Overview

The world's most revered and eloquent interpreter of evolutionary ideas offers here a work of explanatory force unprecedented in our time—a landmark publication, both for its historical sweep and for its scientific vision.

With characteristic attention to detail, Stephen Jay Gould first describes the content and discusses the history and origins of the three core commitments of classical Darwinism: that natural selection works on organisms, not genes or species; that it is almost exclusively the mechanism of adaptive evolutionary change; and that these changes are incremental, not drastic. Next, he examines the three critiques that currently challenge this classic Darwinian edifice: that selection operates on multiple levels, from the gene to the group; that evolution proceeds by a variety of mechanisms, not just natural selection; and that causes operating at broader scales, including catastrophes, have figured prominently in the course of evolution.

Then, in a stunning tour de force that will likely stimulate discussion and debate for decades, Gould proposes his own system for integrating these classical commitments and contemporary critiques into a new structure of evolutionary thought.

In 2001 the Library of Congress named Stephen Jay Gould one of America's eighty-three Living Legends—people who embody the "quintessentially American ideal of individual creativity, conviction, dedication, and exuberance." Each of these qualities finds full expression in this peerless work, the likes of which the scientific world has not seen—and may not see again—for well over a century.

Chapter One


Defining and Revising the
Structure of Evolutionary Theory


Theories Need Both Essences and Histories


In a famous passage added to later editions of the Origin of Species, Charles Darwin (1872, p. 134) generalized his opening statement on the apparent absurdity of evolving a complex eye through a long series of gradual steps by reminding his readers that they should always treat "obvious" truths with skepticism. In so doing, Darwin also challenged the celebrated definition of science as "organized common sense," as championed by his dear friend Thomas Henry Huxley. Darwin wrote: "When it was first said that the sun stood still and world turned round, the common sense of mankind declared the doctrine false; but the old saying of Vox populi, vox Dei [the voice of the people is the voice of God], as every philosopher knows, cannot be trusted in science."

    Despite his firm residence within England's higher social classes, Darwin took a fully egalitarian approach towards sources of expertise, knowing full well that the most dependable data on behavior and breeding of domesticated and cultivated organisms would be obtained from active farmers and husbandmen, not from lords of their manors or authors of theoretical treatises. As Ghiselin (1969) so cogently stated, Darwin maintained an uncompromisingly "aristocratic" set of values towards judgment of his work—that is, he cared not a whit for the outpourings of vox populi, but fretted endlessly and fearfully about the opinions of a very few key peopleblessed with the rare mix of intelligence, zeal, and attentive practice that we call expertise (a democratic human property, respecting only the requisite mental skills and emotional toughness, and bearing no intrinsic correlation to class, profession or any other fortuity of social circumstance).

    Darwin ranked Hugh Falconer, the Scottish surgeon, paleontologist, and Indian tea grower, within this most discriminating of all his social groups, a panel that included Hooker, Huxley and Lyell as the most prominent members. Thus, when Falconer wrote his important 1863 paper on American fossil elephants (see Chapter 9, pages 745-749, for full discussion of this incident), Darwin flooded himself with anticipatory fear, but then rejoiced in his critic's generally favorable reception of evolution, as embodied in the closing sentence of Falconer's key section: "Darwin has, beyond all his cotemporaries [sic], given an impulse to the philosophical investigation of the most backward and obscure branch of the Biological Sciences of his day; he has laid the foundations of a great edifice; but he need not be surprised if, in the progress of erection, the superstructure is altered by his successors, like the Duomo of Milan, from the roman to a different style of architecture."

    In a letter to Falconer on October 1, 1862 (in F. Darwin, 1903, volume 1, p. 206), Darwin explicitly addressed this passage in Falconer's text. (Darwin had received an advance copy of the manuscript, along with Falconer's request for review and criticism—hence Darwin's reply, in 1862, to a text not printed until the following year): "To return to your concluding sentence: far from being surprised, I look at it as absolutely certain that very much in the Origin will be proved rubbish; but I expect and hope that the framework will stand."

