Biology lab changes in a population
How can changes in a population lead to new species?
Questions:
1. We have documented many examples of this type of speciation occurring. Darwin’s finches are the most famous example. View the model shown. Discuss what kind of geographic barriers would have led to the finch speciation in the Galapagos.
2. What data would you need to gather from the flies to determine if evolution (or speciation) was occurring in the groups?
3. Synthesis: How does reproductive isolation differ in sympatric modes and allopatric modes of
speciation?
