First off, OH MY GOD

Let's take a moment to appreciate how gorgeous this man is. Holy hell I want to find him and have his babies. Damn he's beautiful. Anyways, I have a question. This man is African and have you noticed that people from Africa have their own look? I'm not really educated on this so bare with me as I make myself look very stupid lol But why is it that they have a certain facial structure and African Americans don't have this facial structure? Could it be from mixing of races over time?  I notice that people from different parts of the world look different too not just Africa but not in all places WHY is that? I'm simply just curious. Educate me please.😂
