Bacteria Can Take Up DNA from the Environment, Providing a Way

Bacteria can take up DNA from the environment, providing a way for bacteria to increase genetic variation and acquire new genes and DNA sequences. Similarly, bdelloid rotifers can incorporate DNA from the environment into their genomes. The similar means of achieving genetic diversity in these two groups of organisms is a good example of:

A) coevolution.
B) convergent evolution.
C) homology.
D) analogy.
E) horizontal gene transfer.
