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.

Bell, in command of the ship Gandara , mused over this question: "Apart from the ones which quite graphically show the lift-off from the water, the other thing that interested me was the wing colouring of brown and yellow, and turquoise. I have noticed during passages around the world how the colours do apparently change, varying from almost trans-lucent purple to a deep navy colour, and wonder how many other colourings of flying-fish wings have been reported. "I think that flying fish are just taken for granted but perhaps if we looked at them more closely, then we may see some really weird and wondeful colours, especially in island areas. What does baffle me, is why, when the wings are only extended during flight, they should be of differing colours. I could understand it if they were a coral-swimming fish where the colours are designed to help them blend into the coral colours and so evade capture, but why the need in flight over crystal clear waters like the Coral Sea?"

Some biologists doubt that springtails should be classified as true insects. In any event, these ancient springtails are considered too specialized to be the ancestors of modern winged insects. The next insects in the fossil record appear suddenly in the Upper Carboniferous (300 million years ago) with fully developed wings. There exists an embarrassing 50-million-year gap between the fossil springtails and the more specialized insects. Evolution requires that this gap be filled with many random experiments at insect construction, including the first attempts at fashioning wings. Whalley admits the gap and the total mystification of paleontologists about how insects and biological flight first developed. Perhaps, he surmises, wings may have been the natural extrapolation of flap-like outgrowths required for body cooling. Random mutations would have added the muscles needed to orient the flaps and move them to improve circulation! (Whalley, Paul; "Derbyshire's Darning Needle," New Scientist, 78:740, 1978.)

Some wing patterns blend into the background, making the butterfly hard to spot; other wings have prominent eyespots that are supposed to deter predators or trick them into striking at the wings instead of the soft, vulnerable body. But some tropi cal butterflies have a double problem; their predators change from dry to wet season. One butterfly, Orsotriena medus, masters this situation by changing wing patterns with the season. In the dry season, it is dark brown and inconspicuous; in the wet season, it switches to black wings with ostentatious eyespots and white bands. (Anonymous; "Cryptic Butterflies," New Scientist, 20, September 13, 1984.) The Asiatic freshwater clam has spread rapidly across North America since its accidental introduction about 50 years ago. In addition to its natural dispersal via its more mobile larvae, the young adult clams have a surprising method of hitchhiking rides on the water currents. Through their siphons they deploy long mucous threads. Water currents pull on these threads just as air currents catch the silken threads of migrating spiders. Given a water current of 10-20 cm/sec, the small clams manufacture and deploy their threads, and off they go downstream.

Perhaps so, but butterfly and moth wings can convey a wide range of "signals." K.B . Sandved, a nature photographer, has also found remarkable renditions of all the letters in the English alphabet (one at a time, of course) on the wings of these insects. In fact, he has accomplished this several times over using different species. He has found all the Arabic numerals, too, as well as ampersands, question marks -- you name it! Although Greek pi and capital omega have turned up, butterflies and maths are clearly trying to impress people who utilize the Roman alphabet. After all, it is difficult enough to evolve an ampersand; generating Chinese characters would strain credulity too much. (Amato, Ivan; "Insect Inscriptions," Science News, 137: 376, 1990.) Comments. Incidentally, of what survival value are these wing symbols? Obviously, the butterflies and moths have not got their act completely together as yet. Words and phrases will come soon, we are certain.

The major argument at the 1984 International Archaeopteryx Conference, in Eichstaett, was about whether Archaeopteryx could fly at all, despite its advanced, aerodynamically shaped feathers. It certainly could not have flown well since it lacks the supracoracoideus pulley-system that acts as a wing elevator in birds. Archaeopteryx could not have raised its wings above the horizontal, making it a poor flier at best. It also lacked the birds' keel bone to which the wing muscles are anchored. But those exquisitely designed feathers, so modern in appearance, tilted the scales. The consensus of the Conference was that Archaeopteryx could indeed fly. (Howgate, Michael E.; "Back to the Trees for Archaeopteryx in Bavaria," Nature, 313:435, 1985.) The really interesting part of the continuing Archaeopteryx saga comes from the recent charge of Fred Hoyle and others that the Archaeopteryx fossil is an outright forgery. Hoyle et al insist that Archaeopteryx could not have flown at all, given its bones and musculature. Archaeopteryx looks like a reptile and was a reptile. As for the modern-looking feathers, they were probably added to the fossil fraudulently. And there do seem to be parts of the fossils on display in London and East Berlin that look highly suspicious.

