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.
