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.

Major Paradigms Targeted Anomalies exist only when they challenge paradigms and hypotheses. It is unavoidable, therefore, that some paradigms, widely considered to be fact, will be contradicted by many of the phenomena listed in this Outline. For example, the following paradigms that presently dominate scientific thinking are her considered to be at risk: The expanding universe The Big Bang origin of the universe Neo-Darwinism (specifically, evolution via random mutation and natural selection) That genomes are the complete blueprint for lifeforms Plate tectonics/continental drift Special and General Relativity View Cart Buy online via PayPal with MC/Visa/Amex 296 pages, softcover, $17.95, 244 illus., Jan 2003.

Furthermore, both mtDNA samples differ from that of modern humans by a substantial 7%. These two innocent-appearing, widely publicized numbers have far-reaching implications: Modern humans and Neanderthals are only very distantly related, and they certainly never interbred, as suggested in many recent, popular articles; and Since neither Neanderthal mtDNA sample is closer to that of modern Europeans than it is any other modern human population, the so-called "multiregional" theory of human evolution and dispersion is unlikely to be correct. Thus, the out-of-Africa theory is favored;. These data and their implications stimulate several observations and comments; only one of which is mentioned in the references given below. F.H . Smith, an anthropologist from Northern Illinois University and a supporter of the multiregional theory, opines that 30,000-40,000 years ago the mtDNA of the early humans, who were mixing it up with the Neanderthals, was certainly very different from what it is today.

... dialog of the deaf" between the Darwinists and the Creationists, we are perpetually exposed to their extreme, non-negotiable positions. The Darwinists insist upon their one-gene/one-protein genome in which random mutations slowly accumulate and adapt living things to the changing environment. The Creationists only accept a one-time, supernatural creation of "kinds" plus minor adaptations (" microevolution"). J.A . Shapiro, a professor at the University of Chicago, is searching for a "third way," a scientific, non-Darwinian way. Shapiro maintains that five decades of genetic and molecular-biology research have transformed our vision of life. Ile compares the conceptual changes to those accompanying the transition from classical physics to relativity and quantum mechanics. This new theory of evolution -- his "third" way -- will emerge from the convergence of biology and information science. Genomes, asserts Shapiro, are not really the static "beads on a string" envisioned by the Darwinians. Rather, they are fluid and complex. Genes are now seen as multipurpose elements that turn on and off as required for the survival and well-being of the organism they belong to. In this paradigm-eroding paper (referenced below), Shapiro describes four categories of molecular discoveries that have revised our thinking about how evolution works: (1 ) Genome Organization; (2 ) Cellular-Repair Capabilities; (3 ) Mobile Genetic Elements and Natural Genetic Engineering; and (4 ) Cellular Information Processing. He then writes: The point of this discussion is that ...

Science Frontiers ONLINE No. 137: SEP-OCT 2001 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Mysterious Losses And Acquisitions of Color Vision The eyes of most mammals incorporate two types of color-sensitive cones; one for seeing blue light, the other for green light. Such mammals have bichromatic vision and discern colors rather well. Humans and the other primates are blessed with trichromatic vision, for their eyes have cones that register red light. Does this indicate evolution superiority? Hardly, birds possess five types of color-sensitive cones that sense two additional parts of the spectrum. How and why these enhancements in color vision occurred are not well-understood. Nor do we know why they were restricted to mammals and birds; although it is easy to fabricate several survival-of-the-fittest scenarios. The "how" part of the mystery is particularly hard to grasp in neo-Darwinian terms because the complex pigments that confer spectral sensitivity upon the cones represent remarkable, complex chemical syntheses. 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). This deficiency is doubly perplexing: Sensitivity to blue light is highly desirable in the ocean environment because it is blue light that penetrates seawater well. The loss occurred in two mammalian lineages not particularly closely related on ...

Are the bits representing the multiplication table encoded in a line of proteins of different types or in their sequence or, perhaps, their three-dimensional configurations? Does anyone really know what our brain's hard drive looks like? Maybe memory is hologrammic. And when a memory is pulled off the mind's hard drive, how is the information conveyed to the central processing unit, assuming there is one? Is it all done through nervous impulses, or are proteins transferred bodily. This computer analogy is probably incorrect. Nature is probably cleverer than PC makers!

