(Bottom) Aerodynamic diagram for a flying frog. Falling frogs have always been a Fortean favorite. These particular frogs plummet to earth in uncontrolled, unchecked free fall after (presumably) being lofted by whirlwinds. But there are frogs that are aerodynamically more sophisticated; these creatures glide and parachute through the dense tropical forests. S.B . Emerson and M.A .R Koehl have inquired into (even resorting to models in wind tunnels) the morphological and behavioral changes that have accompanied the repeated evolutions of these airworthy amphibians. "This paper reports an examination of the shift from aboreal to 'flying' frogs where we evaluate the the aerodynamic performance consequences of both a behavioral and morphological change. 'Flying' frogs have evolved independently several times among the 3,400 species of anurans. Although the particular nonflying sister species to each flying form remains unknown, in all cases flyers are distinguished from related, nonaerial, aboreal frogs by a similar suite of morphological characters: enlarged hands and feet, full webbing on the fingers and toes, and accessory skin flaps on the lateral margins of the arms and legs. 'Flying' frogs are not capable of powered flight, but do travel considerable horizontal distances during vertical descent. They are technically classified as gliders because they can descend at an angle less than 45 to the horizontal ...

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 Evolution Of Man And Malaria Malarial parasites are customarily classified according to the species infected and then further subdivided by morphology and biological characteristics. The two assumptions implicit in this classification procedure, which is supposed to mirror actual historical evolution, are: Malarial parasites evolved in parallel with their hosts; and Morphology is a measure of evolutionary relatedness. With modern biochemical techniques it is possible to test these assumptions by comparing the DNA structures of the different malarial parasites. P. falcipa rum, the parasite transmitting the most deadly human malaria, turns out to be more closely related to rodent and avian malaria than the other primate malarias. Therefore, assumption #1 above is in correct in this view. Assumption #2 is also wrong because some species of malaria parasites which are very similar morphologically are quite different DNAwise. (McCutchan, Thomas F., et al; "Evolutionary Relatedness of Plasmodium Species as Determined by the Structure of DNA," Science, 225:808, 1984.) Comment. The article does not draw attention to still another assumption; namely, that similarities are measures of evolutionary relatedness. If this as sumption isn't correct, evolutionary family trees based on bodily structure, which means most of the family trees in the textbooks, may not truly reflect what really happened in the development of life. Further, if malarial parasites did evolve along with their hosts, hu man evolution seems farther removed from the evolution ...

... Our title comes from L. Van Valen's review of a book by D.I . Williamson entitled Larvae and Evolution: Toward a New Biology . We can only touch upon a few of the many profound anomalies raised by the book. We begin with a paragraph from Van Valen's review: "Williamson has given us a new set of anomalies. Mostly he does this by showing that what we know doesn't fit together as well as we thought it did. In particular, the major phylogeny of the animal kingdom as estimated from adult characters doesn't fir very well with that estimated from larvae. Such a discrepancy for different stages has occasionally been reported within families of insects, and it has an apparent resemblance to the discordance occasionally found between phylogenies inferred from morphological and molecular characters. In such cases, the usual conclusion (I ignore data chauvinists) is that we should somehow use all the available information to infer the correct phylogeny. After all, there was just one real phylogeny that occurred in the past, and we want to find it as closely as we can." Comment inserted by the compiler. Van Valen is saying that three evolutionary Trees of Life can be drawn from adult morphology, DNA structure, and larval morphology, and that they may not look the same. Caterpillars may yield a family tree different from that inferred from the butterflies. Which is correct, or are they all correct? Back to the review. Waxing heretical, Williamson points out that an organism may have more than one phylogeny ! Larvae may have ancestries ...

