Evidence of Evolution

How do fossils support evolution?

• The fossil record provides evidence that organisms have changed over time.

• Individual species disappear and reappear in the fossil record over time.

• The fossil record provides evidence that all organisms developed at the same time.

• Organisms in the fossil record are identical to living organisms.

The similarities of bone structure in the diagram provide evidence of what?

• The organisms probably use there forelimbs for the same thing.

• The organisms evolved from a common ancestor.

• The organisms have the same DNA.

• All vertebrate species have identical forelimbs.

When comparing the DNA of two different organisms, the more differences in the DNA base pairs the more-

• Closely related they are.

• Distantly related they are.

• It doesn't prove anything.

• They look alike.
