Race is synonym for subspecies in biology. Humans are polytypic, not monotypic. Racial diversity is biologically real, not social construct. Social constructivism appeals to motive, ignores science. 85% genetic variation within races does not negate between-race differences. Lewontin's single-locus misclassification fallacy fails with multiple loci. Multiple traits correlate to enable near-perfect racial classification. Races show distinct correlative structures of traits. All four major race definitions unite under correlation structure framework. Historical gene flow barriers evolved racial differences. Classical racial groups are taxonomically valid. Phenotypic similarity and range restriction define races. Mendelian populations correspond to races. Eco-geographical distinctions align with racial genetics. Anthropologists deny races more than biologists.
