They therefore enter the trace state more readily. However, once hypnotized, the left-brain-dominated subjects shift into the right-brain mode. It seems that the hypnotic state, with its dream-like quality, altered time sense, etc., is associated with the right brain. Lefthanders, who are always in the right-brain mode, possess 'broadened attention' and resist hypnotic induction more than right-handers.

... 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 that anyone would question the validity of these key transition fossils.

Perturbations by the planets, notably Jupiter, deflected them into the tighter orbits we see today. The problem is that the number of parabolic comets entering the inner solar system from the Oort Cloud of comets (located at the outermost fringes of the solar system) is 100 times too small to account for the existing population of short-period comets.

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.

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, though doubtless of high quality, does not come to grips with the fact that a wing for flight is a highly sophisticated combination of skeleton, feathers, membrane, muscles, nervous system, control system, aerodynamic design, etc. -- most of which have nothing to do with thermoregulation.

Some scientists, however, propose that the iridium layer was instead deposited through widespread volcanic activity. The proponents of an astronomical mechanism should be heartened by a recent paper in Nature, by W.S . Wolbach et al.

The soot layer coincides with the Ir layer, suggesting that the fire was triggered by meteorite impact and began before the ejecta had settled." The composition of the hydrocarbons in the sediments points to the earth's biomass (mainly surface vegetation) as the source of the soot. The total quantity of K-T soot is equivalent to that which would be produced by burning 10% of all present terrestrial plant material.

Briefly, this "fallacy" states that a single type of discrepant observation should not be considered viable if it contradicts a large body of well-established, internally consistent observations. In geology, the Residue Fallacy is employed to dismiss the precursorless polonium halos found by R.V . Gentry, as well as some other radiometric discordances. These scientists seem to have forgotten about the anomalous advance of Mercury's perihelion and a few other obvious residues that ultimately stirred up revolutions in our thinking.

May, at the University of Oxford, complained, "The work is so flawed, I am reluctant to comment." On the other side, a University of Maryland geneticust, S. Benson, comments, "Many people have had such observations, but they have problems getting them published." Our template in this discussion is an article by A.S . Moffat in American Scientist. She says, "The stakes in this dispute are high, indeed. If directed mutations are real, the explanations of evolutionary biology that depend on random events must be thrown out. This would have broad implications. For example, directed mutation would shatter the belief that organisms are related to some ancestor if they share traits. ...

... Pennsylvania, they cite many radiometric dates earlier than 12,000 years. At this Pennsylvania site, the six deepest dates definitely associated with cultural material indicate that humans were here 13,955 to 14,555 years ago. (Adovasio, J.M ., and Carlisle, Ronald C.; "The Meadowcroft Rockshelter," Science, 239:713, 1988.) Kansas River skeletal remains . Using electron-spin resonance to date a piece of a human skull, W. Dort and L.D . Martin affirm a date of 15,400 years before the present. (Bower, B.; "Skeletal Aging of New World Settlers," Science News, 133: 215, 1988.) A Review of the Paleoindian Debate . W. Bray recounts in Nature what happened at a meeting at the Smithsonian last September. Various controversial sites were discussed, such as Calico Hills (200,000 years claimed) and Toca de Esperanca, Brazil (3 ,000,000 years claimed). But, oddly enough, the Meadowcroft Rockshelter and Kansas River data were not mentioned. Chiefly, though, Bray was concerned with what did and what did not constitute generally acceptable proof in archeological dating. That this matter goes beyond idealized science is evident in Bray's quote of anthropologist E. Leach: "Justification in terms of scientific methodology is in part self-deception, for when the figures turn out wrong the true believer will always shuffle the figures; when contrary evidence shows up, he throws doubt upon the credentials of the investigator." ...

... Science Frontiers ONLINE No. 51: May-Jun 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Evolution Through Mergers The overview in Natural History describes how, in theory, the mitochondria in cells were created by bacterial invasion. 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. Without a a life-support system none of us can survive. It is in this light that we are beginning to see the biosphere not only as a continual struggle favoring the most vicious organism but also as an endliess dance of diversifying ...
