... 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. (Prezant, Robert S., and Chalermwat, Kashane; "Flotation of the Bivalve Corbicula Fluminea as a Means of Dispersal," Science, 225:1491, 1984.) Australia boasts many peculiar animals and plants. One of these is an orchid that grows underground. Obviously this orchid cannot employ photosynthesis. Rather, it grows in conjunction with a fungus that obtains nutrients from surrounding roots. The fungal threads penetrate both roots and orchids. The orchids make ends meet by systematically killing and digesting the nutrient-laden fungal threads. When the orchid flowers, it pushes toward the surface just enough to open some tiny cracks in the earth. In these cracks, still below the surface, appear the tiny burgundy red flowers. These flowers are pollinated by minute flies, but just how the orchid's seeds are dispersed is still a mystery. (Cooke, John; "Hidden Assets," Natural History, 93:75, October 1984.)

... M. Sher, the universe-as-a -whole may undergo a phase change. Such an event has already happened once and it may again. Approximately 10-10 seconds after the Big Bang, the force laws changed discontinuously as the universe cooled. Some models of the cosmos predict that another such phase change may occur when photons suddenly acquire mass. Grone and Sher have sketched the effects on terrestrial civilization: "The most dramatic effect would be the elimination of all static electric and magnetic fields over a range greater than 1 cm, and the elimination of all electromagnetic radiation with frequencies smaller than a few hundred gigahertz. We have shown that there would be relatively little impact on atomic structure and on solar radiation. The absence of electrostatic fields would force a redesign of current power plants (to use smaller solenoids); the absence of radio and television waves would force a much greater use of cables. The elimination of solar and geomagnetic fields would have a significant meteorological impact. The potential ly most devastating effect could be on the propagation of neural impulse along motor neurons; it appears that the effects might be small, but they do depend on the precise value of the photon mass." Crone and Sher conclude that the effect would be devastating to humanity but probably not fatal.

It appears to contain a complex set of data pertaining to the cosmology of the relatively unknown Indians who inhabited the Jalisco coast during the last Pre-Hispanic period. Analysis of the scar has incorporated both the artistic symbolism of the nearby Huichol Indians, and concepts developed through archaeoastronomy. This analysis suggests that the ceiling pictographs record the use of sky transits of the sun, Venus, or the constellation Orion as wet season/dry season calendric markers. Wall pictographs show the sun on the mountainous horizon, below which is the earth filled with symbols of plants and animals, among these stand shamans calling down the life-giving rain from the god(s ) of the sky.

Early the next morning, people in a van driving past the lake discovered the body of a motorcyclist. The air smelled like battery fluid. One of the van's occupants collapsed. The others ran for their lives toward Njindom. By 10:30 AM authorities had found 37 bodies along a 200meter stretch of road by the lake. Blood was oozing from the noses and mouths; the bodies were rigid; first-degree chemical burns were present. Also, animals and plants along the shore had been killed. On August 17, the lake turned reddish brown, indicating that it had been stirred up somehow. Although Lake Monoun is in a volcanic crater, chemical analysis of the water found little of the sulphur and halogens normally associated with volcanic action. However, the analysis did find a tremendously high level of bicarbonate ions, which form from the dissociation of carbon dioxide. One theory is that an earthquake disturbed the carbonate-rich deep water of the lake, which as it rose to the surface and lower pressures, released huge volumes of carbon dioxide -- something like opening a soda bottle. The resulting wave of water and cloud of gas caused the deaths and devastation. If there had been some nitric acid in the cloud, the burns could be ...

Bacteria, which are usually regarded as fairly inert when it comes to responding to environmental pressures, actually react in different ways to dozens of different stimuli. This ability at the very least requires sensory equipment, internal clocks, a memory, and a decision-making capability. If bacterial activity is all preprogrammed (the reductionist view), are not humans also preprogrammed? Human programs are larger and more complex, of course, but still devoid of "thinking." Conversely, if humans really do think; that is, transcend preprogramming (free will, if you wish), then bacteria must also think. The third possibility is that at some step in the ladder of life, "higher" life forms begin to think. There is little evidence that life is split so profoundly between thinkers and non-thinkers.

