Trofim Lysenko and genetics in Soviet Russia (1927-1962):  Trofim Lysenko and genetics in Soviet Russia (1927-1962) Bibliography V. Soifer, Lysenko and the tragedy of Soviet science, Rutgers, 1994 D. Joravsky, The Lysenko affair, Cambridge University Press,1970 W. Gratzer, The undegrowth of science, Oxford University Press, 2000 Genetics:  Genetics the branch of biology that studies heredity and variations in living organisms I will discuss how genetics was declared a pseudo-science in a large country for more than thirty years We will also try to understand the reasons behind this unfortunate story Timeline:  Timeline Darwin 1790 1830 1910 1930 1810 1950 1850 1870 1890 1920 1940 1960 Charles Robert Darwin:  (1809-1882) Formulated the evolution theory in his book “The Origin of Species” “… in the struggle for existence, …, favourable variations would tend to be preserved, and unfavourable ones to be destroyed. The results of this would be the formation of a new species.” Charles Robert Darwin Darwin 1790 1830 1910 1930 1810 1950 1850 1870 1890 1920 1940 1960 How are structural changes passed from one generation to another? Jean-Baptiste Lamarck (1744-1829):  Lamarck Darwin 1790 1830 1910 1930 1810 1950 1850 1870 1890 1920 1940 1960 Jean-Baptiste Lamarck (1744-1829) Developed a classification of animals and plants based on their structural characteristics Suggested that hereditary changes accumulate during the lifetime of an organism under the influence of environmental stimuli These accumulated changes are then passed to the next generation Gregor Mendel    (1822-1884) :  Darwin 1790 1830 1910 1930 1810 1950 1850 1870 1890 1920 1940 1960 Lamarck Mendel Gregor Mendel    (1822-1884)  A monk in a small E. European town & father of genetics Extensively experimented with common plants (peas, etc.) Observed that certain traits do not blend when passed from the parent (pea flowers can be only purple or white, but not a mix) Some of the traits require another trait to be also present Introduced a notion of a “unit of heredity” (gene) Thomas Hunt Morgan (1866-1945):  Darwin 1790 1830 1910 1930 1810 1950 1850 1870 1890 1920 1940 1960 Lamarck Mendel Morgan: chromosome studies 1933 Thomas Hunt Morgan (1866-1945) Discovered that genes are contained in chromosomes Received the Nobel prize in medicine DNA discovery 1953 However, what the gene exactly is was unknown for another twenty years, until the discovery of the DNA molecules Biology in Russia in 1900’s :  World schools in medicine, physiology, zoology, genetics Two Nobel prizes in medicine (Pavlov, 1904; Mechnikov, 1908) The main agricultural producer in Europe Large number of centers of experimental agriculture; two centers of genetics studies (Moscow & St.Petersburg) Biology in Russia in 1900’s 1790 1830 1910 1930 1810 1950 1850 1870 1890 1920 1940 1960 Russian revolution    (November 1917) :  Darwin 1790 1830 1910 1930 1810 1950 1850 1870 1890 1920 1940 1960 Lamarck Mendel DNA discovery 1953 Morgan Russian revolution 1917 Russian revolution    (November 1917)  The conservative monarchy was overthrown by a radical Bolshevik party headed by Vladimir Lenin The new party proclaimed the goal to create a new type of society based on the socialist ideas of Marx and Engels After the death of Lenin, the power was transferred to Josef Stalin, an omnipotent dictator who ruled until 1953 Stalin’s rule The ensuing civil war resulted in millions of deaths, famine, and destruction of the economy Nature of Soviet ideology 1:  Nature of Soviet ideology 1 “Dialectical materialism” -- a philosophy “inspired” by the achievements of modern science Constantly changing matter as a primary form of the existence Consciousness as a particular form of matter Rejection of religion or the ideal laws that exist independently of matter God and “absolute” ideas do not exist The concept of a “gene” seemingly contradicted the Marxist views:  The concept of a “gene” seemingly contradicted the Marxist views Suggested the existence of a unit of “ideal” characteristics (similar to the soul) Disagreed with the perceived infinite divisibility of objects in nature Nature of Soviet ideology 2:  Nature of Soviet ideology 2 Political economy of Karl Marx: all social life can be reduced to economical relations, i.e., material needs of the society Creation of a utopian society without private property on means of production (communism) Abolition of social classes; absolute equality of citizens; creation of a state “where a kitchen maid can rule the country” (V. Lenin) Science in the Soviet Russia :  Russian government