Ernst Mayr's Profile
Brief about Ernst Mayr: By info that we know Ernst Mayr was born at 1904-07-05. And also Ernst Mayr is German Scientist.Ernst Mayr's quotation" section for more.
It seems to me that for Darwin the pulsing of evolutionary rates was a strictly vertical phenomenon.Tags: Darwin, Phenomenon, Seems
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.Tags: Friendship, Life, Society
All I claimed was that when a drastic change occurs, it occurs in a relatively small and isolated population.Tags: Change, Population, Small
Evolution thus is merely contingent on certain processes articulated by Darwin: variation and selection.Tags: Evolution, Merely, Selection
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.Tags: Another, Evolution, Existence
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.Tags: Change, Fact, Quite
I had found again and again that the most aberrant population of a species - often having reached species rank, and occasionally classified even as a separate genus - occurred at a peripheral location, indeed usually at the most isolated peripheral location.Tags: Again, Found, Often
Indeed, I was unable to find any evidence whatsoever of the occurrence of a drastic evolutionary acceleration and genetic reconstruction in widespread, populous species.Tags: Evidence, Genetic, Indeed
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.Tags: Living, Physical, Unique
Most of them are doomed to rapid extinction, but a few may make evolutionary inventions, such as physiological, ecological, or behavioral innovations that give these species improved competitive potential.Tags: Few, Give, May
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.Tags: Give, Place, Successful
