At first expanding rings of fungus infection were suspected, something perhaps like the fungus that creates those fairy rings on lawns. But no fungus has been found on the tree roots. One curious fact was discovered about the soil where tree growth is sparse. The soil constituting the rings is poorly drained and is depressed 1-2 meters below the surrounding healthy forest. These circular depressions support mainly peat and tamaracks. But what causes these ring-shaped depressions? One theory holds that the rings are the suface expressions of diamond-bearing kimberlite pipes, like those in South Africa. A few prospectors are already staking diamond-mine claims! Another theory supposes that the rings are created by huge, natural electrical batteries that exist in the carbonate soil. The current flow supposedly creates acidic conditions that eats away at the soil causing it to slump in a circle around one terminal.

... So, African Eve, if she ever existed, is probably twice as old as originally thought. (Day, Michael; "All about Eve...," New Scientist, p. 4, March 13, 1999.) Maybe There Were Two Eves! Not only has African Eve aged precipitously but there may have been a non-African Eve, too. J. Hey and E. Harris, at Rutgers, have presented data suggesting that the famous African Eve was the mother of only modern sub-Saharan Africans. Everyone else seems to have descended from an entirely different Eve. These data, if confirmed, demolish the African Eve theory and support the often-reviled multiregional theory of humans origins.

Genetic Clocks Are Fickle. mtDNA clocks have implied that modern birds and mammals were contemporaneous with dinosaurs, and that some animals evolved millions of years before their first fossils. For good reasons, evolutionists are becoming wary about these molecular clocks. It is fast becoming obvious that: "Clocks tick at different rates in different lineages and at different times.

Scientists have been known to "spin" data like politicians! A classic case of scientific "spin" occurred in connection with the total solar eclipse of 1919. British astronomer A. Eddington had mounted expeditions to Sobral, Brazil, and the island of Principe off the west coast of Africa. He had telescopes set up at these two locations to measure the bending of starlight by the sun, as predicted by Einstein's Theory of Relativity. In 1919, Relativity was not yet the cornerstone in the Temple of Science that it is today. Eddington "believed" in Relativity and wished to make it more acceptable. Eclipse photos showing the shifting of star images by the gravitational influence of the eclipsed sun might do the job. On the day of the eclipse, Principe was bedevilled by clouds, and only 2 photographic plates were deemed marginally acceptable. At Sobral, 18 poor plates and 8 better plates were obtained. The problem was that the 18 poor plates yielded a deflection of starlight much smaller than predicted by Relativity, while the 8 better plates produced a much higher value. By adding the 2 plates from Principe to the mix, Eddington managed to come up with a number close to that required by the ...

... one point during the last 400,000 years, the human population worldwide was reduced to only about 10,000 breeding men and women -- the size of a very small town. What caused this population "bottleneck"? Did a population crash engulf the entire globe. If not, who was spared? Such questions arise from a surprising observation: Human DNA is remarkably uniform everywhere humans are found. This hidden genetic uniformity is difficult to believe if one strolls through a cosmopolitan city like New York or Paris. Nevertheless, compared to the DNA of the great apes, whose mutation rates should be close to ours, human genes on the average show far fewer mutations. Human DNA from Tokyo and London is more alike than that from two lowland gorillas occupying the same forest in West Africa. Harvard anthropologist M. Ruvolo has commented: "It is a mystery that none of us can explain." The clear implication is that humans recently squeezed through a population bottleneck, during which many accumulated mutations were wiped out. In a sense, the human race began anew during the last 400,000 years. Unfortunately, DNA analysis cannot say where the very grim reaper came from. (Gibbons, Ann; "The Mystery of Humanity's Missing Mutations," Science, 267:35, 1995.) Comment.

