According to museum collections from the early 1900s, the population of one beetle species in California’s central valley used to have individuals with different colors, including red, blue, yellow and brown. The beetles were found feeding on various native plants. 50 years after almond farming became widespread, most beetles were brown-colored and found living on the bark of almond trees. Observations indicate that birds are the primary predators of beetles. Question: How and why did the population of beetles evolve to be primarily brown in color?Sentence 1: Describe the variability that was initially present in the population. Sentence 2: State which individuals in the population had the highest fitness during the event or change (if any), and why. Sentence 3: Explain what evolutionary force acted on the population, and why and how it acted. Sentence 4: Describe how the population evolved in response. Be as specific as you can (e. g., say "increased" or "decreased", rather than just "changed".)
