Beyond the Ferguson, Mo., media reports on the “racial divide,” the facts require some correction: Despite notions to the contrary, there is only one human race. Our single race is independent of geographic origin, ethnicity, culture, color of skin or shape of eyes — we all share a single phenotype, the same or similar observable anatomical features and behavior.
Science highlights these similarities in our embryonic development, physiology (our organ-based systems), biochemistry (our metabolites and reactions), and more recently, genomics (our genetic makeup). As a molecular biologist, this last one is indeed the most important to me — data show that the DNA of any two human beings is 99.9 percent identical, and we all share the same set of genes, scientifically validating the existence of a single biological human race and one origin for all human beings. In short, we are all brothers and sisters.
