Abstract
The species Homo sapiens results from interbreeding between modern humans, Neanderthals and Denisovans that occurred tens of thousands of years before the beginning of human migration from Africa. Human beings share 99.9% of the same DNA. People can have diverse ancestry, resulting from the crossing of their ancestors, not only within the same population, but also with other population groups. Molecular studies of DNA have contributed to the elaboration of the evolutionary history of life, particularly human ancestry. In the biological and social sciences, the consensus is clear: “race” is a social construct, not a biological attribute. Moving away from the social connotation of the term "race" implies that science has been changing the way it refers to human populations and accepting the existence of a single species, Homo sapiens. New terms and other standards must be found to describe the biological diversity of people, included in public policies for negative non-negative discrimination at international and national levels.
