Natural Selection is not Evolution. Yet, ever since the two words have been in common use, the theory of Natural Selection has been employed as a convenient abbreviation for the theory of Evolution by means of Natural Selection, put forward by Darwin and Wallace. This has had the unfortunate consequence that the theory of Natural Selection itself has scarcely ever, if ever, received separate consideration.

Ronald Fisher

We are moving from unconscious evolution through natural selection to conscious evolution by choice.

Barbara Marx Hubbard

Evolution by natural selection is not an idle hypothesis. The genetic variation on which selection acts is well understood in principle all the way down to the molecular level.

E. O. Wilson

Creationists argue that natural selection is only a negative process, and therefore cannot create anything. Chopra argues that skepticism is only a negative process, and therefore does not lead to knowledge. Both are wrong for the same reasons. They ignore the generation of diversity and new ideas upon which natural selection and skepticism acts. Weeding out the unfit is critical to both - natural selection allows evolution to proceed, and skepticism allows science to advance.

Steven Novella

All scientists agree that evolution has occurred-that all life comes from a common ancestry, that there has been extinction, and that new taxa, new biological groups, have arisen. The question is, is natural selection enough to explain evolution? Is it the driver of evolution?

Lynn Margulis

Group selection and individual selection are just two of the selection processes that have played important roles in evolution. There also is selection within individual organisms (intragenomic conflict), and selection among multi-species communities (an idea that now is getting attention in work on the human microbiome). All four of these levels of selection find a place in multi-level selection theory.

Elliott Sober

You know, Darwin said through natural selection things go gradually, and he was talking about pigeon's evolution or horses evolving, getting faster. But in fact if you look at evolution on a bigger scale, cosmic evolution and you look at culture evolution you see it jumps, it goes through phase changes, and that's very exciting.

Charles Jencks

You can be a thorough-going Neo-Darwinian without imagination, metaphysics, poetry, conscience, or decency. For 'Natural Selection' has no moral significance: it deals with that part of evolution which has no purpose, no intelligence, and might more appropriately be called accidental selection, or better still, Unnatural Selection, since nothing is more unnatural than an accident. If it could be proved that the whole universe had been produced by such Selection, only fools and rascals could bear to live.

George Bernard Shaw

Natural selection is not an inflammatory phrase; evolution is.

Peter Agre

In fact, nothing in science as a whole has been more firmly established by interwoven factual information, or more illuminating than the universal occurrence of biological evolution. Further, few natural processes have been more convincingly explained than evolution by the theory of natural selection, or as it has been popularly called, Darwinism.

E. O. Wilson

I am quite sure that our views on evolution would be very different had biologists studied genetics and natural selection before and not after most of them were convinced that evolution had occurred.

John B. S. Haldane

Now let me step back from the problem and very generally discuss natural selection and what we know about it. I think it is safe to say that we know for sure that natural selection, as a process, does work. There is a mountain of experimental and observational evidence, much of it predating genetics, which shows that natural selection as a biological process works.

David M. Raup

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.
