In this revised and updated edition of the landmark publication, Robert W. Shumaker and Kristina R. Walkup join Beck to reveal the current state of knowledge regarding animal tool behavior. Through a comprehensive synthesis of the studies produced through 2010, the authors provide an updated and exact definition of tool use, identify new modes of use that have emerged in the literature, examine all forms of tool manufacture, and address common myths about non-human tool use. Specific examples involving invertebrates, birds, fish, and mammals describe the differing levels of sophistication of tool use exhibited by animals.
Robert W. Shumaker is the vice president of life sciences at the Indianapolis Zoo, the author of Orangutans, and coauthor, with Benjamin B. Beck, of Primates in Question. Kristina R. Walkup is an adjunct assistant professor at Drake University. Benjamin B. Beck is the director of conservation at Great Ape Trust.