tremendously increased the funding of science… …but strictly persecuted deviations from the communist ideology Introduced a party control over industry and science Installed party hardliners on key positions in scientific organizations Was highly suspicious of highly trained scientists Introduced large privileges for workers’ and peasants’ children on college entry exams Science in the Soviet Russia Genetics in the Soviet Russia :  Due to wrong agricultural policies, underproduction was chronic during the first ten years of the new regime The government strongly encouraged the scientists to revive the Russian agricultural school Large investments, support in press, etc. Genetics in the Soviet Russia Nikolai Vavilov, The President of the Russian Agricultural Academy Student of W. Batson, one of the founders of modern genetics Enthusiastic proponent of new agricultural methods and plant breeds Scientists like Vavilov were realistic about what the selection can achieve in just a few years Painstakingly long experiments with many generations of organisms needed to produce new breeds Trofim Lysenko (1898-1976):  Trofim Lysenko (1898-1976) 1898 Born in a peasant family 1917-1925 Higher education in agriculture 1925-1929 Junior researcher in experimental agriculture 1934 Associate member of Russian Academy of Sciences 1939 Full member of the Academy of Sciences 1938 President of the Agricultural academy 1956 Dismissed from the position of the president of the Agricultural academy 1961 Elected the president of the Agricultural academy (the second time) 1964 Dismissed again after the death of Khrushchev Trofim Lysenko scientific views:  Trofim Lysenko scientific views Claimed a method for transforming winter grains into spring grains (vernalization) Based on the ideas similar to the Lamarckan theory of acquired characteristics, denied the existence of genes Darwin 1790 1830 1910 1930 1810 1950 1850 1870 1890 1920 1940 1960 Lamarck Mendel Stalin’s rule Lysenko’s influence Promised astonishing advances in breeding, which were never realized Trofim Lysenko: scientific views:  Trofim Lysenko: scientific views Based on the ideas similar to the Lamarckan theory of acquired characteristics, denied the existence of genes Darwin 1790 1830 1910 1930 1810 1950 1850 1870 1890 1920 1940 1960 Lamarck Mendel Stalin’s rule Lysenko’s influence Promised astonishing advances in breeding and agriculture, which were never realized Was not shy of using statistically incomplete data or sometimes “correct” the data to match expectations In discussions with the opponents, routinely based his arguments on the agreement with the Marxist philosophy Was extremely hostile to applying mathematical methods in biology Miraculous discoveries by Lysenko and his followers:  Miraculous discoveries by Lysenko and his followers Southern plants can be trained to grow in North Could transform rye into wheat and wheat into barley Natural cooperation as a co-existing opposite to natural selection Claimed that song-birds gave birth to cuckoos, and that weeds are transmutations of food grains Bacteria were discovered to emerge from lifeless matter New hybrid chickens emerged from one egg fertilized by several cocks Cows can be coached to produce fatter milk by a “chocolate diet” treatment Suppression of opposition to Lysenko:  Suppression of opposition to Lysenko Lysenko’s movement had a strong support by media and Stalin himself He blamed continual failures on incapability and sabotage by the others He also promoted his “truly communist” science as an opposite to the incapable Western science of “Mendelists-Morganists” Quote:  Quote "The history of Mendel's heredity science demonstrates with a striking clarity the connection between the capitalistic science and all ideological corruption of the bourgeois society." In "Fly lovers, human haters", a newspaper article (1949) Suppression of Lysenko’s opposition:  Suppression of Lysenko’s opposition Through a series of intrigues and highly politicized public “discussions”, he managed to destroy practically all of his opponents More than 3000 biologists were fired, arrested, or executed Nikolai Vavilov was disgracefully dismissed from the presidency of the Agriculture Academy in 1938 and died in prison in 1940 The genetic science in Russia was effectively destroyed until the death of Stalin in 1953 Despite successive failures, Lysenko remained in the leadership of biology and briefly regained the position of the President of the Academy during Khrushchev Analysis: was Lysenko a pseudoscientist?:  Analysis: was Lysenko a pseudoscientist?
