Ernst Mayr Quotes

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.

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.

This new consensus seemed so compelling that Ernst Mayr, the dean of modern Darwinians, opened the ashcan of history for a deposit of Geoffrey's ideas about anatomical unity.

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.

The searching human mind is not satisfied merely to discover facts. We also want to know how things happen and why.

Truly, Buffon was the father of all thought in natural history in the second half of the 18th century.

A plant on the edge of a desert is said to struggle for life against the drought, though more properly it should be said to be dependent on the moisture

And it is this randomness of variation that is responsible for the enormous, often quite bizarre diversity of the living world.

No amphibian succeeded in adapting to salt water.

No one could have predicted that a defenseless, slow-moving biped should become the pinnacle of Creation.

Furthermore, it is observed in general that the smaller the population size of a species is, the more vulnerable it will be to extinction.

The funny thing is if in England, you ask a man in the street who the greatest living Darwinian is, he will say Richard Dawkins. And indeed, Dawkins has done a marvelous job of popularizing Darwinism. But Dawkins' basic theory of the gene being the object of evolution is totally non-Darwinian.

Actually, the entire ascent of life can be presented as an adaptive radiation in the time dimension. From the beginning of replicating molecules to the formation of membrane-bounded cells, the formation of chromosomes, the origin of nucleated eukaryotes, the formation of multicellular organisms, the rise of endothermy, and the evolution of a large and highly complex central nervous system, each of these steps permitted the utilization of a different set of environmental resources, that is, the occupation of a different adaptive zone.

To use the molecular clock in such a way requires the calibration of its “ticking rate.

This uneven rate of evolution of different properties of an organism is called mosaic evolution , and it may create difficulties for classification.

The principle of adaptationism has been adopted so widely by Darwinians because it is such a heuristic methodology.

The final proof as to whether a certain habitat form has a genetic basis or is entirely phenotypical can be found only through experiments.

Over the past sixty years a rather impressive assembly of respectable taxonomists and evolutionary biologists have tried to unseat the biological species concept for a wide variety of reasons. Most of them failed, probably because Ernst Mayr is alive, adroit, and articulate at ninety-six years young as I write these words, and most critics are no match for him.

I published that theory [of speciational evolution] in a 1954 paper…and I clearly related it to paleontology. Darwin argued that the fossil record is very incomplete because some species fossilize better than others... I noted that you are never going to find evidence of a small local population that changed very rapidly in the fossil record... Gould was my course assistant at Harvard where I presented this theory again and again for three years. So he knew it thoroughly. So did Eldredge. In fact, in his 1971 paper Eldredge credited me with it. But that was lost over time.

Therefore, it came as a terrible shock to the Victorian age when Darwin, following his theory of common descent, incorporated the human species into the animal kingdom as a descendant of primate ancestors.

Some insignificant and probably nocturnal mammals also survived and experienced in the Paleocene and Eocene a spectacular radiation, producing all the orders and many of the families of the now living mammals.

Generalizations in biology are almost invariably of a probabilistic nature. As one wit has formulated it, there is only one universal law in biology: 'All biological laws have exceptions.' This probabilistic conceptualization contrasts strikingly with the view during the early period of the scientific revolution that causation in nature is regulated by laws that can be stated in mathematical terms. Actually, this idea occurred apparently first to Pythagoras. It has remained a dominant idea, particularly in the physical sciences, up to the present day. Again and again it was made the basis of some comprehensive philosophy, but taking very different forms in the hands of various authors. With Plato it gave rise to essentialism, with Galileo to a mechanistic world picture, and with Descartes to the deductive method. All three philosophies had a fundamental impact on biology.

In his history of biology, Ernst Mayr showed that many biologists originally rejected the theory of natural selection because of their belief that a species was a pure type defined by an essence. They could not wrap their minds around the concept that species are populations of variable individuals and that one can blend into another over evolutionary time.36 In this context, the fear of genetically modified foods no longer seems so strange: it is simply the standard human intuition that every living thing has an essence. Natural foods are thought to have the pure essence of the plant or animal and to carry with them the rejuvenating powers of the pastoral environment in which they grew. Genetically modified foods, or foods containing artificial additives, are thought of as being deliberately laced with a contaminant tainted by its origins in an acrid laboratory or factory. Arguments that invoke genetics, biochemistry, evolution, and risk analysis are likely to fall on deaf ears when pitted against this deep-rooted way of thinking.

