content: Series 2 consists of materials relating to Walker's primate research from 1970-1988, 1997, and undated.  Materials include data and interpretation, field notes, correspondence, illustrations, photographs, x-rays, and dental impressions.

Walker's early great ape research is primarily material in support of his doctoral thesis, Great ape feeding behavior and incisor morphology (1973, University of Chicago). This includes work with primates in captivity at Yerkes Regional Primate Research Center at Emory University and extensive data about primate dentition. The Guatemala field work deals with Walker's research on the feeding behavior of free-ranging primates circa 1975. There is extensive material on the Alouatta pigra (Guatemalan black howler monkey) and Ateles geoffroyi (Geoffroy's spider monkey) as well as material supporting papers written based on the field work. Other primate research and materials includes material primarily dated between 1979-1988 and undated and includes materials on cusp angle, lip mobility, and underbite. This section also includes miscellaneous research and reference materials and one sound cassette labeled "Gibbons."  Some of the undated material may relate to the two previous subseries, but it is unclear.
