Such flips can of-ten be correlated with climate changes, global ice volumes, sea-floor spreading rates, and deposition of black shales, tektite falls, biological extinctions, etc. The frustrating thing is the lack of clear-cut cause and effect; that is, how these phenomena are linked physically to the geomagnetic field. Part of the problem is that we can only guess at how the geomagnetic field is generated. Let us assume that the earth's magnetic field is created by dynamo action in the planet's fluid core. P. Olson finds analytically that the core dynamo may reverse sign due to fluctuations in core turbulence caused by two competing energy sources: heat loss at the mantle-core boundary and progressive growth of the inner core. In concept, the heat lost at the core-mantle boundary might be linked to climate changes and sea-floor spreading. Taking a different tack, D. Gubbins has investigated the possibility that field reversals are triggered by ice ages and meteorite impacts (tektite falls). The physical mechanism here would be the increase in pressure upon the core, which affects the rate of freezing in the outer core, and thus the power available to the core dynamo. Gubbins found that these externally caused pressure changes were too small to explain the polarity changes. However, the parameters involved ...

Science Frontiers ONLINE No. 37: Jan-Feb 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Recent Pulsations Of Life At a recent meeting of scientists at the Lamont-Doherty Geological Observatory, E. Vrba, of the Transvaal Museum, in Pretoria, stated: "If we eventually are able to establish a good time resolution with the continental record, I expect to be able to discern synchronous pulses of evolution that involve many groups of fauna and flora. Many different lineages in the biota will respond by synchronous waves of speciation and extinction to global temperature extremes and attendant environmental changes. This is my starting hypothesis." Vrba was speaking mainly about the last 25 million years, a mere flash in geological time. For this brief period, the Deep Sea Drilling Program has provided geologists with a detailed and continuous record of climate changes as they were recorded in deep-sea sediments. By contrast, the faunal history of the continents is rather fragmentary, making it rather difficult to match up pulsations of climate with pulsations of life. Even so, scientists have found rather strong correlations between climatary change and biological speciation and extinction at 15, 5, and 2.4 million years ago. (Lewin, Roger; "The Paleoclimatic Magic Numbers Game," Science, 226:154, 1984.) Comment. Note that this is just the period our ancestors seemed to be evolving rapidly. Also interesting is the general agreement between Vrba's statement about the driving forces behind evolution and McClintock's conclusion quoted earlier ...

Fairall has reported an "impossible" physical situation -- a strong scientific anomaly. It seems that a Seyfert galaxy (a very low-luminosity quasar) emits forbidden spectral lines that vary in intensity about every 30 minutes. It is not the "forbidden" character of the spectral likes that disturb the astronomers. (" Forbidden" simply means "improbable" in spectroscopy!) Rather, it is the half-hour variations that pose the dilemma. This is because most astronomers are convinced that the said forbidden lines are emitted by regions of the quasar that are 100-10,000 light years across. A disturbance or physical change leading to a variation in intensity, even travelling at the speed of light, could not begin to move across this huge region in half an hour. Yet, the changes in intensity seem to be there, inferring a physical change that travels perhaps a million times faster than physics permits. Variations in intensity decades long would be acceptable, but half an hour is out-of-the-question! The author of this referenced comment in Nature believes that the observational procedures employed must be at fault. (Gaskell, C. Martin; "Spectra That Defy Explanation," Nature, 304:212, 1983.)

However, the appearance of Terra Australis Re on Orontius Finaeus' map of 1531 and the depiction of a nearly identical continent on Mercator's 1538 map reveal sufficient, accurate knowledge of Antarctic features for us to conclude that someone discovered and mapped Antarctica well before 1500. The question is: Who? An interesting feature of Fineaeus' map is the reduced ice cover compared with what we find today. The Ross Ice Shelf, for example, was almost nonexistent. Such changes in ice cover are consistent with the modern theory of Antarctic climate changes. Apparently, the seas surrounding Antarctica were a bit warmer before 1500, and some unidentified early mariners brought knowledge of this continent back to Europe. (Weihaupt, John G.; "Historic Cartographic Evidence for Holocene Changes in the Antarctic Ice Cover," Eos, 65: 493, 1984.) Comment.

Weihaupt's paper on possible recent changes in the Antarctic ice cover (summarized in SF#36) evidently stirred up considerable scientific interest. Two long letters and Weihaupt's reply have recently been published in Eos. First and significantly, Weihaupt's omission of any reference to Hapgood's popular work, Maps of the Ancient Sea Kings, was pointed out and belatedly acknowledged by Weihaupt. The second letter was from a French scientist, who concluded that: ". .. in spite of some hard facts and in spite of warnings against simplistic theories, the idea of fast changes in the Ross Ice Shelf and its main nourishment area, Marie Byrd Land, is widespread in the United States." Weihaupt responded to this with a massive bibliography supporting the idea of recent, rather extensive changes in the Antarctic ice cover. He stated further that other research suggests that even the East Antarctic Ice Sheet may have undergone deglaciation during the Pleistocene. Those old maps showing Antarctica largely ice-free may not be so crazy after all. (Milton, Daniel J.; "Antarctic Ice Cover," Eos, 65:1226, 1984.) Comment.

