Comment:

Ethnic Groups and races change over time. For example; a French person over 300 years may start out in France as a White person but end up in West Virginia as a Black person. They can start out in France (ethnic group) and White (race) but 300 years later end up as an American(ethnic group) and Black (race). 

So ethnic group as well as race is not a scientific fact. But characteristics of diet and living conditions can identify people in many parts of the world.
