I'm guessing the Nigerian spot is there because most Nigeria is halfway between Senegambia, and Angola. With the bulk of Aframs are mixed between these two African compenents. The pull towards the Sahel is because of the Euro ancestry?
Both of my dots are in Nigeria, basically overlapping each other...but towards Niger. My red dot is on the border of Spain and France...which is surprising to me because of where my family is from. Really? Lucky...I want to study abroad. Sounds fun.
I've been to Ethiopia and Tanzania before. I really, really, really, REALLY want to go back to Tanzania. I loved everything about it. I'd love to visit Mali & Senegal, as well as South Africa and parts of North Africa - specifically Morocco and Egypt.
