has an article
, reprinted from the NY Times, about the avian flu outbreak in Nigeria. One of things they mention is that while about half the people who have contacted said flu from direct contact with infected birds have died, it has not yet been transmitted from person to person. But "scientists worry that it could acquire that ability through naturally occurring biological processes"
which could set off a pandemic and kill lots of people.
They just couldn't say "scientists worry that it could evolve to acquire that ability." We wouldn't want to use the e-word. It might upset those readers who have an imaginary friend that doesn't like that word.
