Fieldwork is a central method of research throughout anthropology, a much-valued, much-vaunted mode of generating information. But its nature and process have been seriously understudied in biological anthropology and primatology. This book is the first ever comparative investigation, across primatology, biological anthropology, and social anthropology, to look critically at this key research practice. It is also an innovative way to further the comparative project within a broadly conceived anthropology, because it does not focus on common theory but on a common method. The questions asked by contributors are: what in the pursuit of fieldwork is common to all three disciplines, what is unique to each, how much is contingent, how much necessary? Can we generate well-grounded cross-disciplinary generalizations about this mutual research method, and are there are any telling differences?
