"So I think we've established that the animal race concept is equivalent to the human race concept. I therefore propose to write "is a social construct" in the first sentence. Captain JT Verity MBA" If you write that in the first sentence it will be removed by every biologist who comes across the page.  The name of this page is "Race (biology)", which is not a social construct. As has been noted above, animal breeds are the result of human selection, whereas a race of animals within a species (or within a subspecies or variety) arises through natural means (notably by vicariance). Eventually, a human may notice something that distinguishes the races of animals and may call attention to it or give it a name. That is a concept, however, not a social construct. As it says at Social constructionism, "Social constructs are the by-products of countless human choices". If a biologist talks about the long-tailed race of Macaques, that may be of no interest to anyone but that scientist and those who read their papers. Biological races have fuzzy boundaries, not all individuals can be delineated according to biological race. Human social constructs, however, assign a single race to each person. If you apply for a driver's licence in the U.S. and don't fill in the race field, I know from experience that a desk clerk will look at you, take a guess, and check exactly one box on the form, and the boxes don't include  "none" or "mixed-race", just some other offensive terms that supposedly divide people by a combination of skin colour, hair curliness, and eye shape.
