How about a simple virus mutation? Something as deadly as Ebola
and as contagious as the common cold might spread so fast that
scientists would have no time to study it. Compared with other
mammals there is remarkably little genetic variation in the Human
Race so it is at least conceivable that one very bad bug could
cause an extinction, sort of like a Dutch Elm Disease for people.
I'm not expecting it to happen but it's something to think about.