The usual effect of a parasite upon its host is debilitation, often to the point of death. But parasites have to reproduce, and some settle for the modification of their hosts in ways that improve their chances. Parasites can change the size, color, and even the behavior of their host. The object is usually to encourage a specific predator to eat the host so the parasite can continue its life cycle. A classic example is the lan-cet fluke which infests ants and then sheep. The problem is that sheep don't normally eat ants, giving the flukes a chance to switch vehicles. So, the innovative flukes somehow force the ants to crawl to the tops of plants and lock themselves there with their jaws. The next hungry sheep that comes along has his meal seasoned with ants. The bulk of the present article deals with thorny-headed worms, which are not as endearing as the lancet flukes. These parasites are merely bags of reproductive organs attached to a thorny probiscus, by which they attach themselves to the intestinal walls of vertebrates. Living in a sea of processed nutrients, the worms don't even have a digestive tract. Part of the life cycle of this parasite is spent in arthropods (insects, crustaceans).

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.

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."

... in essence declared that from statistical considerations life could not have arisen and evolved on earth. Rather, life had to come from outer space, probably in the form of bacteria and viruses. Evolution was and is dependent upon new information arriving from outer space on tiny bits of life. Hoyle now greatly extends his theory: "But where did a knowledge of amino acid chains of enzymes come from? To use a geological analogy, the knowledge came from the cosmological equivalent of a previous era, from a previously existing creature if you like, a creature that was not carbon-based, one that was permitted by an environment that existed long ago. So information is handed on in a Universe where the lower symmetries of physics -- and characteristics of particles and atoms -- are slowly changing, forcing the manner of storage of the information to change also in such a way as to match the physics. It is this process that is responsible for our present existence, and it is the one which our descendants would be fated to continue." To continue his search for the ultimate, Hoyle recognizes that, contrary to what transpires in the inorganic world, life as-a -whole is actually gaining order and information. He sees life leading the universe forward to a remarkable future: "That biological systems are able in some way to utilise the opposite time-sense in which radiation propagates from future to past.

R.D . Purrington, in the first of a pair of papers in American Antiquity, maintains that the Poverty Point ridges have been so badly eroded over the last 3,000 years that sight lines cannot be determined with any accuracy. In fact, the precise center of the octagonal figure is a matter of judgment. Purrington's reconstruction of sight lines along the avenues, using his assumed center, does not support the idea that the avenues were solstice markers. Brecher and Haag responded in the second paper that their viewing center is 100 meters from Purrington's . With this change. they claim good fits for two of the avenues as solstice markers. One of the two remaining avenues turn out to mark the setting of Canopus, the second brighest star in the sky. Even the unassigned last avenue has astronomical significance; it marks the setting of Gamma Draconis, a second-magnitude star, which the ancients employed as a nocturnal hour hand as it swung around the pole star.

... The tiny granules of magnetite found in magnetized sediments come in various crystalline forms. Inorganic magnetite precipitated from molten rock is octahedral, while the particles manufactured by bacteria are cubes, hexagonal prisms, or noncrystalline teardrops. The magnetite found in marine sediments appears to be organically formed -- at least the shapes of the particles are characteristic of bacterial manufacture. Apparently these industrious bacteria have been busy producing magnetite ever since "lowly" life forms appeared in the Precambrian. These facts pose at least four questions: How much of the earth's iron ore has been concentrated biologically and is there a connection with the Gaia Hypothesis? Is it possible that magnetic field reversals, now believed to be of purely geophysical origin, might be biological artifacts (that is, due to population and/ or species changes of magnetic bacteria)? If magnetic field reversals are of geophysical origin, how do the magnetic bacteria find their food sources during the long periods of near-zero field? Lab experiments prove that magnetic bacteria require free oxygen to secrete magnetite, but the Precambrian atmosphere and oceans were supposedly devoid of oxygen until 2.3 billion years ago. How did the magnetic bacteria prosper before then? (Simon, C.; "Tiniest Fossils May Record Magnetic Field," Science News, 124:308, 1983.)

As a matter of fact, one characteristic of a scavenger species is its ability to cover wide areas with little expenditure of energy, like the vultures. Now, human bipedalism is pitifully poor for running down game but great for searching far and wide with minimum physical effort.

Then, according to toothwear patterns, there was a shift to a mainly meat diet. This was also the time when human territory expanded greatly geographically. The reason for these changes is unknown.

Maddox lists several specific candidates, and then observes: "The more radical psychoimmunologists talk as if there is no state of mind which is not faithfully reflected by a state of the immune system." So far, not too radical! But then Maddox comes to an article by J.E . Blalock, University of Texas (Journal of Immunology, 132:1067, 1984.) bearing the title, "The Immune System as a Sensory Organ." Blalock argues that the interaction between the central nervous system and immune system must be reciprocal. By this he means that the immune system's response to infection, through the secretions of disease-fighting lymphocytes, gets back to the central nervous system and produces physiological and even behavioral changes in the infected animal. Applicable studies of animals have been reported recently. For example, rats under stress are found to have less easily stimulated immune systems. (Science, 221:568, 1983.)

