Question

A population of land snails colonized a field of light-colored grass. At first, the population contained two types of snails, one with brown bands on their shells and another with yellow bands on their shells. After 10 years, most of the snails have shells with yellow bands.

Which process most likely led to an increase in the number of snails with yellow bands?

Answer 1

The process that most likely led to an increase in the number of snails with yellow bands is **natural selection**. This is because the yellow-banded snails may have had an advantage in the light-colored grass environment, making them less visible to predators, and thus more likely to survive and reproduce compared to the brown-banded snails.
