- 10. Multiple ChoiceHow do fossils provide evidence that evolution has happened on Earth?Fossils show how the sizes of certain animals has changed drastically over millions of yearsFossils show that some species have gone extinctFossils show how life forms present today are different than those from the pastDifferent sedimentary rock layers provide evidence for how the environment has changed over time
