Well, with things like alligators, crocodiles, coelacanths, frilled sharks,
white sturgeon, alligator gar, paddlefish, etc. - there must not be any
environmental pressure to induce change.  Evolution is survival of the fit -
which means there will be variation, but if that species is already optimized
for the environment that it inhabits, than any other mutation is a detriment - a
"devolution" of sorts.
