Data from: Diversifying selection drives parallel evolution of gill raker number and body size along the speciation continuum of European whitefish
Adaptive radiation is the evolution of ecological and phenotypical diversity. It arises via ecological opportunity that promotes the exploration of underutilized or novel niches mediating specialization and reproductive isolation. The assumed precondition for rapid local adaptation is diversifying n...

Adaptive radiation is the evolution of ecological and phenotypical diversity.
