The fossil record provides evidence that evolution has occurred in part because:
It shows that organisms have not changed over time.
It shows that the bodies of groups of organisms have changed over time.
It shows that the bodies of groups of organisms have changed over time.
Comparing the amino acid sequencing in different organisms shows that:
There are less difference in species more closely related
There are more difference in species more closely related
There are less difference in species more closely related
