5. Every once in a while there are changes in DNA bases – mutations Mutations can cause misreading of DNA (4) Statistical Chances of a Mutation Occurring to One Nucleotide is 1/10 9

6. Mutations cause mostly bad disorders, but every once in a while there may be a non- harmful mutation Always remember that mutations are random events!

7. A trait (caused by a mutation) that allows an organism to have a better chance of survival (5)

8. Adaptations are a result of “beneficial” mutations, these mutations cause changes in organisms and allow them to survive. All organisms have a mix of genes. Certain environments cause specific genes to be chosen from pre- existing genetic information.

9. Any animal that can not survive in the environment will go extinct. (6)
