ERV FAQ: What's all this about the Phoenix Virus? Sounds like a Michael Crichton science fiction story!
A bunch of mad scientists looked at a set of very similar ERVs that lurk in our genomes, and figured that maybe, they all derived from the same retrovirus, a retrovirus that either endogenized (entered the germ-line) independently on separate occasions, or endogenized once and repeatedly integrated in different locations via transposition. Because they thought that each ERV might derive from the same original retrovirus, but was wonky because reverse transcription is so error-prone, they figured that the ERVs were likely to have different
The reckless fools.
This page explains the experiment in more detail and links to their peer-reviewed report.
This not science fiction.
