Which best describes the fossil record?

• The fossil record cannot provide evidence of evolution. 
• The fossil record provides evidence of a common ancestor to many species.
• The fossil record provides evidence that disputes the theory of evolution.
• The fossil record is inaccurate because scientists are not able to date fossils.
