The presence of chloroplasts in plants, too, may have come about in this way. A case also exists for the alliance of spirochetes with cells to form flagella and cilia. These three "mergers" provided cells with metabolism, photosynthesis, and mobility. Margulis and Sagan obviously do not believe that the "bacterial connection" ended there. They bring their article to a close with an almost poetic manifesto that we now quote in part. The context of the quotation is their assertion that plant and animal evolution would never have taken place unless one life form attacked another and the latter defended itself, all this followed by accomodation and the development of a symbiotic relationship. "Uneasy alliances are at the core of our very many different beings. Individuality, independence -- these are illusions. We live on a flowing pointillist landscape where each dot of paint is also alive. Earth itself is a living habitat, a merger of organisms that have come together, forming new emergent organisms, entirely new kinds of 'individuals' such as green hydras and luminous fish.

Elliott's discovery of a small, stone-covered cist in eastern Washington County, Maine. This cist contained several stone artifacts bearing remarkable symbols, writing, and portrayals of a man and a slain animal. Naturally, mainstream archeologists look askance when amateur archeologists come across such anomalous materials. Happily in this instance, a professional archeologist, J.B . Petersen, Director of the University of Maine's Archaeological Laboratory, took an interest in the site near Grand Lake Stream. After careful study of the site and its artifacts, he has prepared a preliminary report. Petersen's report is accompanied by many photos and sketches made during his excavations. On p. 000 we reproduce a photo of the amulet with its strange epigraphy. Now, we add a sketch of the "elongated hafted ground biface, with human figure." Over 13 inches long, this artifact depicts a trousered, bearded man of European countenance, who is missing one arm and a foot. Petersen asserts that the artifacts have no affinities with American Indian artifacts: rather they have a European flavor. What can one make out of all this? Petersen is only able to state: "Although the site is undoubtedly human-made, its function, antiquity and cultural attribution cannot be precisely specified on the basis of the unique characteristics of both the ...

Many dinosaur fossils have been dug up in Alaska, northern Canada, Siberia, New Zealand, and Antarctica. Not only were some dinosaurs cold-resistant but, seeing many were herbivorous, they were also able to migrate to more temperate climes as the long days of the polar summers waned. The point here is that the dinosaurs as a clan were very adaptable and should have survived severe environmental stress. (Vickers-Rich Patricia, and Rich, Thomas H.; "The Dinosaurs of Winter," Natural History, 100:33, April 1991.) That the polar regions were once covered by lush forests has been underscored by recent discoveries in both polar regions. Stumps of huge trees 45 million years old dot the now-bleak landscape of Axel Heiberg Island far north of the Arctic Circle. In Antarctica, heaps of 3- million-year-old fossil leaves have been found within 400 kilometers of the South Pole. (Francis, Jane E.; "Arctic Eden," Natural History, 100:57, January 1991.

It seems that there were three different species of dolphins, and they were found at the closed ends of underwater passages that were just a bit larger than the living animals themselves. Why did three different species go into the caves at all? Why did they go all the way to the ends of the closed passages, given their excellent echo-location systems? Pertinent here is the discovery of skeletons and recent carcasses of green turtles in similar situations in underwater caves in Indonesia. Turtles lack the dolphins' echo-location equipment, but they are still excellent navigators. (Molnar, R.E .; personal communication, July 2, 1991. Molnar is a scientist at the Queensland Museum.)

W. Smith supposed that because the flamingo has exceptionally long, thin legs that it was difficult for its heart to return blood from its feet. Therefore, by standing on one leg and occasionally switching, the flamingo prevents blood from collecting in its feet. L.J . Los replied with reference to a phenomenon of which we were unaware: "Farm animals are well known for letting sleep be linked to half of their brain at a time. In this way they can maintain a measure of alertness -- even while looking fast asleep. "Flamingos roost upon one of their legs while the other half of their body is in the sleep stage. When the other half of their brain and body earns a rest, they change legs. A leg that is in the sleep stage would not support the bird as a whole." But P. Hardy had the best answer: "Why do flamingos stand on one leg? So ducks only bump into them half the time." (Various authors; "Flamingo File," New Scientist, p. 52, August 17, 1991.)

