Mathematics is as little a science as grammar is a language. Ernst Mayr More Quotes by Ernst Mayr More Quotes From Ernst Mayr Every politician, clergyman, educator, or physician, in short, anyone dealing with human individuals, is bound to make grave mistakes if he ignores these two great truths of population zoology: (1) no two individuals are alike, and (2) both environment and genetic endowment make a contribution to nearly every trait. Ernst Mayr physicians mistake two Our understanding of the world is achieved more effectively by conceptual improvements than by discovery of new facts Ernst Mayr society understanding discovery All interpretations made by a scientist are hypotheses, and all hypotheses are tentative. They must forever be tested and they must be revised if found to be unsatisfactory. Hence, a change of mind in a scientist, and particularly in a great scientist, is not only not a sign of weakness but rather evidence for continuing attention to the respective problem and an ability to test the hypothesis again and again. Ernst Mayr mind forever science Evolution as such is no longer a theory for a modern author. It is as much a fact as that the earth revolves around the sun. Ernst Mayr atheism society earth Life is simply the reification of the process of living. Ernst Mayr society process life-is I have the honesty to say I'm an Atheist. There is nothing that supports the idea of a personal God. Ernst Mayr honesty atheist ideas On the other hand, famous evolutionists such as Dobzhansky were firm believers in a personal God. He would work as a scientist all week and then on Sunday get down on his knees and pray to God. Frankly I've never been able to understand it because you would need two totally different compartments in your brain, one that deals with religion and the other with everything else. Ernst Mayr sunday two hands The history of science knows scores of instances where an investigator was in the possession of all the important facts for a new theory but simply failed to ask the right questions. Ernst Mayr important theory facts A species is a reproductive community of populations reproductively isolated from others that occupies a specific niche in nature. Ernst Mayr community nature science most scientific problems are far better understood by studying their history than their logic. Ernst Mayr logic society study The major novelty of my theory was its claim that the most rapid evolutionary change does not occur in widespread, populous species, as claimed by Most geneticists, but in small founder populations. Ernst Mayr novelty population doe According to the concept of transformational evolution, first clearly articulated by Lamarck, evolution consists of the gradual transformation of organisms from one condition of existence to another. Ernst Mayr transformation evolution firsts Evolution, thus, is merely contingent on certain processes articulated by Darwin: variation and selection. No longer is a fixed object transformed, as in transformational evolution, but an entirely new start is, so to speak, made in every generation. Ernst Mayr new-start variation generations On Earth, among millions of lineages or organisms and perhaps 50 billion speciation events, only one led to high intelligence ; this makes me believe its utter improbablity. Ernst Mayr events earth believe The most consequential change in man's view of the world, of living nature and of himself came with the introduction, over a period of some 100 years beginning only in the 18th century, of the idea of change itself, of change over periods of time: in a word, of evolution. Ernst Mayr nature men science 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. Ernst Mayr population groups science There is more to biology than rats, Drosophila, Caenorhabditis, and E. coli. Ernst Mayr biology rats 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. Ernst Mayr population different long I feel that one species, mankind, doesn't have the right to exterminate Ernst Mayr species mankind feels anyone who writes about "Darwin's theory of evolutionin the singular, without segregating the theories of gradual evolution, common descent, speciation, and the mechanism of natural selection, will be quite unable to discuss the subject competently.