    The statement that God (or the Devil, in some versions) dwells in the details must rank among the most widely cited intellectual witticisms of our time. As with many clever epigrams that spark the reaction "I wish I'd said that!", attribution of authorship tends to drift towards appropriate famous sources. (Virtually any nifty evolutionary saying eventually migrates to T. H. Huxley, just as vernacular commentary about modern America moves towards Mr. Berra.) The apostle of modernism in architecture, Ludwig Mies van der Rohe, may, or may not, have said that "God dwells in the details," but the plethora of tiny and subtle choices that distinguish the elegance of his great buildings from the utter drabness of superficially similar glass boxes throughout the world surely validates his candidacy for an optimal linkage of word and deed.

    Architecture may assert a more concrete claim, but nothing beats the extraordinary subtlety of language as a medium for expressing the importance of apparently trivial details. The architectural metaphors of Milan's cathedral, used by both Falconer and Darwin, may strike us as effectively identical at first read. Falconer says that the foundations will persist as Darwin's legacy, but that the superstructure will probably be reconstructed in a quite different style. Darwin responds by acknowledging Falconer's conjecture that the theory of natural selection will undergo substantial change; indeed, in his characteristically diffident way, Darwin even professes himself "absolutely certain" that much of the Origin's content will be exposed as "rubbish." But he then states not only a hope, but also an expectation, that the "framework" will stand.

    We might easily read this correspondence too casually as a polite dialogue between friends, airing a few unimportant disagreements amidst a commitment to mutual support. But I think that this exchange between Falconer and Darwin includes a far more "edgy" quality beneath its diplomacy. Consider the different predictions that flow from the disparate metaphors chosen by each author for the Duomo of Milan—Falconer's "foundation" vs. Darwin's "framework." After all, a foundation is an invisible system of support, sunk into the ground, and intended as protection against sinking or toppling of the overlying public structure. A framework, on the other hand, defines the basic form and outline of the public structure itself. Thus, the two men conjure up very different pictures in their crystal balls. Falconer expects that the underlying evolutionary principle of descent with modification will persist as a factual foundation for forthcoming theories devised to explain the genealogical tree of life. Darwin counters that the theory of natural selection will persist as a basic explanation of evolution, even though many details, and even some subsidiary generalities, cited within the Origin will later be rejected as false, or even illogical.

    I stress this distinction, so verbally and disarmingly trivial at a first and superficial skim through Falconer's and Darwin's words, but so incisive and portentous as contrasting predictions about the history of evolutionary theory, because my own position—closer to Falconer than to Darwin, but in accord with Darwin on one key point—led me to write this book, while also supplying the organizing principle for the "one long argument" of its entirety. I do believe that the Darwinian framework, and not just the foundation, persists in the emerging structure of a more adequate evolutionary theory. But I also hold, with Falconer, that substantial changes, introduced during the last half of the 20th century, have built a structure so expanded beyond the original Darwinian core, and so enlarged by new principles of macroevolutionary explanation, that the full exposition, while remaining within the domain of Darwinian logic, must be construed as basically different from the canonical theory of natural selection, rather than simply extended.

    A closer study of the material basis for Falconer and Darwin's metaphors—the Duomo (or Cathedral) of Milan—might help to clarify this important distinction. As with so many buildings of such size, expense, and centrality (both geographically and spiritually), the construction of the Duomo occupied several centuries and included an amalgam of radically changing styles and purposes. Construction began at the chevet, or eastern end, of the cathedral in the late 14th century. The tall windows of the chevet, with their glorious flamboyant tracery, strike me as the finest achievement of the entire structure, and as the greatest artistic expression of this highly ornamented latest Gothic style. (The term "flamboyant" literally refers to the flame-shaped element so extensively used in the tracery, but the word then came to mean "richly decorated" and "showy," initially as an apt description of the overall style, but then extended to the more general meaning used today.)

