Abstract excerpt

BACKGROUND: Populations that have repeatedly colonized novel environments are useful for studying the role of ecology in adaptive divergence - particularly if some individuals persist in the ancestral habitat. Such "contemporary ancestors" can be used to demonstrate the effects of selection by comparing phenotypic and genetic divergence between the derived population and their extant ancestors. However, evolution...