Responding to the article in SF#108 on the Lake Victoria cichlids, A. Mebane called our attention to Lake Malawi. While the Lake Victoria cichlids seem to have evolved a profusion of species in a space of about 12,500 years, those cichlids in Lake Malawi may have done the same in only a century or two. T. Goldschmidt advances this evenmore-abbreviated time scale in his book Darwin's Dreampond . In it, he discusses how the water level of Lake Malawi fell more than 120 meters during the 1800s -- an exceptionally dry period in Africa. Today, the Lake is again high and once more host to isolated rocky islands, each with its own unique complement of cichlid fish; each island has species found nowhere else in the lake. Where did all these species come from, considering that their little islands were bone dry just a century ago? Goldschmidt writes: "Cichlids that inhabited these exposed rocks would have suffocated, unless they had already left for wetter climes. Yet today, species that do not exist anywhere else can be found near almost every rocky island. From an orthodox point of view, the most plausible explanation for this is quite surprising: many color forms as well as biological species developed over a period of less than two hundred years." This is certainly explosive speciation -- real biological punctuation! ...

Those favoring the "ancient astronaut" theory assure us that the Wandjina figures are those of alien visitors! The so-called Bradshaw paintings don't fit in the "alien" category but they are so interesting that we choose to reproduce one here. It raises three problems: (1 ) The slim, flowing human figures remind one more of the Tassili rock art found in Africa's Sahara rather than that of the Australian Aborigines; (2 ) The objects at the left are enigmatic and technical-looking; and (3 ) The symbols (? ) at the top are undeciphered. The article at hand from Antiquity does not attempt to interpret the Bradshaw art. Instead, it discusses the social factors that mold the interpretation of the Wandjina and Bradshaw paintings. When Europeans first saw these paintings they were certain that their "advanced style" was far beyond the capabilities of the Aborigines (colonial prejudice). They must, therefore, be the work of "preAborigines." Today's Aborigines will have none of this condescension. They were the original settlers of Australia, and as such they have bona fide land and title claims. Any recognition of "pre-Aborigines" would undercut these claims. (McNiven, Ian ...

(We reproduce only two of Alschuler's graphs.) All four graphs show global "sea changes" commencing about 1988! In other words, collective humanity did reform enough to avert disaster! But how were these atypical human actions initiated and organized? Alschuler suggests "collective psychokinesis." (Alschuler, Alfred S.; "When Prophecy Succeeds: Planetary Visions Near Death and Collective Psychokinesis," American Society for Psychical Research, Journal, 90:292, 1996.) Comment. Alschuler evidently supposes that the Gulf War and massacres in Bosand Africa are merely "ripples" following the 1988 "sea change"!

... Conveyor Belt According to plate tectonics, the earth's continents are being transported -- very slowly -- on a subterranean conveyor belt of sorts. Although plate tectonics, nee continental drift, was ridiculed 50 years ago, it has been very successful in accounting for many geological phenomena. The theory is rarely challenged these days, but there are anomalies out there. "According to the simple plate-tectonic theory, the age of oceanic lithosphere is zero at a spreading oceanic ridge and increases with distance from the ridge. Thus the lithosphere of the central Atlantic, which current palaeogeographical reconstructions assure us began to open no earlier than 120 million years ago, has zero age at the Mid-Atlantic Ridge and, supposedly an age of about 120 million years close to the land masses of Africa and South America at the appropriate latitude. Yet, Bonatti and others (Nature, v. 380, p. 518, 1996) have now recovered samples of 140-million-year-old pelagic limestones not even from the edges of the Atlantic but right in the middle of the ocean, close to the ridge. How can this be possible?" The only explanation (? ) seems to be that this errant chunk of crust got "trapped" in the middle of the Atlantic -- like a misdirected suitcase on an airport conveyor belt.

