Influenza jumps species -- that's how we've gotten some of the horrible flu strains in the past.

How does it happen? Virus mutates in such a way that it becomes infective to the new species it attacks. It's part of their way of surviving. They do it by altering their genetic code. Or, someone like Iraq's Dr. Germ does it for them.

NOTE: I'm not saying this is a bioterror weapon.
