Any New World dates earlier than 12,000 BP, maybe 20,000 BP for a few daring souls, have to be erroneous. How are the Pedra Furada chipped stones explained by mainstream archeologists? They are "geofacts, not artifacts. They were created when quartzite rocks were released by erosion and fell off cliffs to be smashed upon impact below. Gravity and not the human hand broke the quartz into pieces that just happen to look like prehistoric tools. F. Parenti, a coworker of Guidon, has tried to exorcise the geofact argument, which is used wherever tools are "too old", by showing that the 595 pieces of quartz have characteristics quite unlike those created by natural flaking. The doubters are unswayed. You see, despite Parenti's analysis, there remains a minute chance that a falling rock will fracture into pieces, one of which will look human-made. Maybe only one falling rock in 10,000 will fracture "unnaturally;" make it one in 10,000,000; it doesn't matter. Anthropologist D. Meltzer writes: "Of course, no matter how rare the chances, given sufficient time and raw material - Pedra Furada had plenty of both - nature can magnify even the slimmest odds to the point where geofacts occur in detectable frequencies." In this argument, you see how our title "Darwinism in Archeology" came to be. Random events (rock falls or mutations) plus a sorting mechanism ...

Primordial carbon may come from limestone or natural gas welling up from the earth's interior. Modern life forms that metabolize primordial rather than atmospheric carbon dioxide, with its cosmic-ray produced carbon-14, will appear extremely old when carbon-dated. For example, M. Grachev et al carbon-dated flatworms and a sponge collected from a bacterial mat near a thermal vent 420-meters deep in Lake Baikal. The apparent ages of these living organisms ranged from 6860 to 10,200 years. (Grachev, M., et al; "Extant Fauna of Ancient Carbon," Nature, 374:123, 1995) Even animals eating these apparently ancient life forms may take up their carbon-13 and, in effect, be drained of carbon-14. They would appear to age rapidly. Such false aging has actually been induced in the laboratory with mice fed on brewer's yeast grown in natural gas. These mice, living in cages at Lawrence Livermore National Laboratory, California, were carbon-dated as being 13,000 years old, and were expected to attain a ripe old ...

The presence of chloroplasts in plants, too, may have come about in this way. A case also exists for the alliance of spirochetes with cells to form flagella and cilia. These three "mergers" provided cells with metabolism, photosynthesis, and mobility. Margulis and Sagan obviously do not believe that the "bacterial connection" ended 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.

After all, the crop circles are about as outrageous as UFOs and toads-entombedin-stone. However, the crop circles have not gone away. In fact, plant and soil samples from the circles seem to point to bizarre, highly energetic processes at work. This aspect of the phenomenon has been discussed by R. Noyes, Secretary of the Center for Crop Circle Studies (CCCS). First, though, Noyes has asserted that hoaxes cannot explain the large numbers of circles that have been counted -- about 1000 between 1980 and 1989. He con tinued as follows: "The events of 1990 and 1991 (totalling about a further 1000 over the two years) certainly present a puzzle. Hoax is beyond doubt in some cases, but it seems very unlikely as a general explanation. Many events have been very large and very elaborate; they have occurred widely about the country (sometimes several on the same night in counties far from each other); there have been very few cases of detection of hoax, despite massive surveillance in the Mariborough/Devizes area, where so many of the events took place; circles (including a dumbbell formation) occurred within visual and radar range of a hi-tech ...

The animal is motionless, its senses are diminished; it is very vulnerable. Neither is there any provable biochemical value to sleep. (See BHF31 in Humans II) Yet, a large fraction of an animal's life is spent in this apparently useless and hazardous condition. Why, then, did sleep ever evolve? But with sleep, come dreams, and maybe an answer is to be seen in them. Cats establish long-term memories during sleep. First, it is relevant that an animal's brain (a cat's brain here) seems to be active even when an animal is sleeping deeply but not dreaming. It seems that during an extremely quiet phase of sleep, when researchers thought that nothing much was happening in the [cat's ] brain, groups of cells involved in the formation of new memories signal one another. The signals, discovered only a few years ago, allow cells in many parts of the brain to form lasting links. Then, when a few cells are stimulated during waking hours, the links are activated and an entire memory is recalled. Deep, dreamless sleep has long been thought to be of little value to an animal. Apparently this is not the case. Deep sleep seems to be valuable in memory activation. Score ...

