Michael Hardimon has some of the best defenses of the reality of race that I am aware of. His 4 concepts are: the racialist concept (he says racialist races do not exist, which I will cover in the future), the minimalist race concept, the socialrace concept (which also will be covered more in depth in the future) and the populationist race concept. Racialist races do not exist, according to Hardimon. However, that does not mean that race does not exist nor does it mean that race isn’t real. On the contrary, race exists and is a biological reality. Simple arguments for the existence of race do indeed exist and see where mixed-race individuals, ‘Latinos’, and Brazilians fall. (Author of the book A Theory of Race Joshua Glasgow also reviewed Hardimon’s book (Glasgow, 2018), and I also left my thoughts on his review.)

Now, minimalist races exist and are biologically real. The concept, though, is vague. It doesn’t state which populations are races, but the populationist race concept, however, does. Hardimon (2017: 99) defines populationist races:

“A race is a subdivision of Homo sapiens—a group of populations that exhibits a distinctive pattern of genetically transmitted phenotypic characters that corresponds to the group’s geographic ancestry and belongs to a biological line of descent initiated by a geographically separated and reproductively isolated founding population.”

Are there groups that exhibit patterns of a distinctive pattern of visible physical features which are genetically transmitted and correspond to the group’s geographic ancestry? Are there groups that belong to a biological line of descent which was initiated by geographically and reproductively isolated founding populations? The answer is, obviously, yes. Which groups satisfy the definition of populationist races? I will discuss this below.

An important question to answer is: are races subspecies? The two terms are similar. Merriam Webster defines subspecies as: “a category in biological classification that ranks immediately below a species and designates a population of a particular geographic region genetically distinguishable from other such populations of the same species and capable of interbreeding successfully with them where its range overlaps theirs.” While “race” is similarly defined. So, are races subspecies?

The fixation index (Fst) is a measure of population differentiation due to genetic structure which is estimated from SNPs or microsattelites. Generally, the accepted criterion for subspeciation is between .25 and .30. Human groups have an Fst between .05 and .15, so human groups fall way short of subspeciation. Fst estimates for humans fall between .05 and .15, which is far and away what the consensus is on the delineation of subspecies within a group of like kinds. Further, Fst does not support the existence of distinct clusters in humans (Maglo, Mersha, and Martin, 2016; it should be noted that they believe that for human races to exist, human races must be subspecies—similar views are held by philosopher of science Adam Hochman—but their contentions were addressed by Spencer, 2015). Human populations are not subspecies, and the fact that they are not subspecies does not rail against the existence of populationist races.

Hochman (2013) makes the case that in order to claim that clusters represent subspecies, four conditions have to be met: “(i) the range of allele frequency differences between genetic Fstclusters corresponding to race must be relatively uniform, (ii) there must be a determinate number of such clusters, (iii) the allelic frequencies within such clusters must be relatively homogeneous, and (iv) there must be a large jump in genetic differences between such clusters” (Hardimon, 2017: 108).

Thus, the human species does not contain subspecies in the technical sense of the word, as humans Fst estimates range between .05 to .15. This further attests to the fact that the clusters—identified by Rosenberg et al (2002)—are not subspecies. “There is no need for US racial groups to be subspecies or clades, have high genetic variation among them, or be fundamental categories in human population genetics just in order to be biologically real races. Rather, in order for US racial groups to be biologically real races, they just need to be races and biologically real (Spencer, 2015: 6).

The populationist race concept, however, does not require that a division in a species be represented by a particular Fst estimated. It further doesn’t say that Hochman’s (2013) conditions must be met in order for the clusters to be races. Therefore the populationist race concept is not a subspecies concept; there are no subspecies in our genus. Though, if we were forced to accept Hochman’s (2013) conditions (which we do not have to), human races do not exist.

Next is the concept of phylogeny. If phylogenetic is taken to in the normal biological terminology, then the question is whether or not racial lines of descent capture evolutionary significant relationships. And if “evolutionary significant relationships” are taken in the normal biological context then the answer to the question is “no.” This is because the term “evolutionary significance”, taken in the general biological terminology, is understood in a way that for a relationship between populations to be “evolutionarily significant”, then the differences between these populations must be blocked by extensive gene flow.

