... snapping claws of Synalpheus regalis , popularly called snapping shrimp. These diminutive crustaceans live in colonies in the channels of sponges. The individual shrimp in these sponge-sheltered colonies are not all alike. The noise-makers are the "soldier" caste, which wield big "fighting claws." The "workers" that care for the young lack the large claws. All of the young shrimp are produced by a single "queen" shrimp, who is substantially larger than the soldiers and workers. The snapping shrimp social order sounds a lot like that found in bee hives and termite mounds. The snapping shrimp are, in fact, "eusocial" like the social insects. They are the only known eusocial members of the Order Crustacea . Eusociality is considered to be at the apex of animal social organization. What forces have fostered its development in three diverse groups -- insects, mammals (the naked mole-rats), and now the crustaceans? How did the different castes evolve, especially the sterile castes? It must have taken a lot of random mutations to develop such greatly different body forms in a coordinated way such that colonies were continuously viable! Obviously, we have a lot to learn about these snapping shrimp. Are new colonies formed when sexual forms disperse, as with ants and termites; or are there "dispersive morphs" created, as with the naked mole-rats? (See SF#106) (Duffy, J.

The ecosystems clustered around the deep-sea vents and the bacteria found in deep aquifers demonstrate that the sun is not essential to life -- chemical energy does just fine. In fact, the domain of chemosynthetic life has now been extended to a Romanian cave that has apparently been almost completely sealed off from surface influences for 5.5 million years. Air does leak in through tiny cracks, and water partially fills the cave. What is most remarkable in this sunless, sealed ecosystem is its biodiversity: 48 animal species, including 33 brand-new species. The roster includes isopods, a millipede, a centipede, a water scorpion, and a leech. Of course, bacteria and fungi thrive there, too. In contrast to unsealed caves, where insects, bats, and other sources of food filter in from the surface, life in the Romanian cave seems to derive entirely from hydrogen sulfide present in the cave's rocks. This compound is consumed by microorganisms, which are then grazed by cave occupants higher up the food chain. A NASA scientist has called Movile cave a "Mars analog site." And indeed it might be, for Mars has plenty of rocks and subsurface water. (Skinrud, E.; "Romanian Cave Contains Novel Ecosystem," Science News, 149: 405, ...

The infectious agent has been isolated, but it consists only of geneless prions. Somehow, these prions, which are merely protein filaments, get into a sheep's brain and replicate themselves to cause scrapie. With no genetic material of their own, how do the prions multiply? Recent laboratory work suggests that the prions subvert a gene that normally dwells in the brain. With the help of this gene, an endless stream of prions emerges, and the animal is sick. In hamsters, which are employed in laboratory research on scrapie, a gene demarcated PrP has been implicated in scrapie. PrP is present in both healthy and infected hamster brains, but no one knows what its normal function is, if indeed it has one. (Anonymous; "Prion Gene," Scientific American, 253:60, July 1985.)

Theodolite measurements revealed a non-random distribution of the directions of lines attached to look-alike figures. The second test showed a physical relationship of present-day Andean plant and animal figures imagined as silhouettes in dark spots along the Milky Way to figure-lines pointing to the rising and/or setting of the same Andean figure 2000 years ago.

Dumbacher, an ornithologist working in Papua New Guinea, scratched his hand while freeing a hooded pitohui from a collecting net, his first instinct was to suck the wound. This was a bad move, for he immediately experienced a numbing and burning in his mouth. The reason for this, it turned out, was because the skin and feathers of pitohuis are loaded with homobatrachotoxin, a type of poison. This discovery makes the pitohuis the first known poisonous birds. Like many other poisonous animals, the pitohuis also emit a foul odor and advertise their unsavory nature with bright colors. (Dumbacher, John P., et al; "Homobatrachotoxin in the Genus Pitohui : Chemical Defense in Birds?" Science, 258:799, 1992.

Sure, there are also a few creatures that derive their energy by oxidizing the sulfides dissolved in the 400 water gushing forth from deep-sea vents. We will call them "geochemical creatures" to separate them from the "photosynthetic creatures" we are more familiar with. But, in principle at least, there could also be "Carnot creatures", whose metabolisms depend upon temperature differences like almost all human-built engines. Some bizarre animal, such as a meter-long tube worm, could plant one end on a hot rock surface and dangle the other in cold seawater to reject waste heat from its Carnot engine. Since thermodynamic-cycle efficiencies can approach 60% compared with only 10% for photosynthesis, evolution would have been remiss if it had not tried to evolve "Carnot creatures." For, as D. Jones comments below, Carnot creatures would be adaptable to many more habitats in the universe than photosynthetic creatures, which must have a sun with a very specific electromagnetic spectrum.

