... implies that evolution did not proceed as presently envisioned. (Rocks are often dated by their fossil contents.) So, geologists are left with the problems of sliding great masses of rock over rough surfaces for great distances. Sketch of the forces acting upon a thrust block being pushed by a wedge-shaped driver Low-angle thrust faulting is not a trivial geological process. To illustrate, the Lewis Overthrust in Montana and adjacent Canada involves the shoving of a block of old strata hundreds of feet thick, hundreds of miles long, over younger rock for a distance of possibly 50 miles. In contemplating such overthrusts, one immediately comes face to face with the Mechanical Paradox. Brief-ly, given the coefficient of friction between the layers of rock, the weight of the thrust block, ... the mechanical strength of the rock being pushed, it can be shown that pushing the thrust block at the rear edge will crush it long before it begins to slide. For nearly a century, geologists have been trying to resolve this Mechanical Paradox. Three potential solutions have been proposed: (1 ) Lubricate the sliding surfaces with water under high pressure (the pore-pressure approach); (2 ) Allow the thrust block to slide, not as a unit, but in small discrete areas at different times (the dislocation approach); and (3 ) Push the thrust block not only from the rear edge but along the top surface (the tapered wedge approach). In fact, all three solutions may apply; but there is no consensus so far. Each solution has problems ...

... formation in the bowl. Although the weather the previous day had been clement and the water was fluid, we had that night a sharp frost down to about -4 C. The following morning I noticed what appeared to be something sticking up out of the frozen water in the dish. On closer examination, it proved to be a solid 'spike' of ice, ending in an arrowhead. The ice was solid and came out of the side of the frozen water at an angle of about 45 . It was about 9 inches long and solid throughout." (Turner, Judy; "Spooky Spike," New Scientist, p. 54, November 2, 1991.) Two weeks later, the same journal published two radically different explanations of the ice spike. G. Lewis called the spike an "ice fountain" and stated that it is due to the well-known expansion of water as it freezes. R. Blumen-feld, on the other hand, attributed the growth of the spike to the fact that water molecules on the surface and in surrounding air are electrical dipoles. In his view, a small defect in the ice's surface attracts polarized water molecules in the air, creating an outwardly growing structure. (Lewis, Geoff, and Blumenfeld, Raphael; "Sprouting Spikes," New Scientist, p. 58, November 16, 1991.) Comment.

Hartley's studies of Braille readers. "A chance observation of a skilled blind reader led me to think that reading braille might provide a more natural task for studying the way in which people do two things at once. My studies of my colleague Lewis Jones suggest that he appears to use some form of parallel processing. Jones cannot recall whether or not he was taught to read Braille with two hands, but in common with other skilled readers of Braille, he has done so for many years. Jones' method of reading is typically as follows. The left forefinger starts to read the beginning of the line. It then meets the the right forefinger returning from the line above. When the two fingers touch, the right forefinger continues to read the line while the left forefinger returns to the beginning of the next line. The whole operation is quite smooth and cyclical, as the diagram...shows. However, I was startled to observe that the left forefinger starts to read the next line before the right forefinger has finished the line above. This overlap, demonstrated by my crude data, suggests that Jones appears to be using some form of parallel processing: it seems as if his brain stores initial information from his left forefinger before using it."

From the Abstract: "We studied the birth months of 3,556 schizophrenics at a Minnesota Veteran's Administration hospital before and after instituting corrections for year-to-year across-month variations in birthrates in our expected values and the age-prevalence bias toward the January-March seasonality effect described in some earlier studies. Finally, we reanalyzed our data on a subset of patients in whom the ageincidence effect should be minimal. Even after these corrections the results supported the contention that the winter birthrate for schizophrenics is excessive, at least in severe climates."

... Guadeloupe skeleton in limestone that seemed very ancient indeed from all indications. The article also stated that the British Museum had suppressed discussion of this paradigm-shifting discovery by hiding the skeleton away somewhere. It seems that the skeleton was never hidden and, in fact, was on public display between 1882 and 1967. The claimed Miocene dating of the skeleton has also been challenged, although no one seems to agree on just how old the bones may really be. The geological facts mentioned in SF#27 are not discussed at all in the article referenced below. A post- Columbian date was suggested on the basis that implements and a dog's skeleton were also found with the Guadeloupe skeleton. The whole business has split the ranks of British scientific creationists. (Howgate, Michael, and Lewis, Alan; "The Case of Miocene Man," New Scientist, p. 44, March 29, 1984.)

During the past 12,500 years, a deep accumulation of exceptionally dense peat has formed. The basal peat is lignitic, but is several hundred times too young to be a true lignite. This peat does not decay as rapidly as it should, given its populations of bacteria, yeasts, and other fungi. The peat accumulates about ten times faster than in other peat-forming regions. The authors conclude that the peat-forming process is poorly understood. (Smith, R.I . Lewis, and Clymo, R.S .; "An Extraordinary Peat-Forming Community on the Falkland Islands," Nature, 309:617, 1984.) Comment.

Science Frontiers ONLINE No. 6: February 1979 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Unearthly Life On Mars From the media standpoint -- and therefore that of most people -- the Viking Martian biological experiments were uncompromisingly negative. However, R. Lewis points out that this is simple not so. The labelled-release experiments on both landers produced positive results every time a nutrient was added to fresh Martian soil. (The nutrient was tagged with carbon-14, and radioactive carbon dioxide always evolved, suggesting biological metabolism.) Further, the soil samples, when sterilized by heat, gave uniformly negative results. On earth. such repeatable experiments would be considered strong evidence that life existed in the samples. The reason the Viking experiments were described as "negative" is that the other two life detection experiments produced negative or equivocal results. The gas chromatograph, for example, detected no organic molecules in the Martian soil; and it is difficult to conceive of life without organic molecules. At first, most scientists preferred to explain the ambiguous life-detection-experiment results in terms of strange extraterrestrial chemistry. Nevertheless, strange extraterrestrial life would explain the data equally well. Everyone should be aware that the Viking biology team still considers life on Mars as a real possibility.

... of the pressure in the zone where the shearing occurs showed it to be some 20 bars higher than the equilibrium pressure of 550 bars. This higher pressure may support the theory that low-angle thrust faults many kilometers wide are physically possible because high pressure fluids lubricate the shear zone, allowing massive thicknesses of sediments to slide over one another without resulting in wholesale fracturing and obvious damage. (Anderson, Roger, N.; "Surprises from the Glomar Challenger," Nature, 293:261, 1981.) Comment. Scientific creationists have long thought that the many low-angle thrust faults, where many miles of older rock are superimposed on younger rock, contradict geological dating schemes and therefore the theory of evolution. Establishment geologists, although somewhat amazed at the sizes of some of the overthrusts, especially one in Wyoming, have never despaired of finding a reasonable physical mechanism that would preserve the Law of Superposition and the idea of dating rocks by their included fossils. The Glomar Challenger results should buoy their spirits. Nev-ertheless, we must wonder how widespread stratum shuffling really is.

... 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.

Gold, of Cornell, theorizes that a vast reservoir of methane resides in the earth's crust -- a left-over from the formation of the earth. This accumulation of methane, he suggests, has been the major source of carbon at the surface throughout geological time. The existence of subterranean methane is manifested when flames shoot up during earthquakes. Tsunamis or tidal waves are probably caused by the release of immense bubbles of methane during quakes rather than by actual motion of the sea floor. (Lewis, Richard S.; "Is the Earth a Giant Methane Store?" New Scientist, 78:277, 1978.) Comment. Gold has also correlated offshore booms with sea-floor methane releases.