    Coming now to the main point, construction then slowed considerably, and the main western facade and entrance way (Fig. 1-1) dates from the late 16th century, when stylistic preferences had changed drastically from the points, curves and traceries of Gothic to the orthogonal, low-angled or gently rounded lintels and pediments of classical Baroque preferences. Thus, the first two tiers of the main (western) entrance to the Duomo display a style that, in one sense, could not be more formally discordant with Gothic elements of design, but that somehow became integrated into an interesting coherence. (The third tier of the western facade, built much later, returned to a "retro" Gothic style, thus suggesting a metaphorical reversal of phylogenetic conventions, as up leads to older—in style if not in actual time of emplacement!) Finally, in a distinctive and controversial icing upon the entire structure (Fig. 1-2), the "wedding cake," or row-upon-row of Gothic pinnacles festooning the tops of all walls and arches with their purely ornamental forms, did not crown the edifice until the beginning of the 19th century, when Napoleon conquered the city and ordered their construction to complete the Duomo after so many centuries of work. (These pinnacle forests may amuse or disgust architectural purists, but no one can deny their unintended role in making the Duomo so uniquely and immediately recognizable as the icon of the city.)

    How, then, shall we state the most appropriate contrast between the Duomo of Milan and the building of evolutionary theory since Darwin's Origin in 1859? If we grant continuity to the intellectual edifice (as implied by comparison with a discrete building that continually grew but did not change its location or basic function), then how shall we conceive "the structure of evolutionary theory" (chosen, in large measure, as the title for this book because I wanted to address, at least in practical terms, this central question in the history and content of science)? Shall we accept Darwin's triumphalist stance and hold that the framework remains basically fixed, with all visually substantial change analogous to the non-structural, and literally superficial, icing of topmost pinnacles? Or shall we embrace Falconer's richer and more critical, but still fully positive, concept of a structure that has changed in radical ways by incorporating entirely different styles into crucial parts of the building (even the front entrance!), while still managing to integrate all the differences into a coherent and functional whole, encompassing more and more territory in its continuing enlargement?

    Darwin's version remains Gothic, and basically unchanged beyond the visual equivalent of lip service. Falconer's version retains the Gothic base as a positive constraint and director, but then branches out into novel forms that mesh with the base but convert the growing structure into a new entity, largely defined by the outlines of its history. (Note that no one has suggested the third alternative, often the fate of cathedrals—destruction, either total or partial, followed by a new building of contrary or oppositional form, erected over a different foundation.)

    In order to enter such a discourse about "the structure of evolutionary theory" at all, we must accept the validity, or at least the intellectual coherence and potential definability, of some key postulates and assumptions that are often not spelled out at all (especially by scientists supposedly engaged in the work), and are, moreover, not always granted this form of intelligibility by philosophers and social critics who do engage such questions explicitly. Most importantly, I must be able to describe a construct like "evolutionary theory" as a genuine "thing"—an entity with discrete boundaries and a definable history—especially if I want to "cash out," as more than a confusingly poetic image, an analogy to the indubitable bricks and mortar of a cathedral.

    In particular, and to formulate the general problem in terms of the specific example needed to justify the existence of this book, can "Darwinism" or "Darwinian theory" be treated as an entity with defining properties of "anatomical form" that permit us to specify a beginning and, most crucially for the analysis I wish to pursue, to judge the subsequent history of Darwinism with enough rigor to evaluate successes, failures and, especially, the degree and character of alterations? This book asserts, as its key premise and one long argument, that such an understanding of modern evolutionary theory places the subject in a particularly "happy" intellectual status—with the central core of Darwinian logic sufficiently intact to maintain continuity as the centerpiece of the entire field, but with enough important changes (to all major branches extending from this core) to alter the structure of evolutionary theory into something truly different by expansion, addition, and redefinition. In short, "The structure of evolutionary theory" combines enough stability for coherence with enough change to keep any keen mind in a perpetual mode of search and challenge.

