I get ants every spring, no big deal. But WOW! I've never seen them

Maybe 30 years ago, Time magazine had a cover story titled, IIRC, "The

They can mutate very quickly, within a couple of generations, so they
adapt to changes in the environment that eventually kill off ostensibly
"higher" forms of life.