{On to contributions to evolutionary biology of 18th century French scientist, Georges-Louis Leclerc, Comte de Buffon} He was not an evolutionary biologist, yet he was the father of evolutionism. He was the first person to discuss a large number of evolutionary problems, problems that before Buffon had not been raised by anybody.... he brought them to the attention of the scientific world. Except for Aristotle and Darwin, no other student of organisms [whole animals and plants] has had as far-reaching an influence. He brought the idea of evolution into the realm of science. He developed a concept of the "unity of type", a precursor of comparative anatomy. More than anyone else, he was responsible for the acceptance of a long-time scale for the history of the earth. He was one of the first to imply that you get inheritance from your parents, in a description based on similarities between elephants and mammoths. And yet, he hindered evolution by his frequent endorsement of the immutability of species. He provided a criterion of species, fertility among members of a species, that was thought impregnable.

he importance and influence of Charles Darwin’s theory of evolution by natural selection can scarcely be exaggerated. A century after Darwin’s death, the great evolutionary biologist and historian of science, Ernst Mayr, wrote, ‘The worldview formed by any thinking person in the Western world after 1859, when On the Origin of Species was published, was by necessity quite different from a worldview formed prior to 1859… The intellectual revolution generated by Darwin went far beyond the confines of biology, causing the overthrow of some of the most basic beliefs of his age.’1 Adrian Desmond and James Moore, Darwin’s biographers, contend, ‘Darwin is arguably the best known scientist in history. More than any modern thinker—even Freud or Marx—this affable old-world naturalist from the minor Shropshire gentry has transformed the way we see ourselves on the planet.’2 In the words of the philosopher Daniel C. Dennett, ‘Almost no one is indifferent to Darwin, and no one should be. The Darwinian theory is a scientific theory, and a great one, but that is not all it is… Darwin’s dangerous idea cuts much deeper into the fabric of our most fundamental beliefs than many of its sophisticated apologists have yet admitted, even to themselves.’3 Dennett goes on to add, ‘If I were to give an award for the single best idea anyone has ever had, I’d give it to Darwin, ahead of Newton and Einstein and everyone else. In a single stroke, the idea of evolution by natural selection unifies the realm of life, meaning, and purpose with the realm of space and time, cause and effect, mechanism and physical law.’4 The editors of the Cambridge Companion to Darwin begin their introduction by stating, ‘Some scientific thinkers, while not themselves philosophers, make philosophers necessary. Charles Darwin is an obvious case. His conclusions about the history and diversity of life—including the evolutionary origin of humans—have seemed to bear on fundamental questions about being, knowledge, virtue and justice.’5 Among the fundamental questions raised by Darwin’s work, which are still being debated by philosophers (and others) are these: ‘Are we different in kind from other animals? Do our apparently unique capacities for language, reason and morality point to a divine spark within us, or to ancestral animal legacies still in evidence in our simian relatives? What forms of social life are we naturally disposed towards—competitive and selfish forms, or cooperative and altruistic ones?’6 As the editors of the volume point out, virtually the entire corpus of the foundational works of Western philosophy, from Plato and Aristotle to Descartes to Kant to Hegel, has had to be re-examined in the light of Darwin’s work. Darwin continues to be read, discussed, interpreted, used, abused—and misused—to this day. As the philosopher and historian of science, Jean Gayon, puts it, ‘[T]his persistent positioning of new developments in relation to a single, pioneering figure is quite exceptional in the history of modern natural science.

