DNA sequences from any living organism could be inserted into a bacterium, and the bacterium would be able to use the sequences to make the same proteins that the original organism did. In what way does this provide evidence for evolution?

A. Since bacteria are able to use DNA from other organisms, they must have evolved from them as a common descendant.

B. Bacteria must be less evolved than higher organisms since they can still make proteins from the DNA of other organisms.

C. Since the genetic code is the same across species, these species must have inherited it from a common ancestor.

D. Since foreign DNA was added to the bacteria, it evolved beyond higher organisms.
