R. Dawkins' Mount Improbable is never too high to scale with this Darwinistic mechanism -- if given enough time, of course. At times though, we have to wonder if there is not a cog railway or something similar to aid organisms as they ascend this Mount. Such thoughts arose when reading C. Koch's Nature article on neurons and their networks. Neurons are cells with three principal components: the cell body, the axons, and the dendrites. These cells and the networks underlie all of our perceptions, actions, and memories. The ways in which they store and process information has turned out to be much more complex and dynamic than previously supposed. Neural networks are so intricate that Koch was impelled to conclude his review of current research with this paragraph: "As always, we are left with a feeling of awe for the amazing complexity found in nature. Loops within loops across many temporal and spatial scales. And one has the distinct feeling that we have not yet revealed every layer of the onion. Computation can also be implemented biochemically -- raising the fascinating possibility that the elaborate regulatory network of proteins, second messengers and other signalling molecules in the neuron carry out specific computations not only at the cellular but also at the molecular level. ...

Closer study of the announcement reveals that there still remain unreadable snippets of the genome here and there. In fact, the total number of human genes is still in doubt: maybe 30,000, some say 120,000. This wide range of uncertainty does not inspire belief in the accurate readability of this biological blueprint at the present time. Usually left unsaid is the fact that the present blueprint covers only 2-3 % of the territory. That's right, 97-98% of the human genome isn't mapped at all. This uncharted territory is assumed to be "junk" or "nonsense" DNA that plays no role in heredity. Want to bet that this assumption is correct? And don't forget that genes jump around. The genome is really a moving target. Genes also work in concert. It is not one gene coding for one protein, which then has a singular role in creating an operational human being. For example, some 5,692 genes are active in breast-cancer cells. Genes may also have multiple roles. Our present blueprint of the human genome does not display all the mobility and complex interrelationships of the genes. We do know that genes are the blue-prints for the ...

M.H . Hill sketches out in this paper the full extent of the great tract of megalithic remains on the Atlantic coast of Africa near Cape Verde, which he calls the Senegambian Monument Complex because it sits astride both Senegal and Gambia. 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. The functions of this vast array of megalithic sites is unknown, although it is not obviously astronomical.

It is less than satisfying. Be that as it may, scientists are now seeing some strange things happening on the "mesoscopic" scale; i.e ., from a few nanometers to a few millimeters (10-9 to 10-3 meters). This size range lies between the realms of quantum mechanics and macroscopic physics. Maybe these curious phenomena do have a bearing on how life started and whether it is really different from nonlife. Example 1. G. Whitesides, at Harvard, has dumped large quantities of millimeter-size iron balls into a plastic dish and then spun a bar magnet under the ensemble with startling results. The balls swarm around inside the plastic dish as the magnet rotates. At first the swarm is disordered. But after a minute, it breaks up into a set of concentric rotating rings. Within each ring, the balls follow one another along precise tracks, as if hugging the rim of an invisible roulette wheel. Soon the balls in each track are perfectly equidistant. Finally, one ball in each ring comes to a dead stop. The other balls in each track line up behind the leader in a tiny arc, even though the magnet is still whirling away below. Example ...

Looking almost like an 'electric mist', it moved with such speed and ease, as if it were alive. "At the peak of the activity, there appeared to be two central points of spiralling, each about 150 m off either side of the ship about midships. From these points there seemed to be emerging highly confused patterns of spiralling spokes moving in an anticlockwise direction on the port side and clockwise on the starboard side of the ship. It was difficult to estimate accurately how many spokes were present in each circle, but it was thought that there were three or four at any one time, moving very fast and curving to produce what could only be described as a 'whirlpool' effect.

This citadel, called Gran Vilaya, is located about 400 miles northeast of Lima on a 9,000-foot mountain ridge. Savoy said: ". .. the city's buildings ran along the ridge for at least 25 miles. He said the expedition calculated that there were 10,350 stone structures in the defensive network along the ridge and 13,000 other stone buildings in three major city layouts. The stone structures, some measuring 140 feet in length, were built atop terraces that go up the mountain slopes like stairs, he said. He described them as 'complex units of circular buildings with doorways, windows, and niched walls.' The walls, he said, 'soar up as high as a 15-story building." The city was built by the Chachapoyas Indians about 1,000 years ago. The Chacahpoyas empire is dated at 800-1480 AD. The Incas, who finally conquered them, told Spanish explorers that the Chachapoyas were tall, fair-skinned people! (Anonymous; "Ruined City Found in Jungle in Peru," New York Times, July 7, 1985. Cr.

