A total of 18,208 leporid bones from Hogup Cave was analyzed. Approximately 1% of the assemblage bore clear evidence of human modification (cut-marks and breakage patterns) while 8% showed clear evidence of nonhuman modification (digestive damage, presence in scat and pellet matter, and puncture marks). Raptors probably modified the majority of the latter group. The culturally modified bone pattern was consistent through time, suggesting a consistency of behavior throughout the occupation of the site, as predicted by the Desert Culture concept.
