Biological Construction
By . . ."biological race," I mean the view of race espoused by Judge Tucker, and still popular today, that there exist natural, physical divisions among humans that are hereditary, reflected in morphology, and roughly but correctly captured by terms like Black, White, and Asian (or Negroid, Caucasoid, and Mongoloid). Under this view, one's ancestors and epidermis ineluctably determine membership in a genetically defined racial group. The connection between human physiognomy and racial status is concrete; in Judge Tucker's words, every individual's race has been "stampt" by nature. . . .[D]espite the prevalent belief in biological races, overwhelming evidence proves that race is not biological. Biological races like Negroid and Caucasoid simply do not exist. [A]. . . newly popular [argument] among several scholars, [is] that races are wholly illusory, whether as a biological or social concept. Under this thinking, if there is no natural link between faces and races, then no connection exists.
There are no genetic characteristics possessed by all Blacks but not by non- Blacks; similarly, there is no gene or cluster of genes common to all Whites but not to non-Whites. One's race is not determined by a single gene or gene cluster, as is, for example, sickle cell anemia. Nor are races marked by important differences in gene frequencies, the rates of appearance of certain gene types. The data compiled by various scientists demonstrates, contrary to popular opinion, that intra-group differences exceed inter-group differences. That is, greater genetic variation exists within the populations typically labeled Black and White than between these populations. This finding refutes the supposition that racial divisions reflect fundamental genetic differences.
