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
Image
I feel that one species, mankind, doesn't have the right to exterminate
Ernst Mayr
Image
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.
Ernst Mayr
Image
In those early years in New York when I was a stranger in a big city, it was the companionship and later friendship which I was offered in the Linnean Society that was the most important thing in my life.
Ernst Mayr
Image
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
Image
It is curious how often erroneous theories have had a beneficial effect for particular branches of science.
Ernst Mayr
Image
most scientific problems are far better understood by studying their history than their logic.
Ernst Mayr
Image
There is more to biology than rats, Drosophila, Caenorhabditis, and E. coli.
Ernst Mayr
Image
Indeed, I was unable to find any evidence whatsoever of the occurrence of a drastic evolutionary acceleration and genetic reconstruction in widespread, populous species.
Ernst Mayr
Image
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
Image
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
Image
Definitions are temporary verbalizations of concepts, and concepts- particularly difficult concepts- are usually revised repeatedly as our knowledge and understanding grows.
Ernst Mayr
Image
In neither his definition nor the examples illustrating what memes are does Dawkins mention anything that would distinguish memes from concepts.
Ernst Mayr
Image
Scientific progress consists in the development of new concepts.
Ernst Mayr
Image
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.
Ernst Mayr
Image
Life is simply the reification of the process of living.
Ernst Mayr
Image
Evolution thus is merely contingent on certain processes articulated by Darwin: variation and selection.
Ernst Mayr
Image
Wherever we look at the living biota … discontinuities are overwhelmingly frequent…The discontinuities are even more striking in the fossil record. New species usually appear in the fossil record suddenly, not connected with their ancestors by a series of intermediates.
Ernst Mayr
Image
It seems to me that for Darwin the pulsing of evolutionary rates was a strictly vertical phenomenon.
Ernst Mayr
Image
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.
