            "abstractNote": "I argue that the magnitude and nature of sex differences in aggression,   their development, causation, and variability, can be better explained   by sexual selection than by the alternative biosocial version of social   role theory. Thus, sex differences in physical aggression increase with   the degree of risk, occur early in life, peak in young adulthood, and   are likely to be mediated by greater male impulsiveness, and greater   female fear of physical danger. Male variability in physical aggression   is consistent with all alternative life history perspective, and   context-dependent variability with responses to reproductive   competition, although some variability follows the internal and external   influences of social roles. Other sex differences, in variance in   reproductive output, threat displays, size and strength, maturation   rates, and mortality and conception rates, all indicate that male   aggression is part of a sexually selected adaptive complex. Physical   aggression between partners can be explained rising different   evolutionary principles, arising from the conflicts of interest between   males and females entering a reproductive alliance, combined with   variability following differences in societal gender roles. In this   case, social roles are particularly important since they enable both the   relatively equality in physical aggression between partners from Western   nations, and the considerable cross-national variability, to be   explained.",

The present critique summarises evidence from systematic   reviews of interventions, from empirical tests of the Activitystat   hypothesis, from studies on the heritability of physical activity in   childhood and the physical activity of children of and adolescents   across a wide range of physical and cultural environments. This body of   evidence is inconsistent with the Activitystat hypothesis in its current   form, and suggests that the emphasis on physical activity in obesity   prevention interventions in children should be increased, not reduced.
