Bush and the flu virus: an evolving relationship

Dave Lindorff at Counterpunch makes this observation about Bush's Monday press conference:

The Creationist-in-Chief, in his latest press conference, expressed concern that the Bird Flu virus could evolve into a strain capable of being transmitted from human to human, instead of just from bird to bird or bird to human. If so, he warned, it could lead to up to 2 million deaths in the U.S. alone. Accordingly, he is proposing using the military to quarantine areas of outbreaks. His backers in the Republican-led Congress just slid $3.9 billion into the latest military funding bill to cover epidemic preparedness in case the Bird Flu evolves into a human flu.

What was that? The flu virus "evolves"?

H-m-m-m-m. I wonder what else evolves? Life on earth, perhaps?

Are we saying that viruses evolve, but not bacteria? Or that only simple organisms evolve, but not complex animals? I wonder where one draws the line?

Ah, yes. The slippery slope.