    The distinction between Falconer's and Darwin's predictions, a key ingredient in my analysis, rests upon our ability to define the central features of Darwinism (its autapomorphies, if you will), so that we may then discern whether the extent of alteration in our modern understanding of evolutionary mechanisms and causes remains within the central logic of this Darwinian foundation, or has now changed so profoundly that, by any fair criterion in vernacular understanding of language, or by any more formal account of departure from original premises, our current explanatory theory must be described as a different kind of mental "thing." How, in short, can such an intellectual entity be defined? And what degree of change can be tolerated or accommodated within the structure of such an entity before we must alter the name and declare the entity invalid or overthrown? Or do such questions just represent a fool's errand from the start, because intellectual positions can't be reified into sufficient equivalents of buildings or organisms to bear the weight of such an inquiry?

    As arrogant as I may be in general, I am not sufficiently doltish or vainglorious to imagine that I can meaningfully address the deep philosophical questions embedded within this general inquiry of our intellectual ages—that is, fruitful modes of analysis for the history of human thought. I shall therefore take refuge in an escape route that has traditionally been granted to scientists: the liberty to act as a practical philistine. Instead of suggesting a principled and general solution, I shall ask whether I can specify an operational way to define "Darwinism" (and other intellectual entities) in a manner specific enough to win shared agreement and understanding among readers, but broad enough to avoid the doctrinal quarrels about membership and allegiance that always seem to arise when we define intellectual commitments as pledges of fealty to lists of dogmata (not to mention initiation rites, secret handshakes and membership cards—in short, the intellectual paraphernalia that led Karl Marx to make his famous comment to a French journalist: "je ne suis pas marxiste").

    As a working proposal, and as so often in this book (and in human affairs in general), a "Goldilocks solution" embodies the blessedly practical kind of approach that permits contentious and self-serving human beings (God love us) to break intellectual bread together in pursuit of common goals rather than personal triumph. (For this reason, I have always preferred, as guides to human action, messy hypothetical imperatives like the Golden Rule, based on negotiation, compromise and general respect, to the Kantian categorical imperatives of absolute righteousness, in whose name we so often murder and maim until we decide that we had followed the wrong instantiation of the right generality.) We must, in short and in this case, steer between the "too little" of refusing to grant any kind of "essence," or hard anatomy of defining concepts, to a theory like Darwinism; and the "too much" of an identification so burdened with a long checklist of exigent criteria that we will either spend all our time debating the status of particular items (and never addressing the heart or central meaning of the theory), or we will waste our efforts, and poison our communities, with arguments about credentials and anathemata, applied to individual applicants for membership.

Verdi's comment on hearing of the death of Wagner -- 'Sad, sad, sad!' -- should be magnified a thousand times to describe the world's loss when Stephen Jay Gould died, just 60 years young, earlier this year (2002). This book, The Structure of Evolutionary Theory, was -- as he knew -- his swan song. It is an awesome work -- the distillation and explication of a lifetime's work in biology and evolution. Gould explores the history of human thought on the origin and development of life; the astonishing insights of Charles Darwin; Darwin's critics and defenders; and the relatively modest amendments to Darwin's theories made by scientists who've enjoyed the advantages of later geologic and fossil finds. Gould's painstaking analysis and defense of 'punctuated equilibrium' -- his own, admittedly slight modfification of Darwin -- is, at least to this reader, thoroughly convincing. Creationists need not open this book: in fact, they should not open it. 'The Structure of Evolutionary Theory' will either be incomprehensible to them or it will destroy their small-minded and superstitious views of the world. I mentioned Verdi's comment on the death of Wagner. Better, perhaps, is Boito's on the death of Verdi: 'It is evil and wrong that such a great man should cease to be among us.' Indeed. The death of Stephen Jay Gould was wrong. It should never have happened.

