An oft-discussed question is: Why don't the slaves rebel or at least try to escape back to their home nest? There seems to be no evolutionary advantage in remaining in passive slavery promoting the fortunes of the slave-makers. The opportunities to run off and rebel are never taken. It would seem that slave-ant passivity is a marked disadvantage that has slipped through evolution's net. Regardless of the reason, an imbalance exists. (Gladstone, Douglas E.; "Why There Are No Ant Slave Rebellions," American Naturalist, 117:779, 1981.) Comment. Perhaps evolution just hasn't had time to redress the situation and even now is preparing clever mutations to rescue the slave ants; i.e ., improve their fitness.

The primate-like eye-brain system of the fruit bats suggests two possibilities: 1. Primitive bats first developed flight and then the fruit bats developed their primate-like eye-brain systems through "convergent evolution"; or 2. The fruit bats inherited their eye-brain system from closely re lated primates and then developed flight through "convergent evolu tion." R.D . Martin, a physical anthropologist and author of this article, has reviewed the morphological characteristics of the fruit bats and primates. On this basis, he doubts that the fruit bats are pri-mates. Furthermore, molecular studies are also negative. Therefore, possibility #1 above is the more likely one. (Martin, R.D .; "Are Fruit Bats Primates?" Nature, 320:482, 1986.) Comment. In either case, #1 or #2 , we must acknowledge convergent evolution and the likelihood that some subroutine in the genetic code repeats itself in divergent species.

The universe of voles -- small, mouse-like rodents -- is one of odor. They communicate with one another and navigate through their world of grass and vegetation by laying down trails of scent-laden urine. The world of kestrels -- eaters of voles -- is one of sight. Now, voles are hard to see in the grass far below a hunting kestrel, but evolution has come to the aid of the kestrels by giving them the capability to see in the ultra-violet portion of the spectrum. Can it be only coincidence that the urine trails of the voles happen to absorb ultra-violet light strongly? Kestrels can see these trails as dark streaks in the grass below and zero in on their prey. Finnish scientists, led by E. Korpimaki at the University of Turku, have demonstrated the above ultraviolet connection by somehow acquiring enough vole urine to lay out artificial trails in voleless areas. Sure enough, hunting kestrels were attracted to the experimental site and searched and searched the artificial vole highways -- volelessly.

Ob-viously the Principle of Superposition is contradicted in such situations. Two possible explanations exist for these inverted strata: (1 ) The dating of the rocks is incorrect; or (2 ) Geological forces somehow slid the older rocks over the top of the younger rocks. Few mainstream scientists give any thought to the first possibility because it implies that evolution did not proceed as presently envisioned. (Rocks are often dated by their fossil contents.) So, geologists are left with the problems of sliding great masses of rock over rough surfaces for great distances. Sketch of the forces acting upon a thrust block being pushed by a wedge-shaped driver Low-angle thrust faulting is not a trivial geological process. To illustrate, the Lewis Overthrust in Montana and adjacent Canada involves the shoving of a block of old strata hundreds of feet thick, hundreds of miles long, over younger rock for a distance of possibly 50 miles. In contemplating such overthrusts, one immediately comes face to face with the Mechanical Paradox. Brief-ly, given the coefficient of friction between the layers of rock, the weight of the thrust block, and the mechanical strength of the rock being pushed, it can be shown that pushing the thrust block at the rear edge will crush it long before it begins to slide.

Vrba, of the Transvaal Museum, in Pretoria, stated: "If we eventually are able to establish a good time resolution with the continental record, I expect to be able to discern synchronous pulses of evolution that involve many groups of fauna and flora. Many different lineages in the biota will respond by synchronous waves of speciation and extinction to global temperature extremes and attendant environmental changes. This is my starting hypothesis." Vrba was speaking mainly about the last 25 million years, a mere flash in geological time. For this brief period, the Deep Sea Drilling Program has provided geologists with a detailed and continuous record of climate changes as they were recorded in deep-sea sediments. By contrast, the faunal history of the continents is rather fragmentary, making it rather difficult to match up pulsations of climate with pulsations of life. Even so, scientists have found rather strong correlations between climatary change and biological speciation and extinction at 15, 5, and 2.4 million years ago. (Lewin, Roger; "The Paleoclimatic Magic Numbers Game," Science, 226:154, 1984.) Comment. Note that this is just the period our ancestors seemed to be evolving rapidly. Also interesting is the general agreement between Vrba's statement about the driving forces behind evolution and McClintock's conclusion quoted earlier ...

Unfortunately these four satellites are so small that they could not have accommodated any reasonable energy source capable of causing the observed crustal evolution.

