Amplify Evolution

The body structures for a population of green herons (a species of bird that lives near water) were stable for a long time. Then, their body structures changed to make the green herons taller. Why did this happen?

• It is impossible to say without more information.

• The green heron population wanted to be taller

• Their environment must have changed

• Organisms naturally become taller over time.

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.
