Natural selection Quotes

“I am drawn to a fourth alternative, natural teleology, or teleological bias, as an account of the existence of the biological possibilities on which natural selection can operate. I believe that teleology is a naturalistic alternative that is distinct from all three of the other candidate explanations: chance, creationism, and directionless physical law. To avoid the mistake that White finds in the hypothesis of nonintentional bias, teleology would have to be restrictive in what it makes likely, but without depending on intentions or motives. This would probably have to involve some conception of an increase in value through the expanded possibilities provided by the higher forms of organization toward which nature tends: not just any outcome could qualify as a telos. That would make value an explanatory end, but not one that is realized through the purposes or intentions of an agent. Teleology means that in addition to physical law of the familiar kind, there are other laws of nature that are "biased toward the marvelous".”

“Our present intricate humanly consciousness evolved after a long journey of struggle. And the beauty of natural selection is that our struggle against nature made us worthy of being rewarded with the 3 lbs. lump of highly advanced biological computer by our Mother Nature herself.”

“We are a biological species arising from Earth’s biosphere as one adapted species among many; and however splendid our languages and cultures, however rich and subtle our minds, however vast our creative powers, the mental process is the product of a brain shaped by the hammer of natural selection upon the anvil of nature.”

“Nature is a strong brand name. Everybody knew that. First thing, Nomenclature 101. Slap Natural on the package, you were golden. Those words on the package promise ease from metropolitan care, modern worries. And out here, if you opened things up, underneath the cellophane, what did you find inside? That fruit has splendid packaging, it has solid consumer awareness and is an animal favorite. Its seeds will be deposited in spoor miles away and its market dominance will increase. Splendid and beautiful petals are great advertising--the insects buzz and hop from all points every weekend to hit this flower-bed mall. Natural selection was market forces. In business, in the woods: what is necessary to the world will last.”

“It is therefore scientifically correct to say that 'natural selection has been proved to be an agent of evolutionary change' - we can, in fact, prove it by doing. But it is totally illegitimate to claim that the discovery of this mechanism - natural selection - proves that the cause of evolution 'was automatic with no room for divine guidance or design'.”

“Even today a good many distinguished minds seem unable to accept or even to understand that from a source of noise natural selection alone and unaided could have drawn all the music of the biosphere. In effect natural selection operates upon the products of chance and can feed nowhere else; but it operates in a domain of very demanding conditions, and from this domain chance is barred. It is not to chance but to these conditions that evolution owes its generally progressive course, its successive conquests, and the impression it gives of a smooth and steady unfolding.”

“I have called this principle by which each slight variation if useful is preserved by the term natural selection.”

“To suppose that the eye with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I confess, absurd in the highest degree...The difficulty of believing that a perfect and complex eye could be formed by natural selection , though insuperable by our imagination, should not be considered subversive of the theory.”

“Natural selection is a blind and undirected consequence of the interaction between variation and the environment. Natural selection exists only in the continuous present of the natural world: it has no memory of its previous actions, no plans for the future, or underlying purpose.”

“The very comprehensibility of the world points to an intelligence behind the world. Indeed, science would be impossible if our intelligence were not adapted to the intelligibility of the world. The match between our intelligence and the intelligibility of the world is no accident. Nor can it properly be attributed to natural selection, which places a premium on survival and reproduction and has no stake in truth or conscious thought. Indeed, meat-puppet robots are just fine as the output of a Darwinian evolutionary process.”
