Question

Use the sources to answer the following question. Source A Black ladybugs with red spots are referred to as melanic, and red ladybugs with black spots are referred to as nonmelanic. Because dark objects absorb more heat, the melanic ladybugs are better adapted to keep warm at lower temperatures. Paul Brakefield studied a population of ladybugs in Tilburg, the Netherlands between 1980 and 2004. As the average temperature in the area increased over a period of twenty four years, he noticed that the percentage of melanic ladybugs in the population decreased. Source B - image Source C - image Part A: How genetic variation in the ladybug population increased the survival probability of some individuals and changed the population over time. Include evidence and reasoning.
