Data from: Ecological opportunities and specializations shaped genetic divergence in a highly mobile marine top predator
Environmental conditions can shape genetic and morphological divergence. Release of new habitats during historical environmental changes was a major driver of evolutionary diversification. Here, forces shaping population structure and ecotype differentiation (‘pelagic’ and ‘coastal’) of bottlenose d...

Environmental conditions can shape genetic and morphological divergence. Release of new habitats during historical environmental changes was a major driver of evolutionary diversification.

We suggest that ecological opportunity to specialize is a major driver of genetic and morphological divergence.
