Continuous variation is best described as?

Continuous variation is best understood as phenotypic variation on a spectrum. This concept refers to the range of differences in phenotypic traits that individuals within a population can exhibit, which are not just limited to distinct categories but instead fall along a continuum. For example, traits such as height, skin color, or weight can show gradual differences rather than being grouped into separate classes.

This understanding of continuous variation is important in anthropology and biology because it illustrates how diverse and nuanced traits can be within both human populations and other species. In contrast, categorization of traits involves defining them in distinct groups, which doesn’t adequately account for the subtle gradations that continuous variation highlights. Similarly, binary distinctions simplify traits into two opposing categories, overlooking any intermediate forms. Lastly, the concept of an evolutionary gap does not align with continuous variation, as it implies a more drastic division or lack of connection between species, rather than showing the gradual changes that occur within traits.
