The First Race Scientist
13th March 2024
The concept of race, we are often told, is a social construct with no basis in biological reality. Some have argued that it was invented by white Europeans for the express purpose of constructing a racial hierarchy in order to justify slavery. According to cultural critic Kenan Malik, “Racism gave birth to race. The ancestors of today’s African Americans were not enslaved because they were black. They became classified as a distinct, and inferior, race as a means of justifying their enslavement.” This view is even espoused by some scientific institutions.
And yet, by analysing your genome, companies like 23andMe can describe your ancestry, and their reports match people’s own accounts of their racial ancestry to a high degree of accuracy. As humans spread across the globe, they tended to breed within ancestral groups, such that gene flow within groups became greater than gene flow between groups. This led to a pattern of “shared-ancestry clustering” that is still apparent across the world—as a result, we can usually differentiate at a glance between people whose ancestry can be traced back multiple generations in, say, Japan, from those whose ancestors came from Ethiopia or Norway. It is these clusterings that we refer to by the term “race”—a common-language term that predates Enlightenment science.
Despite the fact that there is obviously some biological underpinning to what we call “race,” many people claim that “races” are purely sociological. They argue that races could only be real if they were clearly demarcated, discrete categories and thus countable, or that for races to be real, they must be essentialist categories: i.e., there must be at least one trait shared by all the people of Race A and by no one who is not of Race A.
In support of this, leading geneticist Richard Lewontin pointed out that genes vary just as much within a race as between races. While this is true, it does not negate the reality of races. Our ancestry is manifest in correlated patterns of genetic variation, and these correlated patterns are both real and meaningful and reveal our ancestral groupings. Furthermore, while many dismiss race as only skin deep, AI software can discern a patient’s race just by analysing medical X-rays. The AI cannot just be reflecting human bias when it does so, since it is discerning patterns of which human experts are unaware.
