Final answer:
Race is not biologically identifiable and does not determine important qualities of an individual such as intellect, physical ability, and temperament.
Step-by-step explanation:
Biological anthropology demonstrates that race is not biologically identifiable. Each human trait varies along a spectrum, and the various traits are mixed and matched among people in ways that make racial distinctions impossibly inaccurate. For example, skin color varies along a spectrum, from pinkish beige to dark brown, and is influenced by environmental factors. Researchers have provided substantial evidence that refutes a biological-racial basis for intelligence, including the widespread closing of IQ gaps as people gained more access to education. Therefore, important qualities of an individual, such as intellect, physical ability, and temperament, are not determined by his or her racial group.