Photoreceptors are sensitive to light but do not produce images. They are found in many groups of animals. Even humans possess photoreceptors besides their eyes; specifically, in the pineal gland and, perhaps, the knees. (SF#116, SF#117) The pineal gland (our "third eye") may have registered photons at some stage in our evolution, but it is now useless or adapted to other purposes. The arthropods, however, still find photoreceptors useful. Crayfish have them on their abdomens, where they initiate an escape response when illuminated. Additionally, the blind shrimp that collect around the glowing deep-sea vents have photoreceptors perched on their backs, presumably to guide them to their prey located around the luminous vents. Recently, the Japanese yellow swallowtail butterflies were discovered to sport photoreceptors on their genitalia. These I are used during mating to confirm the position of the female's ovipositor.(Arikawa, Kentaro; "Hindsight of Butterflies," BioScience, 51:219, 2001.) Barn-Owl auditory neurons multiple signals. Barn Owls can locate rustling mice in the dark with high precision. They discern their prey by sound rather than light.

... fall into orderly classes. The clear implication is that protein folds and, by extension via further research, the protein molecules themselves, are also natural and reducible just like the salt crystals. If proteins are natural, perhaps even more complex biological forms are also, and so on up the complexity ladder to viruses (which often look like crystals through the microscope), bacteria, and even (gasp!) mammals. This is, of course, reductionism in the extreme. But the successes with protein folding have led two New Zealand biochemists to speculate as follows: If it does turn out that a substantial amount of higher biological form is natural, then the implications will be radical and far-reaching. It will mean that physical laws must have had a far greater role in the evolution of biological form than is generally assumed. And it will mean a return to the pre-Darwinian conception that underlying all the diversity of life is a finite set of natural forms that will recur over and over again anywhere in the cosmos where there is carbon-based life.

Many of the multitudinous studies looking into the season-of-birth correlations are very specialized and employ small samples. For example, English professional soccer players in the 1991-1992 season were twice as likely to have been born September through November. Mental traits are also influenced by season-ofbirth. More medical students are born April through June than can be explained by chance. Best of all (for us) is the following correlation: Perhaps the most unusual seasonal effect is found amongst scientists who support revolutionary theories. It seems that academics who were quick to support controversial theories such as relativity and evolution tended to he born between October and April.

An interesting sort of sperm ejection occurs among Dunnocks, small brown birds common in English gardens. Alpha males try to prevent matings by lower-ranking males but are rarely successful. Most Dunnock matings are preceded by a ritual-like phenomenon called "cloaca-pecking." The female raises her tail exposing the cloaca. Instead of mating, the anticipating male pecks at the cloaca, an action that stimulates a pumping action and ejection of a droplet of sperm from previous matings. After the male inspects the droplet, normal mating follows. This bizarre scenario required the coordinated evolution of two different kinds of behavior (male and female) as well as the development of the female's sperm-ejection mechanism.

Science Frontiers ONLINE No. 83: Sep-Oct 1992 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Flat-faced hominid skulls from china The "African Eve" theory of human evolution was given much play in the media a few years back. According to the "African" view, modern humans arose exclusively in Africa and, about 100,000 years ago, expanded rapidly from there into Europe and Asia, displacing "lesser" hominids. Unfortunately, the DNA studies that stimulated this conjecture have been found to be flawed. And now new fossil testimony casts further doubt. In 1989 and 1990, near the Han River, in China's Hube Province, anthropologists found hominid skulls with the characteristic flat faces of modern humans. These skulls seem to be about 350,000 years old. Although they apparently retain some primitive features, paleoanthropologist D. Erler, of the University of California, asserted, "This shows that modern features were emerging in different parts of the world." In other words, all of the evolutionary action was not confined to Africa. Proponents of the "African Eve" theory retort that the dating of the Chinese skulls is questionable and that flat faces alone are not enough to support the idea that modern humans arose separately in widely separated locales? (Gibbons, Ann; "An About-Face for Modern Human Origins," Science, 256: 1521, 1992. Also: Bower, Bruce; "Erectus Unhinged," Science News, 141:408, 1992.) Comment ...