They permit the geographical dispersal of many species, especially insects. But nature, ever-innovative, has other aeronautical techniques up her sleeve. Consider the tiniest insects that do not possess wings. It is difficult for large animals like ourselves to realize that these tiny creatures are actually prisoners of the so-called "boundary layer" of air hugging all surfaces. The thin boundary layer is stagnant very close to the surface. Any tiny in-sect wishing to take advantage of wind-dispersal to propagate the species farther afield must somehow breach this layer. Some of the scale insects have in their instar phases developed the trick of rearing up on their hind legs, penetrating the boundary layer, and presenting a high-drag surface to the wind. (Many climb along plant surfaces inside the boundary layer to exposed areas before exhibiting this behavior.) The wind plucks them off the plant and carries them off to new territories. The authors think this may be convergent evolutionary strategy for many minute insects. (Washburn, Jan O., and Washburn, Libe; "Active Aerial Dispersal of Minute Wingless Arthropods.....," Science, 223:1088, 1984.) Comment.

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. (Biological Journal of the Linnean Society, 51:359)" An explanation might be that the similarities between the microbats and megabats represent adaptations to similar environmental niches rather than a common ancestry.

Here follows the so-called "Britannia Encounter": "A few weeks later, on July 15 [1991], another Britannia Airways Boeing 737 on a holiday flight from Crete to Gatwick (London) had a similar encounter, this one at 5:45 p.m . Descending 15,000 feet, the copilot caught sight of a "small black lozenge-shaped object" some 500 meters ahead and above. The object was on a collision course, and within two seconds it passed the aircraft's wing at a distance of only 100 meters at less than 10 meters above the wing. The crew felt no impact or wake, and the passengers were not alerted. The pilot assessed the risk of collision as high. When reported to London Air Traffic Control Center, the missile was picked up on radar moving away from the aircraft. It was moving at 100 mph in a southeasterly direction and was no known traffic since it had no transponder to identify it. Another aircraft was warned since the unknown target appeared to turn and head toward it, but the other aircraft saw nothing.

J. Gould, who conducts a monthly column in Natural History reviews the sad history of Goldschmidt and his villification by the scientific establishment. Goldschmidt saw the fossil record as woefully inadequate to justify the assumption of gradual evolution of one form into another. Intermediate forms between separate species do not seem to exist in the fossil record and, if they did, they would probably not have been viable creatures. What good is half a wing? Gould believes that Goldschmidt's "hopeful monster" concept will ultimately be dusted off. The key to "macromutation," Gould feels, is not to be found in major gene reorganizations that might produce a whole wing, feathers included, all at once, but rather in changes in the genes that control the development of embryos. Embryos in their early stages are pretty much alike regardless of species. Gould hopes further that the ruling neo-Darwinians will not be so hostile to new ideas and eventually acknowledge Goldschmidt's important work.

... most people's minds, the strands of DNA are analogous to computer codes that control the manufacture and disposition of proteins. 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? In the April 1994 issue of Discover, J. Cohen and I. Stewart endeavor to set us straight. 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. The connections between the nerve cells comprising the human brain represent much more information than can possibly be encoded in human DNA. A caterpillar has the same DNA as the butterfly it eventually becomes. Ergo, something more than DNA must be involved. [This observation does seem simplistic, because DNA could, in principle, code for metamorphosis.] Like DNA, this "something more" passing from parent to offspring conveys information on the biochemical level. This aspect of heredity has been by-passed as geneticists have focussed on the genes. Cohen and Stewart summarize their views as ...

Under low-angle illumination, the new specimen shows parallel impressions originating from the lower arm of the left "wing." These impressions are "interpreted" as imprints of feather shafts. Thus, the new fossil reinforces the mainstream position that Archaeopteryx really did have feathers and was a link between reptiles and birds. Evolutionists will rest easier now. Two bothersome observations intrude, however. First, although the report on the new specimen states that the question of forgery does not arise here, even though the specimen's tail has been restored to the length deemed by the owner.

It's all just bad press. A. Grajal et al have just discovered that this South American bird utilizes foregut fermentation in digesting its diet of leaves. In fact, the hoatzin is the only bird that has evolved this useful capability. Cows, sloths, and a few other mammals and marsupials evolved foregut fermentation. It is hardly a primitive development! Aside from the smell of fermenting vegetable matter, the hoatzin is a rather remarkable animal - more advanced and well-adapted to its environment than previously thought. Grajal et al remark on all the advantages that foregut fermentation confer on the hoatzin and how remarkable it is that this digestive process can be accomplished in such a small volume (cows have huge stomachs). How did the hoatzin hit upon this mechanism before the mammals did? Why didn't other birds "adopt" it?

