Africa,like no other continent,has two dinstinct human races(Africoid or Negroid now becoming a more obsolate name due to it's racial attachments.)to the south of the sahara and the caucasian population who inhabit the Maghreb north of the sahara.these two developed the first world civilisations.Now in personal views,has these cultures really affected or influenced other people all over the world? If yes,which ones have had more more influence,or become more popular.Inter- racially and intra-racially.