The earth, it appears, is a veritable Gene sis Machine; and it is only one planet among a possible infinitude. So many terrestrial species have already been described that one could easily believe that biological collectors roaming the planet's wild places have just about completed their task.

However, all anomalists recognize that "official" stories often sweep untidy facts under what has come to be an immense rug. One seldom mentioned and rather awkward bump beneath this rug is Cuna writing. The Cuna Indians occupied Panama and some nearby Caribbean islands at the Time of Contact. That the Cuna carved symbols of sorts on wooden boards and scribbled with natural pigments on bark cloth and paper is generally admitted, but this is not considered in the same league as Mayan writing. A sample of Easter Island "writing" from a talking board Cuna writing is ideographic. Today's average Cuna Indian can usually identify each ideogram as a bird, plant, or some other object.

Many species changed rapidly and in concert. (2 ) A recent Science article (228: 1187, 1985) notes that inbred mice often evolve different morphological characteristics very quickly.

May ponder in Nature : "Why there should be such exuberant biological diversity in an environment apparently lacking in the habitat complexity of, say, tropical rain forest -- whose species richness it might rival -- remains an enigma." In fact, the enigma becomes more profound when one finds there exists a "depth effect" paralleling the terrestrial "altitude effect." "This phenomenon is associated with an increase in species richness with depth, and is essentially like the pattern of increasing numbers of plant and animal species as one moves down from mountain tops to sea level."

For example, Van Valen's list of objections to the hypothesis of asteroid impact at the Cretaceous-Tertiary boundary was reproduced in the last issue of Science Frontiers. Now, in a recent issue of New Scientist, T. Hallam raises still more objections: Tropical plants, mammals, crocodiles, birds, and benthic invertebrates were little affected by whatever happened at the Cretaceous-Tertiary interface. Furthermore, many groups that were extinguished were already well into a decline. Some geologists insist that some of the supposedly synchronous extinctions were probably separated by several hundred thousand years; viz., plankton and dinosaurs. The vaunted iridium anomaly in deep-sea cores is spread through a considerable thickness of sediment. Even after allowing for the mixing of sediments, the iridium-rich layer is thousands of years thick. According to the asteroid scenario, the clay layer separating the Cretaceous from the Tertiary should represent the fallout from impact-raised dust, which would include asteroidal material and a mixed sample of earth rocks.

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.

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.

... Project Sourcebook Subjects Remarkably Early Dates For Agriculture B.K . Maloney, of the British Museum, describes his pollen analysis of sediments that have accumulated in the Toba Highlands of North Sumatra, Indonesia. The base of a 9.7 -meter core from the Pea Sim-sim Swamp has yielded a radiocarbon date of 18,496 years. Pollen studies of the core indicate a brief decline of forest pollen about 17,800 BP along with increased sedimentation characteristic of cleared land. Taken by themselves, these data would probably be interpreted in terms of natural climate changes. But extremely early dates for human activity exist nearby: 14,000 BP for agriculture in Thailand and 11,000 BP for forest clearance on Taiwan. It is possible, therefore, that men were clearing land for planting in North Sumatra almost 18,000 years ago. (Maloney, B.K .; "Pollen Analytical Evidence for Early Forest Clearance in North Sumatra," Nature, 287:324, 1980.) Comment. Some archeologists hotly disoute the early dates mentioned above.

