“Los dinosaurios evolucionaron hasta convertirse en pájaros.”

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).”

Fuente: Réplica de Stephen Jay Gould, en la Universidad de Harvard, al artículo de Irving Kristol en The New York Times el 30 de septiembre de 1986; fue publicada en el número de enero de 1987 de la revista de divulgación científica Discover.

“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

“The intricate and different life cycles of both male and female root-heads, and the great behavioral sophistication shown by the female in reconfiguring a host crab as a support system, all underscore the myopia of our conventional wisdom in regarding rhizocephalans as degenerate parasites because the adult anatomy of internal roots and external sac seem so simple.”

“I love these tales because, in more reasonable attributions of motive, they so beautifully embody a fundamental theme of historical explanation - that consequences of substantial import often arise from triggers of entirely different intent. In other words, current utility bears no necessary relationship with historical origin.”

“I can only look from the outside (or cut into the inside, but flesh and genes do not reveal organic totality). I am stuck with a panoply of ineluctably indirect methods - some very sophisticated to be sure. I can atomize, experiment, and infer. I can record reams of data about behaviors and responses. But if I could be a beetle or a bacillus for that one precious minute - and live to tell the tale in perfect memory - then I might truly fulfill Darwin's dictum penned into an early notebook containing the first full flowering of his evolutionary ideas during the late 1830's: "He who understands the baboon would do more towards metaphysics than Locke."”

“Wallace's error on human intellect arose from the inadequacy of his rigid selectionism, not from a failure to apply it. And his argument repays our study today, since its flaw persists as the weak link in many of the most “modern” evolutionary speculations of our current literature. For Wallace's rigid selectionism is much closer than Darwin's pluralism to the attitude embodied in our favored theory today, which, ironically in this context, goes by the name of “Neo-Darwinism.””

“This essay treats the most celebrated story in the extreme simplification in an adult parasite - in the interests of illuminating, reconciling, and, perhaps, even resolving two major biases that have so hindered our understanding of natural history: the misequation of evolution with progress, and the undervaluing of an organism by considering only its adult form and not the entire life cycle.”

“Great thinkers build their edifices with subtle consistency. We do our intellectual forebears an enormous disservice when we dismember their visions and scan their systems in order to extract a few disembodied “gems”—thoughts or claims still accepted as true. These disarticulated pieces then become the entire legacy of our ancestors, and we lose the beauty and coherence of older systems that might enlighten us by their unfamiliarity—and their consequent challenge—in our fallible (and complacent) modern world.”

“Thus, we have three principles for increasing adequacy of data: if you must work with a single object, look for imperfections that record historical descent; if several objects are available, try to render them as stages of a single historical process; if processes can be directly observed, sum up their effects through time. One may discuss these principles directly or recognize the “little problems” that Darwin used to exemplify them: orchids, coral reefs, and worms—the middle book, the first, and the last.”

“It is so hard for an evolutionary biologist to write about extinction caused by human stupidity. […] Let me then float an unconventional plea, the inverse of the usual argument. […] The extinction of Partula is unfair to Partula. That is the conventional argument, and I do not challenge its primacy. But we need a humanistic ecology as well, both for the practical reason that people will always touch people more than snails do or can, and for the moral reason that humans are legitimately the measure of all ethical questions—for these are our issues, not nature's.”

“[A]s a graduate student at Columbia University, I remember the a priori derision of my distinguished stratigraphy professor toward a visiting Australian drifter [a supporter of the theory of continental drift]. […] Today […] my own students would dismiss with even more derision anyone who denied the evident truth of continental drift—a prophetic madman is at least amusing; a superannuated fuddy-duddy is merely pitiful.”

“The oppressive weight of disaster and tragedy in our lives does not arise from a high percentage of evil among the summed total of all acts, but from the extraordinary power of exceedingly rare incidents of depravity to inflict catastrophic damage, especially in our technological age when airplanes can become powerful bombs. (An even more evil man, armed only with a longbow, could not have wreaked such havoc at the Battle of Agincourt in 1415.)”

“We build our personalities laboriously and through many years, and we cannot order fundamental changes just because we might value their utility; no button reading “positive attitude” protrudes from our hearts, and no finger can coerce positivity into immediate action by a single and painless pressing.”

“As a nation, we are too young to have true mythic heroes, and we must press real human beings into service. Honest Abe Lincoln the legend is quite a different character from Abraham Lincoln the man. And so should they be. And so should both be treasured, as long as they are distinguished. In a complex and confusing world, the perfect clarity of sports provides a focus for legitimate, utterly unambiguous support [or] disdain. The Dodgers are evil, the Yankees good. They really are, and have been for as long as anyone in my family can remember.”

“We inhabit a complex world. Some boundaries are sharp and permit clean and definite distinctions. But nature also includes continua that cannot be neatly parceled into two piles of unambiguous yeses and noes. Biologists have rejected, as fatally flawed in principle, all attempts by anti-abortionists to define an unambiguous “beginning of life,” because we know so well that the sequence from ovulation or spermatogenesis to birth is an unbreakable continuum—and surely no one will define masturbation as murder.”

“Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts do not go away while scientists debate rival theories for explaining them. Einstein's theory of gravitation replaced Newton's, but apples did not suspend themselves in mid-air pending the outcome. And human beings evolved from apelike ancestors whether they did so by Darwin's proposed mechanism or by some other, yet to be discovered. […] Evolutionists make no claim for perpetual truth, though creationists often do (and then attack us for a style of argument that they themselves favor). In science, “fact” can only mean “confirmed to such a degree that it would be perverse to withhold provisional assent.””
