A Quote by Francois Jacob

It is natural selection that gives direction to changes, orients chance, and slowly, progressively produces more complex structures, new organs, and new species. Novelties come from previously unseen association of old material. To create is to recombine.

The essence of Darwinism lies in its claim that natural selection creates the fit. Variation is ubiquitous and random in direction. It supplies raw material only. Natural selection directs the course of evolutionary change.

Stephen Jay Gould

People will say, "You're never going to convince me that something as complicated as an eye could come about by sheer chance." And the answer is that natural selection is the very opposite of sheer chance. Natural selection is a non-random process.

Richard Dawkins

Anytime new insight replaces an old assumption or a fossilized perception is the spring. New understandings sprout, new tolerances appear, and new curiosity draws you to previously dark places. Just as the sun shines earlier and longer in the spring, changes that seemed impossible appear to be possible with each new insight into your own health.

Gary Zukav

We actually do generate some new cells, some new neurons. So in the case of trauma there is the potential for there to be some new neural development which gives the person the chance to create new circuitry.

Jill Bolte Taylor

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

When a parasite moves to a new habitat, it can find new hosts through a process called the trans-species jump. Often, the new host has no resistance; it and the parasite haven't had time to adjust to each other through natural selection (it is frequently not in the best interest of a parasite to kill its host quickly).

Richard Preston

Each new tool we create ends an old relationship with the world and starts a new one. And we're changed by that relationship, inevitably. It changes the way we live, changes our patterns, changes our social organization.

Ellen Ullman

Still, we view that old material very much like we view the new material so if this gives us a chance to go out and promote it then, yes we will go out and do that.

Geoff Downes

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 eveloution owes its generally progressive cource, its successive conquests, and the impresssion it gives of a smooth and steady unfolding.

Jacques Monod

Since natural selection requires a function to select, an irreducibly complex biological system, if there is such a thing, would have to arise as an integrated unit for natural selection to have anything to act on.

Michael Behe

Natural selection may lead to benefits for species, but these `higher' advantages can only arise as sequelae, or side consequences, of natural selection's causal mechanism: differential reproductive success of individuals.

Stephen Jay Gould

For a sculptor, a painter, a weaver, a potter, the dialogue between one's materials and what one makes from them is easy to see: discover a new material or a new way to use a familiar one, and new things can be made, sometimes leading to the discovery of more new material, leading to more creation.

Andrea Barrett

Peace is a daily, a weekly, a monthly process, gradually changing opinions, slowly eroding old barriers, quietly building new structures.

John F. Kennedy

If a person is constantly evolving, constantly reading new material and being exposed to new material and growing in life, then you're becoming, hopefully, a more intelligent and well-rounded individual. If you're not then something's wrong and you're sliding back in the other direction.

Clint Eastwood

Although I insist that God has always had the power to intervene directly in nature to create new forms, I am willing to be per-suaded that He chose not to do so and instead employed secondary natural causes like random mutation and natural selection.

Phillip E. Johnson

The theory of natural selection is the centerpiece of The Origin of Species and of evolutionary theory. It is this theory that accounts for the adaptations of organisms, those innumerable features that so wonderfully equip them for survival and reproduction; it is this theory that accounts for the divergence of species from common ancestors and thus for the endless diversity of life. Natural selection is a simple concept, but it is perhaps the most important idea in biology.
