Drosophila pseudoobscura
Drosophila pseudoobscura is a species of fruit fly, used extensively in lab studies of the genetics of natural populations.
It was first used by Theodosius Dobzhansky and his colleagues. They collected samples from populations in western North America and Mexico, and grew them in 'population cages' in the laboratory. They were interested in natural selection, genetic drift, and other aspects of population genetics.[1][2][3]
In 1989 Diane Dodd gave laboratory populations of D. pseudoobscura two different food types, starch and maltose. They rapidly evolved into two distinct groups after only eight generations with the different foods.[5] Dodd's experiment has been repeated by others, and works with other kinds of fruit flies and foods.[6]
In 2005, D. pseudoobscura was the second Drosophila species to have its genome sequenced, after Drosophila melanogaster.[7]
