Race and Identity -- What Race Inhabits Your Skin?



If someone asked you to describe your identity to them, where would you begin? Your nationality? Your language? Your skin color? How about your race?

Just what is “race” and how did the term begin?

Nina Jablonski, an anthropologist and palaeobiologist at The Pennsylvania State University, who is known for her research into the evolution of human skin color, says this about race …

'Race' and 'ethnicity' have been and continue to be used as ways to describe human diversity. Race is understood by most people as a mixture of physical, behavioral and cultural attributes. Ethnicity recognizes differences between people mostly on the basis of language and shared culture."

So, race is usually perceived as something inherent in our biology. It is commonly understood to be inherited across generations. Emma Bryce, Live Science contributor, explains the history of the term …

The idea of 'race' originated from anthropologists and philosophers in the 18th century, who used geographical location and phenotypic traits like skin color to place people into different racial groupings. That not only formed the notion that there are separate racial "types" but also fueled the idea that these differences had a biological basis.”

By the 18th century, race was widely used for sorting and ranking the peoples in the English colonies – Europeans who saw themselves as free people, American Indians who had been conquered, and Africans who were being brought in as slave labor

Then, in the first half of the 19th century, one of America’s most prominent scientists was a doctor named Samuel Morton, a man who accepted skulls scavenged from battlefields and snatched from catacombs, proported that people could be divided into five races and that these represented separate acts of creation. The races had distinct characters, which corresponded to their place in a divinely determined hierarchy.

Morton’s “craniometry” showed, he claimed, that whites, or “Caucasians,” were the most intelligent of the races. East Asians—Morton used the term “Mongolian”—though “ingenious” and “susceptible of cultivation,” were one step down. Next came Southeast Asians, followed by Native Americans. Blacks, or “Ethiopians,” were at the bottom. In the decades before the Civil War, Morton’s ideas were quickly taken up by the defenders of slavery. Paul Wolff Mitchell, an anthropologist at the University of Pennsylvania explains …

He had a lot of influence, particularly in the South. When Morton died, in 1851, the Charleston Medical Journal in South Carolina praised him for 'giving to the negro his true position as an inferior race.'”

(Elizabeth Kolbert. “There’s No Scientific Basis for Race—It's a Made-Up Label.”
National Geographic. March 12, 2018.)

Today Morton is known as the father of scientific racism. So many of the horrors of the past few centuries can be traced to this idea that one race is inferior to another. To an uncomfortable degree we still live with Morton’s legacy: Racial distinctions continue to shape our politics, our neighborhoods, and our sense of self.

The effects of this history prevail today because in current definitions of race, there is still an underlying assumption that traits like skin color or hair texture have biological, genetic underpinnings that are completely unique to different racial groups. Yet, the scientific basis for that premise simply isn't there.

Nina Jablonski explains …

"If you take a group of 1,000 people from the recognized 'races' of modern people, you will find a lot of variation within each group. But, the amount of genetic variation within any of these groups is greater than the average difference between any two (racial) groups. What's more, there are no genes that are unique to any particular 'race.'"

Ultimately, there is so much ambiguity between the races, and so much variation within them, that two people of European descent may be more genetically similar to an Asian person than they are to each other.

In other words, no genetic variants occur in all members of one racial group but not in another. This conclusion has been reached in many different studies. Europeans and Asians, for instance, share almost the same set of genetic variations. As Jablonski described earlier, the racial groupings we have invented are actually genetically more similar to each other than they are different – meaning there's NO WAY to definitively separate people into races according to their biology. Jablonski concludes …

"Our research has revealed that the same or similar skin colors – both light and dark – have evolved multiple times under similar solar conditions in our history. A classification of people based on skin color would yield an interesting grouping of people based on the exposure of the ancestors to similar levels of solar radiation. In other words, it would be nonsense."

(Emma Gryce. “What's the difference between race and ethnicity?”

Let's repeat this important sentence: there is no firm genetic basis behind racial classification. Instead, race is a highly flexible way in which societies lump people into groups based on appearance that is assumed to be indicative of deeper biological or cultural connections. As a cultural category, the definitions and descriptions of races vary.

Also important to understand that geographic ancestry is not the same thing as race. African ancestry, for instance, does not tidily map onto being “black” (or vice versa). In fact, a 2016 study found wide variation in osteoporosis risk among women living in different regions within Africa. Their genetic risks have nothing to do with their socially defined race.

(Alan Goodman. “Race Is Real, But It’s Not Genetic. Sapiens.org. March 13, 2020.)

Professor Alan Goodman, biological anthropologist, says …

In 1972, Harvard evolutionary biologist Richard Lewontin had the idea to test how much human genetic variation could be attributed to 'racial' groupings. He famously assembled genetic data from around the globe and calculated how much variation was statistically apportioned within versus among races. Lewontin found that only about 6 percent of genetic variation in humans could be statistically attributed to race categorizations. Lewontin showed that the social category of race explains very little of the genetic diversity among us.

Furthermore, recent studies reveal that the variation between any two individuals is very small, on the order of one single nucleotide polymorphism (SNP), or single letter change in our DNA, per 1,000. That means that racial categorization could, at most, relate to 6 percent of the variation found in 1 in 1,000 SNPs. Put simply, race fails to explain much.”

(Alan Goodman. “Race Is Real, But It’s Not Genetic. Sapiens.org. March 13, 2020.)

Exactly how different are members of what the the world commonly classifies as “races”? A 2002 Stanford study found that only 7.4% of over 4000 alleles were specific to one geographical region. Furthermore, even when region-specific alleles did appear, they only occurred in about 1% of the people from that region – hardly enough to be any kind of trademark. Thus, there is no evidence that the groups we commonly call “races” have distinct, unifying genetic identities. In fact, there is ample variation within races.

So, when you hear “Black” or “White” or “African-American” or “Caucasian,” think of the “human race” – one beautiful, general classification. The truth is that we, discriminating people, “made up” categories of race. And now, we, the ancestors of those same old scientists and true believers, still perpetuate the concept of racial differences. And, that is extremely disturbing – in fact, unbearable – because in 2020 what we know as “race” can still determine people’s perceptions, their opportunities, and their experiences.

We often have this idea that if I know your skin color, I know X, Y, and Z about you. So I think it can be very powerful to explain to people that all these changes we see, it’s just because I have an A in my genome and she has a G.”
