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 identify different forms of the gene in individuals from the same species and observe how it shows up as a trait. 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 study similar genes that also impact the same traits to see how they work together and influence one another. Scientists mutate and modify the gene in the lab to see how changes might occur to the organism. Scientists mutate and modify the gene in the lab to see how changes might occur to the organism. Scientists observe the frequency of the different forms of the gene and how it changes in response to the environment.
Scientists observe the frequency of the different forms of the gene and how it changes in response to the environment. In the case of Darwin's finches, the gene HMGA2 has been identified as playing a role in beak size and shape, traits that are important for their survival and reproduction. By studying how the frequency of different forms of the gene changes in response to environmental factors such as food availability or competition, scientists can demonstrate how natural selection acts on the population of finches. This helps to support Darwin's theory of evolution by natural selection.