However, regarding the populations that we take to be populationist races, if the features of these races have adaptive significance, such as skin color for differing climates, then the populationist race concept is of interest to evolutionary biologists since biological raciation makes it possible for divisions of Homo sapiens to survive in different climates. Thus, when discussing how and why divisions of our species adapted to different climates—physically speaking—then this concept is of use to evolutionary biologists since it can explain the adaptive physical features of divisions of Homo sapiens. We then have two choices. We can then further take the idea that to be “phylogenetic”, populations must block extensive gene flow, though we can grant that populationist races may well be of interest to evolutionary biologists (due to their adaptive features that arose due to climatic adaption), despite the fact that populationist races are nonphylogenetic (Hardimon, 2017: 111).

The populationist race concept is a candidate scientific concept. This is because the concept uses biological terminology such as “reproductive isolation”, “transmitted phenotypic characteristics”, “founding population”, and “geographic ancestry.” Hardimon then discusses how and why the concept can form a scientific concept:

“… concept C has the “form” of a scientific concept in biology if

(i) it is formulated in a “biological vocabulary”,
(ii) it is framed in terms of an accepted biological outlook,
(iii) it is suitable for deployment in an accepted branch of biological inquiry, and
(iv) it presents the scientific ground of the phenomenon it represents” (Hardimon, 2017: 112).

This concept satisfies all four conditions. It satisfies (i) since it uses biological vocabulary (e.g., phenotype, reproductive isolation). It satisfies (ii) since it’s framed in what Mayr terms “population thinking” (which is the rejection of essentialism—“the view that some properties of objects are essential to them.”. It satisfies (iii) since it is suitable for deployment in ecology, ethology and evolutionary biology. Areas of study, for example, can focus on how and why differing populationist races have differing patterns of visible physical features (i.e., how and why phenotypes changed as migration occurred out of Africa into Eurasia, the Pacific Islands and the Americas). And it satisfies (iv) in that representing populationist races as having arisen from reproducively isolated founding populations.

Now which groups are candidates for populationist races? There are two conditions: (1) they exhibit distinctive patterns of phenotypic characters which correspond to that population’s geographic ancestry and (2) belong to biological lines of descent which then trace back to geographically separated and reproductively isolated founding populations.

There are populations which exhibit distinctive patterns of visible physical features which correspond to geographic ancestry, and they are Sub-Saharan Africans, Caucasians, East Asians, Native Americans and Pacific Islanders. The distinctive patterns of visible physical features are genetically transmitted, and they correspond to geographic ancestry. These populations belong to biological lines of descent which can then be traced back to geographically separated and reproductively isolated founding populations. Thus, conditions (1) and (2) are satisfied, therefore populationist races exist.

Further support for (iii) (that the populationist race concept can be deployed in the biological sciences) can be found in my article You Don’t Need Genes to Delineate Race. I discussed differences in gross morphology between the races; I discussed differences in physiognomy between the races; and, of course, the differences in geographic ancestry that caused the differences in morphology and physiognomy (see here for discussions on skin color). Differences in climate that Homo sapiens encountered after trekking out of Africa then caused the distinctive differences in visible physical features which correspond with geographic ancestry which then make up populationist races. Thus, the study of populationist races will elucidate the caused of phenotypic differences between populationist races since they exist and are a biological reality.

There is a relationship between populationist and minimalist races, though they’re defined by different concepts. However if minimalist races are populationist races, then the kind minimalist race=populationist race. “The claim that minimalist race=populationist race is analogous to the claim that water=H2O. The latter claim, since true, provides scientific insight into the nature of minimalist race” (Hardimon, 2017: 120).

Furthermore, we can assume that the populations identified by Lewontin (1972) as races can be interpreted as lending support to the biological reality of populationist races exist. We can also assume that African, Caucasians, East Asians, Oceanians, and Native Americans constitute populationist races, then Rosenberg et al (2002) show support for the biological reality of populationist races, even though the fraction of diversity separating the clusters is between 3-5 percent, this still shows that populationist races capture a portion of biological human variation, no matter how small it is.

