To illustrate, a chess master can usually recall the positions of all the pieces on a chessboard after a quick glance. But if the chessmen are arranged randomly and meaninglessly, his memory is reduced to near-normal. The gist is that long prac-tice and the application of mnemonic devices can vastly improve anyone's memory and, in consequence, memory prodigies are not really so anomalous. (Ericsson, K. Anders, and Chase, William G.; "Exceptional Memory," American Scientist, 70:607, 1982.) Comment. The real anomaly here may be the fact that the human memory and related memory faculties seem orders of magnitude better than needed for survival. How did such capabilities evolve? Of what use is a prodigious memory to an Ice Age man facing a cave bear? Are we dealing with prescient evolution, like the moth described above, holding capabilities in reserve until they are really needed. From Science Frontiers #26, MAR-APR 1983 . 1983-2000 William R.

Few scientists have contemplated the possibility of life forms prospering at temperatures well beyond 100 . Recently, however, the discovery of many new and frequently bizarre organisms clustered around deep-sea vents has forced a reexamination of high-temperature life. It seems that bacteria actually flourish in the 350 C water streams from the deep-sea vents. In the lab, these same bacteria multiply rapidly in water at 250 C kept liquid by pressures of 265 atmospheres of pressure. What a surprise! Quoting a concluding sentence from this article: "This greatly increases the number of environments and conditions both on Earth and elsewhere in the Universe where life can exist."

... digs asserted to be older than 12,000 years), do not imagine that all archeologists embrace these claims. For example, a recent issue of Discovering Archeology debunked them at great length and rather testily to boot. This broadside was followed by a devastating review of T.D . Dillehay's The Settlement of the Americas: A New Prehistory in the magazine Natural History. The reviewer for Natural History, A.C . Roosevelt, a respected anthropologist at the University of Illinois, targets the Cactus Hill site, in Virginia (SF#130). This dig, she says, is characterized by "inconsistent dates, vague stratigraphy, and inadequate artifact samples that disqualify them from scientific acceptance." Even Dillehay's monumental work at Monte Verde, Chile, does not survive the review unscathed. In fact, the claimed pre-Clovis sites, according to Roosevelt, do not yield sound, consistent radiocarbon dates earlier than 11,500 B.P . She will, however, entertain Bering Strait crossings as early as 12,000 B.P ., but not a microsecond earlier. (Roosevelt, Anna Curtenius; "Who's on First?" Natural History, 109:76, July-August 2000.)

... long. It is a confusing canvas to say the least. This gigantic terrestrial easel covers 400 square miles. Upon it are drawn more than 1,000 biomorphs and geoglyphs, plus some 800 straight lines. It is one of the world's great archeological legacies from the deep past. Actually, at least two canvasses seem to be superimposed. The earliest canvas consists of the geoglyphs, which were incised beginning about 200 B.C . Peel away these, and we are left with the geometrical figures and straight lines. These seem to have been inscribed starting about 600 A.D . -- a time of severe drought, which may be a clue to their purpose. Next, strip off the geoglyphs (trapezoids and such), and a seeming mishmash of straight lines survives. But most are not random when analyzed. Most converge spoke-like upon 62 or more "ray centers." Thus, the Nazca Plain seems to be a 3-page book: biomorphs, geoglyphs, and spoked ray-centers. They all overlap. It's all a gigantic Rorschach test; and different observers see different things! A Nazca biomorph (monkey with spiral tail) overlain by an abstract, unexplained geoglyph. See Book Supplement for still another Nazca figure. Of course, there are doodles on this 400-square-mile canvas that don't fit on any of the three pages. We'll have to ignore them for now.

What we often ignore is the fact that forces and energies almost beyond our comprehension course through the cosmos. Even the Starship Enterprise could not really survive out there. Three cautionary tidits will illustrate the hazards as well as our ignorance of them. "What could possibly accelerate a single subatomic particle to such a high speed, 99.99999999999999999999 percent that of light, that it would smash into the earth's atmosphere with the energy of a hard-hit tennis ball?

