Webin each parental lineage [3]. The Dobzhansky-Muller model is agnostic with respect to why causal genes diverge, but evidence from several studies in Drosophila suggests that hybrid incompatibility may arise as a by-product of adaptive evolution, since the few known incompatibility genes are all rapidly evolving [5–7].