Termite mounds are often mentioned as superoganisms. But here we examine colonies of organisms that are much simpler and much smaller than termites. What entices the anomalist to attend to superorganisms? Here are two of the several questions superorganisms raise. How do superorganisms evolve properties that its constituent individuals do not possess, such as mobility, unique sensors, and even a modicum of intelligence. Since superorganisms do not reproduce as superorganisms, how can natural selection operate on these superorganisms? Salps. Books dealing with the unexplained sometimes include a photograph of a huge marine creature identified as a sea monster. This famous photo is real and so is the monster in it. But this creature is not reptilian; it is really a salp, a colonial tunicate. Tunicates are tiny, primitive marine organisms usually classified as invertebrates. Some species of tunicates have somehow acquired the habit of aggregating in immense numbers to create long, hollow, snake-like tubes called "salpa." Salps may reach lengths of 45 feet, with diameters of 3 feet. No wonder they are falsely identified as sea monsters. Structurally, the tunicates comprising the salp are embedded in a gelatinous wall facing inward. Each possesses a siphon that pumps nutrient-carrying sea water. Working in unison, the tunicates create ...

It now appears that the 'hole' is an uneven one, with 2- to 3-kilometer-thick slices of ozone-poor air sandwiched within layers of only minimal depletion." These new data came from McMurdo Sound, where a series of balloons carrying ozone sensors were released. Ozone depletion seems to be confined to the region 12-20 kilometers altitude and the top of the stratosphere. The overall depletion in this region was 35% at the time the balloons were lofted. However, some zones from 1 to 5 kilometers thick showed depletions as great as 90%. The reason for this stratificaiton is not yet known.

In other words, salt crystals are "natural." "Intelligent design" need not be invoked in explaining their existence. This is OK for salt crystals but can we say the same for biological forms such as proteins and, ultimately, human beings? Are these more complex biological forms also natural; that is, reducible to and explainable by the laws of physics? Human beings certainly seem irreducible; and some proteins are so large and complex that one is unsure that physics is up to the task of explaining these tangled structures consisting many hundreds of atoms. Some of these doubts have been relieved by recent advances in protein chemistry. It appears that the different types of protein folds, which number in the thousands, can be classified and sorted into distinct structural families -- just like the much simpler crystals of salt, quartz, galena, etc fall into orderly classes. The clear implication is that protein folds and, by extension via further research, the protein molecules themselves, are also natural and reducible just like the salt crystals. If proteins are natural, perhaps even more complex biological forms are also, and so on up the complexity ladder to viruses (which often look like crystals through the microscope), bacteria, and ...

Bear in mind when going down the list that most of these features would have been considered absurd only a decade or two ago. The earth's solid inner core, which "floats" inside the liquid core, is not spherical. Rather, it is anisotropic with its axis of symmetry aligned with the earth's axis of rotation. (Ref. 1 below) "The CMB (core-mantle boundary) is the most dramatic discontinuity in the earth's internal structure in terms of the physical and chemical properties as well as the time scale of the processes that take place on either side of it. Its shape, if different from that predicted by the hydrostatic equilibrium theory, may contain information important to our understanding of geodynamic processes in the mantle or the geomagnetic field generated in the outer core." (Ref. 1, and also item #7 below) The earth's magnetic field possesses four lobes which remain fixed relative to the earth's surface, as demonstrated by 300 years of data.

Right now, the Martian atmosphere, surface temperatures, level of ionizing radiation, and noxious soil are inimical to delicate, complex life forms, such as us. But these hostile Martian conditions are easily endured by some bacteria, such as Deinococcus radiodurans . This bacterium, one of the extremophiles, lives in our sewage systems and other unpleasant places. It can survive desiccation, freeze-drying, and high radiation levels. D. radiodurans can do more than survive on Mars. It can begin to detoxify the soil and prepare the way for other pioneer microorganisms.

