   Endemism and Isolation Metrics
   Archipelagos serve as natural laboratories for evolutionary biology, driving high rates of endemic speciation due to geographic isolation. However, this isolation also renders endemic populations acutely vulnerable to external pressures.
   The Degree of Naïve Endemism ($DNE$) is often calculated using the formula:

   Geographic Isolation and Vicariance
   Geographic isolation is the fundamental prerequisite for most speciation events resulting in endemism. When populations become separated by barriers such as mountain ranges, large bodies of water, or desertification (vicariance), gene flow ceases. Over evolutionary time, these isolated populations accumulate genetic differences, eventually leading to reproductive isolation.

3. Zagros Mountains

   Linked via "geographic isolation"

   Human Geography and Cultural Zonation
   The ethno-linguistic diversity of the Zagros Mountains region is extensive, reflecting millennia of geographic isolation imposed by the mountain range. Major ethnic groups include the Kurds, Lurs, Bakhtiari, and Qashqai. The difficult terrain has historically limited large-scale [infrastructural development](/entries/infrastructural-development…
