Stephen Jay Gould fue un paleontólogo estadounidense, geólogo, biólogo evolutivo, historiador de la ciencia y uno de los más influyentes y leídos divulgadores científicos de su generación.[1]​

Gould pasó la mayor parte de su carrera docente en la Universidad de Harvard y trabajando en el Museo Americano de Historia Natural de Nueva York. En los últimos años de su vida, impartió clases de biología y evolución en la Universidad de Nueva York, cercana a su residencia en el SoHo.

La mayor contribución de Gould a la ciencia fue la teoría del equilibrio puntuado que desarrolló con Niles Eldredge en 1972.[2]​ La teoría propone que la mayoría de los procesos evolutivos están compuestos por largos períodos de estabilidad, interrumpidos por episodios cortos y poco frecuentes de bifurcación evolutiva. La teoría contrasta con el gradualismo filogenético, la idea generalizada de que el cambio evolutivo se caracteriza por un patrón homogéneo y continuo.

La mayor parte de la investigación empírica de Gould se basó en los géneros de caracoles terrestres Poecilozonites y Cerion y además contribuyó a la biología evolutiva del desarrollo. En su teoría evolutiva se opuso al seleccionismo estricto, la sociobiología aplicada a seres humanos y la psicología evolucionista. Hizo campaña contra el creacionismo y propuso que la ciencia y la religión sean considerados dos ámbitos distintos, o «magisterios», cuyas autoridades no se superponen .[3]​

Muchos de los ensayos de Gould para la revista Natural History fueron reimpresos en libros entre los que sobresalen Desde Darwin y El pulgar del panda. Sus tratados más populares incluyen libros como La falsa medida del hombre, La vida maravillosa y La grandeza de la vida. Poco tiempo antes de su muerte, Gould publicó un largo tratado recapitulando su versión de la teoría evolutiva moderna llamado La estructura de la teoría de la evolución . Wikipedia

Frases célebres de Stephen Jay Gould

“Puede que cantidades considerables de cambios genéticos no estén sujetos a la selección natural y puede que se esparzan aleatoriamente [al azar] por las poblaciones.”

Stephen Jay Gould

“La vida es un arbusto de abundante ramificación, continuamente podado por el inexorable ángel de la muerte de la extinción, no una predecible escalera de progreso.”

“[En historia natural, ] un gran descubrimiento a menudo requiere un mapa hacia una mina llena de tesoros ocultos entonces fácilmente recogidos con las herramientas convencionales, no una nueva y brillante máquina de la era espacial para penetrar en los mundos que antes eran inaccesibles.”

“El hecho de la evolución está tan bien establecido como cualquier otro en la ciencia (tan seguro como la traslación de la Tierra alrededor del Sol).”

“Bien, la evolución es una teoría. También es un hecho. Y hechos y teorías son cosas diferentes, no peldaños en una jerarquía de certeza creciente. Los hechos son los datos del mundo. Las teorías son estructuras de ideas que explican e interpretan los hechos. Los hechos no se marchan cuando los científicos debaten teorías rivales para explicarlos. La teoría de gravitación de Einstein reemplazó a la de Newton en este siglo, pero las manzanas no se quedaron suspendidas en el aire esperando el resultado. Y los humanos evolucionaron de ancestros tipo monos ya sea que lo hicieron mediante el mecanismo propuesto por Darwin o por algún otro no descubierto aún.”

Stephen Jay Gould: Frases en inglés

“Science is a method for testing claims about the natural world, not an immutable compendium of absolute truths. The fundamentalists, by "knowing" the answers before they start, and then forcing nature into the straitjacket of their discredited preconceptions, lie outside the domain of science—or of any honest intellectual inquiry.”

“Gaskell could not abide this indecorous version of his beloved linear progress theory. He could not bear to imagine that the grand procession from jellyfish to man, orchestrated by an ever-increasing mass of nervous tissue, once paused in its stately and orderly march toward human consciousness in order to execute a fancy little flip, a clever jig of inversion, just at the sublime and definitive moment of entrance into the vertebral home stretch.”

“And, in this case, science could learn an important lesson from the literati — who love contingency for the same basic reason that scientists tend to regard the theme with suspicion. Because, in contingency lies the power of each person, to make a difference in an unconstrained world bristling with possibilities, and nudgeable by the smallest of unpredictable inputs into markedly different channels spelling either vast improvement or potential disaster.”

“Organisms […] are directed and limited by their past. They must remain imperfect in their form and function, and to that extent unpredictable since they are not optimal machines. We cannot know their future with certainty, if only because a myriad of quirky functional shifts lie within the capacity of any feature, however well adapted to a present role.”

