Evolution Quotes

“As a consequence, geneticists described evolution simply as a change in gene frequencies in populations, totally ignoring the fact that evolution consists of the two simultaneous but quite separate phenomena of adaptation and diversification.”

“We live between two worlds; we soar in the atmosphere; we creep upon the soil; we have the aspirations of creators and the propensities of quadrupeds. There can be but one explanation of this fact. We are passing from the animal into a higher form, and the drama of this planet is in its second act.”

“A living organism must be studied from two distinct aspects. One of these is the causal-analytic aspect which is so fruitfully applicable to ontogeny. The other is the historical descriptive aspect which is unravelling lines of phylogeny with ever-increasing precision. Each of these aspects may make suggestions concerning the possible significance of events seen under the other, but does not explain or translate them into simpler terms.”

“Nothing can better express the feelings of the scientist towards the great unity of the laws of nature than in Immanuel Kant's words: "Two things fill the mind with ever new and increasing awe: the stars above me and the moral law within me."... Would he, who did not yet know of the evolution of the world of organisms, be shocked that we consider the moral law within us not as something given, a priori, but as something which has arisen by natural evolution, just like the laws of the heavens?”

“Life's Solution builds a forceful case for the predictability of evolutionary outcomes, not in terms of genetic details but rather their broad phenotypic manifestations. The case rests on a remarkable compilation of examples of convergent evolution, in which two or more lineages have independently evolved similar structures and functions.”

“Reincarnation, at least as I conceive it, does not nullify what we know about evolution and genetics. It suggests, however, that there may be two streams of evolution -- the biological one and a personal one -- and that during terrestrial lives these streams may interact.”

“was revolution much more than one fast kick forward in the long process called evolution? We condemened the 'cost' of revolution; but was it higher than the cost over centuries in backward, underdeveloped communities, which still covered two-thirds of the earth and which still could not guarantee their populations daily bread?”

“For nearly two centuries, scholars and politicians have debated the future of capitalism. Its critics, most prominent among them Karl Marx, have seen capitalism as intrinsically unstable, full of contradictions that will lead eventually to its collapse. Its supporters see it as the best way to allocate resources and rewards. Some even hint that the democratic capitalistic society is not just a phase in the historical evolution of economic systems but its ultimate end.”

“A spiritual partnership is a partnership between equals for the purpose of spiritual growth. Nothing like this archetype has existed before because nothing like this was required before in the human experience. And spiritual partnerships can be created in a biological family, they can be created among friends, they can be created in the workplace, they can be created anywhere that two or more individuals are committed to their own spiritual evolution and are striving to relate to each other as equals.”

“Each of us is the next step in evolution along the lineage created by our two parents. Our higher purpose on earth can be found by recognizing what our parents accomplished and where they left off. By reconciling what they gave us with what they left us to resolve, we can get a clear picture of who we are and what we are meant to do.”

“If we want to sum up the theory of evolution by natural selection in two words, which have great relevance for all societies and businesses, we should simply remember: diversity works.”

“Social evolution is a resultant of the interaction of two wholly distinct factors: the individual ... bearing all the power of initiative and origination in his hands; and, second, the social environment with its power of adopting or rejecting both him and his gifts. Both factors are essential to change. The community stagnates without the impulse of the individual. The impulse dies away without the sympathy of the community.”

“But the 20th century suffered "two" ideologies that led to genocides. The other one, Marxism, had no use for race, didn't believe in genes and denied that human nature was a meaningful concept. Clearly, it's not an emphasis on genes or evolution that is dangerous. It's the desire to remake humanity by coercive means (eugenics or social engineering) and the belief that humanity advances through a struggle in which superior groups (race or classes) triumph over inferior ones.”

“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.”

“Then, of course, through the umbilical link we all tumble backwards down the spiralling DNA staircase to one common ancestor in Africa, and before that some bunch of curious monkeys. Down and down we go unto the sea, unto the dust, the single cellular dust. What impulse drove one cell to become two? What yearning pulled the fish on to the land? What caused apes to walk upright? Some invisible magnetic pull. Is there a difference between attraction and intention? Where is evolution taking us?”

“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.”

“Two hundred years ago, we were all busy farming and we all had a role to play. The home was a unit of production. We made food and all the things we needed, we took care of our kids and were connected to purpose in our evolution. When the Industrial Revolution came along, it took away a lot of the work the men had done.”

“If evolution really works, how come mothers only have two hands?”

“There are two basic motivating forces: fear and love. When we are afraid, we pull back from life. When we are in love, we open to all that life has to offer with passion, excitement, and acceptance. We need to learn to love ourselves first, in all our glory and our imperfections. If we cannot love ourselves, we cannot fully open to our ability to love others or our potential to create. Evolution and all hopes for a better world rest in the fearlessness and open-hearted vision of people who embrace life.”

“There are some dogs which, when you meet them, remind you that, despite thousands of years of man-made evolution, every dog is still only two meals away from being a wolf. These dogs advance deliberately, purposefully, the wilderness made flesh, their teeth yellow, their breath a-stink, while in the distance their owners witter, "He's an old soppy really, just poke him if he's a nuisance," and in the green of their eyes the red campfires of the Pleistocene gleam and flicker.”

“On some dimension or other, every event in life can be causing only one of two things: either it is good for you, or it is bringing up what you need to look at in order to create good for you. Evolution is win-win…life is self-correcting.”

“In their recently aborted struggle to inject Genesis literalism into science classrooms, fundamentalist groups followed their usual opportunistic strategy of arguing two contradictory sides of a question when a supposed rhetorical advantage could be extracted from each.”

“And no one has the right to say that no water-babies exist, till they have seen no water-babies existing; which is quite a different thing, mind, from not seeing water-babies; and a thing which nobody ever did, or perhaps will ever do. But surely ... they would have put it into spirits, or into the Illustrated News, or perhaps cut it into two halves, poor dear little thing, and sent one to Professor Owen, and one to Professor Huxley, to see what they would each say about it.”

“In the animal world, on the other hand, the process of evolution is characterised by the progressive discrimination of the animal and vegetative functions, and a consequent differentiation of these two great provinces into their separate departments.”

“The distinguishing of the strata, or layers, in the embryonic membrane was a turning-point in the study of the history of evolution, and placed later researches in their proper light. A division of the (disc-shaped) embryo into an animal and a plastic part first takes place. In the lower part (the plastic or vegetative layer) are a serous and a vascular layer, each of peculiar organization. In the upper part also (the animal or serous germ-layer) two layers are clearly distinguishable, a flesh-layer and a skin-layer. (1828)”

“There is little chance that aliens from two societies anywhere in the Galaxy will be culturally close enough to really 'get along.' This is something to ponder as you watch the famous cantina scene in Star Wars. ... Does this make sense, given the overwhelmingly likely situation that galactic civilizations differ in their level of evolutionary development by thousands or millions of years? Would you share drinks with a trilobite, an ourang-outang, or a saber-toothed tiger? Or would you just arrange to have a few specimens stuffed and carted off to the local museum?”
