Best evolution & population Quotes | Short & Famous Sayings

“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.”

“Natural selection deals ruthlessly with any population, bird or beaver, which fails to solve the problems of its environment with all those resources, learned or unlearned, which may be at its disposal.”

“Evolutionary game theory is a way of thinking about evolution at the phenotypic level when the fitnesses of particular phenotypes depend on their frequencies in the population.”

“In general, the larger the breeding population, the slower the rate of evolution.”

“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.”

“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?”

“It's like in biological evolution: The population will evolve, even though individuals can't. The same thing happens in the corporate world: The population of business units within corporations evolves, even though individual business units can't. That's because the capabilities of business units reside in their processes and their values, and by their very nature, processes and values are inflexible and meant not to change.”

“Venezuela, Bolivia and Ecuador lived through times of cruel and ruthless capitalism where the workers, the masses of the population, saw themselves living in a precarious state of employment and subsistence conditions. The impact of this reality took hold and impacted the evolution of the social situation of those countries and even though that produced movements that were not exactly political movements but social movements.”

“Speciation does not necessarily promote evolutionary change; rather, speciation 'gathers in' and guards evolutionary change by locking and stabilization for sufficient geological time within a Darwinian individual of the appropriate scale. If a change in a local population does not gain such protection, it becomes-to borrow Dawkins's metaphor at a macroevolutionary scale-a transient duststorm in the desert of time, a passing cloud without borders, integrity, or even the capacity to act as a unit of selection, in the panorama of life's phylogeny.”

“The literal record was not a hopelessly and imperfect fraction of truly insensible gradation within large populations but an accurate reflection of the actual process identified by evolutionists as the chief motor of biological change. The theory of punctuated equilibrium was, in its initial formulation, little more than this insight adumbrated.”

“A new species develops if a population which has become geographically isolated from its parental species acquires during this period of isolation characters which promote or guarantee reproductive isolation when the external barriers break down.”

“A species consists of a group of populations which replace each other geographically or ecologically and of which the neighboring ones integrate or hybridise wherever they are in contact or which are potentially capable of doing so (with one or more of the populations) in those cases where contact is prevented by geographical or ecological barriers.”

“Biology is a science of three dimensions. The first is the study of each species across all levels of biological organization, molecule to cell to organism to population to ecosystem. The second dimension is the diversity of all species in the biosphere. The third dimension is the history of each species in turn, comprising both its genetic evolution and the environmental change that drove the evolution. Biology, by growing in all three dimensions, is progressing toward unification and will continue to do so.”

“The proof given by Wright, that non-adaptive differentiation will occur in small populations owing to "drift," or the chance fixation of some new mutation or recombination, is one of the most important results of mathematical analysis applied to the facts of neo-mendelism. It gives accident as well as adaptation a place in evolution, and at one stroke explains many facts which puzzled earlier selectionists, notably the much greater degree of divergence shown by island than mainland forms, by forms in isolated lakes than in continuous river-systems.”

“Paleontologists had long been aware of a seeming contradiction between Darwin's postulate of gradualism, confirmed by the work of population genetics, and the actual findings of paleontology. Following phyletic lines through time seemed to reveal only minimal gradual changes but no clear evidence for any change of a species into a different genus or for the gradual origin of an evolutionary novelty. Anything truly novel always seemed to appear quite abruptly in the fossil record.”

“I find that because of modern technological evolution and our global economy, and as a result of the great increase in population, our world has greatly changed: it has become much smaller. However, our perceptions have not evolved at the same pace; we continue to cling to old national demarcations and the old feelings of 'us' and 'them'.”

“Asian Homo erectus died without issue and does not enter our immediate ancestry (for we evolved from African populations); Neanderthal people were collateral cousins, perhaps already living in Europe while we emerged in Africa... In other words, we are an improbable and fragile entity, fortunately successful after precarious beginnings as a small population in Africa, not the predictable end result of a global tendency. We are a thing, an item of history, not an embodiment of general principles.”

“We add that it would be all too easy to object that mutations have no evolutionary effect because they are eliminated by natural selection. Lethal mutations (the worst kind) are effectively eliminated, but others persist as alleles. ...Mutants are present within every population, from bacteria to man. There can be no doubt about it. But for the evolutionist, the essential lies elsewhere: in the fact that mutations do not coincide with evolution.”
