Mutations:

• Happen when a species needs them.

• Happen when the environment changes.

• Happen randomly, all the time.

• Happen to individual organisms that need them.

Match the following

• Mutation

• Errors in copying DNA during cell division or damage repair.

• Creates different alleles. Mutation.

• Scientific theory

• Science's highest level of certainty

• The individuals with variations that help them in the current environment are more likely to survive long enough to pass on their genes.

• Survival of the Fittest

• The name of changes that create different alleles.
