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)
Responses
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.

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.

The correct response is:
Scientists observe the frequency of the different forms of the gene and how it changes in response to the environment.
This answer demonstrates how natural selection can occur in Darwin's finches by showing that variations in the HMGA2 gene can affect traits that influence survival and reproduction, leading to changes in gene frequency over generations in response to environmental pressures.