Toward the close of the article, Dixon asks why humans (and other animals, too) have evolved an immunological system sensitive to stress. Evolutionists can always find some sort of justification in Darwinian terms, and Dixon's is rather ingenious. Suppose a primitive human was attacked by a saber-toothed tiger (what else?). If the human survived, his immunological system would immediately go into high gear to clean up the wounds and repel invading germs. The trouble is that a revved-up immunological system (especially the white blood cells) can go too far and chomp up healthy tissue, too. However, evolution has constructed animals such that stress (saber-toothed tigers are stressful!) suppresses the immunological system to restrict the consumption of healthy tissues. While this short-term damper on immunological activity may have been useful to primitive humans, the stresses on modern man are less intense and long-term. We are sick a lot, particularly with cancer, because evolution has not yet adjusted or finetuned us to the new environment. (Dixon, Bernard; "Dangerous Thoughts," Science 86, 7:63, April 1986.)

Because there seems no need for these inserted jumbles of genetic information, they are characterized as "nonsense." But evolutionists insist that this nonsense must have some survival value or it wouldn't be there! Present speculation is that the nonsense segments separate mini-genes that contain the blueprints for assembling well-defined parts of proteins that possess specific functions. To illustrate, the main part of the immunoglobulin molecule has four functional parts (one for interacting with cell membranes, another that functions as a hinge, and so on). Lo and behold, the immunoglobulin gene consists of four mini-genes separated by three segments of nonsense. The suspicion is that the evolution of higher life forms has been accelerated by keeping these prefabricated, functionally oriented mini-genes apart and shuffling them as integral units. The shuffling of entire functional elements rather than smaller bits and pieces of genetic information might speed up organic evolution. (Lewin, Roger; "Why Split Genes?"

The demise or extintcion of the Ediacarans led Gould, the author of this far-ranging article, to the influence of extinctions on life in general -- a hot topic these days. Gould stated that with natural selection operating, one would expect continual "improvement" in life forms, but that this had not happened. "I regard the failure to find a clear 'vector of progress' in life's history as the most puzzling fact of the fossil record. But I also believe that we are now on the verge of a solution, thanks to a better understanding of evolution in both normal and catastrophic times. We need a twotiered explanation for patterns (or non-patterns) in the history of life." The first tier of explanation involves the theory of punctuated equilibrium, as championed by Gould and Eldredge. Gould says he once thought that punctuated evolution would be sufficient to explain all of life's development, but that now a second tier seemed required; namely, a general theory of mass extinction or what catastrophism does to life and its development.

But, ask evolutionists, how did this poison apparatus get on the hind legs? The supposed ancestors of the platypus, the reptiles, modified their salivary glands for venom delivery. How did the platypusses break from this evolutionary mold and innovate? It's not consistent with the text! The fossil record reveals that a platypus-like creature lived long before the Age of Mammals. These early platypusses had teeth in the adult phase, whereas their modern relatives replace their baby teeth with horny plates -- another innovation. Therefore, far from being a hodgepodge of parts left over from bird and reptile evolution, the platypus has actually pioneered several zoological features. Very curious is the fact that the platypus is in many ways like the beaver -- a very, very distant relative both in distance and position on the Tree of Life. Both platypus and beaver are furry, aquatic creatures with webbed feet and a large, flat tail. We have saved the strangest part for the end!

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 a few lines in a cladogram may seem trivial to the nonbiologist, but saying that man is more closely related to a chicken than a lizard is pretty controversial stuff to the conservative evolutionist.

Tipler's thoughts evoked a richly provocative group of letters, some of which were published in the March 1982 issue of Physics Today along with a closely related article by Ornstein. Ornstein tackled the problem of estimating the probability that intelligent life would evolve on other planets from a biologist's perspective. Whereas some physical scientists have set this probability at about 1.0 , Ornstein inclines toward 10-9 , believing that intelligent life is probably unique to the earth. But concludes Ornstein, the 15 separate developments of eyes among disparate terrestrial organisms may infer some unrecognized directing factor in evolution that would force him to revise his estimate upwards drastically. On the other hand, those 15 eyes might indicate a common, but still undiscovered, eye-possessing ancestor far back along evolution's track. The fossil record might be mute on this matter because eyes are soft tissues that are rarely preserved or perhaps because many eyes were jettisoned because the organisms didn't need them, as cave dwellers are wont to do with surprising rapidity.

It turns out in the end that a sweeping interpretation of this "Tiny Mystery" is called into question, but the mystery itself, like the smile on the Cheshire cat, remains. The "Tiny Mystery" is the existence of radiohalos from polonium-210, -214, and -218 in some biotites (micas), sans any detectable precursory uranium or halos thereof. Since the half-lives of the polonium isotopes are 138.4 days, 0.000164 second, and 3.04 minutes, respectively, it is certainly perplexing how the polonium halos got where they are! According to geological thinking, the igneous rocks containing the biotites must have been molten for a good deal longer than 138 days, thus destroying halos of short-lived isotopes. R.V .

Does this indicate evolution superiority? Hardly, birds possess five types of color-sensitive cones that sense two additional parts of the spectrum.

Nor do we know why they were restricted to mammals and birds; although it is easy to fabricate several survival-of-the-fittest scenarios.