The biological implications of the mollusc lineages drawn up by Willianson are rather profound. In the present item, Williamson complains that scientists and critics have focussed primarily upon his claim that his mollusc lineages support the punctuated evolution model (which they do) but avoid his main point: namely, that the lineages are static over very long periods of time. They do not change slowly, bit by morphological bit, into new species as an evolutionist would expect. Instead, they remain un-changed until they become extinct. This striking aspect of the fossil record is not predicted by neo-Darwinism -- and there is the rub! (Williamson, Peter G.; "Morphological Stasis and Developmental Constraint: Real Problems for Neo-Darwinism," Nature, 294:214, 1981.) Comment. In neo-Darwinism, evolution unfolds by small accumulated changes, the causes of which may be chemicals in the environment, nuclear radiation, and other "stresses." Neo-Darwinism goes hand-in-hand with geological Uniformitarianism, both of which are favored philosophically by scientists because slow change is more amenable to scientific explanation. The large sidewise steps of punctuated evolution are difficult to explain in terms of known "forces." In this context, the radical concepts of directed panspermia and the impact ...

Science Frontiers ONLINE No. 41: Sep-Oct 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The deceitful she-males "In many diverse taxa, males of the same species often exhibit multiple mating strategies. One well-documented alternative male reproductive pattern is 'female mimicry,' whereby males assume a female-like morphology or mimic female behavior patterns. In some species males mimic both female morphology and behavior. We report here female mimicry in a reptile, the red-sided garter snake (Thamnophis sirtalis parietalis). This form of mimicry is unique in that it is expressed as a physiological feminization. Courting male red-sided garter snakes detect a female-specific pheromone and normally avoid courting other males. However, a small proportion of males release a pheromone that attracts other males, as though they were females. In the field, mating aggregations of 5-17 males were observed formed around these individual attractive males, which we have termed 'she-males.' In competitive mating trials, she-males mated with females significantly more often than did normal males, demonstrating not only reproductive competence but also a possible selective advantage to males with this female-like pheromone." In the competitive mating trials, the she-males were successful in 29 out of 42 trials. The normal males won out in only 13! The authors ask the question: Why aren't all males she-males given such an advantage? (Mason, Robert T., and Crews, David; "Female ...

... further suspicions about the 1.5 % figure. (Gibbons, Ann; "Which of Our Genes Make Us Human?" Science, 281:1432, 1998.) Comments. It is easy to see how gross comparisons of DNA might miss important details. The popular "DNA-hybridization" method simply mixes together strands of DNA from the two species being compared. These are allowed to combine, and then they are heated to see how much temperature is required to force them apart. Chromosome numbers and bandings have little if any effect on these crude comparisons of the bare DNA strands that have been stripped from their genes and chromosomes. The significance of all this transcends the comparisons of humans and chimps. Modern taxonomy of all life forms depends increasingly upon DNA comparisons rather than upon morphology. If DNA comparisons can be as misleading as they are in humans and chimps, those textbook family trees that are supposed to tell us how life evolved may also be giving us an erroneous history of life. To underscore the problem, sometimes DNA genetic differences do not result in big morphological changes. For example, Three-toed Woodpeckers hammer on trees all over the northern reaches of North America and Eurasia. These birds all look alike and interbreed freely. Yet, some of the birds differ so much genetically that they should be classified as different species on that basis. (See BBG1 in Biological Anomalies: Birds.)

Williamson has scrutinized the distribution of some 190 faunas with high stratigraphic resolution; that is, he believes he has been able to sketch for the first evolutionary events on a fine time scale. Williamson underlines three important observations: (1 ) Species seemed to arise suddenly, as predicted by the "punctuated evolution" model; (2 ) The formation of new species was accompanied by marked developmental instability in the transitional forms; and (3 ) All lineages were morphologically stable for long periods -- they did not change form! The biological implications of this important study are summarized in the preceding item. (Williamson, P.G .; "Palaeontological Documentation in Cenozoic Molluscs from Turkana Basin," Nature, 293:437, 1981.) Comment.

According to Williamson's results, transitional forms would be few in number and display considerable morphological instability.

