• humans change
• two species are the same
• more animals survive

This makes an organism more suited to its enviornment

• species

• lifespan

• adaptations

• mutation

Surviving and reproducing show that an organism

• Natural Selection

• is not adapting

• is forming fossils

• is not reproducing