Also mysterious is the apparent loss of color vision in 14 species of toothed whales and seals. (Only 14 species were examined; there may be more.) These particular whales and seals lack the blue-sensitive cones, even though they are descended from mammals with bichromatic vision (hippos and otters, respectively).

The gaps in the fossil record, which imply a frequent lack of transitional forms from one species to another. As Stanley asserts repeatedly in his interview, the fossil record is actually quite good in many places, despite the long-voiced claims of the gradualists that transitional forms do not exist merely because of the deplorable state of the fossil record.

As the pendulum bob swings farther away from its rest position, the restoring force becomes nonlinear; i.e ., not proportional to the displacement. At some combination of displacement and driving frequency, a region of chaos may develop, in which theory is powerless to tell what is going to happen next. "It is not just the behavior of pendulums that has sprung this surprise. Systems as diverse as simple electrical circuits, dynamos, lasers, chemical reactions and heart cells behave in an analogous way and the implications extend far beyond these examples -- to matters such as weather forecasting, populations of biological species, physiological and psychiatric medicine, economic forecasting and perhaps the evolution of society."

The paper begins with the well-worn peppered-moth story; but Callaghan quickly dismisses this, as the creationists do, as merely an example of variation within a species.

In the latest issue, a medical doctor reviews the hoary ontogeny-recapitulates-phylogeny hypothesis. As classically stated by evolutionists, the human embryo passes through stages in which it looks like creatures that preceded it in evolution. The doctor, G.R . Culp, remarks that although evolutionists maintain that reputable scientists no longer employ this argument as evidence for evolution, the "recapitulation" claim is still being made in some classrooms and even during some of the recent creationist-evolutionist debates. In some humans such as the "hairy child" sketched above, the lanugo or natal hair persists beyond the womb. Drawing from Incredible Life. Culp then shows why the recapitulation claim failed in five stages in the development of the human embryo. A rich lode of anomalies exists here: cells migrate purposefully, mysterious struc-tures grow and then disappear; it is a kaleidoscope of changing structures and processes. Take, for example, the "hair stage": "The embryo is covered with very fine hair at about the seventh month of development of the embryo. The evolutionist claims that this is evidence that men came from hairy mammals like the apes. However, these hairs are unlike the hair found on apes, as they are very small in diam eter and always soft and unpigmented. This hair disappears from the ...

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.

"Important new discoveries on the properties of the early earth and atmosphere, including the frequency and size of bolide impacts, have strongly implicated submarine hydrothermal vent systems as the likely habitat for the earliest organisms and ecosystems, while stimulating considerable discussion, hypotheses and experiments related to chemical and biochemical evolution. Some of the key questions regarding the origins of life at submarine hydrothermal vent environments are focussed on the effects of temperature on synthesis and stability of organic compounds and the characteristics of the earliest organisms on earth. There is strong molecular and physiological evidence from present-day mircoorganisms that the earliest organisms on earth were capable of growing at high temperatures (about 90 C) and under conditions found in volcanic environments. These 'Archaea', the living ancestors of all life forms, display a variety of strategies for growth and survival at high temperatures, including thermostable enzymes active at temperatures about 140 C. Further molecular and biochemical characterization of the presently cultured thermophiles, as well as future work with the many species, particularly from subsurface crustal environments, not yet isolated in culture, may help resolve some of the important questions regarding the nature of the first organisms that evolved on earth."

Levinton holds that biological innovation has continued unabated at the species level since the Cambrian explosion, but that new body plans; that is, new phyla; have not evolved for hundreds of millions of years.

These two giant planets can gravitationally deflect potentially devastating asteroids and comets away from the earth. It seems now that we are doubly lucky! Computer runs demonstrate that the presence of our large moon has stabilized the earth's spin axis down the eons. Presently, the earth's spin axis makes an angle of 23.5 with the plane of the earth's orbit (its "obliquity"). The well-known result is our yearly procession of seasons. Without the steadying effect of the moon, however, the earth's obliquity would probably have swung chaotically over much larger values. Such extreme changes would have been inimical to the development of life, particularly advanced life.

Science Frontiers ONLINE No. 50: Mar-Apr 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Feathered Flights Of Fancy Some more salvos have been fired in an endlessly fascinating controversy (at least it is that to us). 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. 13: Winter 1981 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Terrestrial Life Older Than Expected The oldest fossils found so far are dated at 3.5 billion years ago. Discovered in Australia, these life forms seem to have been capable of synthesizing their own food, much like present-day plants. In other words, these life forms were not so primitive after all. If we are to assume that still simpler life and pre-life chemical evolution preceded these fossils, the advent of life on earth must be pushed back much farther to allow time for gestation. (Anonymous; "Oldest Life-Forms May Have Made Own Food," Eos, 61:578, 1980.) Comment. Another possibility is that life did not originate on earth and was instead brought here on comets, meteorites, etc. From Science Frontiers #13, Winter 1981 . 1981-2000 William R. Corliss ...