The record of human evolution is littered with skeletons -- not only the legitimate bones of early hominids but also with discarded evolutionary charts and discredited taxons. A taxon is a welldefined biological classification, such as a phylum or species. We modern humans are given the label Homo sapiens. We are told with great assurance that we evolved from earlier hominids, such as Homo erectus and, perhaps, Homo nean derthalis. Homo erectus has long been a key feature of all those charts of human evolution decorating our textbooks. But this venerable taxon is getting fuzzier and fuzzier.

It had to be something that has not happened again down the long eons that followed, for never again has nature favored our planet in this way. Never again were any more of life's major body plans (the phyla) synthesized. Even ardent evolutionists marvel at the newly measured intensity of this moment. For example, S.J .

This is the same team that claimed the synthesis of the first self-replicating molecule in 1990. "Now the same chemists have carried out experiments with two more selfreplicating molecules, and discovered that they can cooperate, catalysing each other's formation. Furthermore, when one of the molecules is exposed to ultraviolet light and is 'mutated', it becomes 'aggressive' and takes over the system.

These rebounding universes are in a sense mutated universes, which have been slightly modified during the physical trauma of collapsing into singularities. Now comes a stimulating thought. The most abundant sort of universe occupying the metauniverse will be that type that generates the most new black holes during its expansion and contraction phases, for each of its "progeny" can spawn a new universe of its own. As in biological Darwinism, these are the "selected" universes. Some universes may fail to reproduce at all. Thus, with the help of small mutations occurring during each bounce, the metauniverse and its constituent universes are evolving like biological life -- but towards what?

Levinton, in a long article in the November 1992 Scientific American, explores the enigma of the Cambrian explosion. Did some unknown evolutionary stimuli prevail 570 million years ago that made the Cambrian different from all periods that followed? Or, has something damped evolutionary creativity since then? 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. Therefore, something special and very mysterious -- some highly creative "force" -- existed then but is with us no longer.

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.

"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."

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.

The Copernican Principle, in particular, leads to all sorts of profound prophecies. The Copernican Primciple states that the earth does not occupy a special place in the cosmos. To this we add Darwinism, which asserts that, in the realm of biology, human origin is not special either; i.e ., we enjoy no special place among life forms. Building upon these two general "beliefs," J.R . Gott, III, proceeds to estimate the longevities of various observables, such as the lifetime of a particular species. What follows is a long, highly technical computation of various probabilities, such as the evolution of intelligent life in the universe. All this (and there is a lot of it) leads to the following: "Making only the assumption that you are a random intelligent observer, limits for the total longevity of our species of 0.2 million to 8 million years can be derived at the 95% confidence level. Further consideration indicates that we are unlikely to colonize the Galaxy, and that we are likely to have a higher population than the median for intelligent species." Why won't we colonize the Galaxy? Not because we are not able to, Gott says, but because "living things do not usually live up to their maximum potential." Also of interest here is Gott's assessment of SETI (our Search for Extraterrestrial Intelligence). Will ...

Knowing that animals often communicated with one another employing chemicals called pheromones, Berliner suspected that the flasks had been releasing odorless human pheromones. Sure enough, analysis of the skin-derived materials proved him correct. Next: A Look Up the Nose. Biologists have long realized that animal noses actually contain two sensory channels. The first is the familiar olfactory system, which humans also possess. The second channel is the vomeronasal system. In animals, each system has its own separate organs, nerves, and bumps in the brain. The function of the vomeronasal system is pheromone detection. It was widely believed that humans had long ago discarded this sensory system along evolution's trail. But a closer look at the human nose by B. Jafek and D. Moran, affiliated with the Rocky Mountain Taste and Smell Center at the University of Colorado, revealed that all humans examined displayed two tiny pits on both sides of the septum, just inside the the opening of the nose. Behind the holes were tubes lined with unique cells that could well be pheromone detectors, since they responded positively to puffs of air laden with pheromones. In conclusion, we humans actually do have a sixth sense, and we are all enveloped in an aura -- not the luminous aura of the mystics but a cloud of pheromones. Somehow, our attitudes towards others are likely affected by these pheromones. (Blakeslee, Sandra; "Human Nose May Hold an Additional ...