But beneath the present parking area are post holes dated 4,000 years earlier!

This great effort required precocious social organization, communication, and some kind of psychological impetus. oThe sarsens -- those even bigger stones that define Stonehenge in our mind's view -- evoke the same sorts of questions as this issue's eccentric flints: Why? and How? Ruggles writes: "Why it was important to bring stones from so far away is an open question, as is the issue of how people achieved the almost unimaginable feat of hauling the sarsens, weighing 25 tonnes or more, over 30 km from the Marlborough Downs in the north." oNew studies of the other ancient monuments in the vicinity of Stonehenge have revealed that they were not placed at random.

The last close-up photo of Phobos snapped by the spacecraft contained "an object which shouldn't have been there." Naturally, this Phobos Mystery Object (PMO) was quickly dubbed a UFO by some. It was even speculated that the Russian mission had been deliberately terminated by aliens! Such a scenario dovetailed neatly with the old speculations that Phobos is actually an artificial satellite of Mars, which is being used as a base of operations by someone or something. The final photo of Phobos, taken in infrared light just three days before the communication failure, reveals the outlines of both Phobos and the PMO. All surface detail is washed out, as is common in infrared photographs. If the PMO was at the same distance as Phobos itself, it would be about 2 kilometers wide and 20 long. Its surface brightness is the same as that of Phobos. The sides of the PMO are perfectly parallel; it is rounded at both ends; the end towards Phobos narrows slightly; the other end seems to have a slight protrusion. Since the PMO does not appear to have a metallic surface and displays no antennas or other indicators of artificiality, it is reasonable to ask whether it might be some natural phenomenon.

Many dinosaur fossils have been dug up in Alaska, northern Canada, Siberia, New Zealand, and Antarctica. Not only were some dinosaurs cold-resistant but, seeing many were herbivorous, they were also able to migrate to more temperate climes as the long days of the polar summers waned. The point here is that the dinosaurs as a clan were very adaptable and should have survived severe environmental stress. (Vickers-Rich Patricia, and Rich, Thomas H.; "The Dinosaurs of Winter," Natural History, 100:33, April 1991.) That the polar regions were once covered by lush forests has been underscored by recent discoveries in both polar regions.

The effect is sometimes quite dramatic. There are accounts of a 'low roar' as the bands of breaking waves, 'walls of white water,' pass a vessel. The bands are sometimes visible from aircraft, on ships' radar and are observed from satellites. In the Bay of Biscay 'boils' have been reported on the sea surface in the calm zones, and appear to be related to pulses of nutrients from the thermocline." These surface phenomena are truly delightful and almost always the consequence of internal waves interacting with the surface. The great bulk of the referenced report is concerned with sonar observations of internal waves and their effects along the coast of Scotland.

"It has been suggested that the evolution of man took place in Africa. This suggestion results from the unusual abundance of fossil material in Africa that is quite ancient in comparison with what is known elsewhere. The theory of an African origin has influenced the interpretation of the age of some non-African archaeologial sites. A case in point is the 'Ubeidiya locality in Israel, which is generally considered to be about 700,000 yr old because it has been assumed by a few that the associated Early Acheulian tool industry, and the persons who used it, would have taken considerable time to disperse from Olduvai Gorge to this non-African site in Israel. Here we evaluate fossil mammals from 'Ubeidiya, which are stratigraphically and directly associated with Early Acheulian artifacts, and find no substantial reason for considering the locality younger than 2Myr, and possibly as much as 500,000 yr older than any record of Early Acheulian artefacts or Homo erectus in Africa."