Leave comfortable earth for a moment and consider the immense, cold clouds of gas and dust swirling between the stars and galaxies. At near-absolute-zero, sunless and waterless, these clouds hardly seem the womb of life. Yet, there may be found the atoms necessary to life -- H, C, O, N, etc -- and in profusion. Collisions of cosmic rays can promote the synthesis of fairly large molecules. We have already detected molecules as complex as formaldehyde in the interstellar medium. But surely the immensely more complicated molecules of biology cannot be synthesized near absolute zero. This may not be true either because at extremely low temperatures the quantum mechanical phenomenon of "tunnelling" becomes important. To achieve molecular synthesis, repulsive barriers must be overcome. The warm temperatures in that terrestrial pond can provide the extra kinetic energy to climb over these barriers. In cold molecular clouds we must look elsewhere. The laws of quantum mechanics state that there is always a very low probability that atoms and molecules can tunnel through repulsive barriers -- no need to climb over them via thermal effects. "Specifically, entire atoms can tunnel through barriers represented by the repulsive forces of other atoms and form complex molecules even though the atoms do not have the energy required by classical chemistry to overcome ...

Not only is this complexity persistent under the attack of the Second Law of Thermodynamics, but it seems to actually increase with time. Do formative or guiding principles exist that science does not take into account? The two articles have very different answers. The creative cosmos. "Most people accept without question that the physical world is coherent and harmonious. Yet according to the traditional scientific picture, the Universe is just a random collection of particles with blind forces acting upon them. There is, then a deep mystery as to how a seemingly directionless assembly of passive entities conspire to produce the elaborate structure and complex organisation found in nature." The author of this introductory paragraph, P. Davies, asks, as we all do, "What is the origin of this creative power?" In groping for an answer, he presents first a common example of "blind" organization: the hexagonal convection cells in a pan of heated water. Using for a stepping stone the cooperative action of atoms in a laser, he leaps to the development of an embryo from a single strand of DNA!

The entire storm may stretch for hundreds of kilometers -- and it is not a simple structure. The latest surprise is that all large electrical storms are bipolar; that is, the rare positive lightning strokes are concentrated at the northeast end of the storm complex, while the negative strokes are everywhere else along a northeast-southwest line. This bipolar structure persists for several hours, and it has been found in all North American storms analyzed so far. This insight into the structure of large electrical storms was provided by magnetic lightning detectors that have now been installed over nearly 75% of the United States. The positive lightning strokes are of longer duration and more liable to start fires than the common negative strokes. But why are they concentrated at one end of the storm complex? R. Orville ventures that in a big mesoscale electrical storm, the prevailing winds blow the positively charged upper portions of the clouds to the northeast, thus establishing bipolarity.

My purpose has been to keep the data base as valuefree as possible.

I will now explain what I mean by "liberating," and why this feature of anomalistics might be scientifically useful. Unless you have been comatose the past several years, you must know that the entire outlook of science is in flux. The words "chaos" and "complexity" are the current buzz words.

Now we add the Mosier Mounds to this file.

The most impressive features are alignments of stacked rocks that hug the contours of the slopes. Although their configuration suggests a battlement, the stone formations weave so sinuously that they cannot be defensive in nature. Some anthropologists suggest that these various lithic structures were used for burials, vision quests, and even the physical conditioning of the young men who were given the job of piling up all the stones! No precise dates are available, but the Mosier Mounds probably predate European contact.

First, they point to the steady drizzle of tiny, organic-rich particles drifting down to earth from cometary debris. These particles, which even carry spacesynthesized amino acids down to the earth's surface, seem likely chemical precursors of life. However, the atmosphere is also a potential source of prebiotic chemicals -- providing energy sources are available.

Let us begin with his abstract: "There are several hints in physics of a domain of external reality transcendent to three-dimensional space and time. This paper calls attention to several of these intimations of a real world beyond the natural order. Examples are the complex state functions in configuration space of quantum mechanics, the singularity at the birth of the universe, the anthropic principle, the role of chance in evolution, and the unaccountable fruit fulness of mathematics for physics. None of these examples touch on the existence or activity of God, but they do suggest that external reality may be much richer than the natural world which it is the task of physics to describe." Pollard then elaborates: Example 1. Quantum mechanics, a mathematical formulation of reality, has been extraordinarily successful in describing and predicting many things in the microscopic world. Pollard notes that quantum mechanics contains no hint of God per se and possesses no numinous quality, but its great complexity and multidimensionality provide evidence for "the reality of the transcendent order in which the natural universe is embedded." Example 2. The singularity at the beginning of the universe. Science is at a loss to explain creation and what happened before. (Pollard assumes that creation occurred like most scientists.) ...

