Race is just a social concept.
The Americas is the photographic series of a typology of faces from humans born and raised in the American Continent. It is believe that race is a biologically thing, but scientific research proved that it is a social concept rather than biologic. An specific Race is not seen in the DNA and physical traits are not the response of an specific race. Most human physical variation (85%) occurs between locals group while an smaller percentage (6%) variance occurs between population. It basically explains that there is only one race (human race) and we all come from the same origin and the differences in our physical traits are the result of environmental and inherited factors.
