The body structures for a population of chimpanzees were stable for a long time. Then, their body structures changed, making the chimpanzees stronger. Why did this happen?

• Organisms naturally become stronger over time.

• It is impossible to say without more information.

• The chimpanzee population wanted to be stronger.

• Their environment must have changed.

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.

Why is Environment important to evolution?

• It is where animals choose to live

• It causes mutations

• It decides which traits can survive and make babies

• It makes mutations happen more often

Shared Structures always come from

• random chance

• two different species in a similar environment

• a common ancestor

• species structures are entirely unique.
