Abstract
Rausher's assertion that divergent selection across a hybrid zone is incompatible with adaptive ridges, although intuitively reasonable, is incorrect on several fronts. His alternative hypothesis of a single moveable peak predicts a sharp environmental transition across the hybrid zone that is not supported by observations. Thus, a high fitness path still provides the most straightforward explanation of our data.
