How many human races are there in the world?
The answer is a complex question, and there doesn’t seem to be agreement among anthropologists about the “right” answer.
For instance, some have argued that what counts is simply whether a person can produce fertile offspring with another–even if this occurs on an occasional basis. In other words, they argue that because two people are able to produce fertile offspring together even though they appear from our society’s view of race not to be the same “race”, then they should both not counted as just one but could be counted as two different races. Others have argued that the determination of what constitutes race is based on where groups live and their migration patterns over time through population dispersal.
