1  The change in genetic make up of a population over many generations.  Caused by:  Natural selection (best adapted survive)  Inbreeding  Mutation  Hybridization

2 What is speciation?

3  A new species forms when a group of organisms it separated from the rest for a long time.  A new species is made that cannot breed with the original species  Caused by  Climate change  Mutation  Geography

4 Natural Selection Brain POPNatural Selection Brain POP/

5  When a species adapts to its environment to improve their chances of survival.  Adaptations are passed on to offspring  AKA: Natural Selection Adaptation Examples Whale Hunting Adaptation Video