The wave crests are about 50 kilometers apart; lengthwise, they stretch up to 1.000 kilometers; altitude, about 85 kilometers. As many as ten waves may be seen at the same time. Morphologically, these waves resemble noctilucent clouds, which are sun-illumined, high-altitude clouds. The infrared waves, however, appear when the sun is well below the horizon. Since these waves are seen only at low angles over the horizon, some geophysicists propose they are the result of a geometric effect produced by viewing a rippled layer of weakly emitting gases in the upper atmosphere. When one looks at this rippled layer just above the horizon, one sees alternating thick and thin sections due to the perspective. The thick portions will appear brighter than the thin sections. As for the origin of this postulated rippled layer; no one is sure. Gravity waves may be involved. (Herse, M.; "Waves in the OH Emissive Layer," Science, 225:172, 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?

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.

Despite assurances to the contrary, we must ask if we really know the whole story. These doubts manifest themselves as we see that creatures that are very much alike genetically may be radically different morphologically. In this vein, C. Ventner asserts that all higher vertebrates have roughly the same genes. The animals that result from these re-markedly similar genomes depend upon when specific genes are turned on and off. Ventner says, "We have the same number of genes as cats and dogs, but differently regulated." The genes themselves are supposed to be simply protein factories. Somehow, they are turned on and off (" expressing" themselves) in just the right sequences to help build the target animal. In a far-stretched analogy, the genes are the instruments in an orchestra and the proteins they produce are the notes in a symphony. But where are the symphony's score and its conductor? Very similar orchestras, it seems, can play radically different symphonies given different scores as interpreted by a maestro.

After the layers were deposited, they were deeply eroded by some event in Martian history that seems related to the formation of the great outflow channels associated with Valles Marineris.

Such abrupt speciation is tough enough to explain, but even more daunting are those species untouched by change over millions, even hundreds of millions of years. Indeed, the major characteristic of the fossil record and, therefore, earth life as a whole, has been stasis rather than speciation, despite all manner of asteroid impacts and climatic traumas. Nevertheless, many biologists think that species are somehow frozen in time by environmental forces that keep them from straying from their little niches. This being so, paleontologist D.

This is not so! "Nonfertilizing sperm with special morphologies have long been known to exist in invertebrates. Until recently, abnormal sperm in mammals were considered errors in production. Now, however, Baker and Bellis have proposed that mammalian sperm, like some invertebrate sperm are polymorphic and adapted to a variety of nonfertilizing roles in sperm competition, including prevention of passage of sperm inseminated by another male. More specifically, their 'kamikaze' hypothesis proposes that deformed mammalian sperm are adapted to fa cilitate the formation and functioning of copulatory plugs."

Williams and Gilbert, for example, have found that a number of Passiflora species, which are heavily defoliated by the larvae of Heliconius butterflies, have developed tiny structures that closely resemble in size, shape, and color the eggs of these butterflies. Heliconius butterflies, when searching for likely plants on which to lay eggs, tend to avoid plants that already have eggs on them. The plants' fake eggs, then, help protect the plant from predation.

... until just a few thousand years ago, the solar system was cruising through interstellar space that was almost devoid of matter. Then, perhaps within historical times, 2,000-8 ,000 years ago, the solar system plunged into an interstellar gas cloud. This cloud is believed to be the remnant of the bubble of matter shot into space perhaps 250,000 years ago by a supernova in the Scorpius-Centaurus region. This tenuous cloud of gas feeds matter into the solar system, some of which interacts with the solar wind and, therefore, affects the geomagnetic field, too. Climate changes may have been caused by entry into this cloud, and very likely the flux of cosmic rays impinging on the earth would have been modulated.

The unique terrestrial life forms had to develop in less time than this. (Hickman, Carole S., and Lipps, Jere H.; "Geologic Youth of Galapagos Confirmed by Marine Stratigraphy and Paleontology," Science, 227:1578, 1985.) Comments. Several remarks seem appropriate here: (1 ) The varied fauna and flora of the Galapagos did not evolve independently; viz., the bills of the Darwin finches are tailored to specific food sources (plants). Many species changed rapidly and in concert. (2 ) A recent Science article (228: 1187, 1985) notes that inbred mice often evolve different morphological characteristics very quickly. This observation probably applies to the initial Galapagos populations, which must have been small and inbred. (3 ) Harking back to the item on the Guadeloupe skeleton, the Galapagos display similar strata of limestone, beach rock, etc. Until now, the limestones had been dated from the Miocene to the Pleistocene, but according to Hickman and Lipps they must be much younger than Miocene.

