Everything becomes elitist once taken for granted. But that does not necessarily mean it is completely false. The theory of evolution, though supported by many closed-minded individuals, was founded by very open-minded individuals. But open minds can only hold so much, so we must have more of them to further the theory and reveal more of its truth and discard more of its untruth. There is no heirarchy in evolution, only seemingly limitless variables. If something dies and is does not produce offspring, then you can look at it as being the fault of the environment, not that it is defective.
