View Full Version : II-Mechanisms of Speciation


  1. 4- In allopatric speciation, geographic isolation leads to speciation
  2. 5- Reproductive barriers can evolve as populations diverge
  3. 6- Sympatric speciation takes place without geographic isolation
  4. 7- Sexual selection can lead to speciation
  5. 8- Isolated islands are often showcases of speciation
  6. 9- Evolution Connection: Long-Term field studies document evolution in darwin’s finches
  7. 10- Hybrid zones provide opportunities to study reproductive isolation
  8. 11- Speciation can occur rapidly or slowly
