Actually species of parasites are extremely host specific. That would
indicate that species have been co-evolving together for millions of
years. They have been able to calculate back using some DNA test to
when the crab louse became Pthirus pubis and exclusively began living
not only on humans, but in their one particular niche on the human
body. Parasites don't just kill off species.
Why would a parasite waste all of the time to become host specific if
the goal was to kill off the host? Things on this earth want to keep on
living. If they didn't they wouldn't be here now. There are parasites
with complex multi-species jumping aspects of their many life cycles
that require several different species to encounter different forms in a
specific sequence. I would love to know how many millions of years
something like that took to come into existence and be sustainable? And
we think that bees and varroa are going to just magically co-evolve in
30 years?
I don't believe there are any animals that live on this planet that
don't suffer from at least some form of parasite. Through it all some
survive and some don't and the earth has an amazing variety of fauna all
with parasites.
How did humans survive before we had drugs and sewage treatment plants?
WITH PARASITES. And we did it for millions of years. This may not be
quick-fix-able. In some far future time there will be some subspecies
of Varroa destructor that ONLY affects Apis mellifera. I had better be
considered in the naming since I called it.