Does this mean that the Big Bang, the mainstay of the astronomy we were taught in school, is now being cast aside? After all, the Big Bang does model fairly well three important observations: The apparent expansion of the universe; The 3 K microwave background; and The abundances of the light nuclei. But try as they may, cosmologists have not been able to coax the Big Bang model to explain the large-scale lumpiness and structure of the galaxies and galaxy clusters. One problem with the Big Bang is that it has too many free parameters -- too much theoretical slack. Many cosmologists are now looking for a better model. This better model, to use the words of P.

"Proper" siting and orientation were doubtless important to the builders of the megalithic structures, but can modern, no-nonsense science even begin to explore these mystical, psychic claims?

Among these are vast areas of previously unrecognized snow dunes -- all lined up in parallel like the ripples on a stream bed. However, these snow dunes are no ripples. They measure up to 100 kilometers in length with separations of 1-2 kilometers. They are, in fact, called "megadunes." At ground level, though, the snow dunes are not obvious because they are only a few meters high. Since Antarctica is often buffeted by fierce winds, one would naturally think that these snow dunes have an aeolian origin like desert sand dunes. This does not seem the be the case. Comparisons made using recently declassified images taken in the 1960s by U.S . military satellites reveal that the snow dunes have not moved in over 30 years! Some-thing besides wind-driven snow must be helping to sculpt these immense stationary patterns. (Tomlin, Sarah; "Vast Snow Dunes Frozen in Time," Nature, 402:860, 1999.) Comment.

If the large brightness changes are due to a highly irregular shape, Nereid's 660-kilometer size is too large, because astronomers agree that gravitational forces will sphericize all objects larger than 400 kilometers. On the other hand, if Nereid is two-faced, like Saturn's moon Iapetus (it's carbon-black on one side, light-colored on the other), astronomers are again faced with trying to explain how such a large solar-system object can acquire so much carbonaceous material on one side only.

As far as I know, there is no evidence to support this assumption. Indeed, there is a vast number of observations unaccounted for in the extant quantitative evolutionary theories. Many of these observations (inducible mutation systems, rapid genomic changes involving mobile genetic elements, programmed changes in chromosome structure) challenge the most fundamental assumptions which these evolutionary theories make about the mechanisms of hereditary variation and the fixation of genetic differences."

Some wing patterns blend into the background, making the butterfly hard to spot; other wings have prominent eyespots that are supposed to deter predators or trick them into striking at the wings instead of the soft, vulnerable body. But some tropi cal butterflies have a double problem; their predators change from dry to wet season. One butterfly, Orsotriena medus, masters this situation by changing wing patterns with the season. In the dry season, it is dark brown and inconspicuous; in the wet season, it switches to black wings with ostentatious eyespots and white bands. (Anonymous; "Cryptic Butterflies," New Scientist, 20, September 13, 1984.) The Asiatic freshwater clam has spread rapidly across North America since its accidental introduction about 50 years ago. In addition to its natural dispersal via its more mobile larvae, the young adult clams have a surprising method of hitchhiking rides on the water currents. Through their siphons they deploy long mucous threads. Water currents pull on these threads just as air currents catch the silken threads of migrating spiders. Given a water current of 10-20 cm/sec, the small clams manufacture and deploy their threads, and off they go downstream.

Commonly employed to "explain" patterns in nature, fractals are, from a simplistic viewpoint, mathematical ways to predict the development of a growing structure, be it a crystalline mass, a plant, or the universe-as-a -whole. Yes, the universe-as-a -whole, the clouds of stars and clusters of galaxies, may be mimicked by cellular automata (i .e ., fractals). Imagine the universe as a cubical lattice, and start in one corner, adding one layer of cubes after another. Galaxy distribution could be simulated by using a rule telling us which of the added cubical cells had galaxies in them and which did not. "The rule actually used supposes that the question whether each point in a newly added layer will (or will not) be occupied by a galaxy is mostly determined by the occupancy of the five nearest neighbors in the previous layer, but for good measure, there is a random variable to introduce an element of white noise to the system. To make the process a little more interesting, the determination whether a new site is occupied depends on whether a number characteristic of that site, and calculated by simple arithmetic from the corresponding number for the five nearest neighbors in the preceeding layer, exceeds an arbitrarily chosen number."