Everit also sets us straight in the matter of computer determinacy. "However, contrary to your basic assumption, most computers (even a home PC) can be forced to behave truly unpredictably. This cannot be done using the random-number generators supplied with the software, as these depend upon some mathematical formula and so are determined in advance, even if they appear to show no pattern. But if the machine has an internal clock readable by the programmer, he can determine the machine's choice depending upon the time required for some complex calculation, which will vary according to such factors as minute voltage variations and the aging of the machine's components. For example, the CDC 3600, on which I learned to program in 1975, had an accessible microsecond clock, and my program to calculate the first five perfect numbers* required about 15 minutes of run time; the last few digits of the exact number of microseconds required to run this program each time varied quite unpredictably. In other words, it was a random number, except perhaps from the standpoint of philosophical determinism, which claims that every event in the entire universe has been determined from the beginning."

The goal of each individual cell was to prosper and proliferate. Competition with other cells, including those of the same species, was intense. Altruism did not exist. The most successful species were those that were tough and aggressive. Nevertheless, as the Cambrian began, some single cells suppressed their mutual antagonisms and formed partnerships. Thus were born the first metazoans -- the multicellular species. The road was now open to the evolution of what we term "higher" life forms. But before really complex organisms could evolve, the selfish, aggressive characteristics inherited from the ancestral single-cell species had to be tamed. Unfortunately, some of the controls that evolved -- and which we have inherited -- do not always work. Conversely, they sometimes work too well. J.M . Saul has described how the appearance of cancer in complex multicellular organisms may be the consequence of the failure of biochemical controls evolved to curb cell aggression: "Such failure may be seen as reversion to ancestral cellular behavior, or as failure of a cell with a monocellular heritage to perform metazoan tasks for which it was not originally designed. In such instances, the resultant types of wild and indiscriminate proliferation and variation would resemble pathologies classified as 'cancer.'" Furthermore, Saul speculates, overcontrol ...

Perhaps our current fascination with computers has fostered this narrow view of heredity. Do our genes really contain all the information necessary for constructing human bodies?

The arguments against the "genes-are-everything" paradigm are long and complex, but Cohen and Stewart also provide some simple, possibly simplistic observations supporting a much broader view of genetics. Mammalian DNA contains fewer bases than amphibian DNA, even though mammals are considered more complex and "advanced." The implication is that "DNA-as-a -message" must be a flawed metaphor. Wings have been invented at least four times by divergent classes (pterosaurs, insects, birds, bats); and it is very unlikely that there is a common DNA sequence that specifies how to manufacture a wing.

Over 100 reports exist where echoes of radio transmissions were received seconds later at the original transmitting station. Since light travels 186,000 miles per second, any simple radio-wave reflector would have to be well beyond the moon's orbit. A wide variety of natural phenomena (interplanetary matter) and even artificial devices (alien space probes) have been postulated to explain the long delays. Muldrew's article is first of all an excellent summary of the long and fascinating history of this effect. His bibliography is extensive and apparently nearly complete. Muldrew next examines the various ionospheric mechanisms that might cause long delays. The ionosphere is a complex structure with ducts in which radio signals can get trapped. Delays of a second or so might be due to such trapping but the longer delays require some other explanation. Muldrew favors a rather complex interaction between signals from separate transmitters that (theoretically at least) can create a long-lived electrostatic wave that travels in the ionosphere -- a sort of natural memory device. The coded signals could then be read out much later when the proper natural conditions developed. Delays of up to 40 seconds might be possible with this "ionospheric memory."

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. (Morowitz, Harold J.; "Do Bacteria Think?" Psychology Today, 15:10, February 1981.) Comment. This ancient controversy about determinism has been revived as: (1 ) Simple life forms have been found to be not-so-simple; (2 ) All life seems unified by a single (or small number of) genetic codes; and (3 ) " ...

... "Representations of a hare or rabbit on the moon are found in the art of ancient China and in Pre-Columbian Mexico. Mythologies of both areas also place a rabbit on the moon. Although such linkage might appear to be arbitrary, a comparison of the visible surface of the full moon with the silhouette of a rabbit does reveal a degree of congruence. Not only the distinctive ears of the rabbit but also other features appear to be delineated on the moon's surface." Could the parallelisms in art and myth in China and ancient Mexico not be simple coincidence helped along by the rabbit-like visage of the full moon? Wicke's article deals with this possibility in depth, but he discounts it in the following paragraph: "Moreover, if one delves into the complexities of the association of hare and moon as manifest in mythology as well as in graphic imagery, correspondence between those of China and Mexico seem both too complex and too arbitrary to have been arrived at independently. Indeed, the mythology and imagery of the hare on the moon in Mesoamerica would seem to derive from Transpacific sources." (Wicke, Charles R.; "The Mesoamerican Rabbit in the Moon: An Influence from Han China?" Archaeoastronomy, 7:46, 1984.) Comment.

