[初賽第一階段] 進化（1） [Preliminary Phase 1] Evolution (1)

Big Concept: Evolution Topic: Speciation Bloom's Taxonomy: understand Learning Goal: 1. Define speciation. 2. Describe types of reproductive isolation (prezygotic vs postzygotic). 3. Explain allopatric speciation with simple examples. 4. Understand that reduced gene flow leads to divergence. Key Learning Points: 1. Definition of speciation 2. Reproductive isolation (prezygotic/postzygotic barriers) 3. Allopatric speciation (geographic isolation) 4. Basic idea of gene flow and divergence Note: Understand: Understanding that reproductive isolation is a key driver of speciation.
