Hypothetical scenarios for the emergence of the observed pattern of subpopulations and ecotypes of Nasonia vitripennis. Scenario A Inbreeding lines evolve into subpopulations in sympatry and become independently adapted to their respective microhabitats. Scenario B Inbreeding lines evolve into two subpopulations in sympatry. One subpopulation becomes adapted to bird nests as microhabitat and one subpopulation becomes adapted to carrion. Subsequently, the carrion subpopulations splits up into 2 or 4 separate subpopulations. Scenario C Subpopulations became adapted to their respective microhabitats in allopatry and become sympatric by immigration into the study area