Waller has visited rock art sites in Europe, North America, and Australia. Standing well back from the painted walls, he claps or creates percussion sounds, and records the echos bouncing back. A casual observer might be tempted to call 911. It turns out, though, that rock art seems to be placed intentionally where echos are not only unusually loud but are also related to the pictured subject matter. Where hooved animals are depicted, one easily evokes echos of a running herd. If a person is drawn, the echos of voices seem to emanate from the picture itself! "At open air sites with paintings, Waller found that echos reverberate on average at a level 8 decibels above the level of the background. At sites without art the average was 3 decibels. In deep caves such as Lascaux and Font-de-Gaume in France, echos in painted chambers produce sound levels of between 23 and 31 decibels. Deep cave walls painted with cats produce sounds from about 1 to 7 decibels. In contrast, surfaces without paint are 'totally flat'." What did the ancient artists have against cats?

Feduccia's cartoon of the bug-catching phase of bird evolution Our alliterative title is apt on two counts: (1 ) Recent research on the famous Archaeopteryx fossils suggest that this animal could indeed fly and was arboreal rather than terrestrial; and (2 ) The paleontologists and ornithologists are still fighting (sometimes emotionally) over how Archaeopteryx fossils should be interpreted. The scientific acrimony centers on whether this ancient bird really evolved from small theropod dinosaurs. Prevailing theory has it that these dinosaurs first evolved feathers to keep warm and then used their feathered "arms" to help capture insects, and so on, with some aimless flapping, to the attainment of true flight. A rival, officially frownedupon theory has it that birds evolved from tree-dwelling reptiles that evolved feathers to break their falls while jumping from branch to branch! [Somehow, neither theory strikes a realistic chord. Why couldn't feathers have evolved solely for the purpose of flight? Answer: because evolutionists cannot countenance purpose in nature. WRC] One reconstruction of Archaeopteryx. There is a remarkable superficial resemblance to the living South American hoatzin. Young hoatzin even sport claws on their wings.

The Copernican Principle, in particular, leads to all sorts of profound prophecies. The Copernican Primciple states that the earth does not occupy a special place in the cosmos. To this we add Darwinism, which asserts that, in the realm of biology, human origin is not special either; i.e ., we enjoy no special place among life forms. Building upon these two general "beliefs," J.R . Gott, III, proceeds to estimate the longevities of various observables, such as the lifetime of a particular species. What follows is a long, highly technical computation of various probabilities, such as the evolution of intelligent life in the universe. All this (and there is a lot of it) leads to the following: "Making only the assumption that you are a random intelligent observer, limits for the total longevity of our species of 0.2 million to 8 million years can be derived at the 95% confidence level. Further consideration indicates that we are unlikely to colonize the Galaxy, and that we are likely to have a higher population than the median for intelligent species." Why won't we colonize the Galaxy? Not because we are not able to, Gott says, but because " ...

Surely an unusual illustration for the archeology section, but the DNA in these mitochondria may upset long-held theories of human migration.

The very idea that bats of any kind could be closely related to humans and apes was quickly dismissed by most zoologists. Flying mammals -- the bats -- evolved only once according to mainstream theory; later the Order Chiroptera (" hand-wings") split into the small, mainly insect-eating microbats and the large, fruit-eating megabats. It was all pretty obvious; how could such complex, specialized animals have evolved twice? But in Science Frontiers, there is ever the "however": "Arnd Schreiber, Doris Erker and Klausdieter Bauer of the University of Heidelberg have looked at the proteins in the blood serum of megabats and primates and found enough in common to suggest a close taxonomic relationship between the two groups.