“If it is assumed that Africans, Eurasians, East Asians, Oceanians, and Americans constitute continental-level populationist races, Rosenberg and colleagues’ 2002 study can be interpreted as providing support for the biological reality of populationist race inasmuch as it shows that a very small fraction (3-5 percent) of human genetic variation is due to difference among continental-level populationist races. Modulo our assumption, the study results indicate that populationist race is a minor principle of human genetic structure and that populationist race is a minor principle of human variation.” (Hardimon, 2017: 124)

The same points made that minimalist races are human population partitions, that races can be distinguished at the level of the gene, and that the continental-level minimalist races differ in a small number of coding genes, also carry over to the populationist race concept since minimalist race=populationist race, so the biological reality of minimalist race carry over to populationist race. So if the five populations are populationist races, then populationist race correspond to a partition of genetic variation found between the races in the human species, which is then evidence for the existence of populationist races.

The five populations that make up populationist races are Native Americans, Caucasians, East Asians, Pacific Islanders, and Sub-Saharan Africans. These populations are biologically real, and they exist. They generically transmit phenotypic characteristics across the generations; these phenotypic characteristics differ due to geographic ancestry. These populations are identified in numerous K = 5 runs. So if we assume that the five populations are populationist races then K = 5 shows the real, but small, human genetic variation found within continental-level populationist races which is how the visible patterns of visible physical features which correspond to geographic ancestry are genetically transmitted.

The populationist race concept is a candidate scientific concept. This is a way to study the small genetic variation between the continental-level clusters. Human phenotypic (and physiologic) differences arose due to adaption to different climates. Thus, since populationist race is a biological reality then studying populationist races will better elucidate how and why differences in phenotype arose.

Both the populationist and minimalist race concepts are vague, I admit. However, they’re not so vague that one could argue that villages, countrys, social classes etc are populationist races. It should be noted, though, that it is implicitly stated in the definition for populationist race, that a morphological component exists. Therefore, groups like the Amish, social classes etc. Thus, the populationist race concept gaurentees that races will be races in the ordinary sense of the word (see Hardimon, 2003). So we can take two groups—G1 and G2—and if G1 does not have any pattern of visible physical features which distinguish it from another group, G2, then G1 is not a race. These visible physical differences that distinguish races from one another are biological in nature—hair color/type, skin color, eye type, morphology etc. This gaurentees that different villages, countries, economic classes and ethnies within a race are not counted as “races”, so defined.

The thing about the populationist race concept is that it directly relates to the minimalist race concept. Once we acknowledge that races exist and are real (since minimalist races exist and are real), then we start thinking “Which populations sastisfy the conditions of populationist races?” The populationist race concept—in tandem with the minimalist race concept—shows us that the patterns in visible physical features are genetically transmitted characters which which correspond to the population’s geoprahic ancestry who belong to biological lines of descent which were initiated by geographically separated and genetically isolated founding populations. The populationist race concept supports the claim that the minimalist race concept is a biological concept and secures the existence of minimalist races since minimalist race=populationist race.

P1) The five populations demarcated by Rosenberg et al (2002) are populationist races; K = 5 demarcates populationist races.
P2) Populationist race=minimalist race.
P3) If populationist race=minimalist race, then everything from showing that minimalist races are a biological reality carrys over to populationist races.
P4) Populationist races capture differences in genetic variation between continents and this genetic variation is responsible for the distinctive patterns of visible physical features which correspond to geographic ancestry who belong to biological lines of descent which were initiated by geographically isolated founding populations.
C) Therefore, since populationist races=minmalist races, and visible physical features which correspond to geographic ancestry are genetically transmitted by populations who belong to biological lines of descent, initiated by reproductively isolated founding populations, then populationist races exist and are biologically real.

  1. off topic but…

    sweden just got mannschaft-ed!

    another and more obvious reason why blacks do not dominate soccer is…

    it’s technical. witness the above vid!

    it’s not just a matter of physique.

  2. it’s interesting…

    germany has selected the best INDIVIDUAL at each position…i assume.

    the result is that germany, which has always scored on headers, is SHORT.

    and thus has 0% chance of winning the cup.

    but italy’s team has always been yuge…even though italians are on average shorter than germans.

    the italians have been like american football players…but fit.

    the world cup without italy and without the netherlands is fake news.
