Race

It is very easy to differentiate a Chinese person from an American personas but this isn't the only way of determining the race of an individual. The idea of race is a modern idea because in ancient time they weren't divided by physical appearances but by religion, status, or language. The first time we can see in practice a definition of race is when Americans created slavery demanding control over similar physical characteristics.  Although this beliefs were taking seriously in the past, in the modern age there is proof that there are no sub species in the human race, we are among the most similar of all species.

In The Power of an Illusion they show how there are no genes or traits that determine a persons race. The genes that determine the sin color are totally different to the ones that determine the hair color or texture in an individual, thats why we can base the definition of ones race in their skin color. 

Racism still exist and society has demanded better opportunities to the whites more the the black race which clearly shows how people don't understand the real definition of race. 

The following link is a way of defining race by Ian F. Haney in a different king of way.