To accomplish this, the fish must be able to detect time disparities between the two sets of signals less than 1 microsecond long. Their individual electroreceptors are not capable of handling such small time differences. Kawasaki has concluded that the jamming avoidance response can come only from highly sophisticated signal processing in the fish's central nervous system.

To understand the answer to the electric fish puzzle, we must restrict the discussion to those fish with active electric sensing systems. This group includes electric eels, South American knife fish, and African elephant snout fish. All of these have evolved, in a remarkable instance of parallel evolution, the capability of generating pulses of electricity. These pulses (up to 1,000 per second) radiate through the surrounding water. Prey and other nearby objects distort these oscillating electric fields. Electroreceptors on the fish and a sophisticated data processing system convert the field distortions into an "image" of the surroundings. M. and S.J . Lannoo, of Ball State University, have watched the black ghost knife fish, which plies murky Amazon waters, approach likely prey tail first. Swimming backward using an elongated belly fin, the knife fish slowly cruises past its potential victim. If the electrical image looks appetizing, the knife fish grabs its dinner with a forward lunge as it appears in front of it.

Females of these species usually survive to breed a second and even third year. The poor males, however, succumb due to "elevated levels of free corticosteroids in the blood and associated disease such as hemorrhagic ulceration of the gastric mucosa, anemia, and parasite infestation." In short, they seem programmed to die after mating, like the male octopus. And one wonders why evolution has wrought this mass die-off. In their studies of marsupial mice, C.R . Dickman and R.W . Braithwaite have extended the phenomenon to two new genera: Dasyurus and Parantechinus . They have also found that the phenomenon is a bit more complex. First, in P . apicalis, the male die-off occurs in some populations and not others. In D. hallucatus , the die-off may occur in the same population in some years and not others. Furthermore, the females of this species may on occasion all die off, too -- but after giving birth, of course.

The question asked in the article is whether science has missed something in its description of the origin and development of life. Just what makes molecules coalesce into cells and humans? The answer given is: spontaneous self-organization ! In other words, there is no guiding external force. Molecules do this spontaneously.

In 1988. Harvard molecular biologist John Cairns committed an act of scientific heresy. He proposed in a Nature article that bacteria living in an unfavorable environment are able to choose which mutations to produce to adapt to the stressful situation. Cairns made his directed-mutation hypothesis in response to an unusual finding -- data that strongly hinted bacterial mutations might occur more often when beneficial." The above quotation is the lead paragraph in a long BioScience article that details the consternation Cairns' results have created in the biological community. The problem that biology-as-a -discipline has is that it has deified a paradigm: neo-Darwinism. Now, neo-Darwinism is supported by many experiments showing that some mutations are indeed random. Consequently, as M. Gillis re-marks in her BioScience article, the biological community 'got locked into its belief that an organism cannot control its own mutation.' Furthermore, Cairns' claims recall the long battle with Lamarckism, a subject that biology has closed-the-book-on. In a nutshell, Lamarckism has been interred since the 1950s, and 'Nobody wants to give the appearance of straying from the neoDarwinism fold.' Gillis goes on to review some recent experiments supporting those of Cairns. But, impressive though these may be, there have been neo-Darwinian explanations for some of the results.

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.

The author of the present paper, A. H.

Castelez (Allegheny Observatory) has added to the mystery by pointing out that many socket stars show excess infrared emission. He considers this strong evidence that socket stars are surrounded by shells of dust and may represent an unrecognized stage of stellar evolution.

... d'Etudes et de Recherches sur la Bipedie Intiale). This Center, operated by F. de Sarre, publishes a little journal called Bipedia . In the first issue of Bipedia , de Sarre sets out, in English, his basic thesis: Abstract. "The explanation of Man's special nature is to be sought in the original combination formed by a primordial brain, the globular form of the skull and initial bipedalism. The ape, when compared with Man, appears to be rather a vestige of Man's ancestral line than his predecessor, according to the views of Max Westenhofer, Serge Frechkop, Klaas de Snoo and Bernard Heuvelmans. The study of the human morphology allows logically to carry the problem of Man's origin back to a very early stage of the evolution, and not to which has been reached by apes. From chromosomal and DNA comparison in the cells of living apes and people, several researches argue to-day that humans are genetically more like the common ancestor than is either Chimpanzees or other apes. The array of facts and considerations should be sufficient for an unbiased mind to discount away any idea of simian antecedents in Man's ascent." The body of the article supports de Sarre's thesis with observations from embryogenesis, comparative anatomy (skull, hand, foot), and phylogenesis. (de Sarre, Francois; "Initial Bipedalism: An Inquiry into Zoological Evidence," Bipedia , 1:3 , September 1988.) Comment. Obviously, de Sarre is taking an extreme position, and any observations supporting his ...