They are constructed of basalt rocks from ancient lava flows. Artifacts found nearby suggest ages of at least 7,000 years. Younger, but very similar, structures have been found in Central Asia. A. Betts of the University of Sydney has been exploring these walls and attempting to discern their purpose. The best explanation seems to be that the ancient inhabitants of the region drove herds of wild animals into the wide mouths of the kites and then slaughtered them when they were trapped at the corral-like ends.

For high hydrodynamic performance, their bodies must be nicely streamlined. For males, this means that their testicles must be stored internally. But dolphins are very active animals, and their muscles generate considerable heat -- too much heat for sperm to survive without some sort of special cooling system. (Recall that human males with undescended testicles may become sterile.) Since dolphins are obviously procreating, evolution must have come to the dolphins' rescue. Evolution's engineering solution installs heat exchangers in the dolphins' tails and dorsal fins. Blood heated in the vicinity of the testes is pumped through special veins in the tail and dorsal fin, where it is cooled by seawater and then returned to the dolphins' heat-sensitive innards. Female dolphins have similar heat exchangers to cool their uteri. The same article in Discover points out still another remarkable adaptation conferred on dolphins: They do not have to expend a lot of energy in diving to great depths. Below about 70 meters, the water pressure collapses their lungs so that they sink like rocks! Of course, returning to the surface does require some exertion.

These mammals are effectively toothless for predatory purposes. In fact, some marine biologists speculate that they secure their slippery prey by suddenly vacuuming them up by actuating a pumplike tongue. (AR#2 ) But how do the beaked whales find their prey in the first place? With their sonar, of course. But these superbly streamlined animals lack the huge external ears of the sonar-using bats. How do they detect the weak echoes bouncing off fleeing fish? P. Zioupos and J.

At 2.7 grams/cubic centimeter, this bone is 50% denser than the average mammalian bone. "The bone also turned out to have unique chemical properties. It contains 35 per cent calcium by weight -- 13 per cent more than the highest value known previously. Using microscopes, the team showed that the bone is riddled with tiny tunnels. containing highly concentrated minerals."

In the subject article -- his latest paradigm-shaker -- he first reviews the abundant evidence for the existence of large quantities of primordial hydrocarbons deep within the earth and (probably) many other planets throughout the universe. Associated with these hydrocarbons is a "deep, hot, biosphere." By "deep" Gold means 100 kilometers and more. It is this combination of a deep reservoir of hydrocarbons and life forms (probably mostly bacteria) that can account for (among other things): The fact that all helium comes from oil and gas wells The fact that the composition of petroleum is not what one would expect from the decomposition of plants and animals. It is really a mixture of primordial hydrocarbons with some added biochemical by-products; that is, products of that "deep" biosphere. Since carbonaceous material is now known to be common in the solar system (comets, carbonaceous chondrites, etc.), it is likely that many other planets also possess deep stores of hydrocarbons. In these deep, warm, protected, energyrich "wombs," complex biospheres might readily evolve. In Gold's view, deep biospheres may be the rule and surface life the exception!

Flat-topped Monk's Mound at Cahokia, Illinois, rivals the Great Pyramid in volume. A casual observer of this huge earthen structure could only conclude that such immense labor was undertaken for some social imperative, such as worship or sacrifice. Perhaps this was the case in North America, but deep in the South Pacific, just east of Fiji, on the islands of Tonga, native peoples scraped large mounds of earth for what seems to be a frivolous purpose: pigeon-snaring ! But bear in mind that carnivory on these romantic Pacific islands was difficult because large game animals were nonexistent. Captured enemies helped solve the protein problem, but pigeons were much more common, and some species were good-sized and delicious. So much so that eventually only island royalty was allowed to catch and eat them. Pigeon poachers were whipped or executed (and maybe eaten?) In fact, pigeon snaring became a royal sport. To this end, starting at least a thousand years ago, the king's loyal subjects grubbed up the thin island soil and piled it up into high mounds.

