Look in the mirror, and don't be tempted to equate transient domination with either intrinsic superiority or prospects for extended survival. Stephen Jay Gould More Quotes by Stephen Jay Gould More Quotes From Stephen Jay Gould Is uniformitarianism necessary? Stephen Jay Gould Natural selection is a theory of local adaptation to changing environments. It proposes no perfecting principles, no guarantee of general improvement Stephen Jay Gould changing-environmentprinciplesguarantees ...we must be wary of granting too much power to natural selection by viewing all basic capacities of our brain as direct adaptations. Stephen Jay Gould too-much-poweradaptationbrain The median isn't the message. Stephen Jay Gould medianstatisticianmessages I like to summarize what I regard as the pedestal-smashing messages of Darwin's revolution in the following statement, which might be chanted several times a day, like a Hare Krishna mantra, to encourage penetration into the soul: Humans are not the end result of predictable evolutionary progress, but rather a fortuitous cosmic afterthought. Stephen Jay Gould fortuitouscosmicatheism I was lucky to wander into evolutionary theory, one of the most exciting and important of all scientific fields. I had never heard of it when I started at a rather tender age; I was simply awed by dinosaurs. I thought paleontologists spent their lives digging up bones and putting them together, never venturing beyond the momentous issue of what connects to what. Then I discovered evolutionary theory. Ever since then, the duality of natural history-richness in particularities and potential union in underlying explanation-has propelled me. Stephen Jay Gould issuesatheismimportant [T]he effects of general change [in literature] are most tellingly recorded not in alteration of the best products, but in the transformation of the most ordinary workaday books; for when potboilers adopt the new style, then the revolution is complete. Stephen Jay Gould styleordinarybook 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.) Stephen Jay Gould airplanepowerfulmen I believe that we can still have a genre of scientific books suitable for and accessible alike to professionals and interested laypeople. The concepts of science, in all their richness and ambiguity, can be presented without any compromise, without any simplification counting as distortion, in language accessible to all intelligent people. I hope that this book can be read with profit both in seminars for graduate students and if the movie stinks and you forgot your sleeping pills on the businessman's special to Tokyo. Stephen Jay Gould sleepbelievebook There is no gene "for" such unambiguous bits of morphology as your left kneecap or your fingernail. [...] Hundreds of genes contribute to the building of most body parts and their action is channeled through a kaleidoscopic series of environmental influences: embryonic and postnatal, internal and external. Parts are not translated genes, and selection doesn't even work directly on parts. Stephen Jay Gould environmentalbodyaction As 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. Stephen Jay Gould graduatesstudentstoday Complex organisms cannot be construed as the sum of their genes, nor do genes alone build particular items of anatomy or behavior by themselves. Most genes influence several aspects of anatomy and behavior as they operate through complex interactions with other genes and their products, and with environmental factors both within and outside the developing organism. We fall into a deep error, not just a harmful oversimplification, when we speak of genes "for" particular items of anatomy or behavior. Stephen Jay Gould interaction-with-otherserrorsfall I despair of persuading people to drop the familiar and comforting tactic of dichotomy. Perhaps, instead, we might expand the framework of debates by seeking other dichotomies more appropriate than, or simply different from, the conventional divisions. All dichotomies are simplifications, but the rendition of a conflict along differing axes of several orthogonal dichotomies might provide an amplitude of proper intellectual space without forcing us to forgo our most comforting tool of thought. Stephen Jay Gould axesspacepeople Hyper-selectionism has been with us for a long time in various guises; for it represents the late nineteenth century's scientific version of the myth of natural harmony all is for the best in the best of all possible worlds (all structures well designed for a definite purpose in this case). It is, indeed, the vision of foolish Dr. Pangloss, so vividly satirized by Voltaire in Candide the world is not necessarily good, but it is the best we could possibly have. Stephen Jay Gould drsvisionlong 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.

And yet the dinoflagellates do seem to be killing and eating fishes in a manner suggesting active evolution for this most peculiar reversal. Stephen Jay Gould benefitscellspeculiar
