Some tribes are immune to polio, they are infected with it yet have no resistance to the common cold.
Other regions people are immune from malaria, yet thier ability to cope with that maladay also makes them vunerable to the AIDS virus.
If we do not evolve we go into extinction very quickly.
This is not an overnight process, but one of several generations.
