Lesson 8: Speciation and Isolation Mechanisms
Duration of Days: 2
Lesson Objective
Describe the conditions that lead to allopatric and sympatric speciation.
Classify reproductive isolating mechanisms as either pre-zygotic or post-zygotic barriers.
At what point do two populations diverge enough to be considered separate species?
What biological barriers prevent different species from successfully interbreeding?
