Sexual Dimorphism An encephalization quotient is calculated as a corrected ratio of brain mass to body mass for a particular organism. However, Table II demonstrates the well-known fact that the australopithecines and Homo habilis are sexually dimorphic (Johanson and White, 1979; McHenry, 1986; 1991a; Zihlman, 1985).bstract. The australopithecines and Homo habilis have been publicized for years as examples of evolutionary transitional forms that launched our own human lineage. Dogmatic evolutionists have rationalized these claims on the basis of brain expansion, encephalization quotients, and bipedalism.
