	Theodosius Dobzhansky
		Theodosius Dobzhansky was born on January 25, 1900, in the town of Nemirov, Russia.
		By age twelve, Dobzhansky already knew what he wanted to be and later told people that "there was no question that I wanted to become a biologist" and he planned to study nature science in the University of Kiev.
		Dobzhansky's studies in population genetics served as a basis for his explanation of how the evolution of races and species could have come about through adaptation.

		Theodosius I or Theodosius the Great, 346?-395, Roman emperor of the East (379-95) and emperor of the West (394-95), son of Theodosius, the general of Valentinian I. He became (375) military governor of Moesia, but following the execution (376) of his father he retired to Spain.
		Theodosius, whom Gratian made co-augustus in 379, took up arms against the Visigoths, who were plundering the Balkan Peninsula.
		In 383, Gratian was murdered; Theodosius was forced to recognize the usurper, Maximus, as emperor in the West outside Italy, where Gratian's brother and legal successor, Valentinian II, held authority.

		Dobzhansky was quite surprised, then, to find evidence that the inversion differences were adaptively significant after all, which led him to explore a range of variation-maintaining forms of natural selection.
		Dobzhansky and Muller were also at the center of controversies in the 1950s - early 1970s concerning the impact of radiation-induced mutation from atomic weapons tests (both men received considerable funding from the Atomic Energy Commission during this period).
		Dobzhansky’s understanding of the religious/moralistic significance of intraspecific variation also reflected his Russian heritage, although this influence has been more difficult to reconstruct, and many of the same concerns--like the evils of natural selection--had also been raised in the Anglo-American context (e.g., by the atheist T.H. Morgan, in conversations with Dobzhansky).

		Dobzhansky, cannot be understood as a purely biological process, nor can it be adequately described as a history of culture; rather, it is the interaction between the two components of evolution—the biological, or organic, and the cultural, or superorganic.
		Dobzhansky points out, has not annulled the organic; and human welfare, both in individuals and in societies, is predicated upon the health of the genetic endowment of human population.
		Dobzhansky expounds the thesis that the genetic basis of culture should be improved, or at the very least should not be allowed to deteriorate.

		Dobzhansky had strong opinions about current political issues, and especially the effect of politics on the freedom of scientists to pursue their work.
		Correspondence between Dobzhansky and his Russian colleagues was severely restricted by Soviet authorities for many years, nevertheless he was able to reestablish contact with several of them in the late 1960s, and approximately 175 letters in Russian are preserved in the collection.

	Theodosius Dobzhansky - EvoWiki
		Dobzhansky was one of the principal engineers of the modern synthesis which united genetics and evolution, notably holding a gene-centric view, defining evolution as a change in allele frequencies in a gene pool.
		Dobzhansky was also a tireless critic of Creationism, most famously in his 1973 essay Nothing in biology makes sense except in the light of evolution, the title of which has become one of the most quoted anti-Creationist lines.
		Dobzhansky was a Russian orthodox Christian and a proponent of Theistic Evolution.

		Theodosius Dobzhansky, a Russian geneticist who moved to the United States, provided laboratory evidence for natural selection and variation where previously there had been only field observation.
		Dobzhansky moved to the United States in 1927, and, through his lifelong experiments with fruit flies, showed that natural populations of the flies exhibited the same kinds of genetic variations that could be produced artificially by mutation in the laboratory.
		Dobzhansky is remembered today not only for his strictly scientific achievements, but also for his deep concern about the possible misunderstanding and misuse by society of the concepts of genetic variation.

	Poroi 1, 1, Ceccarelli
		A close look at the substance of Wilson’s and Dobzhansky’s books reveals that, although Wilson wrote with the advantage of the more advanced state of knowledge in genetics available to a scientist in the late 1990s, the two authors were really not all that far apart in their substantive understanding of the evolution of behavior.
		Somehow, Dobzhansky was able to steer a course between the two extremes, drawing both unconverted biologists and social scientists into the new study, while Wilson only angered those who were not already converts to his cause.
		Dobzhansky’s theme of balance was in marked contrast to this rhetoric of directionality and hierarchy, and I believe it did much to persuade his readers to accept his call to action.

