chosen: People from Africa typically share physical features and features of facial appearance because these traits are heavily influenced by the climate, genetics and natural selection in the region.  Many of the physical characteristics that define ethnicity and identity have been passed down through generations, resulting in similar facial features and skin color across many countries in Africa.  Furthermore, people from Africa often have relatively short distances between their populations due to geographic proximity, leading to further similarity between individuals in a shared area.
