Evolution Quotes

“The issue, as correctly emphasized by Carl Sagan, is the probability of the evolution of high intelligence and an electronic civilization on an inhabited world. Once we have life (and almost surely it will be very different from life on Earth), what is the probability of its developing a lineage with high intelligence? On Earth, among millions of lineages of organisms and perhaps 50 billion speciation events, only one led to high intelligence; this makes me believe in its utter improbability.”

“Perhaps no order of mammals presents us with so extraordinary a series of gradations as this [step by step, from humans to apes to monkeys to lemurs] - leading us insensibly from the crown and summit of the animal creation down to creatures, from which there is but a step, as it seems, to the lowest, smallest, and least intelligent of the placental Mammalia. It is as if nature herself had forseen the arrogance of man, and with Roman severity had provided that his intellect, by its very triumphs, should call into prominence the slaves, admonishing the conqueror that he is but dust.”

“Bird taxonomy is a difficult field because of the severe anatomical constraints imposed by flight. There are only so many ways to design a bird capable, say, of catching insects in mid-air, with the result that birds of similar habitats tend to have very similar anatomies, whatever their ancestry. For example, American vultures look and behave much like Old World vultures, but biologists have come to realize that the former are related to storks, the latter to hawks, and that their resemblances result from their common lifestyle.”

“Last year, the journalist Malcolm Gladwell conducted a survey of chief executive officers of Fortune 500 companies for his book Blink. He discovered that while in the US population 14.5 per cent of all men are 6ft (1.83m) or taller, among CEOs of Fortune 500 companies the proportion is 58 per cent. And while 3.9 per cent of American adults are 6ft 2in or taller, almost a third of the CEOs were that tall.”

“Fifteen hundred years is ample time in which to lose mutual comprehension. Iceland was colonized by the Norwegians at the end of the ninth century AD. Today's Icelanders, with considerable effort, can understand people from the Scandinavian peninsula, but the Scandinavians hardly understand the Icelanders. A thousand years is the minimum time span for a language to change so much that it becomes incomprehensible.”

“Space and force pervade language. Many cognitive scientists (including me) have concluded from their research on language that a handful of concepts about places, paths, motions, agency, and causation underlie the literal or figurative meanings of tens of thousands of words and constructions, not only in English but in every other language that has been studied.”

“There are many other (besides testosterone) behaviour-eliciting hormones fundamental for humen well-being, including estrogen and progesterone in females. The fact that complex behavioural patterns can be triggered by a tiny concentration of moleculas coursing through the bloodstream, and that different animals of the same species generate different amounts of these hormones, is something worth thinking about when it's time to judge such matters as free will, individual responsibility, and law and order.”

“It is the assumption of this book that there is a typical human nature. It is the aim of this book to seek it. Just like a surgeon, a psychiatrist can make all sorts of basic assumptions when a patient lies down upon the couch. He can assume that the patient knows what it means to love, to envy, to trust, to think, to speak, to fear, to smile, to bargain, to covet, to dream, to remember, to sing, to quarrel, to lie. The 'smile' of a baboon is a threat; the smile of a man is a sign of pleasure: it is human nature, the world over.”

“As an evolutionary biologist, I have learned over the years that most people do not want to see themselves as lumbering robots programmed to ensure the survival of their genes. I don't think they will want to see themselves as digital computers either. To be told by someone with impeccable scientific credentials that they are nothing of the kind can only be pleasing.”

“I have shown that those who deplore Artificial Intelligence are also those who deplore the evolutionary accounts of human mentality: if human minds are non-miraculous products of evolution, then they are, in the requisite sense, artifacts, and all their powers must have an ultimately mechanical explanation. We are descended from macros and made of macros, and nothing we can do is beyond the power of huge assemblies of macros.”

“The usual sniggering examples of animal behaviour were brought in to explain cheating. Funny how the behaviour of shrews and gibbons is never used to explain table manners or road safety or gardening, only sex. Anyway, it was bad Darwinism. Taking the example of a monkey and applying it to yourself misses the point that animal behaviour is made for the benefit of the species, not as an excuse for the individual. Being incapable of sustaining a stable pair and supporting children is really not in the interests of our species. Neither is it really in the best interests of the philanderer.”

“Creationists reject Darwin's theory of evolution on the grounds that it is "just a theory". This is a valid criticism: evolution is indeed merely "a theory", albeit one with ten billion times more credence than the theory of creationism - although, to be fair, the theory of creationism is more than just a theory. It's also a fairy story. And children love fairy stories, which is presumably why so many creationists are keen to have their whimsical gibberish taught in schools.”

“When certain unmarried men, who had lost their capacity to sin, sat indoors, breathing bad air, and passed resolutions about what was right and what wrong, making rules for the guidance of the people, instead of trusting to the natural, happy instincts of the individual, they ushered in the Dark Ages. These are the gentlemen who blocked human evolution absolutely for a thousand years.”

“Evolution throws a wonderful light on all the struggles, eccentricities, tortuous developments of the human conscience in the past. It is the only theory of morals that does. And evolution throws just as much light on the ethical and social struggle today; and it is the only theory that does. What a strange age ours is from the religious point of view! What a hopeless age from the philosopher's point of view! Yet it is a very good age, the best that ever was. No evolutionist is a pessimist.”

“It is naïve to suppose that the acceptance of evolution theory depends upon the evidence of a number of so-called "proofs"; it depends rather upon the fact that the evolutionary theory permeates and supports every branch of biological science, much as the notion of the roundness of the earth underlies all geodesy and all cosmological theories on which the shape of the earth has a bearing. Thus antievolutionism is of the same stature as flat-earthism.”

“I think evolution should be taught as an accepted principle. I say that also as the daughter of a school teacher, a science teacher, who has instilled in me a respect for science. I think it should be taught in our schools. I won't ever deny that I see the hand of God in this beautiful creation that is earth. But - that is not a part of state policy or a local curriculum in a school district. Science should be taught in science class.”

“As Stephen Jay Gould pointed out in Time, in no other Western country is the teaching of Evolution regarded as controversial. Throughout the world, one way or another, most Christian denominations have managed to reconcile belief in God with belief in the mechanisms of natural selection. A French or German or Scandinavian politician who called for students to entertain as a reasonable deduction from existing evidence the proposition that Earth is at most 10,000 years old would be bundled off to a mental hospital.”

“Even though their arguments did not invoke religion, I think we all know what's behind these arguments. They're trying to protect religious beliefs from contradiction by science. They used to do it by prohibiting teachers from teaching evolution at all; then they wanted to teach intelligent design as an alternative theory; now they want the supposed "weaknesses" in evolution pointed out. But it's all the same program - it's all an attempt to let religious ideas determine what is taught in science courses.”

“It should soon be possible dramatically to increase the intelligence and life span of a few individuals. They and their offspring could become a master race. Evolution pays no regard to social justice. It was not fair on the Neanderthals they were replaced by modern humans.”

“This is a living planet. Look around. Mars, Venus, Jupiter. Look beyond our solar system. Where else is there a place that works, that is just right for the likes of us? It has not happened just instantly. It is vulnerable to our actions. But it's the result of four and a half billion years of evolution, of change over time. And it changes every day, all the time. It would be in our interest to try to maintain a certain level of stability that has enabled us to prosper, to not wreck the very systems that give us life.”

“Our whole evolution has reached a stage where nearly every man is either ruler or ruled; sometimes he is both. By this the attitude of dependence has been greatly strengthened, for a truly free man does not like to play the part of either the ruler or the ruled. He is, above all, concerned with making his inner values and personal powers effective in a way as to permit him to use his own judgment in all affairs and to be independent in action.”