		Dobzhansky's studies in population genetics served as a basis for his explanation of how the evolution of races and species could have come about through adaptation.
		His key discovery was that successful species tend to harbor a large pool of genes which allows them to survive and adapt effectively in the event of environmental change.

		To Dobzhansky, the fruit fly chromosomes were a godsend and he spent years in the Californian wilderness collecting flies for analysis in the laboratory.
		In accumulating genetic differences, Dobzhansky saw how two populations might also accumulate differences in body size, colour, genital architecture, behavioural idiosyncrasies, and a thousand other characteristics that could eventually make them reluctant or unable to mate with one another.
		Dobzhansky had shown what was possible when scientists were willing to abandon their prejudices and break with tradition.

		Dobzhansky published a steady, prolific stream of reports on hybrid sterility, developmental rates, genetic responses to environmental change, and the dispersion rates of genetic populations, the forces of natural selection in the laboratory cages used so extensively at this time, and the interaction of the evolutionary forces (natural selection, mutation, migration, and genetic drift).
		Dobzhansky hoped that after retirement as a professor, he would still be permitted to retain his laboratory at the Rockefeller University and to work with his graduate students.

		Dobzhansky disagreed with Grassé fundamentally, but he acknowledged at the outset that his French counterpart knew as much about the scientific evidence regarding animal evolution as anyone in the world.
		To Dobzhansky, therefore, Grassé's insistence that the sources of new genetic information might be a mystery to our science was pointless and harmful to the cause of science.
		Dobzhansky's fruitfly variations constitute evolution, and evolution is also the grand creative process that produced fruitflies and human beings in the first place.

		Stebbins met Dobzhansky on a visit to the California Institute of Technology in the spring of 1936 when Dobzhansky was just beginning to turn to his work on the genetics of natural populations using Drosophila pseudoobscura.
		The friendship with Dobzhansky was to prove absolutely critical to Ledyard as his own interests were shifting more and more to evolutionary genetics, thanks to the teaching demands made by the evolution course.
		Dobzhansky, who published his own pat h-breaking synthesis of evolutionary genetics under the title Genetics and the Origin of Species in 1937, began to foster Ledyard's evolutionary interests (4).

		Dobzhansky starts with a reductio ad absurdum of the geocentrism of an Arab sheik (who may have been Shaikh Abdulaziz bin Baz, later the Grand Mufti of Saudi Arabia) who believes the Sun revolves around the Earth because scripture says so.
		Dobzhansky then goes on to describe the diversity of life on Earth, and that the diversity of species cannot be best explained by creationism because of the ecological interactions between them.
		Dobzhansky concludes that scripture and science are two different things: "It is a blunder to mistake the Holy Scriptures for elementary textbooks of astronomy, geology, biology, and anthropology".

	Starting "The Modern Synthesis": Theodosius Dobzhansky
		Dobzhansky, who emigrated to the United States in 1928, worked in Thomas Hunt Morgan's "Fly Room," where mutations were being studied closely for the first time.
		Dobzhansky helped discover that different fruit fly populations have different frequencies of two different versions of the same chromosome; chromosome A might be more frequent in one population while chromosome A' is more frequent in a neighboring population.
		Dobzhansky ran experiments on fruit flies that demonstrated that this incompatibility is caused by specific genes carried by one species that clash with the genes from another species.

		It was Dobzhansky's first book, but he probably would never have found the time to write it if he hadn't been forced to spend weeks in bed after a horseback riding accident.
		Dobzhansky's book was the first systematic overview view encompassing organic diversity, variation in natural populations, selection, isolating mechanisms (a term he coined) and species as natural units.
		Dobzhansky's intimate familiarity with the processes of variation and evolution in these fast-breeding insects also enabled him to apply his methods to understanding variation and change in human populations.
