Apes: luckier-than-thou

Ahhh...evolution must be wholly true after all! According to Dec. 3 The New Yorker (Informed Reader, B4), "damaged remnants of retroviruses make up about 8% of the human genome." As if that weren't enough, "[m]any of those viral fragments are shared with chimpanzees and monkeys." Dude! Second cousin to a chimp! Well, at least we're different from apes in one respect...

A recent experiment showed that humans have developed an effective defense against an extinct retrovirus, called PtERV (pronounced "pea-terv"). Chimpanzees haven't. The experiment suggested that this lack of a defense against one retrovirus actually makes chimpanzees immune to the effects of another, HIV.

Yeah, that's evolution in action, all right. So successful that it protects us from stuff that went extinct *millions* of years ago. Go figure...the intelligent designer ain't so smart when it comes to humans, eh?

Interesting points. Unfortunately all you can hear is the crickets when it comes to publicity or even debate on it. *sigh*
