Evolution Quotes - page 18
Although random mutations influenced the course of evolution, their influence was mainly by loss, alteration, and refinement... Never, however, did that one mutation make a wing, a fruit, a woody stem, or a claw appear. Mutations, in summary, tend to induce sickness, death, or deficiencies. No evidence in the vast literature of heredity changes shows unambiguous evidence that random mutation itself, even with geographical isolation of populations, leads to speciation.
Lynn Margulis
I work in evolutionary biology, but with cells and microorganisms. Richard Dawkins, John Maynard Smith, George Williams, Richard Lewontin, Niles Eldredge, and Stephen Jay Gould all come out of the zoological tradition, which suggests to me that, in the words of our colleague Simon Robson, they deal with a data set some three billion years out of date. Eldredge and Gould and their many colleagues tend to codify an incredible ignorance of where the real action is in evolution, as they limit the domain of interest to animals... very tardy on the evolutionary scene, and they give us little real insight into the major sources of evolution's creativity. By "codifying ignorance" I refer in part to the fact that they miss four of the five kingdoms of life... bacteria, protoctista, fungi, and plants.
Lynn Margulis
The oxygen crisis that began only two billion years ago prompted the evolution of respiring bacteria. These microbes that used oxygen to derive biochemical energy more efficiently than ever before eventually took over most of the world. Some of the oxygen-breathing bacteria became symbiotic, merging with different (oxygen-eschewing) bacteria to form nucleated cells, which, after becoming sexual, evolved into fungi, plants, and animals.
Lynn Margulis
In the long run, the most vicious predators, like most dread disease-causing microbes, bring about their own ruin by killing their victims. Restrained predation-the attack that doesn't kill or does kill only slowly-is a recurring theme in evolution. The predatory precursors of mitochondria invaded and exploited their hosts, but the prey resisted. Forced to be content with an expendable part of the prey (its waste)... some mitochondria precursors grew but never killed their providers. ...The original prey was probably a larger bacterium like Thermoplasma.
Lynn Margulis
Zoe slowed but didn't stop. She kept her hands in front of her, still a judicious distance from the animal.
But close enough to smell it. Close enough to see the steam rising from its warm underbelly into the night air. Four billion years of un-Earthly evolution had shaped this aggregate of cells, this beast. She looked at it. And, amazingly, it looked at her. An impossible distance from the planet of her birth, this miracle had happened: Clay had made life. Life regarded life. First light, Zoe thought.
Robert Charles Wilson
Man emerged as the dominant type on earth about a million years ago, but has only been really effective as a psychosocial organism for under ten thousand years. In that mere second of cosmic time, he has produced astonishing achievements - but has also been guilty of unprecedented horrors and follies. And looked at in the long perspective of evolution he is singularly imperfect, still incapable of carrying out his planetary responsibilities in a satisfactory manner...
Julian Huxley
Between 1937 and 1941, Dobzhansky went from being able to allow for the possibility of evolutionary mechanisms other than those he favored to a position in which everything that did not fit his definition of evolution was rejected.
In the midst of his outpouring of anger at and dismissal of Goldschmidt, Dobzhansky neglected to consider the fact that while Goldschmidt's systemic mutations may not have been observed, neither had the mechanisms of speculation that he, or anyone else, for that matter, had proposed. ...it was and still is the case that, with the exception of Dobzhansky's claim about a new species of fruit fly, the formation of a new species, by any mechanism, has never been observed.
Theodosius Dobzhansky
...what would be most extraordinary is this, that anybody who considered the state of the Liberal party then [1896] and now should expect me voluntarily to return to the Liberal party. (Laughter.) I left the Liberal party because I found it impossible to lead it, in the main owing to the divisions to which I referred in my letter. (Hear, hear.) The Liberal party in that respect is no better now, but rather worse; and it would indeed be an extraordinary evolution of mind if, after having left the Liberal party on that ground, I were to announce my intention of voluntarily returning to it in its present condition. No, gentlemen, so far as I am concerned, I must repeat what I have said on that subject in all my speeches, that for the present, at any rate, I must proceed alone. I must plough my furrow alone.
Archibald Primrose, 5th Earl of Rosebery
The evolution of earth-cult to sky-cult shifts woman into the nether realm. Her mysterious procreative powers and the resemblance of her rounded breasts, belly, and hips to earth's contours put her at the center of early symbolism. She was the model for the Great Mother figures who crowded the birth of religion worldwide. But the mother cults did not mean freedom for women. On the contrary [...] cult objects are prisoners of their own symbolic inflation. Every totem lives in taboo.
Camille Paglia
I do not care if people agree or disagree with my particular brand of knowledge or formulation of truth (for we all must have that for ourselves) but they are impossible to help if completely satisfied with their own. To me, the ultimate hell (if there is a hell, which I very much doubt) would be a state of complete satisfaction with one's own viewpoint and therefore such a static condition that all evolution in thought and all progress would be permanently arrested.
Alice Bailey
Evolution is the fundamental idea in all of life science, in all of biology. It's like, it's very much analogous to trying to do geology without believing in tectonic plates. You're just not gonna get the right answer. Your whole world is just gonna be - a mystery. Instead of an exciting place.
Bill Nye
As a graduate student at Yale, I studied the whole of Christian theology but focused my attention on the Darwinian controversies. I wanted to get to the root of the conflict between Darwinian evolution and Christian doctrine. In the course of my research I learned (to my surprise) that biblical chronology played almost no role in the 19th- century controversies, since most theologians had already accepted geological evidence for the age of the earth and re-interpreted the days in Genesis as long periods of time. Instead, the central issue was design. God created the cosmos with a plan in mind. This affirmation is among the most basic in all of Christianity (and other theistic religions as well, including Unificationism). And that plan included human beings as the final outcome of the creative process: we are created in the image of God.
Jonathan Wells
I would like evolution to join the roster of other discredited religions, like the Cargo Cult of the South Pacific. Practitioners of Cargo Cult believed that manufactured products were created by ancestral spirits, and if they imitated what they had seen the white man do, they could cause airplanes to appear out of the sky, bringing valuable cargo like radios and TVs. So they constructed "airport towers” out of bamboo and "headphones” out of coconuts and waited for the airplanes to come with the cargo. It may sound silly, but in defense of the Cargo Cult, they did not wait as long for evidence supporting their theory as the Darwinists have waited for evidence supporting theirs.
Ann Coulter
