People often think of evolution as what they call survival of the fittest. However, that means a fight among members of a species. This is not what is really meant.
The 'fight' is with the environment and the species and not a fight of one individual with another.
If the species has a way of best surviving what the environment throws at it, it will survive. Other species might not and will die out.

Natural selection IS the environment!
The selection pressure on variant organisms is only the pressure from the changing and immediate environment.
Natural selection acts as a natural, non random filter. It selects the fittest.
Ignoring the mis-quote ;
when the environment changes so does the definition of the "fittest".
Individuals are naturally selected and then only the populations those individuals are in evolve.
Survival of the fittest
The theory of Evolution and Survival of the fittest.
Charles Darwin. Also known as Darwin's Theory of Evolution.
According to evolutionary theory, natural selection is the principle that directs evolution.
Be careful with this, it is usually misinterpreted as survival of fittest individuals. Instead it is survival of fittest population via death of some individuals early. Individuals never evolve, they are fixed genetic snapshots in the movie of life, they simply live or die. Populations evolve.
Poorly - what was described (and what really happens) is the death of the less fit (as well as the unlucky). "Survival of the fittest" is a political slogan.

The theory of Evolution and Survival of the fittest.
Charles Darwin. Also known as Darwin's Theory of Evolution.
Extinction is part of the Theory of Evolution. This goes along with natural selection and survival of the fittest. Organisms that go extinct do so because they are no longer able to survive in the habitat.
Because he studied organisms very closely and propounded the theory of evolution with the phrase 'Struggle for existence and survival of the fittest organisms'.
Darwin has a theory of Survival of the Fittest.
