Genetic evidence for adaptation-driven incipient speciation of Drosophila melanogaster along a microclimactic contrast in "Evolution Canyon," Israel

Substantial genetic differentiation, as great as among species, exists between populations of Drosophila melanogaster inhabiting opposite slopes of a small canyon. Previous work has shown that prezygotic sexual isolation and numerous differences in stress-related phenotypes have evolved between D. m...

Summary:Substantial genetic differentiation, as great as among species, exists between populations of Drosophila melanogaster inhabiting opposite slopes of a small canyon. Previous work has shown that prezygotic sexual isolation and numerous differences in stress-related phenotypes have evolved between D. melanogaster populations in "Evolution Canyon," Israel, in which slopes 100-4-- m apart differ dramatically in aridity, solar radiation, and associated vegetation.
