Retroviruses and evolution.
A wide variety of different genetic elements and DNA sequences have used reverse transcription in their replication or transposition. Some of these elements may be evolutionarily related and show a continued evolution to autonomy from the cell genome. The evolution of a cancer reflects a similar drive for autonomy from the organism.