... flaring up here and there wherever conditions are ripe and the Anthropic Principle reigns. The cosmos as-a -whole might be lurching toward other goals or, perhaps, toward nowhere in particular. Enough philosophy! A team of Australian astronomers, led by J.K . Webb, has been trying to determine if the famous fine-structure constant of physics has really remained constant throughout the 12-billion years or so of the universe's history. The fine-structure constant is dimensionless and almost exactly equal to 1/137. (Why 137? That's another question!) Anyway, the Australians got a good fix on the constant's value 2 billion years ago by measuring the composition of the nuclear waste produced by the Olko natural nuclear reactors in Gabon, Africa. It hasn't changed since then. The spectra of distant quasars 7 billion years old also signaled no change. But more-distant and, therefore, supposedly older, gas clouds have suggested that a slightly smaller fine-structure constant held sway then. No known experimental error can account for this difference. "If confirmed, would Webb's findings eventually be explained by a deeper theory, vindicating physicists' faith in a uniform nature? Or would they mean that we live in a frighteningly arbitrary and variegated cosmos, where huge swathes of space abide by alien principles?"

Saul has analyzed many topographic and geological maps and discovered faint circular terrestrial patterns that have mostly not been described before. These circles measure between 7 and 700 kilometers in diameter and are nearly perfect geometrical figures. The rims of the circles are generally raised and characterized by fracturing and brecciation. These structures can be traced in many geological environments and rocks of all ages. They control to an extraordinary extent regional geology and ore mineralization. To date, some 1,170 circles have been discovered, of which more than half can be visually traced for 360 . Larger circles may exist; one with a diameter of about 2,200 kilometers seems to encircle the southern end of Africa. In the United States, the centers of the circles fall in a northwesterly trend in Arizona; northeasterly in the Appalachians. These circular structures may have been created about 4 billion years ago by intense meteorite bombardment similar to and perhaps identical with the bombardment that marked the surfaces of the moon and other inner planets.

An archeological inventory of the region discloses 212 pillar-circle sites and 251 "tombelles," which are stone cairns or heaps often surrounded by ring-like stone walls. Hundreds of sites with tumuli also dot the area. One of the pillar-circle sites boasts all of 50 individual pillar circles. Some of the pillars are topped with cupules, raised discs, or balls. The fanciest pillars are V- or Y-shaped with crossbars. Archeological exploration of these impressive sites is incomplete. Preliminary dating makes the Senegambian Complex over 1,000 years old.

They are found primarily in four strew fields in Europe, Australia, North America, and Africa. Just about everyone believes that tektites are once-liquid droplets of rock that were solidified in flight. The major question -- often intemperately debated -- is the location of the tektite source. Are they of terrestrial, lunar, cometary, or some other origin? A recent study by Shaw and Wasserberg, using element abundances as a guide, strongly favors a terrestrial origin, with meteor impacts serving as the liquefying and splashing agents. Indeed, specific craters have long been associated with the European and African strew fields. Those who believe that the tektites were splashed all the way from the moon by meteor impacts have not given up yet. One provocative fact stressed in this article is that the ages of the four groups of tektites are 35, 14, 1.3 , and 0.7 million years. Tektites are all quite young!

Amphorae are tall storage vessels that were used widely throughout ancient Europe. These particular amphorae are of Roman manufacture, circa the second century B.C . Much controversy erupted around the finds because Spain and Portugal both claim to have discovered Brazil around 1500 A.D . Roman artifacts were distinctly unwelcome.

... the germ arriving with the rats on ships docking in California during the Gold Rush of 1849. But how could the plague have crossed the mountains and across several radically different ecosystems? One would anticipate finding records of the plague as it made its way into the Southwest. It is true that a less virulent disease, the sylvatic plague, transmitted by similar mechanisms, does exist in the Pacific Coast area; but the bubonic plague does seem highly localized in Arizona and New Mexico. Perhaps another explanation can be discovered in the history of the bubonic plague and the settlement of the Southwest. The plague seems to have commenced in Athens about 430 BC. More or less isolated epidemics followed, but from 1334 to 1351 the disease decimated most of the known world: Europe, Asia, and North Africa. Of course, the American Southwest was not part of the "known world" of 1334-1351. But, coincidentally (? ), this was just about the time that the Hohokam and Anasazi cultures began to decline rapidly in the Southwest. Link this observation to the purported Roman and Hebrew artifacts in the region (SF#43), and one sees the possibility that Old World travellers brought the bubonic plague to the New World well before Columbus landed!
