Today’s interesting fact has to do with Trofim Lysenko, Jean-Baptiste Lamarck and the theory of the heritability of acquired characteristics.

Lysenko was a follower of Lamarck, a French Biologist who came up with Lamarckism, or the idea that an organism can pass on traits that it develops during its life, to its descendants. These traits were thought to be passed on at the time of conception.

Lamarckism fell out of favour in the 1920’s when evidence that seemed to support the theory, was shown to have been tampered with.

Lysenko claimed to have developed a better agricultural system through Lamarckism, which the leaders of the Soviet Union felt better supported the ideology of Communism. Lysenko was placed in charge of agriculture and denounced biologists that suggested other systems might work better than Lysenkoism, particularly geneticists, many of whom were executed or sent to labour camps.

Genetics was eventually declared a pseudoscience and effectively outlawed, and this was rescinded only in the mid 1960s.
