Kalenjin Nilotic Kenyans and Ethiopian Highlanders have an unfair advantage in marathon running (both physiological (the way they are built) as well as environmental (highland oxygen advantage).The blacks took over the sport industry....the white people are running the world. U will never see a Wakanda world dominance,
West-Central Africans (Niger-Congos) have an unfair advantage in sprint (good fast twitch muscles) and how their legs are built.
