This ten-page undergraduate paper will try to prove whether there is evidence of sexual dimorphism in Homo Habilis or not. The pattern of sexual dimorphism that will be followed is based on Steve Donnelly's paper and the specific fossil specimens that will be used are KNM-ER 1813 and KNM-ER 1470. The similarities and differences between the two will also be compared. 10 pgs. Bibliography lists 7 sources.
