The usual list begins with our large brain and bipedality, but these features are shared with dolphins and birds, respectively. Even our peculiar reproductive biology (permanent breasts, continuous sexual receptivity of both sexes, etc.) no longer seem so unique, particularly after reading about the antics of the bonobos (pygmy chimps)! But wait! No other animal, even the other primates, go through adolescence. That time period between puberty and the attainment of adult stature turns out to be something uniquely human. The great puzzle of adolescence, according to B. Bogin, is its evolutionary origin. What possible advantage does adolescence confer on humans in the battle for survival? To the contrary, skipping the teens would appear to be an advantage in the survivability of parents! One guess is that adolescence -- all 8 or so years of it -- is required for the development of the complex social skills needed by adults. (Bogin, Barry; "Why Must I Be a Teenager at All?"

Allen describes how musical theorists have proposed both supernatural and evolutionary explanations for this periodicity, which commenced some 2,500 years ago with the Ancient Greeks. He is not convinced by either class of explanations. Instead, Allen has been beguiled by the long-period tones of environmental cycles: "Now we have knowledge of a constantly operating cyclic factor in our cosmos, scientifically based on a mass of inductive evidence that goes beyond recorded history into the tree-ring records from centuries B.C . For the first time, we are provided with a powerful conditioning factor, if not a determinant, in the creation of music." Here are two statements reflecting Allen's observations on the subject: "After 1590, as a new warm period began in the 100-year cycle, a new Golden Age began in music, as in Science. "In our own day, some composers have been extremely sensitive to cyclic changes. Stravinsky, notably in his return to neoclassicism after 1920, reflected the warm trend."

Were they the bones of pygmies or children of normal-sized tribes? The latter choice was made, and we hear no more on the subject -- at least on the standard academic circuits. But a few reverberations are still detectable elsewhere. V.R . Pilapil, for example, asserts that the disputed Tennessee graves really did contain pygmy remains. Not only that, but he hypothesizes that the pygmies arrived in ancient times from southeast Asia, probably the Philippines, where today's diminutive Aetas live. To support his case, Pilapil recalls B. Fell's examination of the Tennessee skeletal material. Fell noted that: (1 ) The skull brain capacity was equivalent to only about 950 cubic centimeters, about the volume of a non-pygmy 7-yearold; (2 ) The teeth were completely developed and showed severe wear characteristic of mature individuals; and (3 ) The skulls were brachycephalic with projecting jaws. Fell had, in fact, described skulls very much like those of today's adult Philippine Aetas. Another line of evidence adduced by Pilapil involved the traditions of British Columbia tribes, which recognized a tribe of very small people called the Et-nane.

... The scientific "instruments" here are the cooling lava flows. As they solidify from the outside in, a process taking about 2 weeks for a 2meter-thick flow, the lava is magnetized in the direction of the field prevailing at the moment of solidification. We would thus have a 2-week continuous record of the behavior of the earth's field. Ordinarily, we would not expect to see very much change in 2 weeks; even a reversing field is thought to take thousands of years to complete its flip-flop. However, at Steens Mountain, when the field reversed 15.5 million years ago, the lava flows suggest that the field's axis was rotating 3-8 per day -- incredibly fast according to current thinking, in fact a thousand times faster than expected. The conundrum (one might call it a scientific impasse) arises because the flowing electrically conducting fluids that supposedly constitute the earth's dynamo would have to flow at speeds of several kilometers/hour.

The sides of the PMO are perfectly parallel; it is rounded at both ends; the end towards Phobos narrows slightly; the other end seems to have a slight protrusion.

What is most important about these fossilized micro-organisms is that they were found in the Apex chert of Western Australia. The Apex chert is designated Early Archean and assigned an age of 3.465 billion years [Four significant figures!]. It is rare to find any fossils at all in rocks this old, but apparently the Apex chert escaped most of the fossil-destroying metamorphism afflicting most Precambrian formations. Even more remarkable is the diversity of these suspected bacteria. J.W . Schopf reports finding no less than eleven different kinds so far--and our planet was only a few hundred million years old at the time the Apex chert was formed. Schopf's discoveries generate at least three questions: How could life have originated and diversified to such an extent in just a few hundred millions years? Why after such rapid diversification did these microorganisms remain essentially unchanged for the next 3.465 billion years? Such stasis, common in biology, is puzzling. If these microorganisms are really cyanobacteria, they would have released oxygen to the atmosphere. Is the standard assumption that the earth's atmosphere lacked oxygen until 2.2 billion years ago correct? (Schopf, J.

Meaden has summarized this third position in the following paragraph: ". .. we believe that the formation of real crop circles is a rare phenomenon resulting from the motion of a spinning mass of air which Professor Tokio Kikuchi has modelled by computer simulation and calls a nanoburst. This disturbance could involve the breakdown of an up-spinning vortex of the eddy or whirlwind type.

