THE ORIGINS OF SEXUAL DIMORPHISM IN BODY SIZE IN UNGULATES - P�rez-Barber�a - 2007 - Evolution - Wiley Online Library: "Jarman (1974) proposed a series of relationships between habitat use, food dispersion, and social behavior and hypothesized a series of evolutionary steps leading to sexual dimorphism in body size through sexual selection in African antelope species. The hypothesis states that sexual size dimorphism evolved in a three-step process. Initially, ancestral monomorphic and monogamous ungulate species occupying closed habitats radiated into open grassland habitats."
