About Science Frontiers

Science Frontiers is the bimonthly newsletter providing digests of reports that describe scientific anomalies; that is, those observations and facts that challenge prevailing scientific paradigms. Over 2000 Science Frontiers digests have been published since 1976.

These 2,000+ digests represent only the tip of the proverbial iceberg. The Sourcebook Project, which publishes Science Frontiers, also publishes the Catalog of Anomalies, which delves far more deeply into anomalistics and now extends to sixteen volumes, and covers dozens of disciplines.

Over 14,000 volumes of science journals, including all issues of Nature and Science have been examined for reports on anomalies. In this context, the newsletter Science Frontiers is the appetizer and the Catalog of Anomalies is the main course.

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. 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 ...

"Britain's own scientific knight-errant, Sir Fred Hoyle, has fallen fowl of the palaeontologists. He has flocked together with those who think that the best-ever missing link, the reptile-bird Archaeopteryx, is a convenient fake. Creationists are understandably in high feather about it all. But now, it looks as though they may be left with egg on their faces. ' We first reported on the Archaeopteryx Affair in SF#39. In the present article by Ted Nield, the evolutionists seem to be responding to Hoyle's claim with ridicule and innuendo. Referring to the claim of fossil forgery, which Hoyle based on photos taken with a low-angle flash and EN100 film, Nield wonders why it was published in the British Journal of Photography instead of Nature or Science implying that Hoyle's group didn't dare submit their report to high-class journals! As for the "discovery" of double-struck feathers in the Archaeopteryx fossil, which Hoyle thinks were the result of inexpert forgers, Nield remarks that these were noted by naked as long ago as 1954, and are due to two rows of slightly overlapping feathers with faint "through-printing". And while it is true that the two halves of the fossil studied by the Hoyle group are not perfect positive ...

First, F. Hoyle and C. Wickramasinghe, hardly strangers to these columns, have published Archaeopteryx, The Primordial Bird: A Case of Fossil Forgery. The book elaborates their theory that the Archaeopteryx fossils, much ballyhooed as "proofs" of evolution, are outright forgeries. Second, T. Kemp, a zoologist on the staff of the University Museum, has returned the fire with a mean-minded review. He states that Hoyle and Wickramasinghe "exhibit a staggering ignorance about the nature of fossils and fossilization processes." Kemp concludes his review with an admission that the possibility of forgery should indeed be investigated. "But it should be done by those who actually understand fossils, fossilization and fossil preparation, not by a couple of people who exhibit nothing more than a gargantuan conceit that they are clever enough to solve other people's problems for them when they do not even begin to recognize the nature and complexity of the problems." (Kemp, Tom; "Feather Flights of Fancy," Nature, 324:185, 1986.) Finally, Hoyle and Wickramasinghe reply in a letter to Nature that L.M . Spetner and his colleagues in Israel have analyzed samples of the Archaeopteryx fossil with a scanning electron microscope and X-ray spectroscopy. Results: the rock ...

... Science Frontiers ONLINE No. 46: Jul-Aug 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Archaeopteryx and forgery: another viewpoint We have here what must be considered the evolutionists' reply to the claim of Hoyle and Wickramasinghe that overzealous followers of Darwin deliberately tampered with scientific evidence. "Archaeopteryx lithographica might be regarded as the most important zoological species known, fossil or recent. Its importance lies not in that its transitional nature is unique -- there are many such transitional forms at all taxonomic levels -- but in the fact that it is an obvious and comprehensible example of organic evolution. There have been recent allegations that the feather impressions on Archaeopteryx are a forgery. In this report, proof of authenticity is provided by exactly matching hairline cracks and dendrites on the feathered areas of the opposing slabs, which show the absence of the artificial cement layer into which modern feathers could have been pressed by a forger." (Charig, Alan J., et al; "Archaeopteryx Is Not a Forgery," Science, 232:622, 1986.) Comment. The article itself offers some new evidence, but seems to fall a bit short of the proof promised in the Abstract. Let us wait for a rebuttal by Hoyle & Co. The Abstract's claim that many transitional forms exist at all taxonomic levels certainly does not square with the fossil record described by the punctuated evolutionists! In any event, the fossil record gap between dinosaurs and sophisticatedly feathered Archaeopteryx is still a Marianas Trench. From Science Frontiers # ...

Science Frontiers ONLINE No. 39: May-Jun 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Status of archaeopteryx up in the air!That famous missing link, Archaeopteryx, the flying reptile, continues to make headlines. 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. Conventional paleontologists are, of course, aghast ...

Science Frontiers ONLINE No. 59: Sep-Oct 1988 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects THE NEW ARCHAEOPERYX FOSSIL A new fossil of Archaeopteryx has been found in a private collection, where it was misclassified as a small dinosaur. The specimen was actually found many years ago by an amateur in the Upper Jurassic Solnhofen limestone in Bavaria, in about the same area as the Berlin and Eichstatt Archaeopteryx fossils. 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. In addition, the new Archaeopteryx is 10% larger than the London specimen, 30% larger than the Berlin specimen, and fully twice the size of the Eichstatt specimen. Is there more than one Archaeopteryx species? (Wellnhofer, Peter; "A New Specimen of Archaeopteryx," Science, 240:1790, 1988.