The obvious external differences are body hair, the use of language, the method of locomotion, and of course culture. Less well known is the fact that humans are more susceptible to diseases like as cancer and AIDS. Apparently, superficial comparisons of DNAs slough over genetic details that result in major differences in the living animals. Some of the genetic differences between humans and chimps seem to belie that miniscule 1.5 % difference everyone bandies about. To illustrate, humans have only 46 chromosomes, while the great apes all have 48. The 1.5 % figure doesn't hint at this significant difference. Next, take a look at chromosome #9 in humans and the great apes. Chromosome bandings are different enough to raise further suspicions about the 1.5 % figure.

Even though Lake Baikal is only 20-25 million years old, more than 5 kilometers of sediment have accumulated in some spots. These facts are remarkable as fresh-water lakes go, but Baikal also has features usually found only in salty oceans. It seals sport in fresh water 1,000 kilometers from the nearest salt water. (How did they get there?) Even more interesting are Baikal's thermal vents or chimneys that are otherwise restricted to cracks in the earth's crust in the deep oceans. Further enhancing Baikal's marine attributes, deep drilling and seismic profiles have recently discovered the existence of gas hydrates (methane hydrate, for example). Plumes of gas bubbles have also been detected where gas hydrates have been tectonically disturbed. There are even craters on Baikal's deep bottom where gas hydrates have erupted explosively.

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.

The reports have come from scientists, wildlife biologists and elk hunters. Surely, this enough to convince everyone of Bigfoot's reality. Not so! To recognize Bigfoot officially scientists must have a living specimen, a corpse, or at least an good skeleton. They do not.

The utility of these biologically manufactured compasses is obvious. Humans, too, seem to have a magnetic sense, although no one has yet dissected the human head to search for magnetite crystals. Rather, the proof of a magnetic sense comes from direction-finding experiments by Robin R. Baker, in England. In a series of tests involving many subjects, blindfolded humans have been taken far afield and then asked, while still blindfolded, to point "home" and north. The results were surprising. Sense of direction was not lost despite long journeys. Furthermore, tests after removal of the blindfolds showed a marked deterioration of the directionfinding ability. The attachment of magnets and simulated magnets to the subjects proved that the magnets upset di-rection-finding capabilities. The controls with brass "magnets" retained their magnetic sense.

Gold and S. Soter, from Cornell, have championed the theory that earthquake lights, sounds, and precursory animal activities may be due to abiogenic natural gases escaping from deep within the earth. Perhaps some petroleum and natural gas reserves have been created by primordial hydrocarbons working their way outward through the crust rather than by the geochemical alteration of biological materials. Perhaps almost all petroleum is abiogenic -- some Russian scientists hold this view! Western scientists are almost unani-mous that natural gas and oil are bio genic with maybe a touch of upwelling abiogenic hydrocarbons. A major reason given for this stance is that the biogenic theory has been so productive in locating hydrocarbon reserves. This, of course, leaves the earthquake lights and sounds still unexplained. (Anonymous; "Abiogenic Methane? Pro and Con," Geotimes, 25:17, November 1980.) Comment. The moral of this might be that seemingly inconsequential phenomena historically lead to wholesale changes in scientific thinking; viz., the insignificant advance in Mercury's perihelion. Reference.

Not only do these heating elements keep the swordfish eye and brain significantly warmer than the surrounding water but they also keep these organs warm and thus more effective during deep dives into the cold ocean depths. (Carey, Francis G.; "A Brain Heater in the Swordfish," Science, 216:1327, 1982.) (2 ) Plants, it seems, developed light pipes long before humans. Certain plant tissues (etiolated or dark-grown) act as multiple bundles of optical fibers and coherently transfer light over distances of at least 2 cm. Optical tests show that these natural light pipes are much more effective transmitters of light than media that simply scatter light. This unsuspected sophistication of Nature's design may require significant revisions in photobiology, which did not allow for such ingenuity.

