Ascientist wrote a paper titled “directional selection in action” after observing a population of mice for 15 years. the mice typically preferred to eat berries, although a few would also eat insects. after a drought in year 3, the scientist observed that more mice were eating insects. by year 10, most of the mice in the population ate insects in addition to berries. which best describes her article?

This paper of Directional Selection in Action pronounces it research in relation to how living organisms can adapt to certain environmental changes which forces them to change their behavior in order to survive. For instance, as provided  that rats have changed their source of energy from insects to berries, from berries to insects, and eating them both have shown benefits for these organisms to survive.
