that's the point - _co-evolution, all species co-evolve in response to one

Gazelles get faster and smarter, cheetahs get faster and smarter, etc.  But
if predators `went for it', ie allowed the population to increase, they
would, after not too long, kill off all the gazelles even though they run
fast.
