The study by the Grants in the Galapagos showed that finches with larger beaks could survive lower rainfall because their larger beaks allowed them to secure more food when compared to finches with smaller beaks. This shows how __________.
A. natural selection acts on variation within a species
B. spontaneous mutation causes evolution
C. gene flow allows for the survival of the species
D. inbreeding cannot occur between individuals with different acquired characteristics
