This statement is a tautology.

Love this quote.

Inaccurate and plain wrong. The theory of survival of the fittest is believed by those holding to the theory of evolution as an adequate explanation of human behavior. Therefore they posit: why should they sacrifice any means or comfort for their adversary? Supposedly there were other subspecies from the genus homo (which is of course a silly joke) but ask the author how good these supposedly extinct relatives of homo sapiens think we are.
