Theodosius Dobzhansky quotes
Theodosius Dobzhansky was a Ukrainian-American geneticist and evolutionary biologist, regarded as one of the founders of modern evolutionary synthesis. His research on fruit flies demonstrated the role of genetics in evolution and underscored the importance of genetic diversity. He greatly influenced evolutionary biology, and he famously stated, “Nothing in biology makes sense except in the light of evolution.” Here are 10 of his quotes:
Between 1937 and 1941, Dobzhansky went from being able to allow for the possibility of evolutionary mechanisms other than those he favored to a position in which everything that did not fit his definition of evolution was rejected.
In the midst of his outpouring of anger at and dismissal of Goldschmidt, Dobzhansky neglected to consider the fact that while Goldschmidt's systemic mutations may not have been observed, neither had the mechanisms of speculation that he, or anyone else, for that matter, had proposed. ...it was and still is the case that, with the exception of Dobzhansky's claim about a new species of fruit fly, the formation of a new species, by any mechanism, has never been observed.
