Hypothesis
The Marbled White butterfly originated in the Maghreb and colonized Europe via Sicily and Italy.
Conclusion
The study reveals strong genetic differentiation among Marbled White butterfly populations across Europe and the Maghreb, influenced by historical climatic changes.
Supporting Evidence
- Seven distinct genetic lineages of the Marbled White butterfly were identified across Europe and the Maghreb.
- The genetic structures correspond to historical climatic changes and refugia during glacial periods.
- Genetic diversity was highest in Morocco, suggesting it as a potential center of origin for the species.
Takeaway
Scientists studied butterflies to see how they changed and spread over time due to climate changes, finding that different groups of butterflies are very different from each other.
Methodology
The study used allozyme electrophoresis to analyze genetic diversity in 41 populations of Melanargia galathea and one population of M. lachesis.
Limitations
The study may not account for all potential refugia and genetic influences across the entire range of the species.
