Discussion Questions: Hummingbird Species in the Transitional Zones
Explain the hypothesis presented by the scientists profiled in this segment to explain the process of speciation in hummingbirds and possibly other species. How does this hypothesis differ from the traditional view that speciation often requires geographic separation of populations? Why were the researchers collecting blood from the populations they studied? Discuss at least two possible analyses that could be performed on those samples and, identify at least two different questions that might be answered with sufficient data.
