When attempting to describe biological "race" we need to include the concepts of phenotype, cline and our vast family tree roots.

phenotype: the set of characteristics of a living thing, resulting from its combination of genes and the effect of its environment

cline: a series of similar items in which each is almost the same as the ones next to it, but the last is very different from the first

family tree roots: We each have over a million ancestors counting back only 20 generations. As the roots expand they cover a larger geographic area.

Many anthropologists don't believe in the controversial concept of biological "race", rather they understand the facts of biological phenotypes and clines.
