Consider the following scenario:
A scientist is analyzing one bird population. There is a large amount of variation in size in the population. There are also predators that eat these birds. After collecting evidence on three types of birds (small, medium, and large), the scientist discovers that the large birds are less likely to be killed. The only major genetic difference is the size of the birds. The colors and behaviors of the large birds are the same as those of the small and medium birds.
Using reasoning skills, which is the most credible explanation for what is contributing to this higher rate of survival?

The correct answer is: more likely that some of the members will have traits that let them survive and reproduce.
If members of a population have a variety of traits, it increases the chances that at least some of them will have traits that are advantageous for survival and reproduction. This is because variation in traits allows individuals to adapt to different environments and challenges, increasing their chances of survival and reproductive success. In contrast, if there is low variation in traits within a population, there may be a reduced ability for individuals to adapt to changing conditions, making them less likely to survive and reproduce.
