Ernst Mayr Quotes

I did not claim that speciation occurs only in founder populations Picture Quote #1

Scientific progress consists in the development of new concepts Picture Quote #1

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 Picture Quote #1

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 Picture Quote #1

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 Picture Quote #1

Life is simply the reification of the process of living Picture Quote #1

I feel that one species, mankind, doesn’t have the right to exterminate Picture Quote #1

Most scientific problems are far better understood by studying their history than their logic Picture Quote #1

Mathematics is as little a science as grammar is a language Picture Quote #1

Given the fact of evolution, one would expect the fossils to document a gradual steady change from ancestral forms to the descendants. But this is not what the paleontologist finds. Instead, he or she finds gaps in just about every phyletic series Picture Quote #1

To take an unequivocal stand, it seems to me, is of greater heuristic value and far more likely to stimulate constructive criticism than to evade the issue Picture Quote #1

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 Picture Quote #1

Our understanding of the world is achieved more effectively by conceptual improvements than by discovery of new facts Picture Quote #1

There are a number of attributes of species and populations that are not of any particular selective advantage to any single individual in a population but that are of great advantage to the population as a whole Picture Quote #1

A species is a reproductive community of populations reproductively isolated from others that occupies a specific niche in nature Picture Quote #1

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 Picture Quote #1

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 Picture Quote #1

All I claimed was that when a drastic change occurs, it occurs in a relatively small and isolated population Picture Quote #1

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 Picture Quote #1

Living in an entirely different physical as well as biotic environment, such a population would have unique opportunities to enter new niches and to select novel adaptive pathways Picture Quote #1

It is curious how often erroneous theories have had a beneficial effect for particular branches of science Picture Quote #1

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 Picture Quote #1

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 Picture Quote #1

New gene pools are generated in every generation, and evolution takes place because the successful individuals produced by these gene pools give rise to the next generation Picture Quote #1

Indeed, I was unable to find any evidence whatsoever of the occurrence of a drastic evolutionary acceleration and genetic reconstruction in widespread, populous species Picture Quote #1