... have just lost their wives have lowered white-cell responses. Although many physicians and medical researchers think it too early to claim that mental stress significantly suppresses the human immunological system and thus leads to more illness, one can see the pendulum start to swing away from the timehonored belief that mind and body are entirely separate entities. The foregoing studies and others like them are discussed in a recent survey of psychoimmunology by B. Dixon. Toward the close of the article, Dixon asks why humans (and other animals, too) have evolved an immunological system sensitive to stress. Evolutionists can always find some sort of justification in Darwinian terms, and Dixon's is rather ingenious. Suppose a primitive human was attacked by a saber-toothed tiger (what else?). If the human survived, his immunological system would immediately go into high gear to clean up the wounds and repel invading germs. The trouble is that a revved-up immunological system (especially the white blood cells) can go too far and chomp up healthy tissue, too. However, evolution has constructed animals such that stress (saber-toothed tigers are stressful!) suppresses the immunological system to restrict the consumption of healthy tissues. While this short-term damper on immunological activity may have been useful to primitive humans, the stresses on modern man are less intense and long-term. We are sick a lot, particularly with cancer, because evolution has not yet adjusted or finetuned us to the new environment. (Dixon, Bernard; "Dangerous Thoughts," Science 86, 7:63 ...

... there. They bring their article to a close with an almost poetic manifesto that we now quote in part. The context of the quotation is their assertion that plant and animal evolution would never have taken place unless one life form attacked another and the latter defended itself, all this followed by accomodation and the development of a symbiotic relationship. "Uneasy alliances are at the core of our very many different beings. Individuality, independence -- these are illusions. We live on a flowing pointillist landscape where each dot of paint is also alive. Earth itself is a living habitat, a merger of organisms that have come together, forming new emergent organisms, entirely new kinds of 'individuals' such as green hydras and luminous fish. Without a a life-support system none of us can survive. It is in this light that we are beginning to see the biosphere not only as a continual struggle favoring the most vicious organism but also as an endliess dance of diversifying life forms, where partners triumph." (Sagan, Dorion, and Margulis, Lynn; "Bacterial Bedfellows," Natural History, 96:26, March 1987.) Comment. One should observe that there is a strong connection between the Gaia concept of a living planet and the theory of symbiotic evolution. Strong philosophical statements are also inherent in this outlook on life and its development. For example, individuality and free will would seem to be denied. Also, can life forms be "vicious" and yet "cooperative" at the same time? From Science Frontiers #51, MAY-JUN ...

Several findings suggest that lefthandedness may be associated with reduced longevity. For instance, Porac and Coren reported that 13 per cent of 20-year-olds are lefthanded but only 5 per cent of those in their fifties and virtually nobody of 80 or above. We believe that this absence of left-handers from the oldest age groups reflects higher biological and environmental risk." To investigate this asymmetry further, D.F . Halpern and S. Coren repaired to The Baseball Encyclopedia , where longevity and handedness are duly recorded for many players. Here again, they found that, although mortality is about the same up to age 33, thereafter about 2% more right-handers than lefthanders survive at each age. Halpern and Coren suggest a few possible causes: (1 ) prenatal and perinatal birth stressors are more probable in left-handers; (2 ) the immune systems of lefthanders may be reduced by ge netic effects and intra-uterine hormones; and (3 ) left-handers may suffer more accidents in a world designed for righthanders!

