Question (HOT): "Compare and contrast allopatric and sympatric speciation. Provide a real-world example for each from the Balkan region."

HOT Rjesenje:

"Allopatric speciation occurs via geographic isolation. Example: Dinaric blind cave salamander (Proteus anguinus) – populations isolated in different cave systems across Croatia and Slovenia. Sympatric speciation occurs without geographic isolation, often via polyploidy or niche differentiation. Example: Balkan endemic snails (Albinaria) on a single mountain but different microhabitats (limestone vs. dolomite). Key differences: Allopatric requires a physical barrier (river, mountain); sympatric requires strong disruptive selection or chromosomal mutation." biologija 4 profil klett radna biljeznica rjesenja hot