At 1300 pages plus, Gould's book is a challenging read but he writes so well and so engagingly that the pages almost turn themselves. This is the clearest and best book I have ever read on evolution. Witty, detailed, argumentative, and arrogant (in a professorial and good way). A bargain for the price.

I've been living with this book for a few weeks now. It's big, so it is the sort of book that becomes part of your life for a while if you stick with it, like a piece of furniture (it's certainly big enough to be one).Anyhow, wanted to report back on a few things: First, on the writing--there are places where TSET needed a stronger editor, most particluarly at the beginning when Gould runs through his philosphical and categorical underpinnings. Here he's rather unnecessarily Germanic, I'd say. And there are times over course of the book where Gould drifts back into this mode: very long, complex sentences that could have easily been pared back in the service of both clarity and readability.But these are exceptions over the course of a 1400-page book: for the most part Gould gives us his usual engaging, clear, sometimes colorful prose.Another reviewer remarked the fact that sociobiology wasn't in the index. Niether is evolutionary psychology, but both of these things are talked about, both directly and indirectly. It isn't that Gould is playing "selective history" so much as that the Index is woefully inadequate for a work of this size and complexity.Complex? Well, aside from the technical nature of much of the book, there is also a fair amount of organizational drift at the micro level. At the macro level the book is pretty effectively divided into logical sections, but within sections Gould tends to digress and return to pages-back points quite a bit. And a lot of the book is NOT really systematically presented. Rather Gould has a few assays (or essays) at a topic from different angles of attack. There is definitely a recognizable "view of life" behind these different sections, and the method works pretty well, really, as exposition, but . . . this sort of discursive style makes a good index an absolute necessity.There's one chapter that has come in for a bit of criticism, a defense of Gould's theroy of Punctuated Equilibrium with asides on personal jealousy and other things driving his critics.Self-serving? Yes! But interesting and enlightening, as well, putting the ball pretty solidly in the court of Gould critics.There are garcious moments as well: his treatment of Dawkins's Selfish Gene theory is generally pretty open-minded, as is his parting exhortation to the budding field of evolutionary psychology.If you are interested in this field, this is a book you ought to peruse extensively.

Gould's masterwork and the authoritative summation of 20th Century evolutionary biology. Unfortunately, Gould died of cancer before it could be edited. The result is a meticulous description, defense and extension of Darwinian evolutionary theory that is unfortunately filled with excess verbiage relating to Gould's ego and irrelevant interests such as baseball and religious architecture, and too much pedantic history that I think contribute nothing to the fundamental arguments.I first met Gould in the Evoluitionary Biology course that Ernst Mayr and he taught at Harvard University, in the late 1960's. I was very put off by Gould's constant wordiness and self-promotion. Over the years I read several of his books, with the only one to impress me being his [A Wonderful Life] on the early Cambrian Burgess Shale fossils. Thus, I began reading "The Structure of Evolutionary Theory" with a lot of prejudice, that was reenforced by the plethora of Gould's annoying writing habits and mannerisms that make the book much harder going than it should have been. However, on perserving, my conclusion is that the work stands as the outstanding masterwork encompassing the development of evolutionary theory from before Darwin through the end of the 20th Century. Anyone who claims to be an evolutionist should have and read this book, bearing in mind that Gould was already sick before it was all written, and that there was simply no time for the rigorous editing that could have turned the masterwork into a book that should also be a best-seller.

