Because chromosomes are composed of genes and their DNA -- the information carriers of inheritance -- it reasonable to suppose that they are the "dance-masters." This expectation is enhanced if one holds that the genes are "selfish;" that is, they have their own evolutionary agendas, and all life forms exist only to execute their "will." But cell division would not occur at all without the action of the cell's bipolar spindle. This spindle is composed of microtubules -- rods of the protein "tubulin." Somehow , when cells are about to divide, they synthesize these microtubules, which then seem to organize themselves into orderly arrays (the bipolar spindles). Then, the microtubules sort out and separate the two sets of chromosomes required for the two new cells. So, far, our description conforms to what biologists have known and accepted for decades; but there is something more mysterious going on. In 1996, researchers discovered that they can actually substitute DNAcovered beads for the chromosomes, and the microtubules will still go through the motions of sorting and separating the chromosome-less strands. Actually, the microtubules will perform their act even without the DNA-covered beads. In a sense, the bipolar spindle is a puppetmaster, and the ...

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 ...

In southern Japan, roughly 4% of the populace are afflicted with this virus, so are some isolated groups living today in Columbia and Chile. Does this correlation prove that South America received settlers from Japan in the distant past? Such a biological linkage would augment pottery evidence from Peru and, especially, Ecuador where Jomon-style pottery 4,000-5 ,000 years old has been found on the coast. However, the HTLV-1 virus also could have been introduced to South America by more recent visitors. Is there any way to fix the timing of HTLV-1 's introduction to South America? Actually, there is. The DNA in viruses is not as durable as pottery shards, but it does hang around for a while, as seen is recent efforts to ex-tract DNA from from frozen mammoths for possible "revival" of the species. A team of Japanese and Chilean scientists has been searching for DNA surviving in 104 mummies deposited in South America's arid Atacama Desert 1,200-1 ,500 years ago. Two of the mummies still retained DNA; and one of them included shards of DNA from HTLV-1 . This certainly doesn't prove trans-Pacific diffusion, but it helps. (Holden, Constance; "Backtracking ...

The curious glows recently remarked at these vents (SF#87) have stimulated much speculation as to the potential role of these glows in the origin of life: "The history of hydrothermal activity predates the origin of life, and light in the deep sea has been a continuous phenomenon on a geological time scale and may have served either as a seed or refugium for the evolution of biological photochemical reactions or adaptations." We formally classify this item under GEOPHYSICS because scientists are still pondering how these glows are created. Some of the light is obviously black-body radiation from the very hot (350 C) water but: ". .. other potential, narrow-band sources of light may be superimposed on the blackbody radiation spectrum, including crystaloluminescence, Cerenkov radiation, chemiluminescence, triboluminescence, sonoluminescence, and the burning of methane in supercritical water." (Van Dover, Cindy Lee, et al; "Light at Deep Sea Hydrothermal Vents," Eos, vol. 75, 1994.) Comment. If cold, diffuse molecular clouds in deep space can synthesize glycine, imagine what the hot, chemically-rich fluids around hydrothermal vents might be able to do. ...

First, there was the admission that a few small craters, like Meteor Crater in Arizona, just might be of meteoric origin; then, more and bigger craters (astroblemes) were recognized; and, recently, the discovery of the iridium-rich layer at the Cretaceious-Tertiary boundary has made the subject very popular, as evidenced by the following three items: A long, very thorough and scientific review of geological and biological changes caused by meteor strikes throughout the earth's history.

Hybrids bisect these initial paths and would end up in the Alps. Many young birds migrate successfully without help from older birds who have made the trip before. The implication is that migration instructions, perhaps even some sort of map of astronomical or geo graphical references, are somehow written upon the genes inherited from their parents. Just how maps can be coded into gene structure is anyone's guess. (In fact, since the DNA in the genes seems to cody only for protein synthesis, the locations and characters of inheritable maps and other biological instructions are not immediately obvious.) The problem has been exacerbated by recent experiments with German and Austrian blackcaps. These two common European warbler species take different routes to Africa in the winter. The Ger-man blackcaps fly southwest and the Austrian southeast--routes 50 apart. A. Helbig has crossed the German and Austrian blackcaps to see what route(s ) their hybrid offspring would take. Curiously, they favored a route intermediate between those of their parents. The hybrids' route -- bisecting those of the parents' -- would take the hybrids right into the Alps, where survival would be unlikely.

