Question 3 (2 points) Which of the following scenarios is an example of evolution by natural selection? (2 points)
1. A population of brown birds is nearly wiped out from a volcanic eruption. Most of the surviving birds are red, and after several

II. Lions, cheetahs, and other large predators prey on a population of antelope; the fastest antelope are most likely to escape
