After some deliberation, I determined that the locution “race” is inessential. As such, I now disavow the arguably controversial view that this is necessary when it comes to understanding biological variation, human and otherwise…. At the same time, it has become evident that the concept which I refer to as “lineage population,” which I hitherto called “natural division,” a concept which corresponds with Darwin’s “communities of descent,” as understood in On the origin of species by means of natural selection, or the preservation of favoured races is indispensible. I clarify that concept and discuss it in relation to other systematic ones.
Abstract: The genealogy-based classificatory programs of Kant and Darwin are briefly discussed for context. It is detailed how in biology there is no unambiguous term to reference infraspecific-level descent-based divisions. The term lineage population is introduced and defined for analytic purposes: a lineage population is one of a set of divisions of intrafertile organisms into which members are arranged by propinquity of descent. It is argued that the lineage population concept avoids the ambiguities associated with related biological and anthropological concepts and polysemes such as population, ethnicity, and race. Other terms and concepts, such as form, cline, cluster, geographic population, breeding population, genetic population, breed, species, subspecies, ancestry, geographic ancestry, biogeographic ancestry, ancestral population, ancestry population, natural division, and population lineage, are discussed in relation to this concept. It is concluded that the lineage population concept is a useful analytic tool which picks out, in line with the Kantian/Darwinian perspective, an interesting class of biological variation.
