Actually, it can occur relatively "overnight." It happened with *Varroa
destructor*, which was unable to successfully parasitize *Apis
mellifera* despite
being in their hives for some 70 years. As Dr Denis Anderson found, it
appears that the entire varroa invasion of *Apis mellifera* can be traced
back to a mutation in a single female mite. This indeed occurred
"overnight."

Some of us can imagine it. See above.

I'm sorry for being unclear. Such "preadaptation" does not mean that the
host was previously exposed to a parasite. Humans are preadapted to
resistance to aquatic skin parasites since we tend to live out of water.
