Much at-tention is paid to the evidence of sliding between beds (breccia, small overfolds, etc.). Some excellent photos of these contact planes are presented.

As the moonlets' orbits decayed, some crashed into the moon's equatorial regions, blasting out a band of huge craters. The force of the impacts also caused the lunar crust to slide over the still-liquid core by as much as 90 . When the next group of moonlets crashed, they gouged out a new belt of craters and shifted the crust still more. Magnetic measurements of lunar rocks tend to confirm that the lunar crust did indeed shift by large angles -- several times. (Anonymous; "Did the Moon Have Moonlets?"

In the frigid waters ringing the continent of Antarctica live approximately 275 species of fishes, 95 of which are assigned to the suborder Notothenioidei. This particular group of fishes is renowned for its unusual adaptations, as outlined below by D. Policansky: "Some of them have glycoprotein antifreezes in their blood, some have no hemoglobin, some have so small a temperature tolerance that they die at temperatures above 4 C, some are neutrally buoyant despite lacking swim bladders, and some live as deep as 2950 meters. The suborder has no known fossils, largely because no bony feature -- indeed, no single character of any sort -- can be used to define it. How did these animals arrive there, what are their ancestors, how do they make a living in such an environment, and how can they support commercial harvests?"

Levinton, in a long article in the November 1992 Scientific American, explores the enigma of the Cambrian explosion. Did some unknown evolutionary stimuli prevail 570 million years ago that made the Cambrian different from all periods that followed? Or, has something damped evolutionary creativity since then? Levinton holds that biological innovation has continued unabated at the species level since the Cambrian explosion, but that new body plans; that is, new phyla; have not evolved for hundreds of millions of years. Therefore, something special and very mysterious -- some highly creative ...

Instead, the ages seem to cluster at 7 and 30 million years." Astronomers have hitherto been content to attribute these clumped ages to collisions among the meteorites' parent bodies - the asteroids - which ply periodic orbits. However, S. Perlmutter and R.A . Muller, at Berkeley, point to the apparent 26- to 30-million-year periodicities of three terrestrial phenomena: Biological extinctions in the fossil record, Magnetic field reversals, and Terrestrial-crater ages. Could there be a connection between the clumped meteorite ages and these terrestrial phenomena? Perlmutter and Muller propose that all of these phenomena are the consequence of periodic storms of comets that invade the inner solar system from the direction of the Oort Cloud of comets that purportedly hovers at the fringe of the solar system. These comets not only devastate the earth but also collide with the asteroids, knocking off those bits and pieces we call meteorites. (Anonymous; "Do Meteorite Ages Tell of Comet Storms?" Astronomy, 17:12, January 1989.) Comment. Unanswered above is the question of why comet storms should be periodic. One hypothesis is that Nemesis, the so-called Death Star, a dark companion of our sun, lurks ...

... tectonic processes circulate the entire oceanic crust back into the mantle every 100 million years. Ero sion also removes part of the continental crust, and some of the eroded material may eventually find its way to deep oceanic trenches, where it is also returned to the mantle. This implies that at any given time only about 10% of the crust is at the surface. Much of the continental crust, however, is more than half the age of the earth, so one can infer this part has not recirculated recently." (Anderson, Don L.; "Where on Earth Is the Crust?"

... into the rocks of the Siljan Ring, Europe's largest known meteor crater. Oil and gas should not be down there in any quantities according to current theory, but that's what they are drilling for. Isn't it futile to fight such a well-established dogma that oil and gas have biological origins and therefore must be looked for only where life once thrived? Not any longer! Enough anomalies have accumulated to seriously challenge the idea that oil and gas are byproducts of ancient animal life. Here are a few of these anomalies: The geographical distribution of oil seems derived from features much larger in scale than individual sedimentary features. The quantities of oil and gas available are hundreds of times those estimated on the basis of biological origins. The so-called "molecular fossils" found in oil and claimed as proof of a biogenic origin are simply biological contaminants, particularly bacteria that feed upon the petroleum. Petroleum is largely saturated with hydrogen, whereas buried biological matter should exhibit a deficiency of hydrogen. Oil and gas are often rich in helium, an inert gas which biological pro cesses cannot concentrate. The great oil reservoirs of the Middle East are in diverse geological provinces. There is no unifying feature for the region as a whole and, especially, no sediments rich in biological debris that could have produced these immense concentrations of oil and gas. If oil and gas do not come from decaying organic matter, where do they originate? Some scientists, such as T. Gold, say "from the earth's core." As the earth accreted ...

It has now been discovered that clay samples from the Cretaceous-Tertiary boundary also contain 0.36-0 .58% graphitic carbon. It is fluffy stuff and suggests that the planet was once covered by a thick layer of soot. Quantitatively, the soot layer is equivalent to the carbon in 10% of the earth's present biomass. The authors speculate that this soot was created by huge wildfires that consumed much of the earth's vegetation and perhaps fossil fuel as well. Terrestrial life was, of course, devastated -- just as it is in the currently popular "nuclear winter" scenarios. The end-of-the-Cretaceous soot is in fact, thicker and more widely spread than nuclear winter theories predict. (Wolbach, Wendy S., et al; "Cretaceous Extinctions: Evidence for Wildfires and Search for Meteoric Material," Science, 230:167, 1985.) Comment. Questions arise, though: How could a single meteorite impact ignite worldwide wildfires? Why haven't other meteorite impacts, recorded abundantly by large craters and astroblemes, also set fire to the planet and left iridium layers?

... from birth to death. The fact that C.elegans is nicely transparent helps the cell-watcher. Here are some of the interesting things to be seen as cells proliferate, live, and die. First, C. elegans is bilaterally symmetrical, but the pattern of cell generation on the right differs from that on the left. Nevertheless, the creature ends up symmetrical, making one wonder where the directions for symmetry come from. Some cells are transients, dying when their jobs are done. A few doomed cells are generated only because they produce sister cells that are needed in the final animal. Such a programmed loss of cells may be a method of modifying an organism during evolution. John Sulston, one of the researchers, says, "Within the lineage you can see the fossil of its past." (Marx, Jean L.; "Caenorhabditis Elegans: Getting to Know You," Science, 225:40, 1984.) Comment.

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?

The utility of sleeping and dreaming do not seem at all commensurate with the accompanying vulnerability and the loss of waking hours. However, speculation is fun. There are at least two rather far-fetched explanations for characteristics (sleeping and dreaming here) that do not appear to have very much survival value. Sleeping and dreaming may be linked genetically to a characteristic that does have considerable survival value. Example: Resistance to malaria is coupled to sickle-cell anemia. Sleeping and dreaming may represent unavoidable, intermediate, evolutionary steps toward something of much greater value. Example: those fea- thers on fossil dinosaurs; i.e ., the protobirds.

In Storms' own words: "Evidence for large and reproducible energy generation as well as various nuclear reactions, in addition to fusion, from a variety of environments and methods is accumulating. The field can no longer be dismissed by invoking obvious error or prosaic explanations." (Storms, Edmund; "Review of the 'Cold Fusion' Effect," Journal of Scientific Exploration, 10:185, 1996.)