I'm only 100 pages in -- somewhere in the chapter where he presents essay-length outlines of each of the remaining chapters.This is undoubtedly a truly important work, not to mention monumental (in every sense of the word). So what if Gould's publisher could not afford him an editor ;-)I look forward to finishing this -- will report back.(john)

With 'The Structure of Evolutionary Theory' (SoET), The late Stephen J. Gould offers readers a comprehensive revision of Darwinian thought. His revision disagrees with the current orthodoxy, known as the Modern Synthesis, though adherents of each view call themselves Darwinists. In SoET, Gould identifies three defining features of Natural Selection: agency, efficiency, and scope. To survive the revision, Darwinism¿s tripod (Gould's image) must keep all of its three legs; amputation of any one would topple the whole structure. By agency, orthodox Darwinism argues for evolution happening exclusively at the organismic level. Ultimately it is individuals who survive and breed, or die. It is this or that particular being who will outlive its siblings long enough to have children. Groups, species, and populations, for Darwinism, don't do anything. By efficiency, Darwinism argues that from many random variations, only those variations that help the organism do something better (see more clearly, run faster, etc.) will be transmitted. Features appear because they are useful to the organism, because they have a function that contributes to the living being¿s survival and progeny. By scope, Darwinism argues that Natural Selection operating on individual organisms can explain the entire history of life on earth, and that no further process needs to be introduced into the theory. Natural Selection would be a complete theory. Having presented the image of the tripod, Gould continues with an exegesis of Darwin's Origin of Species. The first part of the book develops a history of evolutionary thought, presenting and rehabilitating many discredited formalist thinkers, such Geoffroy St-Hilaire and Hugo DeVries. The first part ends with a description of the Modern Synthesis (current orthodoxy). Then, in the second part, we are given a revised evolutionary theory, much of which was in fact developed by Gould and his colleagues Niles Eldredge and Elisabeth Vrba (to both of whom the book is dedicated). The book describes Gould¿s and Eldredge¿s own theory of Punctuated Equilibrium (PE): that often and in most cases (though not all) in between long stretches of nothing-happening (equilibrium, or stasis) evolution happens quickly (punctuation). Gould also presents the concept of constraints as positive forces, and shows them as channels of direction aiding flow. He contrasts this positive interpretation with the usual negative one of constraints restricting movement. Gould uses this with his earlier rehabilitation of formalist thinkers, to present historical and structural constraints as creative forces of evolution that operate independently from Natural Selection (i.e. orthogonally or sideways rather than with or against). Throughout the second part, Gould revises each leg of the tripod. Following Gould, Natural Selection does not explain all of history (the scope leg) e.g. it fails to explain lineages that don¿t change. Immediate usefulness (the functional leg) is only one of the forces at work; constraints in particular work independently to, the functional drive; 3) evolution occurs at many levels (the agency leg): at the gene, cell, organisms, species, and clade levels. Throughout the book Gould also emphasizes two concepts. The first is Relative Frequency and the second is the distinction between Historical Cause and Current Use. Neither of these concepts belongs to Gould, nor does he claim them, and Darwin himself was intimately familiar with them. Gould champions these ideas because he feels even experts aren¿t paying them enough attention. First, by relative frequency Gould means determining how often different processes occur throughout the history of life. For instance, Gould accepts that species often evolve gradually (classical Natural Selection) but he does insist that much of the time speciation happens quickly following long periods of no change (Punctuated Equilibrium) and even suspects that th

