Well, there is your problem. You like the Darwininians consider anything, I repeat anything, outside of the Darwinian conception as non-science. Read Dr. James Shapiro, and/or you might actually read some of the links that Gore3000 has provided. Such as this one
The discovery that human-specific retroviruses emerged at the same time other researchers believe humans and chimps diverged was startling. Equally interesting, however was the discovery that the oldest subfamily of HERV elements is closely related and gave rise to the youngest and most recently active group of these elements. This suggests, the authors say, that "ancient families of HERVs may be capable of retaining the potential for biological activity over long spans of evolutionary time."
Interest in retroelements, which McDonald has been studying for more than a decade, has been growing recently. In a paper published last December in Nature Genetics, two researchers from Tufts University, Jennifer Hughes and John Coffin, identified 23 new members of the HERV-K group the assemblage thought to contain the most recently active members. They found that at least 16 percent of those elements had undergone rearrangements that resulted in large-scale "deletions, duplications, and chromosome reshuffling during the evolution of the human genome."
The widespread presence of these viral elements led Coffin to tell one science magazine that humans probably have "more viruses in our genes than genes in our genes."
Just how these retroviral elements have moved around in the human genome and possibly changed organisms at the morphological level remains speculative. But there is increasing evidence that they may have been and may still be a driving force between evolution at the cellular and organismal levels.
I don't see anything non-Darwinian here.
I've read some of gore3000's links, but I don't see anything non-Darwinian there amidst some of the other stuff either. RNA and DNA viruses, prions and other DNA transfer mechanisms have been recognized as having a role in mutations for several years. That's why we built manufacturing processes utilizing them.
