Identifying genes like HMGA2 is important, because it is evidence of natural selection. How does it demonstrate that natural selection occurred in Darwin's finches? (1 point)

Question

Scientists study similar genes that also impact the same traits to see how they work together and influence one another.
Scientists observe the frequency of the different forms of the gene and how it changes in response to the environment.
Scientists mutate and modify the gene in the lab to see how changes might occur to the organism.
Scientists identify different forms of the gene in individuals from the same species and observe how it shows up as a trait.

Answer 1

The correct answer is:

Scientists observe the frequency of the different forms of the gene and how it changes in response to the environment.

This demonstrates natural selection because it shows how variations in the gene frequency correlate with changes in environmental pressures, leading to adaptations that enhance survival and reproduction in specific niches occupied by Darwin's finches.
