of how sushi-making skills are passed down from master to apprentice. Source: Wikipedia (en)
