Mendel’s Genetic Revolution and the Legacy of Scientific Racism

In July, the world celebrated 200 years since the birth of Gregor Mendel, who is widely accepted as the “father of modern genetics” for his discovery of the laws of inheritance. His experiments with peas, published in 1866 under the title “Experiments in Plant Hybridization,” identified dominant and recessive traits and how recessive traits would reappear in future generations and in what proportion. His work would largely remain unacknowledged and ignored until three other biologists replicated his work in 1900.

While Mendel’s work is central to modern genetics, and his use of experimental methods and observation is a model for science, it also set off the dark side with which genetics has been inextricably linked: eugenics and racism. But eugenics was much more than race “science.” It was also used to argue the superiority of the elite and dominant races, and in countries like India, it was used as a “scientific” justification for the caste system as well.

People who believe that eugenics was a temporary aberration in science and that it died with Nazi Germany would be shocked to find out that even the major institutions and journals that included the word eugenics as part of their names have continued to operate by just changing their titles. The Annals of Eugenics became the Annals of Human Genetics; the Eugenics Review changed its name to the Journal of Biosocial Science; Eugenics Quarterly changed to Biodemography and Social Biology; and the Eugenics Society was renamed the Galton Institute. Several departments in major universities, which were earlier called the department of eugenics, either became the department of human genetics or the department of social biology.

All of them have apparently shed their eugenics past, but the reoccurrence of the race and IQ debate, sociobiology, the white replacement theory and the rise of white nationalism are all markers that theories of eugenics are very much alive. In India, the race theory takes the form of the belief that Aryans are “superior” and fair skin is seen as a marker of Aryan ancestry.

While Adolf Hitler’s gas chambers and Nazi Germany’s genocide of Jews and Roma communities have made it difficult to talk about the racial superiority of certain races, scientific racism persists within science. It is a part of the justification that the elite seek, justifying their superior position based on their genes, and not on the fact that they inherited or stole this wealth. It is a way to airbrush the history of the loot, slavery and genocide that accompanied the colonization of the world by a handful of countries in Western Europe.

Why is it that when we talk about genetics and history, the only story that is repeated is that about biologist Trofim Lysenko and how the Soviet Communist Party placed ideology above science? Why is it that the mention of eugenics in popular literature is only with respect to Nazi Germany and not about how Germany’s eugenic laws were inspired directly by the U.S.? Or how eugenics in Germany and the U.S. were deeply intertwined? Or how Mendel’s legacy of genetics become a tool in the hands of racist states, which included the U.S. and Great Britain? Why is it that genetics is used repeatedly to support theories of superiority of the white race?

Mendel showed that there were traits that were inherited, and therefore we had genes that carried certain markers that could be measured, such as the color of the flower and the height of the plant. Biology then had no idea of how many genes we had, which traits could be inherited, how genetically mixed the human population is, etc. Mendel himself had no idea about genes as carriers of inheritance, and this knowledge became known much later.

From genetics to society, the application of these principles was a huge leap that was not supported by any empirical scientific evidence. All attempts to show the superiority of certain races started with a priori assuming that certain races were superior and then trying to find what evidence to choose from that would help support this thesis. Much of the IQ debate and sociobiology came from this approach to science. In his review of The Bell Curve, Bob Herbert wrote that the authors, Charles Murray and Richard Herrnstein, had written a piece of “racial pornography,” “…to drape the cloak of respectability over the obscene and long-discredited views of the world’s most rabid racists.”

A little bit of the history of science is important here. Eugenics was very much mainstream in the early 20th century and had the support of major parties and political figures in the UK and the U.S. Not surprisingly, former British Prime Minister Winston Churchill was a noted supporter of race science, although eugenics had some supporters among progressives as well.

The founder of eugenics in Great Britain was Francis Galton, who was a cousin of Charles Darwin. Galton pioneered statistical methods like regression and normal distribution, as did his close collaborators and successors in the Eugenics Society, Karl Pearson and R.A. Fisher. On the connection of race and science, Aubrey Clayton, in an essay in Nautilus, writes, “What we now understand as statistics comes largely from the work of Galton, Pearson, and Fisher, whose names appear in bread-and-butter terms like ‘Pearson correlation coefficient’ and ‘Fisher information.’ In particular, the beleaguered concept of ‘statistical significance,’ for decades the measure of whether empirical research is publication-worthy, can be traced directly to the trio.”