The Tale of Human Evolution The subject most often brought up by advocates of the theory of evolution is the subject of the origin of man. The Darwinist claim holds that modern man evolved from ape-like creatures. During this alleged evolutionary process, which is supposed to have started 4-5 million years ago, some "transitional forms" between modern man and his ancestors are supposed to have existed. According to this completely imaginary scenario, four basic "categories" are listed: 1. Australopithecus 2. Homo habilis 3. Homo erectus 4. Homo sapiens Evolutionists call man's so-called first ape-like ancestors Australopithecus, which means "South African ape." These living beings are actually nothing but an old ape species that has become extinct. Extensive research done on various Australopithecus specimens by two world famous anatomists from England and the USA, namely, Lord Solly Zuckerman and Prof. Charles Oxnard, shows that these apes belonged to an ordinary ape species that became extinct and bore no resemblance to humans. Evolutionists classify the next stage of human evolution as "homo," that is "man." According to their claim, the living beings in the Homo series are more developed than Australopithecus. Evolutionists devise a fanciful evolution scheme by arranging different fossils of these creatures in a particular order. This scheme is imaginary because it has never been proved that there is an evolutionary relation between these different classes. Ernst Mayr, one of the twentieth century's most important evolutionists, contends in his book One Long Argument that "particularly historical [puzzles] such as the origin of life or of Homo sapiens, are extremely difficult and may even resist a final, satisfying explanation." By outlining the link chain as Australopithecus > Homo habilis > Homo erectus > Homo sapiens, evolutionists imply that each of these species is one another's ancestor. However, recent findings of paleoanthropologists have revealed that Australopithecus, Homo habilis, and Homo erectus lived at different parts of the world at the same time. Moreover, a certain segment of humans classified as Homo erectus have lived up until very modern times. Homo sapiens neandarthalensis and Homo sapiens sapiens (modern man) co-existed in the same region. This situation apparently indicates the invalidity of the claim that they are ancestors of one another. Stephen Jay Gould explained this deadlock of the theory of evolution although he was himself one of the leading advocates of evolution in the twentieth century: What has become of our ladder if there are three coexisting lineages of hominids (A. africanus, the robust australopithecines, and H. habilis), none clearly derived from another? Moreover, none of the three display any evolutionary trends during their tenure on earth. Put briefly, the scenario of human evolution, which is "upheld" with the help of various drawings of some "half ape, half human" creatures appearing in the media and course books, that is, frankly, by means of propaganda, is nothing but a tale with no scientific foundation. Lord Solly Zuckerman, one of the most famous and respected scientists in the U.K., who carried out research on this subject for years and studied Australopithecus fossils for 15 years, finally concluded, despite being an evolutionist himself, that there is, in fact, no such family tree branching out from ape-like creatures to man.

Ernst Mayr characterized the Cartesian view of animals as dumb automatons.2

around, some microbiologists have suggested that classifying bacteria by species is futile. It seems as if all bacteria belong to one mega-species, and different strains within this species differ by the genes they express and the genes they repress. By classifying bacteria into a single species, all bacteria would obey the definition for a species first proposed by Ernst Mayr in 1942: Members of the same species

Darwin completely rejected typological thinking and introduced instead the entirely different concept now called population thinking. All groupings of living organisms, including humanity, are populations that consist of uniquely different individuals. By rejecting the constancy of populations, Darwin helped to introduce history into scientific thinking and to promote a distinctly new approach to explanatory interpretation in science.

Might human sapience be a fluke? Evolutionary biologist Ernst Mayr said—“Nothing demonstrates the improbability of high intelligence better than the fifty billion earthly species that failed to achieve it.

Equality in spite of evident nonidentity is a somewhat sophisticated concept and requires a moral stature of which many individuals seem to be incapable.

Ernst Mayr asserted that “it would be difficult to refute the claim that the Darwinian revolution was the greatest of all intellectual revolutions in the history of mankind.” Stephen Jay Gould called the theory of evolution one of the half dozen most important ideas in the entire history of Western thought. Richard Dawkins inquired what common ground we could find for conversation with an extraterrestrial intelligence, and answered “evolution”—because it is “a universal truth” that is common throughout the cosmos.

Daedalus Winter 2002. Vol. 131, pg. 89 The Biology of Race and the Concept of Equality. Ernst Mayr There is a widespread feeling that the word "race" indicates something undesirable and that it should be left out of all discussions. This leads to such statements as "there are no human races." Those who subscribe to this opinion are obviously ignorant of modern biology. Races are not something specifically human; races occur in a large percentage of species of animals. You can read in every textbook on evolution that geographic races of animals, when isolated from other races of their species, may in due time become new species. The terms "subspecies" and "geographic race" are used interchangeably in this taxonomic literature. … In a recent textbook of taxonomy, I defined a "geographic race" or subspecies as "an aggregate of phenotypically similar populations of a species inhabiting a geographic subdivision of the range of that species and differing taxonomically from other populations of that species." A subspecies is a geographic race that is sufficiently different taxonomically to be worthy of a separate name. What is characteristic of a geographic race is, first, that it is restricted to a geographic subdivision of the range of a species, and second, that in spite of certain diagnostic differences, it is part of a larger species. No matter what the cause of the racial difference might be, the fact that species of organisms may have geographic races has been demonstrated so frequently that it can no longer be denied. And the geographic races of the human races established before the voyages of European discovery and subsequent rise of a global economy - agree in most characteristics with the geographic races of animals. Recognizing races is only recognizing a biological fact. from Wikipedia: Ernst Mayr Ernst Walter Mayr was one of the 20th century's leading evolutionary biologists. He was also a renowned taxonomist, tropical explorer, ornithologist, philosopher of biology, and historian of science. His work contributed to the conceptual revolution that led to the modern evolutionary synthesis of Mendelian genetics, systematics, and Darwinian evolution, and to the development of the biological species concept.

La división del trabajo nos hace más eficaces.
