The animal is motionless, its senses are diminished; it is very vulnerable. Neither is there any provable biochemical value to sleep. (See BHF31 in Humans II) Yet, a large fraction of an animal's life is spent in this apparently useless and hazardous condition. Why, then, did sleep ever evolve? But with sleep, come dreams, and maybe an answer is to be seen in them. Cats establish long-term memories during sleep. First, it is relevant that an animal's brain (a cat's brain here) seems to be active even when an animal is sleeping deeply but not dreaming. It seems that during an extremely quiet phase of sleep, when researchers thought that nothing much was happening in the [cat's ] brain, groups of cells involved in the formation of new memories signal one another. The signals, discovered only a few years ago, allow cells in many parts of the brain to form lasting links. Then, when a few cells are stimulated during waking hours, the links are activated and an entire memory is recalled. Deep, dreamless sleep has long been thought to be of little value to an animal. Apparently this is not the case. Deep sleep seems to be valuable in memory activation. Score ...

Photoreceptors are sensitive to light but do not produce images. They are found in many groups of animals. Even humans possess photoreceptors besides their eyes; specifically, in the pineal gland and, perhaps, the knees. (SF#116, SF#117) The pineal gland (our "third eye") may have registered photons at some stage in our evolution, but it is now useless or adapted to other purposes. The arthropods, however, still find photoreceptors useful. Crayfish have them on their abdomens, where they initiate an escape response when illuminated. Additionally, the blind shrimp that collect around the glowing deep-sea vents have photoreceptors perched on their backs, presumably to guide them to their prey located around the luminous vents. Recently, the Japanese yellow swallowtail butterflies were discovered to sport photoreceptors on their genitalia.

Furthermore, the fossils now coming to light in the Gobi sandstones are not only abundant but also preserved with great fidelity. For example, at Ukhaa Tolgod, paleontologists are excavating the planet's largest assemblage of fossil vertebrates from the end of the Cretaceous Period (71-75 million years ago). In 1993, about 1,000 fossils representing 20 species of mammals and reptiles were collected. Amazingly, these bones were not disarticulated, scattered about, or severely worn. It was obvious that the Ukhaa Tolgod animals had been very suddenly engulfed by a "tidal wave" of sand. It was a catastrophic event of some sort. But what kind of catastrophes occur on desolate, riverless deserts? Wind is always blowing sand about and dunes creep along in deserts, but healthy animals easily avoid burial. Of course, there are rare, sudden downpours even on the Gobi. But one would expect this rain to be quickly absorbed by the sand. Intrigued by the evidence of unexpected catastrophism in the Gobi, scientists from the American Museum of Natural History first took a look at Nebraska's strange Sand Hills. These Sand Hills stretch for thousands of square miles, reach heights of 400 feet, and are believed to be of aeolian ...

Shahzad Hussain and his colleagues at the Long Island College Hospital in New York gave a questionnaire to 321 allergy sufferers asking them to describe their cats and assess the severity of their symptoms. Those with dark cats were four times as likely to have severe symptoms as people with light-coloured cats. "We were surprised," says Hussain. "So many questions need to be answered."

Cats and some snakes have a vertical shape yet horses and goats have a horizontal one. What is the reason behind the differences and, more importantly, how do the different shapes affect how animals actually see things? The answer for the vertical slit is that it improves an animal's focus in the direction perpendicular to the slit. Thus, cats and snakes hunting close to the ground can better detect their prey over a wide horizontal field. But how about the horses, goats and other grazing animals that must keep their eyes open for predators across a wide horizon? Pupils with horizontal slits would seem to defeat this purpose. Ah, but when they lower their heads to graze, their vertical pupils become horizontal. Simple! (Anonymous; "Eye to Eye," New Scientist, p. 85, December 11, 1999.) Comments. But puzzles remain, otherwise we wouldn't address this subject.

