Select all that are true regarding a theory? (you can choose more than one) Make sure to read all choices!

• It has been proven true.

• It is supported by the majority of the scientific community.

• It has been revised as new facts are found.

• It is supported by a large body of evidence.

Describe how a theory is different from a hypothesis.

• A theory is supported by lots of facts and evidence and a hypothesis is not.

• A hypothesis is supported by lots of and evidence and a theory is not.

The sugar glider squirrel in Australia and the flying squirrel in North America have both adapted similar traits to be successful in similar environments. Which type of evidence for evolution does this illustrate?

• Fossil evidence

• Biogeography/Geographic distribution

• Similarities in embryonic development
