Abstract

In this paper we test the association between aggression, AR gene polymorphism and reproductive success as expressed in the number of children born in males from two African societies (Hadza, nomadic foragers) and (Datoga, pastoralists). The data on 439 adult African males (210 Hadza and 229 Datoga males, respectively) were collected between 2007 and 2013 in Northern Tanzania, Lake Eyasi region. Men with lower number of CAG repeats of the AR gene rated themselves as more aggressive. Age and the number of CAG repeats were significant predictors of the number of children born. Men with lower number of CAG repeats started reproduction in earlier age and were generally more successful in reproduction in both ethnics. Men with higher numbers of CAG repeats start to reproduce later in Datoga. Supported by RFHR, # 12-01-00032, RFBR # 12-04-31869 and # 13-04-00858.