In other words, consciousness is something "special" that makes us more than automatons. Other animals may be automatons, but not us! D. Jones speculates in Nature that if consciousness is a definite, inheritable characteristic, it must have had survival value for it to have evolved. It then follows that consciousness must be en-coded somewhere in our genes. Only a single gene may be enough, for consciousness seems to be an uncomplicated phenomenon. Why? Because just a few simple molecules, such as those found in anesthetics, can disable it completely without affecting other bodily functions. Eventually, Jones continues, the gene (or small number of genes) responsible for consciousness will be identified. Then, we can determine for certain if any of the lower animals are also conscious. We think chimps and dolphins might be, but we're not really sure until we see if they have the necessary genes. In fact, the old-time behaviorists could be right, and all the other animals really are merely automatons. That would definitely make us "special"! Once we have the consciousness genes in our labs, we can introduce them into those other species, such as Rover and Kitty, upon whom we would like to confer the boon of consciousness ...

Despite assurances to the contrary, we must ask if we really know the whole story. These doubts manifest themselves as we see that creatures that are very much alike genetically may be radically different morphologically. In this vein, C. Ventner asserts that all higher vertebrates have roughly the same genes. The animals that result from these re-markedly similar genomes depend upon when specific genes are turned on and off. Ventner says, "We have the same number of genes as cats and dogs, but differently regulated." The genes themselves are supposed to be simply protein factories. Somehow, they are turned on and off (" expressing" themselves) in just the right sequences to help build the target animal. In a far-stretched analogy, the genes are the instruments in an orchestra and the proteins they produce are the notes in a symphony. But where are the symphony's score and its conductor? Very similar orchestras, it seems, can play radically different symphonies given different scores as interpreted by a maestro.

Nevertheless, enough Bigfoot sightings, hearings, and footprints have accumulated in the Rockies for the Denver Post to print a lengthy review of the Bigfoot phenomenon. The article identifies three Colorado hotspots: (1 ) Leadville, where the Little Creek Monster was reported as early as the 1880s; (2 ) the southern San Juan Mountains; and (3 ) Pike National Forest.

(Day, Michael; "Hell on Earth," New Scientist, p. 5, November 20, 1999) 55 million years ago. Ten million years after the dinosaurs may have roasted in a global firestorm, another methane burp may have erupted from the oceans. This burp was slower and did not ignite but was just as lethal. It filled with atmosphere with a highly effective green-house: methane. The result was a pulse of global warming; as seen in a 5-7 -deg C increase in the temperature of ocean-bottom water during that period. Biological evidence for the event occurs in the skeletons of marine animals that litter the ocean sediments laid down in that lethal period. On the land, prior to the methane release, North America was'populated by an odd assortment of unfamiliar mammals; "unfamiliar" to ustoday because they left no descendents. These archaic mammals succumbed to the effects of the sudden global warming and were ultimately replaced by the ancestors of our familiar deer, horses, and canines that streamed across the now-open Bering Land Bridge. Geology, too, provides evidence of this traumatic event. Ocean-bottom cores reveal landslide debris that was probably triggered by the sudden decomposition of great masses of methane hydrate. Seismic probes of the ocean sediments reveal chaotic zones suggesting a violent event. (Kerr, Richard A.; "A Smoking Gun for an Ancient Methane Discharge, ...

Their mechanical devices range from scrapers that physically remove sperm deposited by competing males to plugs that block sperm access in subsequent matings. It is claimed that some male ejaculates introduce not only fertilizing sperm but also "kamikaze" sperm specially designed to hunt down and destroy competing sperm. Well, both sexes can play these games. Some females have ways to eject sperm from undesired males. For example, female feral fowl (hens gone wild!) prefer to mate with dominant males. Often, however, subdominant males force themselves on the females despite resistance and stress calls. The female response to such rapes is differential sperm ejection; that is, they immediately expel the unwanted ejaculate -- at least most of it -- raising the probability that they will be fertilized by the preferred dominant males.

