Implications of Male and Female Contributions to Sexual Size Dimorphism for Inferring Behavior in the Hominin Fossil Record by Plavcan, J. Michael

“…Sexual dimorphism is commonly used to directly infer or support reconstructions of social behavior in early hominins. This is often done by comparing the…”