... boundary is anything but simple chemically and paleontologically. To illustrate, J.L . Bada and M. Zhao have found unusual amino acids in sediments laid down before and after this geological time marker. "They find that Danish sediments spanning the narrow boundary layer contain two amino acids, alpha-aminoisobutyric acid and isovaline, that are relatively uncommon in biological materials but abundant in the organicrich meteorites. They suggest that the body which collided with Earth 65 million years ago and left the telltale iridium residue may have been organic-rich, perhaps like a C-type asteroid or a comet. Such a possibility has interesting implications for the extinction and related atmospheric effects, and supports the idea that impact events could have supplied the Earth during a much earlier period with the raw materials for organic chemical evolution." Actually, the above quotation is pretty much in line with present mainstream thinking. Perhaps so, but Bada and Zhao identified two troubling anomalies. First, the amounts of amino acids found were surprisingly high. How could these complex molecules survive the searing temperatures engendered by high-velocity impact? Second, the amino acids may be abundant tens of centimeters above and below the K-T boundary clay containing the iridium, but they are virtually absent in the clay itself! (Cronin, John R.; "Amino Acids and Bolide Impacts," Nature, 339:423, 1989, Also: Monastersky, R.; "Rare Amino Acids Support Impact Theory," Science News, 135:356, 1989.) Reference.

... 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.) Comment. What an intriguing concept! Perhaps human male baldness also confers more cooling efficiency and is setting the stage for a new expansion of the human brain -- at least the male brain, sorry girls! More seriously, did the better blood cooling system develop in response to an enlarging brain, or vice versa? Even more seriously, it is simplistic to say that an organism just went ahead and evolved this way or that way. A bigger brain requires not only more cooling but a bigger skull, ...

... and the treated plants grew up stunted. But, it was serendipitously discovered, the same genes could also be triggered by spraying with water, by gusts of wind, and even by the human touch. Evident-ly, some of the genes in these plants can be turned on by various environmental stimuli, and thus affect future plant development. This mechanism per-haps explains why trees along the seacoast and timberline are stunted. (Crawford, Mark H., ed.; "Nolo Me Tangere," Science, 247:1036, 1990.) Comment. One is tempted to ask how widespread this phenomenon is in biology. Are humans, for example, born with a console of gene-buttons that the environment can push - as in cancer?

In their study O'Connor and Hermelin showed that the verbal memory factor in mnemonists was independent of IQ; also, data of special interest to the subjects were stored in their memories in categorized form. (O 'Connor, N., and Hermelin, B.; "The Memory Structure of Idiot-Savant Mnemonists," British Journal of Psychology, 80:97, 1989.) Comment. Psychological studies like the one reported above often do not emphasize the fantastic mental capabilities of idiot-savants.

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 ...

McLeod, a paleontologist at the Los Angeles County Museum of Natural History, has been studying the bones of a 10-million-year-old whale found in a backyard in Southern California. It is claimed that these bones "will fill an im portant gap in (the) knowledge of the evolution of whales." Actually, the opposite seems to be the case. "One of the interesting things about the discovery is that it appears 'this guy didn't follow the same evolutionary path as living whales,' McLeod says. Sperm whales today have well-developed teeth only in the lower jaw, whereas the fossil whale shows evidence of very large, very welldeveloped teeth in both upper and lower jaws." (Tyndall, Katie; "A Whale's Legacy," Insight, 49, June 15, 1987. Cr. C. Stiles.) Comment. One would think that a full mouth of teeth would serve sperm whales better, especially in their battles with the giant squid they prey upon. Is evolution reversing for whales?