But only 6 inches below the Clovis level, the diggers gingerly brushed the dirt off crude projectile points that were clearly not of Clovis manufacture. This level seems to be about 5,000 years older than the Clovis level according to radiometric dating of charcoal. Skeptics suggest that there has been mixing of the sandy soil and that these early dates are suspect. But thermoluminescent dating has confirmed the 5,000-year time gap. Thorough analyses of the soil with its plant and animal re-mains indicated little if any mixing. D.

Penguins, like most animals, are counter-shaded, dark on the back, light below. When the penguins are swimming, avian predators have difficulty seeing them against the dark sea. Marine predators below tend to lose their white bellies when seen against the bright sky. But when the penguins waddle across the white snow, the avian predators can spot them easily. Unless, of course, the penguins are clever enough to flop over on their backs exposing only their white tummies. Since they perceive aircraft as threats, they topple backwards intentionally.

Perhaps they think more rain is falling or that a mole is burrowing toward them. All we know is that grunting works. In the article under review, English seagulls are reported doing a flat-footed version of an Irish jig to entice their dinner to the surface.

Exact arithmetic, in fact, is an activity of our left brain where language is processed. Our general number sense, though, is sited elsewhere; the parietal lobe, to be specific. Dehaene's experiments with babies demonstrate that, even before they can speak or do exact arithmetic, they can do "approximate arithmetic"; that is, they can distinguish between these two sequences of tones: beep-beep, beep-beep, beep-beep beep-beep, beep-beep, beep-beep-beep. This number sense is apparently hardwired in a specific part of the human brain and the brains of a few other animals that have been tested (monkeys and rats). (Baiter, Michael; "What Makes the Mind Dance and Count?" Science, 292:1635, 2001.) Comment. Superficially, distinguishing between strings of beeps would appear to be a trivial phenomenon. Not so! The general number sense defined by Dehaene would seem to have significant survival value, say, as in assessing threats or hunting opportunities. We can, therefore, conceive a neo-Darwinian evolutionary scenario here.

To acquire raw material, he scraped skin cells from the insides of casts discarded by skiiers who had had broken bones. From this debris, Berliner extracted numerous chemical compounds. As far as anyone could tell, these substances were odorless, so he stored them in open flasks. However, Berliner noticed that when people were working in the lab with the flasks, they were more friendly and relaxed than normal. He could not divine the reason until some months later when he decided to cover the flasks of skin-derived substances. Curiously, the lab workers soon reverted to their usual grumpy selves! What could account for this strange behavior change? Knowing that animals often communicated with one another employing chemicals called pheromones, Berliner suspected that the flasks had been releasing odorless human pheromones. Sure enough, analysis of the skin-derived materials proved him correct. Next: A Look Up the Nose. Biologists have long realized that animal noses actually contain two sensory channels. The first is the familiar olfactory system, which humans also possess. The second channel is the vomeronasal system. In animals, each system has its own separate organs, nerves, and bumps in the brain. The function of the vomeronasal system is pheromone detection.

As As biological observations accumulate, the phenomenon is being found elsewhere in the animal kingdom. The following quotation extends eusociality to the beetles and (in case you wondered) defines "eusociality": "The weevil Austroplatypus incompertus lives in galleries in the heartwood of Eucalyptus trees. Colonies are initiated by solitary fertilized females and, when mature, manifest the three phenomena which characterize eusociality: overlapping generations, cooperative brood care and division into reproductive and sterile (unfertilized) castes. Each colony contains one fertilized and five or so unfertilized adult females, the job of the second group being to deal with predators and to extend and maintain the galleries." (Anonymous; "Sociable Beetles," Nature, 356:111, 1992.) Comment. Eusociality is somewhat of a puzzle in evolutionary theory because one must ask how the phenomenon arises, when it requires some individuals to forswear reproduction and thus give up the chance to pass their genes directly on to progeny. Explanations of such extreme altruism generally state that the nonbreeders are really helping to pass some (or even all) of their genes on by supporting the colony, for they are usually closely related to the breeding female.

