Officials eventually put Lysenko in charge of Soviet agriculture in the 1930s. The only problem was, he had batty scientific ideas. In particular, he loathed genetics. Although a young field, genetics advanced rapidly in the 1910s and 1920s; the first Nobel Prize for work in genetics was awarded in 1933. And especially in that era, genetics emphasized fixed traits: Plants and animals have stable characteristics, encoded as genes, which they pass down to their children. Although nominally a biologist, Lysenko considered such ideas reactionary and evil, since he saw them as reinforcing the status quo and denying all capacity for change. (He in fact denied that genes existed.)

Instead, as the journalist Jasper Becker has described in the book Hungry Ghosts, Lysenko promoted the Marxist idea that the environment alone shapes plants and animals. Put them in the proper setting and expose them to the right stimuli, he declared, and you can remake them to an almost infinite degree.

To this end, Lysenko began to “educate” Soviet crops to sprout at different times of year by soaking them in freezing water, among other practices. He then claimed that future generations of crops would remember these environmental cues and, even without being treated themselves, would inherit the beneficial traits. According to traditional genetics, this is impossible: It’s akin to cutting the tail off a cat and expecting her to give birth to tailless kittens. Lysenko, undeterred, was soon bragging about growing orange trees in Siberia, according to Hungry Ghosts. He also promised to boost crop yields nationwide and convert the empty Russian interior into vast farms.

Such claims were exactly what Soviet leaders wanted to hear. In the late 1920s and early 1930s Joseph Stalin—with Lysenko’s backing—had instituted a catastrophic scheme to “modernize” Soviet agriculture, forcing millions of people to join collective, state-run farms. Widespread crop failure and famine resulted. Stalin refused to change course, however, and ordered Lysenko to remedy the disaster with methods based on his radical new ideas. Lysenko forced farmers to plant seeds very close together, for instance, since according to his “law of the life of species,” plants from the same “class” never compete with one another. He also forbade all use of fertilizers and pesticides.

Wheat, rye, potatoes, beets—most everything grown according to Lysenko’s methods died or rotted, says Hungry Ghosts. Stalin still deserves the bulk of the blame for the famines, which killed at least 7 million people, but Lysenko’s practices prolonged and exacerbated the food shortages. (Deaths from the famines peaked around 1932 to 1933, but four years later, after a 163-fold increase in farmland cultivated using Lysenko’s methods, food production was actually lower than before.) The Soviet Union’s allies suffered under Lysenkoism, too. Communist China adopted his methods in the late 1950s and endured even bigger famines. Peasants were reduced to eating tree bark and bird droppings and the occasional family member. At least 30 million died of starvation.