“All life on earth - everything from bacteria to mushrooms to hippos - shares an astonishing range of detailed biochemical similarities, including the structure of heredity in DNA and RNA, and the universal use of ATP as an energy-storing compound. Two possible scenarios, with markedly different implications for the nature of life, might explain these regularities: either all earthly life shares these features because no other chemistry can work, or these similarities only record the common descent of all organisms on earth from a single origin that happened to feature this chemistry as one possibility among many.”

“Iconography becomes even more revealing when processes or concepts, rather than objects, must be depicted—for the constraint of a definite “thing” cedes directly to the imagination. How can we draw “evolution” or “social organization,” not to mention the more mundane “digestion” or “self-interest,” without portraying more of a mental structure than a physical reality? If we wish to trace the history of ideas, iconography becomes a candid camera trained upon the scholar's mind.”

“I contend that the continued racial classification of Homo sapiens represents an outmoded approach to the general problem of differentiation within a species. In other words, I reject a racial classification of humans for the same reasons that I prefer not to divide into subspecies the prodigiously variable West Indian land snails that form the subject of my own research.”

“Theories rarely arise as patient inferences forced by accumulated facts. Theories are mental constructs potentiated by complex external prods (including, in idealized cases, a commanding push from empirical reality). But the prods often include dreams, quirks, and errors—just as we may obtain crucial bursts of energy from foodstuffs or pharmaceuticals of no objective or enduring value. Great truth can emerge from small error. Evolution is thrilling, liberating, and correct. And Macrauchenia is a litoptern.”

“In return for this great gift that I could not repay in a thousand lifetimes, at least I can promise that, although I have frequently advanced wrong, or even stupid, arguments (in the light of later discoveries), at least I have never been lazy, and have never betrayed your trust by cutting corners or relying on superficial secondary sources. I have always based these essays upon original works in their original languages (with only two exceptions, when Fracastoro's elegant Latin verse and Beringer's foppish Latin pseudocomplexities eluded my imperfect knowledge of this previously universal scientific tongue).”

“The skein of human continuity must often become this tenuous across the centuries (hanging by a thread, in the old cliché), but the circle remains unbroken if I can touch the ink of Lavoisier's own name, written by his own hand. A candle of light, nurtured by the oxygen of his greatest discovery, never burns out if we cherish the intellectual heritage of such unfractured filiation across the ages. We may also wish to contemplate the genuine physical thread of nucleic acid that ties each of us to the common bacterial ancestor of all living creatures, born on Lavoisier's ancienne terre more than 3.5 billion years ago—and never since disrupted, not for one moment, not for one generation. Such a legacy must be worth preserving from all the guillotines of our folly.”

“The silliest and most tendentious of baseball writing tries to wrest profundity from the spectacle of grown men hitting a ball with a stick by suggesting linkages between the sport and deep issues of morality, parenthood, history, lost innocence, gentleness, and so on, seemingly ad infinitum. (The effort reeks of silliness because baseball is profound all by itself and needs no excuses; people who don't know this are not fans and are therefore unreachable anyway.)”

“South America had been an island continent, far bigger and far more diverse than Australia, for tens of millions of years before the Isthmus of Panama rose just a couple of million years ago. The resulting flood of North American mammals across the new land bridge corresponds in time with the decimation of the native South American fauna. In fact, most large mammals generally considered distinctly South American… are all recent migrants from North America.”

“Since we proposed punctuated equilibria to explain trends, it is infuriating to be quoted again and again by creationists—whether through design or stupidity, I do not know—as admitting that the fossil record includes no transitional forms. Transitional forms are generally lacking at the species level, but they are abundant between larger groups.”

“[T]his theme of mutually invisible life at widely differing scales bears an important implication for the “culture wars” that supposedly now envelop our universities and our intellectual discourse in general […]. One side of this false dichotomy features the postmodern relativists who argue that all culturally bound modes of perception must be equally valid, and that no factual truth therefore exists. The other side includes the benighted, old-fashioned realists who insist that flies truly have two wings, and that Shakespeare really did mean what he thought he was saying. The principle of scaling provides a resolution for the false parts of this silly dichotomy. Facts are facts and cannot be denied by any rational being. (Often, facts are also not at all easy to determine or specify—but this question raises different issues for another time.) Facts, however, may also be highly scale dependent—and the perceptions of one world may have no validity or expression in the domain of another. The one-page map of Maine cannot recognize the separate boulders of Acadia, but both provide equally valid representations of a factual coastline.”

“Each of the major sciences has contributed an essential ingredient in our long retreat from an initial belief in our own cosmic importance. Astronomy defined our home as a small planet tucked away in one corner of an average galaxy among millions; biology took away our status as paragons created in the image of God; geology gave us the immensity of time and taught us how little of it our own species has occupied.”
