LettersContinued from page 7The Author RepliesIn his haste to defend Sir CharlesDarwin, Dr. Bonner has neglected theexperimental evidence of Drs. Bush,Wilson, Levin et al. which was themain scientific substance of my article.This oversight conveniently allowsDr. Bonner to ignore the point of myarticle, "Evolution: A Riemannian Approachto Biology." However, I willnot let him dodge the scientific evidenceor its epistemological andmoral implications.In studies involving more than10,000 species, Drs. Bush, Wilson,Levin et al. have demonstrated thatrandom point mutations cannot accountfor the relatively rapid rate ofevolution of placental mammals. Ofall the inherited features studied, onlychromosomal changes correlate withthat evolution, and these changes areassociated with changing global bioenergeticrelationships.The traditional tenets of Darwinianbiology, fully elaborated by moleculargenetics, are thereby disproven. Thearticle's point is to explain why thatshould be so, and to propose an alternative.Dr. Bonner, you have prowledaround the outside of this discussion,sniffing something that, perhaps,frightens you. Hurling epithets in itsdirection ("incompetent," "uninformed,""stupid argument"), youscamper off in the other discrediteddirection. Why not face the evidence,probe to the core of the argument,and rethink your area of expertisefrom the standpoint of a more advancedhypothesis?The evidence establishes thatchanging chromosomal structures occurredat a rate that could uniquelyaccount for the rate of evolution inthe historic record of placental mammals.This, of course, is a matter ofcorrelation. What remains open is thecausal question. If chromosomalchange accompanies speciation, underwhat circumstances, and how?There is really no point in referringto T. Dobzhansky's experiments onpseudo-obscura fruit fliesj Admittedly,he managed to produce all sortsof chromosomal changes that did notresult in ^peciation. But then, evolutioncould not have occurred underthe constrained conditions of Dobzhansky'slaboratory.A Riemannian ApproachI usedj the phrase Riemannian approachfpr this reason: Evolution isnot "ran|dom point mutation" of aChromosomes: The chromosomesfrom a human cancer victim, showingpronounced structural aberrations.particular member of a species, but anexus cf the most rapidly evolvingspecies currently transforming thebiosphere. This internally differentiatingnexus, or singularity, is sociallyorganized such that general increasesin biological <strong>energy</strong> throughput arenonlinekrly amplified and channeledinto the progeny of those species.Such progeny, born within this geometryof biological <strong>energy</strong> surplus,then generate still further advances inthe biochemical and technologicalcapacity of the singularity to transformthe biosphere even more rapidly.Thus, evolution is the path of thebiosphere from lower to higher ratesof overall <strong>energy</strong> throughput via speciation.What evolves is the characteristicmode £>f capture of solar <strong>energy</strong> bylife forms whose "living" nature is toemployj inorganic "resources" to convertsolar <strong>energy</strong> into biological material.The mammalian-angiosperm"warm blooded" complete, for example,cqnstituted a new "technology"of the biosphere, altogether redefininginorganic "resources" for life onearth. Compared to reptilian forms,they had significantly greater populationpotentials, greater differentiationpotentials, higher rates of solar<strong>energy</strong> conversion by biological processes,and a capacity for sustainedincreases in overall biological <strong>energy</strong>throughput by further developmentin this way. By the time of the UpperOligocene, the mammalian-angiospermforms were, quite literally,"making deserts bloom."No theory of "natural selection" isrequired or possible. "Survival of thefittest" and "scarce resources" are thedriving force of decay. Abundant andgrowing "free <strong>energy</strong>" is the drivingforce of evolution. By the Upper Oligocene,for instance, a certain arrayof angiosperms began to speciate intothe forms called grass and spread withrapidly speciating ungulates into thedeserts of continental interiors, transformingnet "reflectors" of solar <strong>energy</strong>into concentrations of biomass10 times the density of the deciduousforest. Evolving mammalian-angiospermforms did not adapt to an environment,but evolved to create theirown, ever more <strong>energy</strong>-dense biosphere.NegentropyEvolution is not random, butcausally negentropic.In light of the evidence presentedin molecular biology by Bush et al.,the substance of my article addressedthe proposal that highly orderedchromosomal geometries mirror increasedrates of biological <strong>energy</strong>throughput in a species positively interactingwith an increasingly differentiated,<strong>energy</strong>-dense biosphere. .My hypothesis was that the mostrapidly evolving species of placentalmammals were socially organized,such that general increases in biological<strong>energy</strong> throughput were concentrated,amplified in a nonlinear fashion;and channeled via chromosomalreordering into the progeny of thespecies. In sum: speciation means relativelyrapid increases in biological<strong>energy</strong> throughput, sustained and, asit were, "institutionalized" in chromosomalchange.The case of flax is one of inherited8 FUSIONSeptember 1980
