I have called this principle, by which each slight variation, if useful, is preserved, by the term of Natural Selection.

I have called this principle, by which each slight variation, if useful, is preserved, by the term of Natural Selection

Nevertheless so profound is our ignorance, and so high our presumption, that we marvel when we hear of the extinction of an organic being; and as we do not see the cause, we invoke cataclysms to desolate the world, or invent laws on the duration of the forms of life!

One general law, leading to the advancement of all organic beings, namely, multiply, vary, let the strongest live and the weakest die.

Natural selection is anything but random.

Natural selection eliminates and maybe maintains, but it doesn't create.