Object: to see if high velocities would deplume the chickens. It seems that Loomis didn't know whether to believe all those stories about tornados tearing the feathers off chickens. Unfortunately, his experiments were inconclusive because the cannon disgorged clouds of feathers plus well-shredded chickens. He recommended that other scientists try lower muzzle velocities! Since those more innocent days, science has accumulated many eye-witness accounts of this incredible phenomenon, including actual photographs that do not appear to have been tampered with in the darkroom. There can no longer be any reasonable doubt, tornados do deplume chickens. (Galway, Joseph G., and Schaefer, Joseph T.; "Fowl Play," Weatherwise, 32:116, 1979.)

The modern study of some really excellent fossil specimens of Archaeopteryx have clouded this issue. The feathers of Archaeopteryx, as preserved in fine limestone, are found to be asymmetrical as required for efficient flight. (Flightless birds have symmetric feathers) The skull is more birdlike than previously thought. In fact, some aspects of Archaeopteryx are like those in "advanced" birds; others are "primitive" There are now three strongly held views among scientists: Archaeopteryx is related to: (1 ) crocodiles; (2 ) theropod dinosaurs; and (3 ) thecodontians (other reptiles).

Even more remarkable is the fact that it has been published in a mainstream scientific journal. In fact, this contribution is full of statements guaranteed to ruffle the feathers of any rationalistic scientist -- and 99.9 % of all scientists are rationalistic. Take, for example, the first sentence of Winkelman's summary: "The correspondences between parapsychological research findings and anthropological reports of magical phenomena reviewed here suggest that magic is associated with an order of the universe which, although investigated empirically within parapsychology, is outside of the understanding of the Western scientific framework." As a consequence of this inflammatory tone of the article, the comments that follow are rather emotional in many instances. A philosopher could write another paper on the character and prejudices of the "scientific belief system" based on these comments alone! Enough of the controversial nature of Winkelman's article; what does it say? Basically, it states that many magic systems; such as sorcery, witchcraft, divination, and faith healing; may have originated and still be sustained by the psi abilities of the practitioners of magic. Psi here includes telepathy, precognition, psychokinesis, etc. The body of the paper reviews the characteristics of magic and the areas "correspondence" with parapsychology. Examples of areas of correspondence: altered states of consciousness, visualization, positive expectation, and belief. ...

Science Frontiers ONLINE No. 36: Nov-Dec 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Is a dog more like a lizard or a chicken?Cladism has been around since at least 1950, when the German entomologist William Hennig began classifying organisms in a new way. "His method was simple: classifications of animals and plants should be based on an assessment of their characters, and only advanced, or derived, characters (synapomorphies) should be used. For example, the character 'possession of feathers' is a synapomorphy shared by all birds that is found in no other organisms; it is used in classification to define Class Aves. All birds have a backbone too, but that is a primitive character for birds because it is seen in all other vertebrates. Primitive characters are of no use in defining a monophyletic group." Early on, cladism ignited many fireworks in the biological community. Today, cladism has become quite respectable. The cladists, however, are now fighting among themselves. One camp draws their "cladograms" (see illustration) using evolutionary theory as a guide. The other side believes that the cladograms should be drawn up first, based only upon actual characters and ignoring the theory of evolution -- let the species fall where they may. When evolutonary theory is omitted in the deliberations, radically different cladograms result. Mammals then seem more closely related to birds than reptiles, for example, as expressed in the illustration. A key connecting character here is mutual warmbloodedness. The shifting of ...

Interestingly enough, the ancient leaders of the Natchez Tribe were called "Suns" and wore feathered headdresses like those of the Plains Indians.

Everyone has experienced both of these ominous-sounding physiological conditions. One can inflict knismesis upon one's self, but gargalesis requires someone else or perhaps a human-like robot (android) to perform the act. All right, so knismesis and gargalesis are really only the two recognized kinds of tickling; but the latter form stimulates several interesting physiological conundrums. First, let's separate the two conditions. Knismesis is very light stimulation of the skin, say by a feather. It rarely produces laughter and can be induced autonomously, by someone else, by a crawling insect, or even by mild electricity. Gargalesis cannot be selfinduced. It consists of heavier pressures applied to specific parts of the body, especially the ribs and arm pits. But the finger probing usually has to be done by someone else. Gargalesis is often very unpleasant but is nevertheless likely to be accompanied by smiles and laughter. In fact, gargalesis can be so disturbing that medieval torturers supposedly tickled some of their victims to death! (A variant of Chinese water torture?) Ticklish areas on the human body. Tickling becomes anomalous only with gargalesis. The questions are: Why does this kind of tickling elicit laughter when it is so unpleasant? Why cannot one tickle one's self this way? At least most people can't . Why does gargalesis exist ...

His article dwells primarily on the physics of the tunnelling phenomenon, which is well verified in the laboratory, but he does not shrink from the biological implications.

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.

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. Also: Anonymous; "Bird with a Sting in Its Tail," New Scientist, p. 10, October 31, 1992.) Comment. As we see from the diagram, homobatrachotoxin possesses a rather complex chemical structure. One wonders how the pitohuis acquired the ability to synthesize it through random mutations. The puzzle deepens when one discovers that homobatrachotoxin is also manufactured by the New World poisondart frogs. Although far-separated taxonomically, both species traveled along the same path of random mutations to achieve this evolutionary convergence.

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.