Initially these consisted of two circles joined by a straight channel of flattened corn, with extra features such as rectangles or semicircular rings. There have now been about 20 of these. The latest have quadrupled the length to about 150 yards and consist of complex arrangements of up to nine plain or ringed circles with new features, like 'keys,' which can be seen in photographs of the Alton Barnes pictogram. Nothing like this was observed in previous years." (Wingfield, George; "Ever-Increasing Circles of Bewilderment," London Independent, August 4, 1990. Cr. T. Good via L. Farish) ...

... The only one we observe is the one offering just the right combination of properties for evolving life and, especially, humankind. If this or that physical constant had been a tad different, humans would not have evolved. Even though humans obviously did evolve, it was all purposeless -- just the way atoms and molecules happened to combine. This outlook fits right in with Darwinism, for almost all Darwinists also see evolution as purposeless. It was blind chance that gave us the capabilities to build aircraft and tunnel into opposite sides of a mountain and meet in the middle. Moliner is highly skeptical that such amazing, "cooperative, adaptive" talents could have come about in an unbiased, purposeless universe. Suppose, he asks, vipers were philosophically minded. They might look at their marvelously complex fangs with the canals inside, a nearby poison gland, a poison storage reservoir with special ducts leading to the fangs, a fang-erection mechanism, a set of muscles to squeeze the poison reservoir, and a nervous system to control the whole system, and conclude that there must be an Ophidian Principle at work in the universe for vipers to end up with all these neatly interconnected biological components! Using the foregoing musings for a launch pad, Moliner assails Darwinism head on, employing the "what-good-is half-a -wing" and "complexity" arguments: "It is easy to visualise how random mutations followed by natural selection could lead to the right curvature of the fangs for better grasping of prey. But what would have been the selective advantage of the ...

... Color Vision The eyes of most mammals incorporate two types of color-sensitive cones; one for seeing blue light, the other for green light. Such mammals have bichromatic vision and discern colors rather well. Humans and the other primates are blessed with trichromatic vision, for their eyes have cones that register red light. Does this indicate evolution superiority? Hardly, birds possess five types of color-sensitive cones that sense two additional parts of the spectrum. How and why these enhancements in color vision occurred are not well-understood. Nor do we know why they were restricted to mammals and birds; although it is easy to fabricate several survival-of-the-fittest scenarios. The "how" part of the mystery is particularly hard to grasp in neo-Darwinian terms because the complex pigments that confer spectral sensitivity upon the cones represent remarkable, complex chemical syntheses. Also mysterious is the apparent loss of color vision in 14 species of toothed whales and seals. (Only 14 species were examined; there may be more.) These particular whales and seals lack the blue-sensitive cones, even though they are descended from mammals with bichromatic vision (hippos and otters, respectively). This deficiency is doubly perplexing: Sensitivity to blue light is highly desirable in the ocean environment because it is blue light that penetrates seawater well. The loss occurred in two mammalian lineages not particularly closely related on the evolution charts. In other words, they were probably not random, unlucky mutations; rather, something more profound. Neo-Darwinists are quick to explain that these afflicted species ...

Science Frontiers ONLINE No. 47: Sep-Oct 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Earth's womb Three recent items indicate that scientists are now recognizing how the earth's crust is tailor-made for biochemical reactions of great variety and complexity. First, E.G . Nisbet explains how subsurface hydrothermal systems are ideal places to make biochemical products, particularly in the light of the discovery that RNA molecules can extrude introns and then behave like enzymes. "The most likely site for the inorgan ic construction or an RNA chain, which would have occurred in the Archaean, is in a hydrothermal system. Only in such a setting would the necessary basic components (CH4 , NH3 , and phosphates) be freely available. Suitable pH (fluctuating around 8) and temperatures around 40 C are characteristic of hydrothermal systems on land. Furthermore, altered lavas in the zeolite metamorphic facies, which are rich in zeolites, clays and heavy metal sulphides, would provide catalytic surfaces, pores and molecular sieves in which RNA molecules could be assembled and contained. If the RNA could then replicate with the aid of ribozymes and without proteins, the chance of creating life becomes not impossible but merely wildly unlikely." The article concludes with a statement that self-replicating molecules synthesized in hydrothermal systems would be pre-adapted to "life" in the open ocean if they "learned" to surround themselves with bags of lipids. (Bag of lipids = a membrane.) (Nisbet, E.G .; " ...