... out. This would have broad implications. For example, directed mutation would shatter the belief that organisms are related to some ancestor if they share traits. Instead, they may simply share exposure to the same environmental cues. Also, different organisms may have different mutation rates based on their ability to respond to the environment. And the discipline of molecular taxonomy, where an organism's position on the evolutionary tree is fixed by comparing its genome to those of others, would need extreme revision." What sort of experiment did Cairns do to cause such a ruckus? In particular, he studied E. Coli bacteria. Normally, these bacteria cannot metabolize the sugar lactose. Cairns exposed the E. Coli to a sudden dose of lactose, demonstrating that if the bacteria must have lactose to survive, they quickly cast off the two genes that inhibit their metabolizing of lactose. Of course, the experiments were more complicated than this, but the fundamental finding was that the bacteria mutated so that they could use lactose much, much faster than chance mutation would permit, stastically speaking. The battle lines are forming. A sup-porter of directed mutation, J. Shapiro, of the University of Chicago, is quoted as follows in Moffat's article: "The genome is smart. It can respond to selective conditions. The signifi cance of the Cairns paper is not in the presentation of new data but in the framing of the questions and in changing the psychology of the situation. He has taken the question 'Are mutations directed?' which was taboo, and made ...

... University of Adelaide, Australia, described a newly discovered frog species that broods its young in its stomach. The frog was once so commo 'an agile collector could have picked up 100 in a single night,' Tyler says. By 1980 it had completely disappeared from its habitat (a 100-square-kilometer area in the Conondale Ranges, 100 miles north of Brisbane). It has not been seen since." Similar stories emanate from Brazil, Japan, Mexico, Norway, and elsewhere. Many environmental causes have been proposed, but it is significant that the frogs are also disappearing from nature preserves where environmental pressures are small. D. Wake, a biologist at Berkeley, has remarked: "[ Amphibians] were here when the dinosaurs were here, and [they] survived the age of mammals. If they're checking out now, I think it is significant." In this context, Wake believes that there is a single, global, still-unidentified cause operating. (Barinaga, Marcia; "Where Have All the Froggies Gone?" Science, 247:1033, 1990.

... to the pulse jet propulsion mechanism of the German V-1 'buzz' bomb of World War II." What the beetle has "evolved" is an intermittent explosive process that fires about 500 pulses per second. The explosive energy comes from the mixing of two separate fluids (hydroquinones and hydrogen peroxide with oxidative enzymes). (Dean, Jeffrey, et al; "Defensive Spray of the Bombardier Beetle: A Biological Pulse Jet," Science, 248:1219, 1990.) Comment. The fundamental question is, of course, how can many, small, random mutations contribute to the development of the mechanisms of the pulse jet, its two fuels, the pumps, the fuel reservoirs, the control system, etc., when only the complete, perfected system has survival value. Although creationists argue that the theories of evolution and natural section are unconvincing here; it is still possible that atheistic factors still beyond our ken are operating, and that what we really need is a better theory of evolution.

... into gene structure is anyone's guess. (In fact, since the DNA in the genes seems to cody only for protein synthesis, the locations and characters of inheritable maps and other biological instructions are not immediately obvious.) The problem has been exacerbated by recent experiments with German and Austrian blackcaps. These two common European warbler species take different routes to Africa in the winter. The Ger-man blackcaps fly southwest and the Austrian southeast--routes 50 apart. A. Helbig has crossed the German and Austrian blackcaps to see what route(s ) their hybrid offspring would take. Curiously, they favored a route intermediate between those of their parents. The hybrids' route -- bisecting those of the parents' -- would take the hybrids right into the Alps, where survival would be unlikely. (Day, Stephen; "Migrating Birds Use Genetic Maps to Navigate," New Scientist, p. 21, April 21, 1991.) Comment. The puzzle at hand concerns those purported genetic maps. Presumably, the hybridization of the two blackcaps involves the melding to two different, highly specific, maps and sets of migration instructions; possibly including compass directions (astronomically or magnetically determined), landmark locations, and even characteristic pathway odors. How can such instructions be combined (perhaps averaged) to draw up entirely new navigation instructions for a route the parents have never taken?

