No Biological Basis for Race. New data from the mapping of the human genome reveal that all humans are incredibly similar-in fact, strong we are 99.9% genetically identical. We are all members of one species, Homo sapiens. Scientists have confirmed, as they long suspected, that there is no genetic or biological basis for race.
Genetic variation between people within the same "racial" group can be greater than the variation between people of two different groups. Many people of African descent are no more similar to other Africans than they are to Caucasians. Genetic distinctions between Asians and Caucasians are less pronounced than those between groups from, for example, parts of East and West Africa.
No matter how scientists today scrutinize a person's genes, they can't determine with certainty whether an individual is from one "racial" group or another. Differences of culture and society distinguish one group from another, but these distinctions are not rooted in biology.
"Mapping the DNA sequence variation in the human genome holds the potential for promoting the fundamental unity of all humankind." —Dr. Harold P. Freeman
