Somebody's crabby this morning.
Your statement:
That's how "The discovery that human-specific retroviruses emerged at the same time other researchers believe humans and chimps diverged was startling" came about. As noted for this happen all of a sudden, all of them working together, is unexplainable by evolution.
The rest of the paragraph from the article:
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."
I leave it to the discerning reader to determine where the reading comprehension problem lies.
(Maybe this can be a training question for people scoring the new SAT's.)
The news was not that they had discovered retroviruses. The news was that they discovered totally new retroviruses. There are many retroviruses so they had to check to see if these were new by comparing them to the ones in chimps. If they had just been slightly changed it would not be news. That's why the headline the article claims 'startling news'. As I said, regardless of whether evolutionists think of themselves as little better than pond scum, we are unique.