It was Galton who, based supposedly on scientific evidence, argued for the superiority of the British over Africans and other natives, and that superior races should replace inferior races by way of selective breeding. Pearson gave his justification for genocide: “History shows me one way, and one way only, in which a high state of civilization has been produced, namely the struggle of race with race, and the survival of the physically and mentally fitter race.”

The eugenics program had two sides: one was that the state should try to encourage selective breeding to improve the stock of the population. The other was for the state should take active steps to “weed out” undesirable populations. The sterilization of “undesirables” was as much a part of the eugenics societies as encouraging people toward selective breeding.

In the U.S., eugenics was centered on Cold Spring Harbor’s Eugenics Record Office. While Cold Spring Harbor Laboratory and its research publications still hold an important place in contemporary life sciences, its original significance came from the Eugenics Record Office, which operated as the intellectual center of eugenics and race science. It was supported by philanthropic money from the Rockefeller family, the Carnegie Institution and many others. Charles Davenport, a Harvard biologist, and his associate Harry Laughlin became the key figures in passing a set of state laws in the U.S. that led to forced sterilization of the “unfit” population. They also actively contributed to the Immigration Act of 1924, which set quotas for races. The Nordic races had priority, while East Europeans (Slavic races), East Asians, Arabs, Africans and Jews were virtually barred from entering the country.

Sterilization laws in the U.S. at the time were controlled by the states. U.S. Supreme Court Justice Oliver Wendell Holmes, the doyen of liberal jurisprudence in the U.S., gave his infamous judgment in Virginia on justifying compulsory sterilization, “Three generations of imbeciles are enough,” he ruled in Buck v. Bell. Carrie Buck and her daughter were not imbeciles; they paid for their “sins” of being poor and perceived as threats to society (a society that failed them in turn). Again, Eugenics Research Office and Laughlin played an important role in providing “scientific evidence” for the sterilization of the “unfit.”

While Nazi Germany’s race laws are widely condemned as being the basis for Hitler’s gas chambers, Hitler himself stated that his inspiration for Germany’s race laws was the U.S. laws on sterilization and immigration. The close links between the U.S. eugenicists and Nazi Germany are widely known and recorded. Edwin Black’s book War Against the Weak: Eugenics and America’s Campaign to Create a Master Race described how “Adolf Hitler’s race hatred was underpinned by the work of American eugenicists,” according to an article in the Guardian in 2004. The University of Heidelberg, meanwhile, gave Laughlin an honorary degree for his work in the “science of racial cleansing.”

With the fall of Nazi Germany, eugenics became discredited. This resulted in institutions, departments and journals that had any affiliation to eugenics by name being renamed, but they continued to do the same work. Human genetics and social biology became the new names for eugenics. The Bell Curve was published in the 1990s justifying racism, and a recent bestseller by Nicholas Wade, a former science correspondent of the New York Times, also trot out theories that have long been scientifically discarded. Fifty years back, Richard Lewontin had shown that only about 6 to 7 percent of human genetic variation exists between so-called racial groups. At that time, genetics was still at a nascent stage. Later, data has only strengthened Lewontin’s research.

Why is it that while criticizing the Soviet Union’s scientific research and the sins of Lysenko 80 years back, we forget about race science and its use of genetics?

The answer is simple: Attacking the scientific principles and theories developed by the Soviet Union as an example of ideology trumping science is easy. It makes Lysenko the norm for Soviet science of ideology trumping pure science. But why is eugenics, with its destructive past and its continuing presence in Europe and the U.S., not recognized as an ideology—one that has persisted for more than 100 years and that continues to thrive under the modern garb of an IQ debate or sociobiology?

The reason is that it allows racism a place within science: changing the name from eugenics to sociobiology makes it appear as a respectable science. The power of ideology is not in the ideas but in the structure of our society, where the rich and the powerful need justification for their position. That is why race science as an ideology is a natural corollary of capitalism and groups like the G7, the club of the rich countries who want to create a “rule-based international order.” Race science as sociobiology is a more genteel justification than eugenics for the rule of capital at home and ex-colonial and settler-colonial states abroad. The fight for science in genetics has to be fought both within and outside science as the two are closely connected.
