“Retroviruses make up about 8 percent of the human genome. When these viruses insert into the genome, the result is usually bad for the host. But not always: Some retrovirus proteins can help fight off infection with other retroviruses. And at least twice in primate evolution retrovirus insertions have added genes to the host genome that aid in making the placenta.”

May I recommend this book? Darwin's Radio (http://www.gregbear.com/books/darwinsradio.cfm). Hard sci-fi. You might like it, considering your LibraryThing profile. It sent me spinning into speculation land for weeks.
Thanks for the recommendation, I'll keep it in mind. Sadly lately I haven't been reading much.
