Question

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 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. This demonstrates natural selection in Darwin's finches because the gene HMGA2 affects beak size and shape, which are important traits for survival and reproduction in different environments. By studying changes in the frequency of this gene in response to environmental factors, scientists can see how natural selection has acted on the population of finches over time.