Sadly, Stephen Jay Gould died only two months after his 1433 pages book The Structure of Evolutionary Theory (henceforth, TSET) was published. Surprisingly, TSET is NOT about the structure of evolutionary theory, and it is NOT a portrayal of the current state of evolutionary theory. Instead it is about The Structure of Gould¿s Evolutionary Theory. So even the title of this book is confused. (Below I will show that the content of the book is extremely confused.) Gould claims TSET to be part of a Hegelian dialectic, in which Darwinism has become the thesis, with ¿Gouldism¿ (my word) as antithesis, and, of course, a synthesis waiting to be born in the future. Obviously, Gould is Darwin II. Like Marx¿s Das Kapital, the TSET does not end. And, like Marx, Gould uses ¿outpouring, masquerading as a single sentence.¿ One searches in vain for a clearly expressed sentence. Several Gouldisms are impossible to understand. An example: ¿autapomorphy¿. And, like Marx, he does rely too heavily upon rhetoric. In TSET Gould picks his history: ¿Sociobiology¿ doesn¿t appear in the index. The revolutionary theory of ¿Evolutionary psychology¿ emerges briefly. Robert Trivers is ignored although reciprocal altruism is mentioned (unattributed). William D. Hamilton is largely ignored. E. O. Wilson is ignored. No Haeckel. No Spencer. No Mayr. No Dobzhansky. No Simpson. No ¿ Selective argumentation characterizes most of TSET. An example: Richard Dawkins devastingly critical analogy for the gradualist-punctuationalist debate is unmentioned. Unbelievable but true: Gould claims that it is impossible to speak meaningfully about the effect of a single gene. But, undoubtedly, Mendel did speak meaningfully about the effect of a single gene. Moreover: No matter how complex the interactions, the substitution of one allele for another must have a mean arithmetic effect on fitness. In turn fitness will convey differential evolutionary advantage upon different alleles. Again, Gould is absolutely wrong. Punctuated equilibrium isn¿t the revolutionary approach that Gould claims. Obviously, there have been periods of relative ¿stasis¿ (stasis = no evolutionary change) punctuated by relatively rapid changes, because environments change irregularly and unevenly. However, even rapid evolutionary change involved tens of thousands or hundreds of thousands of years and when they occurred, ordinary natural selection was responsible! Gradualism does not deny that catastrophes sometimes happen. But after catastrophes, ordinary natural selection takes up where it left off. Clearly, the ¿theory of punctuated equilibria¿ is not a scientific revolution. 'Gould has been pushing against an open door', says David P. Barash. Gould falsely claims that the ¿subject of stasis had never been subjected to quantitative empirical study ¿¿ In fact, there had been numerous quantitative studies of evolutionary stasis in many taxa. Gould claims that selection does not at all occur at the gene level! He even speaks of gene selection in the past tense, as though it has been disproved! How can genes NOT be a unit of selection? In fact, genes are THE unit of selection. Richard Dawkins, Robert Trivers, William D. Hamilton, and George C. Williams emphasize selection at the gene level, because genes, unlike individuals, groups, and species, are persistent ¿replicators¿, which selection can maintain, promote, or extinguish over time. But, of course, even arch-reductionists acknowledge that selection operates at many different levels simultaneously. Again, it is much ado about nothing. We all know that natural selection is not the only mechanism of genetic change, but undoubtedly it¿s by far the most important mechanism. But Gould makes it appear as though natural selection has been dethroned! And the path-breaking works of John Endler and numerous other scientists about natural selection are totally ignored! Gould argues that evolution has almost nothing to do with human behavior. 'Go

I did go down to the local Barnes and Noble bookstore and look through Gould's last book written before he passed on, The Structure of Evolutionary Theory, which they call his 'magnum opus'. I would indeed agree with that assessment since spending part of a day there flipping though it and reviewing it. It is the largest literary tome that I have ever come across that in essence says absolutely nothing about anything, filled with minutae and garbled arguments on the topic of whether organisms evolve or species evolve (sadly, I believe that at the point when he wrote this, his mind must have verged on the border of delusion or early senility, the entire wording and vague pronouncements that he makes on such an obtuse and essentially non-definable irrelevant subject are indications that he was beginning to get lost in the fog of his own nebulous Darwinian dogma) or how any other types of species arrived here either. The only other book that I can equate it to would be The Urantia Book, a huge bestseller back in the seventies with the UFO crowd that appealed to a host of strange alien abduction/reincarnation/newage cults who thought that we were being guided in our socio/historical progress by unseen alien beings. Goulds work is a monumental tribute to man's stubborn insistence to refute such plain, unequivocal evidence placed here before our very eyes-the remarkable evidence for Intelligent design and the glaringly obvious separate and distinct Kingdom, Phylum, Class, Order, Family, Genus, and Species classifications of organisms that to this day give credence to Linnaeus' classical theistic viewpoint of the origin of life.