They also address the puzzling question of what forces may be at work when stroke victims partly recover. Do 'redundant copies' of skills exist outside the damaged regions, or is physical damage within the brain repaired over time? Or can old skills be newly established in different, undamaged brain regions." Apparently the brain should really be compared with a reprogrammable computer.

Rather, they seek out low resistance rocks, in accordance with Ohm's Law. Such current concentrations can be detected at the surface with magnetometers. The present paper announces the discovery of a regional telluric current flowing in the vicinity of the San Francisco Peaks volcanic field in Arizona. The shallow part of the current flows in an unidentifiable "geoelectrical" structure not more than 10 kilometers below the surface. There are no surface hints as to what this geoelectrical structure could be.

In the present item, Williamson complains that scientists and critics have focussed primarily upon his claim that his mollusc lineages support the punctuated evolution model (which they do) but avoid his main point: namely, that the lineages are static over very long periods of time. They do not change slowly, bit by morphological bit, into new species as an evolutionist would expect. Instead, they remain un-changed until they become extinct. This striking aspect of the fossil record is not predicted by neo-Darwinism -- and there is the rub! (Williamson, Peter G.; "Morphological Stasis and Developmental Constraint: Real Problems for Neo-Darwinism," Nature, 294:214, 1981.) Comment.

Molten material pushing out along these ridges spreads out, solidifies, and is magnetized by the prevailing terrestrial magnetic field. Thus, the spreading sea floor becomes a "tape Recorder" preserving the record of changing terrestrial polarity over the past several hundred million years. As one drills into this thin conveyor-belt/tape-recorder, one would expect to encounter only rocks of one polarity. Not so! Some of the holes drilled by the Deep Sea Drilling Project have passed through several polarity zones. To illustrate, core 395A from the mid-Atlantic ridge is magnetized normally for the upper 170 meters, reversely for the next 310 meters, and normally again for 40 meters.

Even if psi is real, it cannot become part of the scientific belief system until dogmas about the nature of life and man change. From Science Frontiers #21, MAY-JUN 1982 . 1982-2000 William R.

... part of a complex social "superorganism," the termite colony. That termites had bugs in-side them has long been known; but the new-found complexity and interdependency of life systems within life systems is remarkable. The researchers believe that the life forms inside the termite work together to create the uniform internal environment needed by all inhabitants, just as the termites themselves cooperate to maintain a favorable environment inside their hill. (Anonymous; "And Littler Bugs Inside 'Em," Scientific American, 246:78, February 1982.) The termites, though, are only part of a much larger ecosystem, the earth itself. J.E . Lovelock, in his Gaia, A New Look at Life On Earth, has observed that our planet's environment has actually changed little down the eons despite solar variations. Lovelock's hypo thesis is that all terrestrial life -- animals, plants, termites, etc -- work sym biotically to maintain planetary temperatures, atmospheric constituents, etc., conducive to life, just like the termite's internal residents on a much smaller scale. The Gaia concept was restated by R.A . de Bie in a letter to Nature about the possibility of life in outer space. He observes that terrestrial life, according to Gaia-thought, will naturally develop a species that can carry life off the planet to new and safer environs. Humankind, of course, is the first attempt we know of to create such an agent. Other planetary systems might have differently constituted agents. (de Bie, Roeland ...

... gases escaping from deep within the earth. Perhaps some petroleum and natural gas reserves have been created by primordial hydrocarbons working their way outward through the crust rather than by the geochemical alteration of biological materials. Perhaps almost all petroleum is abiogenic -- some Russian scientists hold this view! Western scientists are almost unani-mous that natural gas and oil are bio genic with maybe a touch of upwelling abiogenic hydrocarbons. A major reason given for this stance is that the biogenic theory has been so productive in locating hydrocarbon reserves. This, of course, leaves the earthquake lights and sounds still unexplained. (Anonymous; "Abiogenic Methane? Pro and Con," Geotimes, 25:17, November 1980.) Comment. The moral of this might be that seemingly inconsequential phenomena historically lead to wholesale changes in scientific thinking; viz., the insignificant advance in Mercury's perihelion. Reference. The possible abiogenic origin of natural gas is covered at ESC16 in Neglected Geological Anomalies. For a description of this Catalog, visit: here .

... BP) formation called the Burgess Shale has miraculously preserved a vast assemblage of soft-bodied sea creatures, especially arthropods. Does this rich and unusual deposit help elucidate arthropod evolution? No, it has complicated the problem. Few of the fossil arthropods can be easily related to groups now living. The Burgess Shale arthropod population is primitive in some ways but remarkably specialized in others. Some of the fossils have body segments like those in one recognized arthropod group but display limbs resembling those of an entirely different group. (Fortey, R.A .; "The Burgess Shale: A Unique Cambrian Fauna," Nature, 293: 189, 1981.) Comment. It appears that Nature was shuffling the gene deck, or that there was rampant hybridization, or that confusing programs for evolutionary change were drifting in from the cosmos a la Hoyle and Wickramasinghe!