Might there be unrecognized influences humans (and possibly other animals) exert knowingly or unknowingly upon inert matter? Many have been the experiments in which humans attempt to affect the swinging of a pendulum, the throws of dice, or the output of a random-number generator. The parapsychologists declare that, YES, humans can exert tiny but statistically significant influences on such devices. But other scientists and the man-in-the-street would really like to see a robust physical effect, not just a bunch of statistics. An ambitious endeavor called the Global Consciousness Project just might be able to produce a more satisfying mind-over-matter effect. This Project is conducted by a group of scientists who maintain a dispersed network of random-number generators (RNGs). A total of 38 RNG stations are presently "listening" for global perturbations in whatever medium carries the supposed human-to-matter influences. The analogy to global weather and seismological stations is appropriate here. On September 9, 2001, the Global Consciousness Project network of RNGs did indeed detect a sort of groaning in the consciousness of the planet's human cargo.

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?" (Policansky, David; "Southernmost Fauna," Science, 264:1002, 1994.) Comment. Those species lacking hemoglobin in their blood are doubly perplexing: (1 ) Zoologists still do not know how sufficient oxygen is transported in these fishes, for what substitutes for normal blood seems inadequate; (2 ) How could they have evolved from hemoglobin-carrying fishes? and (3 ) Why switch from hemoglobin at all when other Antarctic fishes find it perfectly satisfactory?

The hostage hallucinations are compared to those resulting from sensory deprivation, near fatal accidents, and other states of isolation and stress. A common mechanism of action based on entopic phenomena and CNS (central nervous system) excitation and arousal is suggested." In a typical case, an 18-year-old female college student was kidnapped and held for ransom. She was bound, blindfolded, and denied food, water, and toilet facilities. She was periodically threatened with death. She saw dull flashes of light in front of her eyes and small animals and insects on the periphery of her visual field. Becoming hypervigilant, she heard strange sounds and whispers. Hearing loud noises, she thought her captors were coming to kill her.

Two other characteristics are covered in some depth in this article: The discovery that some prehistoric shell middens consist of deep-water shellfish, which must be the result of breath-held diving. This human skill, again unique among primates, is obviously quite ancient. Furthermore, recent experiments suggest that in humans, in addition to seals and ducks, vascular constriction is not limited to the arterioles but extends to the larger arteries, too. This indicates some degree of specialized adaptation to a diving life. Most animals with a sodium deficiency display an active craving for salt which, when satisfied, disappears. In humans, salt intake has little or no relation to the body's needs. Some Inuit tribes avoid salt almost completely, while people in the Western world consume 1520 times the amount needed for health. In other works, a single African species (assuming humans have an African origin) possesses a wildly different scheme of salt management. Humans are also the only primates to regulate body temperature by sweat-cooling, a system profligate in the use of sodium. Proponents of the Aquatic Ape Hypothesis believe that sweat-cooling could not have developed anywhere except near the sea where diets contain considerable salt, in fact much more salt than the body requires.

More recent studies by geologists point to natural origins for the wall, the mortar, and even the inscriptions themselves. The latter may be no more than the burrows of mollusks. This interpretation does make sense because the so-called inscriptions were almost completely covered by the "mortar" -- hardly a good way to convey messages! Also, the inscriptions themselves do not really look regular enough to be man-made. For these and other reasons, the Chatata wall now seems more of a geological curiosity rather than an archeological anomaly.

Together, they have conspired - in a vegetative way - to exterminate the pandas. Why pick on such a cute, lovable animal? Pandas, you see, eat nothing but bamboos; and the bamboos have had enough! The bamboos' strategy is to flower only once in a lifetime. When the appointed time arrives for each species, all plants of the species all over the world flower simultaneously. The various species flower at intervals of 15, 30, 60, or 120 years. (These 15-year multiples and the unknown clocks that determine them are anomalies in themselves.) After a species flowers, all plants die, leaving the fate of the species to a thick carpet of seeds. Until the next flowering, it will extend its domain via vegetative reproduction only. Ten years will pass before the bamboos have grown enough to be a viable pan-da food source. The pandas' only hope is to find a species of bamboo that did not flower.