Gamma-ray bursts emanate from highly localized unseen sources. They may last for a few milliseconds or stretch out for several minutes. The energy in the bursts ranges over 26 orders of magnitude. The rise-times of the bursts are so short that the sources can only be a few hundred kilometers across. Before the accompanying map appeared, most scientists thought that the bursters were nearby, probably in the disk of the galaxy, and were due to asteroids being digested by neutron stars or possibly neutron-star quakes. If such were so, the bursters would be concentrated in the plane of the galaxy (the Milky Way), which clearly they are not. Another theory places the bursters in a distant spherical halo about our galaxy. But, in this case, the bursters would have to be much more energetic than astronomers care to contemplate.

Marine biologists have been asking this for years. (SF#20) A.P . Klimley and his colleagues decided to find the answer. First, by direct observation, they determined that the sharks' main purpose was not pro-creation, although some mating did occur. Mainly, the hammerheads just idled away the daylight hours.

This was their feeding time, they swam 10-15 miles to deep waters where they gorged on squid. At daybreak, they were back drifting around Espiritu Santo. Apparently, the mountain was just a place to rest. But how did the hammerheads find their way back so unerringly? Furthermore, by tracking the tagged fish, the researchers found the sharks often precisely followed the same paths in what seemed a featureless ocean. How did they do it? It was quickly ruled out that they were following specific ocean currents or the bottom topography. The hammerheads seemed to possess some sort of unrecognized navigation sense.

Parenti, a coworker of Guidon, has tried to exorcise the geofact argument, which is used wherever tools are "too old", by showing that the 595 pieces of quartz have characteristics quite unlike those created by natural flaking. The doubters are unswayed. You see, despite Parenti's analysis, there remains a minute chance that a falling rock will fracture into pieces, one of which will look human-made. Maybe only one falling rock in 10,000 will fracture "unnaturally;" make it one in 10,000,000; it doesn't matter. Anthropologist D.

In this argument, you see how our title "Darwinism in Archeology" came to be.

At the time these gravels were deposited, volcanic eruptions also laid down lava beds, often tens or scores of feet thick. This occurred a number of times, and together with much erosion since then, have now resulted in table mountains, that is, lava-capped hills where the harder lava has better withstood erosion stresses while surrounding softer material has been swept away. It is under the hard lava beds, in the gold-bearing (auriferous) gravels, where the reported human bones and artifacts were found, not just once or twice, but hundreds of times by miners during the span of time from the 1850s through the 1890s while engaging in mining operations. Findings were spread over a wide geographical area." During the late 1800s, several books and many papers recorded the discoveries. Some of the finds were made by respected scientists of the day. Human skulls were found embedded over ...

... natural or artificial, is an emergent property of collective communication. Human con-sciousness itself may be an epiphenomenon of extraordinary processing power. Although experts prefer to avoid simplistic definitions of intelligence, it seems clear that all intelligence involves the rational manipulation of symbolic information. This is exactly what happens when army ants pass information from individual to individual through the 'writing' and 'reading' of symbols, often in the form of chemical messengers or trail pheromones, which act as stimuli for changing behavior patterns." During its 20-day stationary phase, an army ant colony scatters about 14 foraging raids directed 123 apart. The heavy line indicates the colony's path during the nomadic phase. In the body of his article, Franks describes two remarkable capabilities of an army ant colony: time-keeping and navigation. The outward manisfestation of time-keeping is in the precise timing of the colony's nomadic phase of 15 days (during which larvae are growing) and the 20-day stationary phase (during which pupae develop). The queen's egg-laying also conforms with this schedule. Raids into the rain forest occur in both phases. Perhaps more remarkable is the systematic orientation of the raids in the stationary phase. These raids are separated by an average 123 , as diagrammed. This scattering allows time for new prey to enter the previously raided areas. But how does the colony determine direction in the dense rain forest? Probably from polarized sinlight, thinks Franks. But here we have a problem: each army ant, instead of having multi faceted ...

Here, let us assume that it really does exist, even though we cannot see it. From a new book by I. Asimov (title below), we learn that this remote haze of icy fluff, the Oort Cloud, may really have about 90% of the angular momentum of the entire solar system. It was already sufficiently anomalous to discover that the planets possess fifty times the angular momentum of the much more massive sun. (See ABB3 in The Sun and Solar System Debris.) Astronomers have been attempting for years to explain this 50:1 split. Now, with the Oort Cloud apparently having ten times the angular momentum of the planets, the situation is much worse. According to Asimov, the solar-system angular momentum is split as follows: Oort Cloud 90% All of the planets 9.8 % The sun 0.2 % The total mass of the Oort Cloud is estimated to be roughly that of Saturn. The recent flyby of Halley's Comet created this dilemma. It was discovered that Halley was a chunk containing 140 cubic miles of ice - much larger than anticipated for this "typical" comet. If the estimated 2 trillion comets are, on the average, Halley' ...