Margolis expands on this: "All this suggests some relatively simple, subconscious algorithms which have not, as yet, been explicitly formulated. Research in this direction might well result in new mathematical insights. "It need not be surprising that mathematical insight is more fundamental than language. Even a primitive animal brain is 'wired" to perform exceedingly complex computations essential for survival in an unpredictable environment. The latest 'smart' weapons are rudimentary compared with a humble gnat. Mathematics could be a by-product of these functions.

... of sterile muck, broken once in a while by oasis-like deepsea vents, where weird tube worms thrive amidst clouds of chemosynthetic bacteria. This is a highly misleading portrayal. The situation, in fact, recalls what happened when biologists first released clouds of insecticides in rain forest canopies, thus precipitating a deluge of uncataloged insects into collecting nets waiting below. Now, instead of a mere million species of insects worldwide, entomologists are thinking perhaps 10 million or more. Will the same diversity prevail in the deepsea muck? C.L . Van Dover believes so: "Away from the vents, in the great ocean plains, life is much less dramatic and often scaled down to minute proportions -- threadlike worms, tiny snails, delicate, transparent clams. Yet, the diversity of animals in the cold abyssal muds, it now appears, may rival the celebrated biodiversity of the tropical rain forests." We now know virtually nothing about this fauna, how it survives, and how it evolved. Millions of undescribed species may be awaiting discovery by research submersibles and deep dredging. (Van Dover, Cindy Lee; "Depths of Ignorance," Discover, 14:37, September 1993.) Comment. Preconceptions about life and its talents have often blinded science as to the extent of life's domains. More revelations are sure to come when biologists begin looking at crevicular life -- those multitudinous species prospering in the earth's deep pores and crevices, where they draw energy from the earth's heat and chemicals.

But so far, biologists do not have the slightest notion how such magnetite particles can be turned into a "magnetic sense," which sends the brain information on the direction of the geomagnetic field or, perhaps, draws a magnetic map of sorts. A completely different sort of magnetreceptor is now under investigation, one that humans may also unknowingly possess. It utilizes special photoreceptors that employ an electron-spin resonance process which is modulated by the geomagnetic field. Some of our very sensitive magnetometers use similar phenomena. The biological version of such a receptor would be connected to the brain, as the eye is, and send signals as to the direction of the earth's magnetic field. Sounds interesting, but is there any basis for thinking such a sophisticated gadget could have evolved? It seems that some experiments with newts by J.B . Phillips and S.C . Borland support the idea. The newts were first trained to orient themselves in a certain direction with respect to the geomagnetic field. "When tested under one of four artificial field alignments (magnetic north at geographic north, east, south or west), the newts kept their training directions constant relative to the magnetic rather than the geographic system of reference, but they selected ...

... . 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. Suspecting they might be sensing the geomagnetic field, Klimley began towing a magne tometer behind the boat. Sure enough, the hammerheads were following paths coincident with lines of high magnetic gradient. And Espiritu Santo itself turned out to be a sort of magnetic beacon from which radiated these magnetic "paths" that the hammerheads followed so exactly. Now the question became: How do hammerheads -- and perhaps other animals -- sense such exceedingly small changes in the geomagnetic field? Some birds and mammals do have small particles of magnetite in their bodies, but no one knows how they might be incorporated into a sensory organ. On the other hand, hammerheads and many other sharks are extraordinarily sensitive to electrical fields, responding to fields as low as 10-8 volt/centimeter. Possibly the sharks' forward motion cuts the magnetic lines of force generating an electrical navigational signal. No one knows as yet. And so one mystery leads to another. (Klimley, A. Peter; "Hammerhead City," Natural History, 104:33, October 1995) Comment. Some marine biologists suspect that some deep-water whales and dolphins inadvertently strand themselves while following magnetic "paths" like those ...

