but that is how we evolve, the freaks genes spread, and you dont spread genes faster by delaying breeding, so at a guess more evolved races would have a history of young births and their young women would be bigger and mature faster and their men would be attracted to younger features
nordic women, i have seen many a nordic 12 to 14yr old much bigger than any other races adult women
i thought with all the chemicals girls were bleeding earlier and boys getting tits and becoming sissy etc