This is not true for dowsing. Serious dowsing claims, such as those made by Soviet geologists, which are difficult to account for in terms of the reception of normal sensory cues, may be explained by postulating human sensitivity to small magnetic field gradient changes. The theory is supported by a series of tests involving 150 subjects. "The magnetic theory predicts that dowsers can achieve above-chance re sults only if the features they claim to detect are associated with magnetic gradients of at least one nanotesla per metre.

In May 1987 a British submarine carried out an ice profiling experiment in the Arctic Ocean in which the route closely approximated that of an earlier voyage in October 1976. Over a zone extending more than 400 km to the north of Greenland there is evidence of a significant decrease in mean ice thickness in 1987 relative to that found in 1976. This thinning amounts to a loss of volume of at least 15% over an area of 300,000 km2 ." (Wadhams, Peter; "Evidence for Thinning of the Arctic Ice Cover North of Greenland," Nature, 345:795, 1990.) In an accompanying discussion of the ice problem, A.S .

Recent issues of Geology contain three fascinating papers relating to giant sea-bed pockmarks. In Ref. 1, J.T . Kelley et al describe a pockmark field in Belfast Bay, Maine. Here, the density of the pockmarks reaches 160 per km2, and they are apparently the largest pockmarks yet discovered.

Most European archeologists believe that primitive humans migrated northward from Africa into Europe, but the timing has always been a little fuzzy. The Europeans are willing to consider minor adjustments in the million-year figure. However, there are now several sites seeming to boast human artifacts that are about 2.5 million years old. This is just too old, and a debate has commenced. The most controversial site is Saint Eble, just below Mont Coupet, in southcentral France. Here one finds quartz fragments that look manmade to some archeologists, but seem products of natural fracturing to others. These crude objects are what some American archeologists call "Carterfacts," after G. Carter, who has found similar rock fragments in the Americas and dates them much, much earlier than 12,000 B.P . In Europe, there is little argument about the 2.5 -million-year-date for the stratum in which the controversial rocks are found. The debate is over whether they are natural or products of human manu facture. The French champion of human manufacture is E.

Rather, J. Maddox, the Editor of Nature, raised that red flag. To make things even worse, he subtitled his editorial: "Apart from being philosophically unacceptable, the Big Bang is an oversimple view of how the Universe began, and it is unlikely to survive the decade ahead." His philosophical objcections to the Big Bang are powerful: "For one thing, the implication is that there was an instant at which time literally began and, so, by extension, an instant before which there was no time. That in turn implies that even if the origin of the Universe may be successfully supposed to lie in the Big Bang, the origin of the Big Bang itself is not susceptible to discussion." The Big Bang, Maddox says, is no more scientific than Biblical creation! The scientific objections involve space, time, the curvature of space. The Big Bang further fails at explaining quasars and the hidden mass of the Universe. Maddox doubts that the Big Bang will survive the new data to be provided by the Hubble telescope.

Rubber gatherers of the region report that this fearsome creature emits a hideous odor and transfixes one with a paralyzing stare! It also seems impervious to spears and shotgun pellets. Natives and some cryptozoologists equate this animal to the legendary Mapinguari. P. J. Wynne's impression of South America's late-surviving giant sloth. D.C . Owen, an American biologist working with the Goeldi Natural History Museum in Belem, Brazil, has been tracking these stories.

As with the North American Bigfoot, hard data are elusive, particularly actual specimens, dead or alive. Owen is optimistic, however.

After some computations Melosh concludes: "It seems likely that the impacts that produced craters on Earth that are greater than 100 km in diameter would each have ejected millions of tons of near-surface rocks carrying viable microorganisms into interplanetary space, much in the form of boulders large enough to shield those organisms from ultraviolet radiation, low-energy cosmic rays, and even galactic cosmic rays.