... Frontiers ONLINE No. 41: Sep-Oct 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Evolution's motor runs fast and quietly M. Kimura has been promulgating what he terms The Neutral Theory of Evolution. He concludes that "the most prev-alent evolutionary changes that have occurred at the molecular level, that is in the genetic material itself, since the origin of life on Earth are those that have been caused by random genetic drift rather than by positive Darwinian selection." Kimua maintains and can experimentally prove to some extent that the genetic material of all organisms changes rapidly and constantly. The genes change much more rapidly than scientists believed just a few years ago. We observe few if any changes at the phenotype level (organism morphology) because the overwhelming majority of these changes are neutral. They confer no significant advantage or disadvantage on the organism. In fact, Kimura and others have demonstrated that the fastest molecular evolution occurs in the least important genes. It is fastest of all in the pseudogenes or dead genes, which seem to have no discernable functions. In other words, the genetic engine is running, but the gears are in neutral! In Kimura's thinking, these molecular changes may eventually become important at the phenotype level if the environment changes or there is some other destabilizing influence. Kimura is the author of the 1983 book The Neutral Theory of Molecular Evolution. Although Kimura has some experimental support, his theory is not widely accepted.

... adjoined a massive algal reef. Here, many "experimental" forms of life prospered and succumbed. The Burgess Shale is probably the world's greatest depository of fossils of softbodied creatures. Quoting Stephen Jay Gould: "The Burgess (fortunately for us) occupies a crucial time in life's history. It represents our only 'window' upon the first great radiation of complex life on earth. All but one or two modern phyla originated in a burst of evolutionary activity associated with the so-called Cambrian explosion some 570 million years ago. The Burgess provides our only peek at the soft-bodied forms of this first flowering. All other soft-bodied fossil assemblages are much younger; they represent faunas well past the initial burst and sorting out of Cambrian times." The morphological diversity of the Burgess Shale, incorporating many bizarre forms of life, represents a true biological revolution. Here are found a dozen genera that do not fit into any modern phylum. Most of the novelties never survived into modern times.

... Sourcebook Subjects The fossil record and the quantization of life!A recent article on the possible quantization of galaxies was placed immediately before an interview with S. Stanley, one of the proponents of punctuated evolution. Either fate or the mysterious forces of seriality seemed to be saying that it is now time to broach the subject of the quantization of life itself. The reader can blame Stanley only for the stimulus and his discussions of speciation and the discontinuous (quantized?) fossil record. (Campbell, Neil A.; "Resetting the Evolutionary Timetable," BioScience, 36:722, 1986.) Comments. When we suggest quantization in biology, two phenomena come to the fore: 1. The obvious splitting of life into well-defined states -- the species -- as defined morphologically and/or by the genetic code; and 2. 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. In physics the analogous phenomena would be: (1 ) The chemical elements and their isotopes (or an atom's energy levels); and (2 ) The lack of transitional forms. Straining the analogy still further, the evolution of one species into another simply means that life-as-a -whole moves from one quantized state to another. There need be no ...

From among many possible comments, we settle for just one: It is relevant that mtDNA is not the nDNA (nuclear DNA) that is the primary determinant of an animal's morphology and other attributes. Scientific consensus now holds that mtDNA comes from bacteria that invaded complex cells (eukaryotes) and set up housekeeping in them eons ago. The mitochondria are called "endosymbionts," but we must wonder how symbiotic they really are. Not only does mtDNA mutate much faster than nDNA (" our" DNA), but the mitochondria the mtDNA serves must have different evolutionary goals from us; that is, mitochondria might really be parasites and we are their hosts!

... Initial bipedalism!Our anomaly-collecting net has pulled in an interesting catch; namely, CERBI (Centre 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.
