Phylogenic diversity map

Today, in my evolution and diversity class, my professor had a power point slide of this map, which represents the phylogenic diversity of mitochondrial DNA in humans. When this map came onto the screen I was astonished immediately.

Even though Africa is the origin of the tree and it has the most diversity, the pie chart on the image suggests that Africa has the least amount of diversity. The populations measured with more acuity represent the compelling interest of the person who is creating this map. Also, the color scheme chosen for the earlier categories, which are combined into three large groups, are represented by a gray scale while the rest of the phylogenic groups have colors of the rainbow. Even though this map is based on scientific measurements, the map seems to be depict certain races over others in a type of phylogenic hierarchy.