Humphreys reviews a book that is just too expensive for us to consider buying. The title is: Synesthesia; A Union of the Senses . It costs $75 and is published by Springer/Verlag. The review, however, is expansive and provides some facts about synesthesia worth passing on to our readers. Syesthesia is an "oddity" of human perception in which words, musical instruments, objects, concepts, evoke sensations sharply different from what is actually being processed by the brain. For example, specific musical tones elicit specific color sensations; that is, B-flat evokes the color green; A-sharp, yellow, etc. Or the phenomenon may be more complex, with Mozart being green; Wagner, red, etc. Most "synesthetites" seem to experience colors, but geometrical figures sometimes appear in response to particular stimuli. As for the stimuli that call forth these exotic sensations; they are usually music or numbers. To some synesthetites, the cardinal numbers are associated with specific colors. The books's author is R.E .

Not to worry, say the modern-day Technocrats, we will launch nucleararmed rockets that will nudge such cosmic threats into harmless trajectories. These Pollyannas are presumptious. They assume that asteroids are hard, cohesive objects that will be shoved aside by a few megatons of explosive energy. There are two things wrong with this idea, and these reveal how radically our ideas about the nature of asteroids have changed in just 10 years. First, most astronomers will now agree that asteroids are orbiting rubble piles rather than monolithic objects. For example, the near-earth asteroid Mathilde, 53 kilometers in diameter, has a density of only 1.3 grams/cubic centimeter. Its porosity must be greater than 50%. It is not a hard, coherent object. Instead of a bullet, it is more like a cloud of shotgun pellets. It would be hard to divert all this debris with a nuclear blast. To make matters worse, asteroids like Mathilde are stickier than a cloud of buckshot. This fact is deduced from photos of asteroids showing many to be marked by huge craters.

A tall mirror was placed vertically on the table, perpendicular to the patient's chest, so that he could see the mirror reflection of his normal hand 'superimposed' on the phantom. In the first seven patients, when the normal hand was moved so that the phantom was visually perceived to move in the mirror, it was also 'felt' to move; that is, a vivid kinaesthetic sensation emerged. (These sensations could not be evoked with the eyes closed.) In patient D.S ., kinaesthetic sensations were evoked even though he had not experienced movements in the phantom for the preceding 10 years." Several patients that experienced pain in their phantom limbs (pain that can be excruciating) found that the pain disappeared when they could "see" their phantom limb in the mirror. Those who complained of the so-called "clenching spasms" in their phantom ...

Science Frontiers ONLINE No. 43: Jan-Feb 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Piscatorial Data Processing Mammals such as bats and porpoises have their acoustical navigational gear, while many fish have opted for electrical methods of scanning their surroundings. The short-range "radars" of these fish are marvelously sophisticated, considering the low limb fish occupy on the Tree of Life. In fact, the following introductory paragraph from an article in Nature sounds almost as if it came from a textbook on electronic signal processing. "Behavioural experiments have demonstrated that certain species of fish can perform remarkable analyses of the temporal structure of electrical signals. These animals produce an electrical signal within a species-specific frequency range via an electric organ, and they detect these signals by electroreceptors located throughout the body surface. In the context of one electrosensory behaviour, the jamming avoidance response (JAR), the fish Eigenmannia determines whether a neighbour's electric organ discharge (EOD), which is jamming its own signal, is higher or lower in frequency than its own. The fish then decreases or increases its frequency, respectively. To determine the sign of the frequency difference, the fish must detect the modulations in the amplitude and in the differential timing, or temporal disparity, of signals received by different regions of its body surface. The fish is able to shift its discharge frequency in the appropriate direction in at least 90% of all trials for temporal disparities as small as 400 ns." (Rose, Gary, and Heiligenberg, ...

... Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Did Mozart Use The Golden Section?Does the brilliance of Mozart's compositions derive entirely from his musical genius, or did he rely in part upon a mathematical construct: the famous Golden Section or Golden Ratio? The Golden Section is a mathematical formula for dividing into two parts: a geometrical line, a musical composition, or anything else possessing the property of length. The ratio of the two divided parts is the Golden Section, which equals 0.618.* For some artists, musicians, architects, the Golden Section is the most esthetic way of dividing the length of anything. For humans, the history of the Golden Section goes back at least as far as Euclid in 300 BC. For nature, it began eons ago: The shapes of pine cones, starfish geometry, and other dimensions of living things incorporate the Golden Section. The questions we address here are: (1 ) Did Mozart consciously make use of this ratio, 0.618, in his music? (2 ) Why is the Golden Section esthetically pleasing? It is not well known that Mozart was fascinated by mathematics as well as music. He even jotted down equations in the margins of some of his compositions. Chances are excellent that he knew of the Golden Section and its reputation for conferring elegance on structures -- even musical compositions. J.F . Putz, a mathematician, has measured some of Mozart's works. Mozart's piano sonatas were convenient targets, because in Mozart' ...

Science Frontiers ONLINE No. 60: Nov-Dec 1988 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Purposeful evolution?One seemingly unassailable dogma of evolutionary biology insists that natural selection involves, first, the continuous, random, environment-independent generation of genetic mutations; and, second, the subsequent fixation of those mutations that are favored by prevailing conditions. In other works, the genetic mutations cannot be influenced by external events and conditions. But in recent experiments with bacteria (E . coli), J. Cairns et al, at the Harvard School of Public Health, find they actually do produce mutations in direct response to changes in their environment. The adjective "purposeful" has even been applied to the action of these bacteria! Can anything be more heretical? "One of the experiments involves taking colonies of E. coli that are incapable of metabolizing lactose and exposing them to the sugar. If the lactose-utilizing mutants simply arise spontaneously in the population and are then favored by prevailing conditions, then this would lead to one pattern of new colony growth. A distinctly different pattern is produced if, under the new conditions, the rate of production of lactose-utilizing mutants is enhanced. The observation is something of a mixture of patterns, indicating that directed mutation appears to be occurring. 'This experiment suggests that populations of bacteria...have some way of producing (or selectively retaining) only the most appropriate mutations,' note Cairns and his colleagues." (Lewin, Roger; "A Heresy ...

... (71-75 million years ago). In 1993, about 1,000 fossils representing 20 species of mammals and reptiles were collected. Amazingly, these bones were not disarticulated, scattered about, or severely worn. It was obvious that the Ukhaa Tolgod animals had been very suddenly engulfed by a "tidal wave" of sand. It was a catastrophic event of some sort. But what kind of catastrophes occur on desolate, riverless deserts? Wind is always blowing sand about and dunes creep along in deserts, but healthy animals easily avoid burial. Of course, there are rare, sudden downpours even on the Gobi. But one would expect this rain to be quickly absorbed by the sand. Intrigued by the evidence of unexpected catastrophism in the Gobi, scientists from the American Museum of Natural History first took a look at Nebraska's strange Sand Hills. These Sand Hills stretch for thousands of square miles, reach heights of 400 feet, and are believed to be of aeolian origin during the Pleistocene. (See ETM7 in Carolina Bays ) Being a modern analog of the ancient Gobi, the Nebraska Sand Hills might provide some insights as to what happened long ago in the Gobi. An important clue occurs during the summer, when heavy thunderstorms sometimes trigger avalanches of wet sand called "debris flows". These sandslides may be 900 feet long, 50 feet wide, and 4 feet deep. Although they have occasionally partly buried ranch buildings, they are too slow and small to endangerlivestock and wild animals. But what if they were much larger and faster? Back on the ...

Nature. This editorial begins with: "Although the evidence now accumulating does not prove that the original observations of cold fusion were mistaken, there seems no doubt that cold fusion will never be a commercial source of energy." Editor J. Maddox concludes by stating that Pons and Fleischmann should have placed their responsibility to the scientific community above publicity.

Hippos have always seemed to be consummate herbivores; but in Hwange National Park, Zimbabwe, one killed an impala that had fled into a pond in order to escape a wild dog. It tasted good, and soon ten other hippos were enjoying a communal feast. (Anonymous; "Carnivorous Hippos," Natural History, 108:23, April 1999.) A Mom's Duty. The females of a small European spider, Amaurobius ferox , actively encourage their freshly hatched spiderlings to kill and eat them.
