Theodosius Dobzhansky Zitate

Theodosius Dobzhansky war ein russisch-US-amerikanischer Genetiker, Zoologe und Evolutionsbiologe, der zusammen mit Ernst Mayr als einer der führenden Vertreter der synthetischen Evolutionstheorie gilt, welche die Genetik mit der Evolutionstheorie vereinigte.

Dobzhansky leistete entscheidende Beiträge zum Verständnis der biologischen Evolution und der Entstehung der Arten. Er war nicht nur ein großer Evolutionstheoretiker, sondern auch ein bedeutender Experimentator. Bekannt wurde er durch seine genetischen Forschungen über die Taufliege Drosophila melanogaster.

Theodosius Dobzhansky Zitate und Sprüche

„Jede Person hat einen Genotyp und eine Lebensgeschichte, die sich von jedem anderen Wesen unterscheiden, sei es von einem Mitglied der Familie, des Clans, der Rasse oder der Menschheit. Über die universellen Rechte aller menschlichen Wesen hinaus (was eine typologische Zuschreibung sein kann!), sollte eine Person aufgrund seiner eigenen Verdienste bewertet werten.“

Theodosius Dobzhansky

“Seen in the light of evolution, biology is, perhaps, intellectually the most satisfying and inspiring science. Without that light it becomes a pile of sundry facts -- some of them interesting or curious but making no meaningful picture as a whole.”

About

“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.”

Mourning and Funerals—For Whom (1977)

“No known human group... simply throw[s] out its dead without any ritual or ceremony. In stark contrast, no animal practices burial of dead individuals of its own species.”

Mourning and Funerals—For Whom (1977)

“According to Goldschmidt, all that evolution by the usual mutations—dubbed "micromutations"—can accomplish is to bring about "diversification strictly within species, usually, if not exclusively, for the sake of adaptation of the species to specific conditions within the area which it is able to occupy." New species, genera, and higher groups arise at once, by cataclysmic saltations—termed macromutations or systematic mutations—which bring about in one step a basic reconstruction of the whole organism. The role of natural selection in this process becomes "reduced to the simple alternative: immediate acceptance or rejection." A new form of life having been thus catapulted into being, the details of its structures and functions are subsequently adjusted by micromutation and selection. It is unnecessary to stress here that this theory virtually rejects evolution as this term is usually understood (to evolve means to unfold or to develop gradually), and that the systematic mutations it postulates have never been observed. It is possible to imagine a mutation so drastic that its product becomes a monster hurling itself beyond the confines of species, genus, family, or class. But in what Goldschmidt has called the "hopeful monster" the harmonious system, which any organism must necessarily possess, must be transformed at once into a radically different, but still sufficiently coherent, system to enable the monster to survive. The assumption that such a prodigy may, however rarely, walk the earth overtaxes one's credulity, even though it may be right that the existence of life in the cosmos is in itself an extremely improbable event.”

“Does the evolutionary doctrine clash with religious faith? It does not. It is a blunder to mistake the Holy Scriptures for elementary textbooks of astronomy, geology, biology, and anthropology. Only if symbols are construed to mean what they are not intended to mean can there arise imaginary, insoluble conflicts. As pointed out above, the blunder leads to blasphemy: the Creator is accused of systematic deceitfulness.”

"Nothing in Biology Makes Sense Except in the Light of Evolution" (1973)

“The evolution of life, and the evolutionary origin of mankind, are scientifically established as firmly and completely as any historical event not witnessed by human observers. Any concession to anti-evolutionists, suggesting that there are scientific reasons to doubt the facticity of evolution, would be propagating a plain untruth.”
