There is universal recognition by biologists that there is a single human race; the concept of multiple races is NOT a biological concept.  The purpose of race concept is to identify groups of people historically subject to racial discrimination, a historical, subjective and legal concept, defined by Census Bureau of Federal government and defined by a questionnaire.  The biological concept that may be linked to IQ is geographic ancestry.  For example, a person of a single race, the Hispanic race, may have a diverse geographic ancestry from Africa, Europe or native people of Latin America. Look at position statement of American Society of Human Genetics: ASHG Denounces Attempts to Link Genetics and Racial Supremacy, Am J Hum Genet. 2018 Nov 1; 103(5): 636.,(reply>), "There is universal recognition by biologists". Where have I heard that one before? "There is universal recognition by virologists". "There is universal recognition by climate scientists". "There is universal recognition by historians". "There is universal recognition by physicists" "There is universal recognition by medical experts". "There is universal recognition by social scientists". "There is universal recognition by psychologists". And so on ad libitum.
