IF DARWIN'S THEORY of evolution were true, there would be in every species a constant and ruthless competition to survive: a competition in which only a few in any generation can be winners. But it is perfectly obvious that human life is not like that, however it may be with other species.
It is good for the survival of mankind both for individual men to cooperate together, and for groups of men to live in the presence of other species that help provide such things as food, fur, etc. Therefore, Darwinism would favor the survival of men who cooperate and conserve other species. Those are the kinds of men that would tend to survive and reproduce. Therefore, the article begins with a complete and utter fallacy as its opening point. It's not worth reading further.
Oh? So why aren't we all tree-hugging communists?