Now, in a strange turn-about, a creationist writer is using evolutionary theory to infer a very short history for the formation where geologists want a good deal of time. We quote from the conclusion of J.R . Meyer: "If any group of animals were ever going to undergo significant degrees of evolution from parent stock and obtain resultant speciation, surely the Kaibab squirrel would be one of the more likely candidates. Supposedly isolated from their neighbors for hundreds of thousands of generations over a period of at least several million years, and significantly violating virtually every restriction of the Hardy-Weinberg equilibrium for the non-evolving population, these organisms, even by creationist standards, should have undergone significant and detectable changes. In reality all they show are moderate changes, primarily in two coat color characteristics for part of their population. To make things even worse, this species is known to have a highly variable coat-color polymorphism throughout its range. Thus, even the differences displayed appear to be easily accounted for by several mutations and a slight change in gene frequency for one or two loci, all occurring in a limited period of ...

In his early research on the Nazca lines, Aveni noted their strong similarity to the ceque system of 41 imaginary lines radiating outwards from the Inca's Temple of the Sun, at Cuzco -- the "navel" of the Inca universe. ". .. the ceque system was a highly ordered hierarchical cosmographical map, a mnemonic scheme that incorporated virtually all important matters connected with the Inca world view." Could the Nazca lines have been a forerunner of the ceque system? Aveni also noticed that the Nazca lines and geometrical figures were closely related to watercourses. Also, many of the lines definitely functioned as footpaths. It was also apparent that the animal figures, which were laid down much earlier than the line systems, were not related conceptually to the line scheme. Aveni concluded: ". .. whatever the final answer may be to the mystery of the Nazca lines, this much is certain: the pampa is not a confused and meaningless maze of lines, and it was no more intended to be viewed from the air than an Iowa wheat field. The lines and line centers give evidence of a great deal of order, and the well-entrenched concept of radiality offers affinities between the ceque system of Cuzco and the lines on the pampa.

Oil and gas should not be down there in any quantities according to current theory, but that's what they are drilling for. Isn't it futile to fight such a well-established dogma that oil and gas have biological origins and therefore must be looked for only where life once thrived? Not any longer!

The quantities of oil and gas available are hundreds of times those estimated on the basis of biological origins. The so-called "molecular fossils" found in oil and claimed as proof of a biogenic origin are simply biological contaminants, particularly bacteria that feed upon the petroleum. Petroleum is largely saturated with hydrogen, whereas buried biological matter should exhibit a deficiency of hydrogen.

Biological innovation was intense in both instances; both biological explosions burst upon a life-impoverished planet. Many niches were unoccupied. Even so, all existing (and many extinct) phyla arose during the Cambrian explosion and none followed the Permian extinction.

"Adaptive space" was almost empty at the beginning of the Cambrian because multicellular organisms had only begun to evolve; whereas after the Permian extinction the surviving species still represented a diverse group with many adaptations. (Just how the amount of "adaptive space" available was communicated to the "mechanism" doing the innovation is not addressed.)

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."

Duesberg is back in the news again because his iconoclastic views were prominently featured in a TV documen tary entitled "The AIDS Catch" seen in Britain in June. The scientific community was furious, claiming that the documentary was one-sided and selective. Further, it was maintained that Duesberg's arguments have been completely refuted. Briefly, Duesberg believes that AIDS is not an infectious disease because: Too few T-lymphocytes in the peripheral blood are infected to cause the disease; HIV carriers without symptoms exist; and HIV in pure form doesn't seem to induce Aids in humans or animals. Rather, says Duesberg, AIDS is a collection of symptoms arising from such factors as the repeated use of intravenous drugs and malnutrition.

The answer to this mystery may be in the magnetic pulses created by close lightning strikes. Most deaths from lightning are from direct strikes, side flashes, or ground currents. The ground currents kill by passing up one leg and down the other. Cows sheltering under trees are even more susceptible than humans because they contact the ground in four places! People and animals electrocuted by these phenomena bear burn marks and other clues pointing to the cause of death. As for those "mysterious mountain deaths," M. Cherington and colleagues at the Lightning Data Center, Denver, suggest that these unlucky individuals may have been zapped magnetically. Lightning strikes can create electrical currents as high as 100,000 amperes in rocks and soil. These, in turn, create intense magnetic pulses that induce small electrical currents in nearby objects, such as hikers. Although small, these internal currents are sufficient to stop heart action -- without leaving tell-tale signs.

