The skeletons of Gombe chimpanzees provide an opportunity for analysis of bony tissue with reference to known sex and parity in combination with observations on other life history variables and behavior. Measurements of the pelvic bones show a mosaic of sex differences. Well-defined resorption areas on the dorsomedial aspect of the pubis and the preauricular area of the ilium have been associated with sex and parity in humans and other species. However, these are not present in either females or males in this chimpanzee skeletal series.
