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?

This explanation is most credible because the evidence suggests that the only major genetic difference between the birds is their size, and the larger birds are less likely to be killed by predators. This aligns with the idea that larger birds may have physical characteristics that make them more difficult for predators to successfully attack, such as stronger defenses or greater agility.
