" I am sure you can always find the reason for extinction. That is survival of the fittest."

Tautology.

"Survival of the fittest" simply means survival of the survivors. Without being able to point out what condition, feature, or fortuitous chain of events made them survivors, it has no meaning beyound observation of the temporarily obvious.
