That is what I was trying to convey.

It is subtle since if you kill all of your hosts you die, too. There must
be some of that knowledge in the genome, too.


no, it is purely a matter of categorisation on our part. Diseases kill their
hosts, parasites don't necessarily. It is our labelling, not anything the
organism is doing

Viruses don't even multiply without a host.

I presume you look up your memory bank to remind yourself how to keep
alive. Do not kill every last host. If there is stress start swopping
genes faster.

what memory bank?

The `junk DNA'.

Where is there any evidence of this. I think you are
getting carried away with the classifications again. If you run out of hosts
you just find more

Jump species? You would have to do that before you killed every last
one of the previous species.
