Survival might relate to accidental events. A species might accidentally
survive regardless of its possible maladaptative state. The addition of
the word `fittest', makes sure that survival applies only to the most
vigorous and best equiped, best adapted and most successful species. Even
if it's tautological, that still doesn't diminish its significance of the
success in explaining nature. Let's not waste our energy on petty syntactic
matters, shall we. I say we stay focused on the more important issues
of semantics instead!
Why there's a myriad of different species and not one dominant?
Suppose there's only one, to be antropocentric let's say the human species.
We run into obvious trouble at feeding time: Where do we obtain our food?
We necessarily have to resort to cannibalism then.
The point is this: There's enough space on earth, enough resources and
plenty of positions on the food-chain for a multitude of different species
to thrive. Nature seizes on such possibilities through mutability of species
via natural selection. Then there's symbiotic relationships. Often,
one species cannot live without the existence of the other. To take it to
the extreme, there are ample examples (bacteria, shit-flies) around of
species living off of other species' feces!

I know... If this interpretation is still entertained by the masses,
popularizing evolution has still a long way to go. A sorry state of affairs
then, but this can be overcome.
Anyway, I don't know about you guys in the UK and US, but the weather here
in Holland is too good to stay inside. I'll be working on my tan as of
now (while reading about evolution, of course!).
Au revoir and cheers!