For example, many carvings in Indian temples depict maize, which originated in the New World. A similar situation prevails for the sunflower and a many-seeded New World fruit called "annonas." Sunflowers and maize are also prodigious seed producers, suggesting that these three plants were valued as fertility symbols and may not have been consumed as food.

And how do the termites maintain strict parallelism, especially since they are blind?

The major data source for such population studies is the record of pelt sales rather than actual field observations. Looking beyond such superficial information, researchers have discovered that the quantity of pelts offered for sale by the Indians depends upon the amount of time they can divert to hunting pelts. This, in turn, is affected by the abundance of food animals, such as moose and hares. It is food first and pelts second. Furthermore, when the plants consumed by hares are overbrowsed during periods of dense hare population, they defend themselves by generating resins and other compounds toxic or repellent to hares. Thus, the hare abundance cycle is affected by: (1 ) Plant defenses; (2 ) Indian hunting strategies; and (3 ) The lynx.

Falk discovered that an automobile's engine was limited in power by its radiator's capacity to cool it, he applied this thinking to the human brain. The human brain, like the automobile engine, must be kept cool if it is to function well. It follows that if the brain of an animal is not functioning well, the body that brain controls will not perform well either. Overheated brains, then, are sure roads to extinction in the highly competitive natural world. A couple million years ago, two groups of human precursors were competing for dominance in Africa. The group that won and subsequently evolved into Homo sapiens had, according to Falk, a better brain-cooling system. The evolutionary development that probably led to this advantage was a more extensive network of emissary veins, which permitted better dissipation of heat. This, in turn, allowed the evolution of larger brains and dominance by Homo sapiens. Other anthropologists, how ever doubt that such a minor change in the circulatory system could account for the emergence of modern man. (Shipman, Pat; "Hotheads," Discover, 12:18, April 1991.)

... passage of sperm inseminated by another male. More specifically, their 'kamikaze' hypothesis proposes that deformed mammalian sperm are adapted to fa cilitate the formation and functioning of copulatory plugs." The author of the present paper, A. H. Harcourt, thinks that although some 20% of mammalian sperm, on the average, is abnormal (two heard, no heads, two tails, no tails, coiled tails, etc.) such sperm represents only errors on the assembly line. These abnormal sperm have no special purpose, at least in mammals. (Harcourt, A.H .; "Sperm Competition and the Evolution of Nonfertilizing Sperm in Mammals," Evolution , 45:314, 1991.) Comment. Even if mammals haven't yet developed kamikaze sperm, some animals have; and one must wonder exactly how multipurpose sperm (and ova, too) evolved. For a copulatory plug to be effective, large numbers of mutant sperm with special plugging properties and knowing just where to go, would have to be generated all at once. That would seem to require a lot of chance mutations all at once! The "perfection" problem once again. Reference.

... Invisible Cord," some very remarkable similarities between identical twins reared apart were recounted. A truly fantastic case has now come to light where identical twins (reared together in this case) behave synchronously. "They do every-thing together, scream or sulk if parted and, most uncannily, talk in unison when under stress, speaking the same words in identical voice patterns that create a weird echo effect." Doctors say that Greta and Freda Chaplin are so close that they seem linked by telepathy. Talking or working, they function in unison. Otherwise, they are of normal intelligence and suffer no mental illness. (Anonymous; "British Twins Too Close for Trucker's Comfort," Baltimore Sun, December 8, 1980. p. A3. AP dispatch) Comment. Animals often move in remarkable synchrony; e.g ., flocks of wheeling birds, schooling fish, tropical fireflies, etc. What invisible cord links them?

These tales insist that the birds get so dizzy that they topple over backwards. This makes penguins appear rather stupid, when in truth they are being very smart. 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. Pretty smart of them! (Browyer, Adrian; "White Out," New Scientist, p. 54, December 16, 2000.) Comment. More seriously, an outstanding exception to the countershading rule is Africa's ratel or honey-badger. It is white on top, dark on its belly. But like its cousin, North America's wolverine, the ratel is so strong and fierce that even lions avoid it. It doesn't need camouflage. From Science Frontiers #134, MAR-APR 2001 . 2001 William R.

This is a very delicate situation. The difference between cancer and no cancer is simply too tiny. Given the high frequency of random changes (mutations), we should all have cancer. One implication is that humans (and other animals, too) have come up with some method of preventing or correcting these minor mutations -- otherwise we would have become extinct long ago. No one knows what this mechanism is or why it sometimes fails. (Anonymous; "More Speculation about Oncogenes," Nature, 300;213, 1982.) Reference.