What good is perfect pitch -- or any kind of musical talent -- in tracking animals or grubbing for tubers? Women vs. men. In another application of magnetic resonance imaging, B. Shaywitz and colleagues at Yale compared the inferior frontal gyrus areas of the brains of men and women engaged in language tests. Specifically, they were being asked whether or not two nonsense words rhymed. Men, they found, use only the left inferior frontal gyrus area, but in women both left and right areas were activated. Conclusion: women, who regularly score better than men in linguistic tests, may acquire this extra capability by harnessing both halves of their brains.

In some lizard species, the released tail is a live thing, thrashing violently, and deluding the predator into thinking he has caught the real animal. Predators, even if not completely fooled by the struggling tail, are diverted into subduing it, giving the lizard time to escape. The detached tails contain their own autonomous nervous system and energy supply. (Dial, Benjamin E., and Fitzpatrick, Lloyd C.; "Lizard Tail Autonomy,..." Science, 219:391, 1983.) Comment. Once again we have a biological system requiring several simultaneous evolutionary developments to be successful. Such complex biological evolution in response to predator-prey feedback is indeed marvelous. From Science Frontiers #26, MAR-APR 1983 . 1983-2000 William R. Corliss ...

Science Frontiers ONLINE No. 101: Sep-Oct 1995 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Dragon fish see red Most fish that make a living in deep, dark ocean waters have eyes that are most sensitive to the blue part of the sun's rays (470-490 nanometers). These are the rays that penetrate to the greatest depths in the sea. This adaptation to blue light means that deepsea fish have evolved visual pigments different from those of surface fish and land animals. Visual pigments are complex chemical compounds, and one must suppose that many, many random mutations took place before deepsea fish were able to manufacture visual pigments different from their relatives living near the surface. (Or did deepsea fish come first?) But there is more to this story. Many dwellers in the black abysses generate their own light. They sport bioluminescent organs so they can be seen by others of their own species and, in addition, illuminate prey for easier capture. In another remarkable example of evolutionary convergence, these bioluminescent organs emit light spectrally matching the eye sensitivity of deepsea fish! So far, though, this story is not any more amazing that many others woven into evolution's fabric. But suppose that a deviant species of deepsea fish upset this cosy status quo by evolving visual pigment and bioluminescent organs operating in a part of the electromagnetic spectrum that other deepsea fish could not perceive. It would be as if this species had radar but the others did not! Well, three genera of dragon fish do ...

Science Frontiers ONLINE No. 44: Mar-Apr 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Evolving on half a wing (and a prayer?)Just about everyone agrees that half a wing is of little use to an animal "straining" to develop the capability of flight. So, how did the marvelously crafted wings of birds, insects, and mammals evolve in infinitesimal steps? Biologists, including Darwin himself, have long puzzled over this. Stephen Jay Gould in a recent article explores a currently favored way of circumventing the negligible additional survival value of half a wing, or even 90% of a wing. This solution (? ) maintains that protowings were not "intended" for flight at all but were developed initially as aerodynamic stabilizers, thermoregulatory systems, sexual attractors or other functions requiring large areas. Gould describes the experiments of Kingsolver and Koehl in which protowings were modelled and tested for their thermoregulatory and flight values. Surprisingly, there was a sharp transition, as the size of the protowing increased, from good thermoregulation but poor flight capability to the reverse -- good flight capability and poor thermoregulation. In other words, a structure developed for one purpose, if enlarged, might be useful for something else! (Gould, Stephen Jay; "Not Necessarily a Wing," Natural History, 94:14, October 1985. See also: Lewin, Roger, "How Does Half a Bird Fly?" Science, 230:530, 1985.) Comment. The work of Kingsolver and Koehl ...

I too have often travelled from Paddington, westwards in my case -- not in frequently in the company of a pigeon, sometimes even two. "It raises fascinating questions. Do they just fly across the line and get the next train back? How many round trips a day do they make? Do they decide in advance how far to travel? Do they study the timetables?" (Howlett, Jack, et al; "Passenger Pigeons," New Scientist, p. 66, September 30, 1995) Comment.
