This is exactly the case, according to many biologists I've been reading for
my
graduate course in Symbiosis. DNA transfer between viruses, bacteria, and
hosts (both plant and animal) IS common and routine in nature. Just like any
other genetic change or mutation, most don't work and aren't seen, but many
work even better and persist. I wish I had time to provide references here
but I need to pass the test right now. If anyone is interested in more
reading on this, let me know by private email and I'll provide details after
March 1st.