There are 57 of them, each about a meter wide and deep, extending over about half a hectare [about 1 acres] They were certainly not used for storage because the level of the groundwater is too high. Nor were they used as dumps; archaeological evidence shows that they were filled in shortly after they were dug, and some have very little in them." It was only when Therkorn mapped the pits did she see that they were not distributed at random. Connecting them as children do with dot-puzzles, she quickly recognized the constellations Taurus (bull), Canis Major (dog), Pegasus (winged horse), and Hercules. The pits were geoglyphs of a new sort, streching for more than 100 meters, sort of Nazca lines in Holland. About 500 meters from the 57-pit array, still another Taurus pattern of pits was uncovered. The mysterious pits didn't contain much, but there were often a few animal bones. The Taurus pits yielded cattle bones; the Pegasus pits, horse bones; etc.; with the bones matching the zodiac animal in each sign. Therkorn surmised that the animal remains represented ritual sacrifices that were probably time-coordinated with specific celestial positions of the real stellar constellations.

... more evidence for redshift quantization has accumulated, scientific resistance to the idea is extreme. We shall now see what all this fuss is about. Tifft first became suspicious that the redshifts of galaxies might be quantized; that is, take on discrete values; when he found that galaxies in the same clusters possessed redshifts that were related to the shapes of the galaxies. The obvious inference was that the redshifts were at least partly dependent upon the galaxy itself rather than entirely upon the galaxy's speed of recession (or distance) from the earth. Then, he found more suggestions of quantization. The redshifts of pairs of galaxies differed by quantized amounts (see figure). More evidence exists for galactic quantization, but this should give the reader a feeling for the conceptual disaster waiting on the wings of astronomy. Can galaxies, like atoms and mole cules, posses quantized states? And do the findings of Tifft and Cocke undermine the redshift-distance relationship? The answer might be YES; and then all of astronomy and our entire view of the universe and its history would have to be reformulated. (Tifft, William G., and Cocke, W.

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. Anyway, the latest fusillade in the Archaeopteryx wars was fired by A. Feduccia in Science. Feduccia demonstrated that the claws of Archaeopteryx are sharp and curved like those of modern arboreal birds and quite unlike either terrestrial birds or theropod dinosaurs. In concluding his long, detailed paper, Feduccia highlights nine additional features of Archaeopteryx that make it look like a modern arboreal bird; i.e ., barbed feathers, asymmetrical flight feathers, etc. V. Morell quotes Feducci as saying, "Paleontologists have tried to turn Archaeopteryx into an earthbound feathered dinosaur. But it's not. It is a bird, a perching bird. And no amount of 'paleobabble' is going to change that." (Feduccia, Alan; "Evidence from Claw Geometry Indicating Arboreal Habits of ...

Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Monarch Migration An Illusion "The epic autumn migration of the eastern monarch butterfly to wintering grounds in Mexico, where millions cluster on trees in semi-dormancy to await spring, has become known as one of the standard 'wonders of nature' in the decade since the Mexican winter clusters were found." There are, however, some flies in this ointment: Monarchs tagged in the north have never been found in the Mexican clusters. Fall-fattened monarchs can store only enough energy for a flight of about 200 miles -- far too short, unless they refuel along the way (no one knows if they do or not); and The monarchs seen in Mexico are almost always in pristine condition and show no wing wear or tattering. A.M . Wenner, University of California at Santa Barbara, thinks that the "appearance" of mass migration reported frequently from many locales may just be due to a curious fall habit of the monarchs. It seems that widely scattered individuals begin to fly into the wind, and the wind concentrates and channels them to local roosts where they spend the winter. In other words, there is no long distance migration at all. (Rensberger, Boyce; Washington Post, September 15, 1986. Cr. J. Judge) From Science Frontiers #49, JAN-FEB 1987 . 1987-2000 William R.

Whatever goes through their "minds," they emerge on the surface in response to vibrations and may be snapped up by several species that know their weakness. Human fishermen know the worms' weakness and "grunt" for them in several ways; say, by drawing a notched stick across the trunk of a small tree to generate vibrations.

Mirage action would elevate the image. By assuming that both an erect and inverted image of the aircraft were projected one above the other, something looking like a missile could be imagined. The black band would have been the doubled image of the wing. (Campbell, Steuart; "Mirage over Edinburgh," Journal of Meteorology, U.K ., 12:308, 1987.) Comment.

Yet, each member of each pair is a different species. Although the pairs are from the same geographical regions, it is not obvious why this astounding mimicry should occur. Here, one cannot invoke the explanation that one species gains an evolutionary advantage by mimicking an unpalatable species, as with mimics of the Monarch Butterfly. That is, there seems to be no evolutionary advantage to looking alike. (Miller, Julie Ann; BioScience, inside front cover, March 1994. Miller's editorial remarks are based upon a later article by H.F . Nijhout, who also supplied the photographs. Nijhout's article explains how butterfly wing patterns may have evolved.) Comment. Cases of remarkable mimicry also occur among geographically separated species. For example, the North American Meadowlarks are dead ringers for the African Yellow-throated Longclaw. "Convergent evolution" names the phenomenon but doesn't tell how or why long chains of random mutations can come up with the same designs where there seems to be no "guidance" by the forces of natural selection.

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.
