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.
Some Ernst Mayr's quotes. Goto "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, SeemsIn 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, SocietyAll I claimed was that when a drastic change occurs, it occurs in a relatively small and isolated population.
Tags: Change, Population, SmallEvolution thus is merely contingent on certain processes articulated by Darwin: variation and selection.
Tags: Evolution, Merely, SelectionAccording 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, ExistenceAs 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, QuiteI 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, OftenIndeed, 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, IndeedLiving 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, UniqueMost 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, MayNew 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.
