Biography

Early life

Dobzhansky was born on January 25, 1900 in Nemyriv, Ukraine. An only child, his father Grigory Dobzhansky was a mathematics teacher, and his mother was Sophia Voinarsky.[1] In 1910 the family moved to Kiev, Ukraine. At high school, Dobzhansky collected butterflies and decided to become a biologist.[2] In 1915, he met Victor Luchnik who convinced him to specialise on beetles instead. Dobzhansky attended the University of Kiev between 1917 and 1921, where he then studied until 1924. He then moved to Leningrad, Russia, to study under Yuri Filipchenko, where a Drosophila melanogaster lab had been established. is the 25th day of the year in the Gregorian calendar. ...

America

Dobzhansky emigrated to the United States in 1927 on a scholarship from International Education Board of the Rockefeller Foundation arriving in New York on December 27. He worked with Thomas Hunt Morgan at Columbia University, who had pioneered the use of fruit flies (Drosophila melanogaster) in genetics experiments. He followed Morgan to the California Institute of Technology from 1930 to 1940. Dobzhansky is credited for having taken fruit fly research out of the laboratory and "into the field", having discovered that different regional varieties of flies were more similar to each other genetically than to flies from other regions.

In 1937 he published one of the major works of the modern evolutionary synthesis, the synthesis of evolutionary biology with genetics, entitled Genetics and the Origin of Species, which amongst other things defined evolution as "a change in the frequency of an allele within a gene pool". Also in 1937, he became a naturalized citizen of the United States. During this time he had a very public falling out with one of his Drosophila collaborators, Alfred Sturtevant, based primarily in professional competition.

Meanwhile, he continued working and published a famous essay "Nothing in Biology Makes Sense Except in the Light of Evolution".
