Mated humans that perform different activities from each other in their ecological niche will be associated with an increase in sexual dimorphism (557).
For the purposes of this test, attained adult stature of males and females is used to measure sexual dimorphism in humans. For the measures of differential activities, degree of sex differentiation in the subsistence economy (rho = .47) and degree of paternal involvement (rho = -.74) in the largely female activity of child caretaking are used. Both correlations support the hypothesis (557).