... up by a moon of jupiter?The Australasian tektites are glassy blobs found on or near the surface of the ground from the Philippines, through southeast Asia, all the way to Tasmania. Similar but much smaller "microtektites" appear in deapsea de posits in the adjacent oceans. Radiometric and fission-track dating indicate that the tektites solidified about 700,000 years ago. Yet, their geological age, as measured by the age of the terrestrial sediments in which they are found, is only a few thousand years. This great disparity in age engendered a confrontation between geologists and geophysicists. The latter insisted on their 700,000-year figure; the former said "maybe so" but the tektites are still found only in very young, superficial sediments. The point here is that time-of-solidification may not be the same as time-of-fall. At stake is the prevailing theory, now dogmatically proclaimed, that tektites are created when a large asteroid impacts the earth, ejecting molten droplets of rock which shower back to earth as solidified tektites. No one has ever found a suitably large crater ( 200 miles in diameter) assignable to the Australasian tektite strewn field. Nevertheless, the impact model prevails; and the young geological age of the tektites is dismissed as erroneous. A Soviet scientist, E.P . Izokh, has recently proposed a radically different scenario that would produce both the young and old dates. If a moon, or Jupiter, or some similar body, explosively ejected the glassy tektites, embedded in an icy cometary body some 700 ...

... Science Frontiers ONLINE No. 66: Nov-Dec 1989 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Down With The Big Bang We might have concocted the above title, but we didn't ! Rather, J. Maddox, the Editor of Nature, raised that red flag. To make things even worse, he subtitled his editorial: "Apart from being philosophically unacceptable, the Big Bang is an oversimple view of how the Universe began, and it is unlikely to survive the decade ahead." His philosophical objcections to the Big Bang are powerful: "For one thing, the implication is that there was an instant at which time literally began and, so, by extension, an instant before which there was no time. That in turn implies that even if the origin of the Universe may be successfully supposed to lie in the Big Bang, the origin of the Big Bang itself is not susceptible to discussion." The Big Bang, Maddox says, is no more scientific than Biblical creation! The scientific objections involve space, time, the curvature of space. The Big Bang further fails at explaining quasars and the hidden mass of the Universe. Maddox doubts that the Big Bang will survive the new data to be provided by the Hubble telescope.

... says John O'M . Bockris, a physical chemist who has researched cold fusion at Texas A&M University in College Station. (R1) According to Dr. Mallove of M.I .T ., another provocative set of experiments are those at the Los Alamos National Laboratory in New Mexico where Dr. Howard Menlove has repeatedly detected bursts of neutrons, subatomic particles that are a fusion byproduct. (R2) In an interview, [Dr. R.I . Mills] said he had conducted 1,000 experiments with a simple apparatus over the past 18 months and had applied for patents on the process, which differs markedly from the Utah one. He also asserted that he had set a new record for generating heat, saying his apparatus puts out up to 40 times more energy than put in. (R4) (R3) Physicists F.J . Mayer and J.R . Reitz theorize that cold fusion as well as several other riddles of physics can be explained with a hypothetical new particle created through the fleeting union of a proton and electron. (R4) In sum, coldfusion research seems to be rising Phoenix-like after being zapped by most establishment scientists. It will be difficult to overcome the PR campaign orchestrated (by whom?) against cold fusion. However, honest doubts do remain: "It just violates all that we know about nuclear physics," said nuclear chemist J.R . Huizenga. (R1) References R1.

... willing to accept UFOs as valid phenomenon think they are real hardware piloted by extraterrestrials. J. Vallee, a computer scientist and prolific writer on the subject, demurs, and he gives five reasons why: "( 1 ) Unexplained close encounters are far more numerous than required for any physical survey of the earth; (2 ) The humanoid body structure of the alleged 'aliens' is not likely to have originated on another planet and is not biologically adapted to space travel; (3 ) The reported behavior in thousands of abduction reports contradicts the hypothesis of genetic or scientific experimentation on humans by an advanced race; (4 ) The extension of the phenomenon throughout recorded history demonstrates that UFOs are not a contemporary phenomenon; and (5 ) The apparent ability of UFOs to manipulate space and time suggests radically different and richer alternatives." If not extraterrestrial hardware, what are the UFOs? Vallee has three suggestions: (1 ) they are "earth lights" a la P. Devereux; that is, an unappreciated terrestrial phenomenon that impresses mental images on the minds of observers; (2 ) They are artifacts of a "control system" operated by a nonhuman intelligence or, perhaps, a Gaia like manifestation of supernature (of which we are a tiny part) that is trying to modify our behavior; and (3 ) They are apparitions caused by entities ma nipulating space and time; viz,. time travellers from our own past and/or future.
