T (1937) Genetic nature of species differences.
Petersburg State University, Theodosius Dobzhansky
Center for Genome Bioinformatics, 41 Sredniy Prospect, St.
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).
The reader must look up Dobzhansky
, Haldane, Penrose and Mayr.
Finalmente, "nada em biologia faz sentido exceto a luz da evolucao" (DOBZHANSKY
, 1973), e a Ecologia nao escapa a essa afirmacao.
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." March will be represented by articles from the 1940s, April by the 1950s, May the 1960s, August the 1970s, September the 1980s, October the 1990s, and the November/December issue the 2000s.
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
