What was Trofim Lysenko theory?

Lysenko proposed an influence of the body on inheritance similar to Darwin’s pangenesis theory, that every part of the body emits tiny gemmules which migrate to the gonads and are transferred to offspring. Gemmules were thought to develop into their associated body parts as offspring matures.

Who is Trofim Lysenko?

His hardscrabble background—people called him the “barefoot scientist”—also made him popular within the Communist party, which glorified peasants. 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.

Why was Lysenko against genetics?

Progress in genetics and evolutionary biology in the young Union of Soviet Socialist Republics (USSR) was hindered in the 1930s by the agronomist Trofim Lysenko, who believed that acquired traits are inherited, claimed that heredity can be changed by “educating” plants, and denied the existence of genes.