... life styles have changed drastically; for example, some Polynesians, American Indians, and Australian aborigines are similarly afflicted. Furthermore, an epi-demic of diabetes mellitus is anticipated as the "benefits" of civilization are brought to India and China. Two questions must be answered: (1 ) Why is the incidence of diabetes mellitus only 8% among American junkfood-eating couch potatoes? Probable answer: natural selection has already modified the American genotype by eliminating those who are supersensitive to diabetes mellitus under conditions of rich diets and sedentary lives. (2 ) Why are modern populations still living under Spartan conditions so sensitive to diabetes in the first place? Possible answer: the so-called "thrifty genotype" hypothesis. In this view, the genotype that is sensitive to diabetes also confers survival advantages in societes where food supplies are meager and unpredictable. This genotype provides for a hair-trigger release of insulin for the rapid conversion of rare food gluts into body fat deposits that will sustain the individual during the next famine. Unfortunately, when rich food is continuously available, people with this "hairtrigger" genotype succumb to diabetes. (Diamond, Jared M.; "Diabetes Running Wild," Nature, 357:362, 1992.)

... to New Scientist, J. Margolis commences with the observation that calculating prodigies (idiot savants), who are often also mentally retarded, can easily and almost instantaneously recognize 20-digit prime numbers! Gifted mathematicians with so-called photographic memories cannot perform such mental feats using known methods for identifying primes. What do the calculating prodigies know that the rest of us do not? Better algorithms; that is, calculating methods? Margolis expands on this: "All this suggests some relatively simple, subconscious algorithms which have not, as yet, been explicitly formulated. Research in this direction might well result in new mathematical insights. "It need not be surprising that mathematical insight is more fundamental than language. Even a primitive animal brain is 'wired" to perform exceedingly complex computations essential for survival in an unpredictable environment. The latest 'smart' weapons are rudimentary compared with a humble gnat. Mathematics could be a by-product of these functions. Language is a comparatively recent evolutionary innovation and it is quite possible that conscious manipulation of abstract symbols has not caught up with an innate ability to perceive quantitative relationships."

... of meteorites. A logical question is: Can life forms and/or chemical precursors of life be transported thus across the far reaches of the solar system? Can one planet infect another ballistically? An analysis by M.K . Wallis and N.C . Wickramasinghe is rather warm towards this idea: "The mass of escaping ejecta from the presumed 10-km comet that caused the 180-km Chicxulub crater, with a radius of roughly 10 km and 1 m deep, amounted to ~300 Mm3 , of which one third may have been rock and 10% higher-speed ejecta that could have transited directly to Mars. It may have taken 10 Ma to impact Mars but...the probability is not exceedingly low but 0.1 -1 %. "The survival and replication of microorganisms once they are released at destination would depend on the local conditions that prevail. Although viability on the present-day Martian surface is problematical, Earth-to-Mars transfers of life were feasible during an earlier 'wet' phase of the planet, prior to 3.5 Ga ago. The Martian atmosphere was also denser at that epoch, with several bars of CO2 , thus serving to decelerate meteorites, as on the present-day Earth. Since the reverse transfer can occur in a similar manner, early life evolution of the two planets may well have been linked."

Science Frontiers ONLINE No. 107: Sep-Oct 1996 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Rock-Based Life Virtually all biology textbooks insist that all terrestrial life ultimately depends upon sunlight for its survival. The ecosystems clustered around the deep-sea vents and the bacteria found in deep aquifers demonstrate that the sun is not essential to life -- chemical energy does just fine. In fact, the domain of chemosynthetic life has now been extended to a Romanian cave that has apparently been almost completely sealed off from surface influences for 5.5 million years. Air does leak in through tiny cracks, and water partially fills the cave. What is most remarkable in this sunless, sealed ecosystem is its biodiversity: 48 animal species, including 33 brand-new species. The roster includes isopods, a millipede, a centipede, a water scorpion, and a leech. Of course, bacteria and fungi thrive there, too. In contrast to unsealed caves, where insects, bats, and other sources of food filter in from the surface, life in the Romanian cave seems to derive entirely from hydrogen sulfide present in the cave's rocks. This compound is consumed by microorganisms, which are then grazed by cave occupants higher up the food chain. A NASA scientist has called Movile cave a "Mars analog site." And indeed it might be, for Mars has plenty of rocks and subsurface water. (Skinrud, E.; "Romanian Cave Contains Novel Ecosystem," Science News, 149: 405, ...

