(dəb-zhăn′skē), Theodosius 1900-1975.
Russian-born American geneticist. His Genetics and the Origin of the Species (1937) synthesized Mendel's laws of heredity and Darwinian theory. He is also known for his study of the fruit fly Drosophilia, which showed a large degree of genetic variation within a population.

Fodor and Piattelli-Palmarini assert that such recent developments as evo-devo somehow undermine the statement of legendary neo-Darwinist Theodosius Dobzhansky that "nothing in biology makes sense except in light of evolution," So far as I know, all the researchers the authors cite would side with Dobzhansky by asserting that nothing in their work makes sense except in light of evolution.
Al respecto Dunn y Dobzhansky en el libro Herencia, raza y sociedad afirman: "De la aceptacion de las diferencias individuales a la aceptacion de las diferencias entre grupos solo hay un paso; y la mayor parte de los pueblos, tanto primitivos como civilizados, tienen clara conciencia de sus diferencias con respecto a otros pueblos" (1975, p.
Among his perspectives are mathematical and philosophical biologist Haldane weighs, in, Huxley proclaims a new synthesis, chromosome inversions in Drosophila, the changing views of Dobzhansky and Wright, and whether evolutionary theory is scientific.
Mutual interest may occur if the courtship enhances reproductive isolation (Mayr 1963; Dobzhansky 1970) by providing cues for species recognition (Ryan 1985; Andersson 1994) or if a long courtship is necessary to stimulate the female into mate (see reviews in Platnick 1971; Robinson 1982).
De acuerdo con la ya clasica definicion de Dobzhansky (1955), las razas son poblaciones que difieren en la frecuencia de ciertos genes, y que intercambian o tienen la posibilidad de intercambiar genes a traves de las fronteras, generalmente geograficas, que las separan.
Under the influence of Andres Dreyfus, a master of Brazilian genetics at the University of Sao Paulo (USP) and by his colleague Theodosius Dobzhansky, from Columbia University, Pavan oriented his professional activity towards the study of the mysteries of the genes and their use for the benefit of mankind.
At both ends of the new Jordan Science Hall on the Notre Dame campus, engraved in large medallions in the floor, is an often repeated statement of geneticist Theodosius Dobzhansky (1900-75), published 2 y before his death: "Nothing makes sense in biology except in the light of evolution" (Dobzhansky 1973).
In his classic article entitled "Nothing in Biology Makes Sense Except in the Light of Evolution," (4) the great population geneticist and a primary architect of the modern evolutionary synthesis, Theodosius Dobzhansky, made this point succinctly: "Seen in the light of evolution, biology is, perhaps, intellectually the most satisfying and inspiring science.
Theodosius Dobzhansky, one of the great evolutionary geneticists of the 20th century, was a professing Christian, as are scientists like Francis Collins, who directed the Human Genome Project.
As geneticist Theodosius Dobzhansky once so aptly proclaimed, "Nothing makes sense in biology except in the light of evolution.
