Dob·zhan·sky

(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.

Con la especie como comunidad reproductiva cerrada en la mano, los dos grandes autores del neodarwinismo pudieron llevar a cabo explicaciones precisas acerca de como tiene lugar tanto la adaptacion a un ecosistema como la aparicion de nuevas especiesy,porende,suevolucion, El concepto de especie de Dobzhansky y Mayr ha sido esgrimido en no pocas ocasiones para justificar la existencia por separado de organismos muy proximos entre si, tanto desde el punto de vista genetico como fenotipico, que comparten territorio o, al menos, llegan a coincidir en sus aledanos.

Para dimensionar a importancia da presenca de Theodosius Dobzhansky no Brasil e especificamente junto ao grupo da Universidade de Sao Paulo liderado por AndreDreyfus, um estudo bibliometrico realizado por SIAO (2007) encontrou 90 publicacoes de Dobzhansky e seus colaboradores brasileiros, em aproximadamente 20 periodicos distintos, entre 1943 e 1960.

The genetic distance (D) of Nei (1978) estimates the average number of nucleotide substitutions per locus, detectable by electrophoresis and accumulated in populations since they diverged from a common ancestral, that is, the distance should be proportional to the evolutionary time (DOBZHANSKY et al., 1977; THORPE; SOLE-CAVA, 1994).

In the February evolution issue, you will see Theodosius Dobzhansky's famous article from 1971, "Nothing in biology makes sense except in the light of evolution," and Oscar Riddle's 1938 article "Biology teachers begin to pull together."

Genetic variability confers a species the ability to respond to possible environmental changes, providing a higher capacity to evolve and survive in the long-term (Ayala & Kinger 1980, Dobzhansky et al.
