In 1933, Dobzhansky began studying the population genetics of the fruit flies, Drosophila pseudoobscura. His results and conclusions, published in his 1937 work “Genetics and the Origin of Species”, turned out to be the most important book on evolutionary biology of the 20th century.
When did Lynn Margulis make her discovery?
She formulated the symbiotic theory of evolution (SET), which deals with the interconnection of prokaryotic and eukaryotic cells (cells with nuclei), explaining the emergence of new species by a mechanism known as “symbiogenesis”. She published her theory in her book, “Origin of Eukaryotic Cells (1970)” in 1970.
What did David Dobzhansky do for evolution?
Dobzhansky was born in Ukraine, then part of the Russian Empire, and became an immigrant to the United States in 1927, aged 27.