change accompanied by an at leasttemporary increase of DNA per cell,implying a significant change in globalchromosome geometry in flax nuclei—achievedby increased biological<strong>energy</strong> throughput under optimalgrowing conditions. This is contrastedwith cancer—inherited geneticchange by entropic changes in biological<strong>energy</strong> throughput—and withthe necrotic cell, in which suddencollapse in <strong>energy</strong> throughputchanges cell geometry dramaticallytoward quasi-crystalline structureslike those found in inorganic chemistry.Biological "space" is a geometrycorresponding to a higher <strong>energy</strong>flow than that of the inorganic realmat comparable temperatures. Thehighly ordered, highly differentiatedgeometries of eukaryotic nuclei aresusceptible to both entropic and negentropicchange based on biological<strong>energy</strong> throughput. The flax case, infact, corresponds to the "singularities"through which the biosphereevolved in the Cenozoic: chromosomalchange under conditions of increasingbiological <strong>energy</strong> throughputand higher states of organizationresulting (uniquely) in speciation.Dobzhansky Vs. CausalityIt is most useful that Dr. Bonnerraises the issue of Theodosius Dobzhansky,his mentor. Dobzhanskytrained under circles at Kiev associatedwith the Societas Jesu; in 1969,he was president of the Teilhard deChardin Association, of which he wasa member of long standing; and he isthe exemplar in molecular biology ofthat apparently contradictory combinationof Jesuit empiricism and mysticismthat logically ensues from thesubstitution of statistical correlationfor causality in science.In contrast, the Neoplatonic traditionlocates the emergence of man inhis unique powers of Reason. Conspiraciesof Reason have generatedthe Renaissances that have repeatedlytransformed the biosphere itself byqualitative leaps in the pace of humanscientific and technological activity.These leaps lift the human speciesfrom the burden of beastlike pursuitof sustenance to its highest creativepotential. This, in turn, becomes theprimary force for continued evolutionof the lower-order inorganic and organicdomains.This is certainly not the worldviewof Malthus, nor the pseudoevolutionistsDarwin and Dobzhansky. As oneof this century's most respected expertson genetics and "evolution," ashe terms it, Dobzhansky conductedexperiments in an "equilibrium" fishbowl,effecting genetic mutations ontotally inbred laboratory Drosophila,without a thought for the actual historicprocesses of evolution and theircauses. With causality stripped out,the evolutionary process is renderedinexplicable and man is relegated tobestialism and the supernatural."To many, Darwin seemed to havedelivered the heaviest blow, makingthe schism in man's soul irreparable:Flax: Fourth-generation flax plantsderived from a single set of parents,showing nonmutational heritablechanges that refute current neo-Darwiniandogma.far from the world having been madefor man, man himself proved to bemerely one of some two million biologicalspecies . . . and a relative ofcreatures as disreputable as monkeysand apes," wrote Dobzhansky in hisoft-quoted Mankind Evolving.There is, however, "a source ofhope in the abyss of despair." Dobzhanskycontinued: "Teilhard deChardin saw that evolution of matter,the evolution of life, and the evolutionof man are integral parts of asingle process of cosmic development.... He chose to designate thedirection in which evolution is goingas 'The Point Omega' ... 'a harmonizedcollectivity of consciousness'... a kind of superconsciousness. . . .The plurality of individual thoughtscombine and mutually reinforce eachother in a single act of unanimousThought. ... In the dimension ofthought, as in that of Time and Space,can the Universe reach consummationin anything but the Measureless?. . . This is nothing less than afundamental vision. And I shall leaveit at that."But Dobzhansky did not leave itquite at that—an "equilibrium" worldwhere all evolution ends and man justmeditates with Teilhard and,the restof the Aquarians. For example, hewrote:"Despite having been temporarilyperverted by racists, the eugenicalidea has a sound core: human welfare,both with individuals and withsocieties, is predicated upon thehealth of the genetic endowment ofhuman populations," Dobzhanskywrote in the same source. "Osborn(1951) has rightly said that 'eugenicsis not in opposition to efforts to improvethe environment, but in manycases a necessary supplement to theirsuccess.'"Quite predictably, the outcome ofDobzhansky's Darwinian method iseugenics, dividing the world into the"fit" and the "unfit." Do not mistakemy meaning. We must pursue allpromising avenues of genetic and recombinantDNA research to achieveall the obvious benefits in medicaland agricultural practice. But we mustalso have the larger theoretical basisfor making the fundamental researchbreakthroughs we need to cure cancer,to develop more productive agriculture—inshort, to make possiblenew leaps forward for future generations.Dobzhansky's Darwinian geneticslead only to the depopulationschemes of the Malthusians.Is this really what you want, Dr.Bonner?Carol ClearySeptember 1980 FUSION 9
