Why is it appropriate to define evolution as the change in allele frequencies of a population over time?
If all the blue dots represent FST values between one species in the Americas and one species in Oceania, does this pattern of genetic similarity on the graph suggest that Native Americans and the people of Oceania followed very different migration routes? Why or why not?
How can a shift in the proportion of genes in a population could lead to the evolution of a new species?
Explain why evolution happens to a whole population rather than to a single individual.