... isolated rocky islands, each with its own unique complement of cichlid fish; each island has species found nowhere else in the lake. Where did all these species come from, considering that their little islands were bone dry just a century ago? Goldschmidt writes: "Cichlids that inhabited these exposed rocks would have suffocated, unless they had already left for wetter climes. Yet today, species that do not exist anywhere else can be found near almost every rocky island. From an orthodox point of view, the most plausible explanation for this is quite surprising: many color forms as well as biological species developed over a period of less than two hundred years." This is certainly explosive speciation -- real biological punctuation! But, perhaps as water levels fell, the original cichlids found refuges in surviving pools and then repopulated the lake when the waters rose. But is it reasonable to believe that they all sorted themselves out so perfectly that many species are found nowhere else in the lake? The probability seems high that cichlid speciation has been very rapid -- too rapid, one would think for random mutation and the slow feedback of natural selection to accomplish this daunting task in just a century or two. Might there not be some additional nonsupernatural factor at work? (Goldschmidt, Tijs; Darwin's Dreampond , Cambridge, 1996, p. 125.) From Science Frontiers #110, MAR-APR 1997 . 1997-2000 William R.

You'll recall that cannibals thought to acquire the virtues of their slain enemies by grabbing a bite or two! But this all sounds pretty farfetched, doesn't it? Maybe not. When W. Doerfler and R. Schubbert, at the University of Cologne, fed the bacterial virus M13 to a mouse, snippets of the M13's genes turned up in cells taken from the mouse's intestines, spleen, liver, and white blood cells. Most of the alien DNA was eventually rejected, but some was probably retained. In any event, alien DNA in food seems to make its way to and survive for a time in the cells of the eater. (Cohen, Philip; "Can DNA in Food Find Its Way into Cells?" New Scientist, p. 14, January 4, 1997.) Comment. We are only half-kidding when we ask if food consumption could affect the evolution of a species. After all, our cells already harbor mitochondria, which are generally admitted to have originally been free bacteria that were "consumed" by animal cells.

Yet, motion sickness occurs in many species. Why should it have evolved at all? Recognizing this problem, Michel Treisman seeks to explain the anomaly by noting that neurotoxins accidently ingested by animals cause essentially the same symptoms as motion sickness. To survive, animals must eliminate ingested neurotoxins by vomiting or defecation, both of which also accompany motion sickness. It is simply coincidental that modern vehicles duplicate these symptoms through their motions. The body interprets the signals created by motion as due to dangerous ingested material and acts accordingly.

Over 300 serious discrepancies are tabulated and backed by some 445 references from the scientific literature. To remove triviali-ties, only dates that were "wrong" by 20% or more were included. This criterion insured that the anomalous dates were off by one or more geological periods. To enhance his case, Woodmorappe excluded data for such troublesome minerals as K-feldspar, which have unreliable records. The surviving discordances will certainly disturb anyone who has long accepted radioactive dating as the near-final word in geochronology. The lengthy text accompanying the table delves into the geological problems posed by the tabulated anomalies, primarily the severe distortions implied in the supposedly well-established geological time scale. Many attempts have been made to explain away these discrepancies, usually by asserting that the system must have been "open"; that is, contamination and/or removal of materials occurred. But a far more serious situation exists: the reluctance of researchers to publish radiometric dates that fly in the face of expectations. Data selection and rejection are epidemic. Some authors admit tossing out wild points; others say nothing. (Woodmorappe, John; "Radiometric Geochronology Reappraised," Creation Research Society Quarterly, 16:102, 1979.)
