By the multiplying of slight modifications in the course of thousands of generations, and by the handing down of the newly-acquired peculiarities by inheritance, a greater and greater divergence from the original standard is supposed to be effected, until what may be called a new species, or, in a greater lapse of time, a new genus, will be the result.

We must recognise the essential underlaying savagery in the animal called man, and return to older and sounder principles of national life and defense. We must realise that man's nature will remain the same so long as he remains man; that civilisation is but a slight coverlet beneath which the dominant beast sleeps lightly and ever ready to awake.
H. P. Lovecraft
The evolutionary vision is agnostic in regard to systems in the universe of greater complexity than those of which human beings have clear knowledge. It recognizes aesthetic, moral, and religious ideas and experiences as a species, in this case of mental structures or of images, which clearly interacts with other species in the world's great' ecosystem.

The poet who writes "free" verse is like Robinson Crusoe on his desert island: he must do all his cooking, laundry and darning for himself. In a few exceptional cases, this manly independence produces something original and impressive, but more often the result is squalor - dirty sheets on the unmade bed and empty bottles on the unswept floor.
W. H. Auden
A somewhat casual observer from outer space might well deduce that the course of evolution in this planet had produced a species of large four-wheeled bugs with detachable brains; peculiar animals which rested when they sent their brains away from them but performed in rather predictable manner when their brains were recalled.

There are some things which cannot be learned quickly, and time, which is all we have, must be paid heavily for their acquiring. They are the very simplest things and, because it takes a man's life to know them, the little new that each man gets from life is very costly and the only heritage he has to leave.
