There are two small populations of finches on one of the Galapagos Islands, each feeding on a different size seed. A drought takes place that leaves only production of the larger of the two seed types. Researchers then observe natural selection towards birds with larger beaks and bodies. However, once the rain returned and the production of smaller seeds became more prolific, there was selection towards birds with smaller beaks and bodies. What would be the best interpretation of this observed scenario?
A) macroevolution
B) directional selection
C) bottleneck effect
