“I think there’s just one kind of folks. Folks.” — Scout, from To Kill a Mockingbird
Show me a racist, and I’ll show you a fool. We now have evidence — strong scientific evidence — linking racism to stupidity. Scientists have linked racism with low intelligence in what is called a meta-analysis. That is, they have done a study of studies. Doing meta-analyses allows scientists to see wide patterns — kind of like looking at a forest instead of the trees.
Controlling for factors like education and economic status, scientists have found that lower intelligence in childhood predicts greater racism in adulthood (Busseri). In one specific study, scientists examined how well young children could notice, when water was poured from a short-fat glass into a tall-skinny glass, that the amount of water remains the same. Children usually develop this ability — called conservation — by age seven. In the study, white children of the target age who had more difficulty noticing that the amount of water stayed the same were more likely to hold negative views of black children (Herbert).
Thinking in the abstract takes intelligence. Thinking in the abstract entails the ability to recognize that things which appear to be different may in reality be the same. For example, it is because we can think abstractly that we can recognize that snow, water, and steam, despite appearances, are all the same substance. H2O is the abstraction of water.
Things which appear on the surface to be different may in reality be identical. Four quarters make a dollar; and a short-fat glass can be the equivalent of a tall-skinny glass. Reality and appearance are not the same, which confuses our more dim-witted fellows. On the surface, people appear different. Some are dark, and some are light. So they must be different, right? After all, we have a word for these differences: race.
Let’s dismantle the word race, and expose it for the fraud it is. And let us begin this dismantling by examining the whale, which, on first glance, appears to be a fish. We once called whales fish, despite several anomalies. Here are two key anomalies which led scientists to say that’s strange. First, whales birth their young live. Second, they have horizontal tails. Fish lay eggs and have vertical tails.
Focusing on these anomalies, scientists discovered that whales and dolphins and porpoises have more in common with people than with fish, despite appearances. We find evidence for this in their spines. Whale spines, like our spines, bend forward and backward. Fish spines, unlike our spines, bend side to side. Whales once walked on land, and were wolf-like creatures. Notice in this image of the early whale called dorudon that it had hind legs — for walking (“The Evolution of Whales”).
Things which appear to be the same may be in reality quite different; things which appear quite different may in reality be quite similar. And things which appear to be different may in the abstract be the same. Whales and dolphins are not fish; they are mammals, like us.
People appear to be different; and so we use the word race as if there are in reality different species of humans. There are not. Scout is right. “[T]here’s just one kind of folks. Folks” (Harper, 304).
Closer inspection proves that the word race points to a mere shadow, not to a reality. Like the people in Plato’s Cave of Ignorance, racists take pride in how they name shadows. Often, they name shadows with dehumanizing words — like the N-word. So let us cut to the chase. There is only one species of human: homo sapiens.
Understanding what a species is entails an understanding of sex. Species are distinguished from one another along reproductive lines. To have a baby requires that a sperm and an egg would successfully combine to create an individual, who could, on average, reproduce. That is, the DNA of the father and mother must be of a common kind. A hippo and a housecat cannot breed. The hippo is therefore a different species from a housecat.
Yet there are species who are nearly the same species, such as the lion and the tiger. Only about 5 million years ago, lions and tigers were the same species. Then two groups of this species got isolated and did not interbreed. Slowly, they became lions and tigers. But five million years is short in evolutionary terms; so the DNA of lions and tigers only slightly differs. With some difficulty can interbreed lions and tigers, and get the biggest cat in the world: the liger. What we cannot do is get a second generation. So lions and tigers are as near as two species can be to one another while yet remaining different species.
Humans from any part of the world can easily have children with humans from any other part of the world; and those children can easily grow up and easily have children with humans from any part of the world. Humans are not genetically diverse. Our genetic family ties are tight.
Humans have had little time to genetically drift from one another. Roughly 70,000 years ago, humans almost went extinct. We lost most of our genetic diversity. All people can trace their family tree to a population in Africa between of fewer than 10,000 individuals (“Humans”). We are all Africans.
Whereas lions and tigers have had five million years to drift apart, we have only had 70,000 years — an evolutionary eye-blink. That’s the difference between a seventy-one yard rush and a one-yard rush. Inside of a yard, a fullback can only do so many spins, tucks and turns.
In order to become separate species, we would have to remain isolated from one another for millions and millions and millions of years. I prefer to travel. And having travelled much, I have seen many of my friends fall in love with people from other cultures. I have seen whites marry blacks, blacks marry asians, and asians marry whites. In every case, the result was the same: kids.
Though people appear quite different, we are very much the same. There is no single gene that distinguishes, say, Japanese from French (Roach). And having two beautiful children of my own from an intercultural marriage, I can attest that only ideas separate people.
Not all ideas are equal. Some ideas are plain stupid. Stupid ideas cannot stand once we know the facts — unless we choose to ignore the facts. But what intelligent person would choose to be ignorant? What intelligent person would prefer to remain in The Cave of Ignorance? None but a caveman.
Here is why this all matters: we are a nation of laws. Not many would argue that cows should get equal protection under the law — this is because cows are a different species. We are equal before the law because we are equally human. This is the great idea which makes America exceptional: we are all created equal. The evidence is in our DNA.
Yet in the United States, we have a history of treating people who look different as less than human. As we read To Kill a Mockingbird, keep this in mind: we are equal before the law because we are equal in our humanity. Atticus Finch will prove to be a fine man who recognizes the humanity in others, and practices law according to this deep principal.
To understand the superficial differences between people, consider the following. As our ancestors migrated out of Africa, they adapted to different environments. Being human, they used the UV-B rays in sunlight to create vitamin D in their skin. We all need vitamin D. So, as they travelled north, where there is less UV-B radiation, their skin lightened. That way, they were able to get the more UV-B rays to synthesize the vitamin D they needed. It is a tradeoff: less UV protection for more vitamin D.
This adaptation in no way made them more or less human. We’ve been fully human for about 200,000 years (Avasthi).
Humans who migrated farther north got less UV light, and so grew more lightly pigmented — whiter. That’s it. It doesn’t take a genius to figure it out.