... Science Frontiers ONLINE No. 111: May-Jun 1997 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Carnot Creatures Photosynthesis is the ultimate source of energy for most of the life forms we recognize here on earth. Sure, there are also a few creatures that derive their energy by oxidizing the sulfides dissolved in the 400 water gushing forth from deep-sea vents. We will call them "geochemical creatures" to separate them from the "photosynthetic creatures" we are more familiar with. But, in principle at least, there could also be "Carnot creatures", whose metabolisms depend upon temperature differences like almost all human-built engines. Some bizarre animal, such as a meter-long tube worm, could plant one end on a hot rock surface and dangle the other in cold seawater to reject waste heat from its Carnot engine. Since thermodynamic-cycle efficiencies can approach 60% compared with only 10% for photosynthesis, evolution would have been remiss if it had not tried to evolve "Carnot creatures." For, as D. Jones comments below, Carnot creatures would be adaptable to many more habitats in the universe than photosynthetic creatures, which must have a sun with a very specific electromagnetic spectrum. "Many worlds, from distant 'brown dwarf' stars to the satellites of giant planets, may have internal heating but no effective 'Sun'. If Carnot life is possible, it may well have evolved in such dark and distant places -- making life abundant throughout the Universe. Indeed, our distant ...

... are the peculiar glassy clinkers of fused wood ash found in hollow snags in trees after intense forest fires. This is called "combustion metamorphism." Combustion metamorphism is also common where undergound coal seams have caught fire and burn for decades. Humans get into the act, too. The ancient Scots piled up trees around their rock forts and fused the stones together with fire. (Why they bothered is unknown.) However, a different sort of natural glass has been found in east-central Botswana. There, archeologists have found 5-inch-thick layers of glassy slag interleaved with ashy soil in ancient middens (garbage dumps). These middens are not associated with pottery kilns or iron smelting. It is hard to imagine what could have melted layers of garbage, including pottery, plant material, and other biomass. Analysis of the slag indicates that temperatures of 1155-1290 C were required to fuse the garbage. Open fires could not have attained the necessary temperature. The slag layers encompass several hundred square meters, so the phenomenon is not a trivial one. Combustion metamorphism may be the answer to this puzzle. Lightning or grass fires might have ignited buried biomass layers. Being confined like burning coal seams, the fires could have generated the required very high temperatures. (Thy, P., et al; "Implications of Prehistoric Glassy Biomass Slag from East-Central Botswana," Journal of Archaeological Science, 22:629, 1995.) Comments. It is unlikely that lightning would strike the same middens repeatedly to create the separate layers of slag. It ...

... related to watercourses. Also, many of the lines definitely functioned as footpaths. It was also apparent that the animal figures, which were laid down much earlier than the line systems, were not related conceptually to the line scheme. Aveni concluded: ". .. whatever the final answer may be to the mystery of the Nazca lines, this much is certain: the pampa is not a confused and meaningless maze of lines, and it was no more intended to be viewed from the air than an Iowa wheat field. The lines and line centers give evidence of a great deal of order, and the well-entrenched concept of radiality offers affinities between the ceque system of Cuzco and the lines on the pampa. All the clues point to a ritual scheme involving water, irrigation and planting; but as we might expect of these ancient cultures, elements of astronomy and calendar were also evident."

... mix. The once-independent and widely different cell nuclei will fuse, forming a single hybrid cell with a common membrane. Even more astonishing, this totally new biological entity will often divide and produce an endless line of the new hybrid. As might be expected, some hybrids do not remain true and revert to one or the other of the original species. Although cell fusion has been observed only under laboratory conditions, it seems to represent a near-universal cell phenomenon that might be realized rarely under natural conditions. The implications for the history of life are far-reaching. For example, the mitochondria in human cells that help our bodies use oxygen to obtain energy may well be descendants of bacteria that once fused with primitive cells. The same may be true for the chloroplasts in plant cells. (Thomas, Lewis; "Cell Fusion: Does It Represent a Universal Urge to 'Join Up'?" Science Digest, 86:52, December 1979.) Comment. Natural cell fusion might make large evolutionary steps possible and be much faster than endless small genetic changes. Are we all composite creatures?
