Imagine a population of frogs that live in the forest. The frogs have a green coloring on top that helps them blend into the forest so they are not noticed by predators. Imagine that half of this population stayed in the forest and the other half of the population moved to the hills above the forest, which are drier, with some brown grass and brown soil. Which population of frogs is likely to have more changes after many generations?

• Descendant Species 1: The frogs in the brown hills.

• Descendant Species 2: The frogs in the green forest.

• Neither.
