Biological Race
Definition
A concept from nineteenth-century physical anthropology that proposed discrete biological categories (races) of Homo sapiens. Modern population genetics and biological anthropology reject discrete biological race as a valid classification for humans; human genetic and phenotypic variation is continuous (clinal) rather than categorical.

Common questions
If biological race is rejected, what do forensic anthropologists estimate instead?+
Practitioners now generally report population affinity or ancestry estimates derived from skeletal metrics compared against reference samples, framed as probabilistic group membership rather than membership in a fixed biological race category. The distinction matters because ancestry estimation acknowledges continuous variation instead of discrete types.
Does rejecting biological race mean ancestry cannot be estimated from skeletal remains?+
No. Statistical methods can still estimate the population or region a set of skeletal traits most resembles, because human populations do differ in average trait frequencies. What is rejected is the older idea that humanity divides into a small number of discrete, non-overlapping biological races.