Now, an exchange of letters in a creationist journal gives us the opportunity to present a few facts about a giant bone bed of terrestrial vertebrate fossils: the Karoo Supergroup of southern Africa. The point being discussed by the creationists is the source of the estimated 800 billion vertebrate fossils contain ed in the Karoo deposits. Whence this astronomical number of mainly swampdwelling reptiles? And whence the immense volume of sandstones and shale that contains their bones? The Genesis Flood model favored by creationists requires that all 800 billion animals be drowned at the same time and swept into South Africa and fossilized. But, they ask themselves, could the entire earth ever have supported so many swamploving reptiles at the same time? Is the Flood model threatened? (Froede, Carl R., Jr.; "The Karoo and Other Fossil Graveyards: A Further Reply to Mr. Yake," Creation Research Society Quarterly, 32:199, 1996. A response by Bill Yake followed this letter.) Comment. The figure of 800 billion fossils appears in several authoritative works, although concern is expressed about its magnitude and assumptions employed in calculating it. Once thing that is certain is that the Karoo deposits are immense and packed with bones. Even after decades of fossil collecting, bones are still sticking out of the ground. ...

R. MacNeish, a respected archeologist from the Andover Foundation for Archeological Research, has charted a 30,00040,000-year-old paleonotological record of ancient camels, horses, tapirs, and other fauna found while excavating this cave. Intermixed with the animal bones are layers of charcoal (easily carbondated) and hints of human occupation. But don't we all know that humans did not arrive in the New World until 12,000 years ago? Nevertheless, there they are: (1 ) rude human tools; and (2 ) a possible human palm print. Mainstream archeologists are stonewalling again; there must be some mistake! (Appenzeller, Tim; " A High Five from the First New World Settlers?" Science, 255:920, 1992.) Scene: Inside Amerind cells. DNA analyses of the mitochondria present in the cells of North American Indian populations indicate that the Eskimo-Aleut and Nadene populations arrived about 7,500 years ago. The more geographically widespread Amerind population, however, seems to be descended from two separate influxes; the first about 30,000 years ago, the second about 10,000 years ago. D. Wallace, from Emory University, surmises that the sharply defined rise of the Clovis culture, conventionally dated from 12,000 years ago, may have resulted from the second Amerind ...

The babirusa's stomach possesses an extra sac; and the animal often browses on leaves and shoots. It does not, however, chew a cud. The Indonesian babirusa, a pig-like animal with curious tusks and an unusual digestive system (for a pig). Taxonomists are a bit puzzled over the babirusa. They aren't sure whether its closest relatives are modern pigs, peccaries, or hippos. The babirusa's "tusks" pose more questions about its evolution: "The creature's oddest characteristic is the two impressive pairs of curving tusks grown by the males. One pair are simply extended lower canines, but the second are actually upper canines, the sockets of which have rotated, resulting in tusks that grow through the top of the muzzle and emerge from the middle of the animals's face. The effect is bizarre and startling. The males fight with their dagger-like lower canines and probably deflect opponents' blows with the upper set, thus protecting their eyes. Indonesians say the tusks are similar to deer antlers, giving the babirusa its name, which means 'pig deer.'" (Rice, Ellen K.; "The Babirusa: A Most Unusual ...

At least this is where a large, elusive lake monster has been reported for many years. During the summer of 1989, the British Columbia Cryptozoology Club (BCCC) made two expeditions to Okana gan to search out Ogopogo. Several sightings of the animal were made, as well as a video tape. The first sighting, on July 30, was quite detailed, and we quote here from the BCCC report. July 30, 1989. Four sketches of Ogopogo from different vantage points. "The focus of the investigation turned to Summerland, and a particularly good vantage point was located at Peach Orchard Beach, Lower Summerland, on July 30. All four members of the investigating team were stationed at various points on the beachfront when, at 3:55 p.m ., a most extraordinary occurrence took place. A large patch of white water materialized close to a headland at the southern end of the beach, drawing the attention of the BCCC observers. It was about 1,000 feet distant at this point, and it was clear that a large animal was swimming in a northerly direction against the prevailing wind and slight swell. At a distance of about 600 feet, Kirk Sr. was able to see clearly through a Bushnell 40X telescope that this was the classic Ogopogo, with its humps well above the water ...