It was declared, rather imperiously, that a large asteroid had impacted the earth, causing much physical and biological devastation.

I.C . Eperon and his coworkers at the MRC Laboratory of Molecular Biology, England, have shown that "human mitochondria did not originate from recognizable relatives of present day organisms." The authors go even further, describing human mitochondria as a "radical departure." (Eperon, I.C ., et al; "Distinctive Sequence of Human Mitochondrial Ribosomal RNA Genes," Nature, 286:460, 1980.) Comment. The inferences above may be far-reaching. Mitochondria are vital components in the cells of the so-called higher organisms. Apparently possessing their own genetic material, they are suspected of being descendants of an cient bacteria that invaded and took up residence in cells. If human mitochondria are radically different, could changes in mitochondria be the source of the purported wide gap between humans and other animals?

An individual possessing perfect pitch can identify any musical note without comparing it to a reference note. It is said to be a uniquely human talent. (But how can we know?) Language, too, is thought to be be a gift accorded only to humans. Is there a biological connection between these "unique" capabilities? Since language is primarily a left-brain function, it is logical to see if the secret of perfect pitch resides in that half of the brain, too. This is just what a group of researchers headed by G. Schlaug did with the help of magnetic resonance imaging. They compared the planum temporale regions in the brains of 30 musicians (11 with perfect pitch, 19 without) and 30 non-musicians -- all matched for sex and age. The left planum temporale region was larger than the right for both musicians and non-musicians, but in the musicians the asymmetry was twice as great. Furthermore, the musicians blessed with perfect pitch were the most asymmetric of all in this respect.

Plants mimic insects, stones, other plants, and substrates (backgrounds). Repeatedly, Barrett asserts that all of these remarkable developments are the consequence of small, randome mutations guided by the forces of natural selection. To Barrett, plant mimicry is proof positive that evolution is true.

In this, they are morphic, like the cattle guards under Biology; and Sheldrake's hypothesis of morphic resonance should also apply. Two French researchers, F.J . Varela and J.C . Letelier, have applied a microcomputer in testing Sheldrake's theory. Briefly, they cleared the computer's memory and had it "grow a crystal" in the form of a unique, or at least very rare electronic state in the computer memory. Once this has been done, the time taken for the same pattern to be grown in subsequent attempts should become less and less. One of Sheldrake's major claims is that once a new crystal is synthesized it thereafter becomes easier and easier to resynthesize it -- due to the presence of morphogenic fields. But Varela and Letelier found that, even after 100 million crystallizations, no acceleration of the growing process was detectable. The authors conclude that either Sheldrake's hypothesis is falsified or that it does not apply to silicon chips.

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 " ...

This is mainstream biochemistry, although there is much here yet to be learned. A signalling medium that still survives well off the mainstream is the old idea that information is carried from cell to cell via electromagnetic radiation. Yes, we mean mitogenetic radiation--the infamous M-rays of the 1920s and 1930s. During this period about a thousand technical papers were published on mitogenetic radiation -- mostly in Russian. The champion of mitogenetic radiation was A.G . Gurwitsch. He claimed that fundamental biological functions, such as cell division, were communicated via ultraviolet light. Although a few other researchers said they detected mitogenetic radiation, most could not replicate Gurwitsch's work. Mitogenetic radiation was thereafter subjected to the "cold-fusion" treatment; it was one of those things that "wasn't so"! In a recent article in the Journal of Scientific Exploration, R.

This Issue Sourcebook Project Sourcebook Subjects More Disorder Here Produces Order There Physicists use the word "entropy" to describe the well-observed tendency of the universe to run down; that is, become more disorderly. In some situations, though, the increase in disorder (entropy) in one part of the universe can create order elsewhere. For example, if you add tiny plastic spheres of two sizes to salty water, you will not get a uniform mixture. Instead the larger spheres will pack together into tightly ordered crystaline shapes (representing more order) while the smaller spheres become more disordered. It is like watching cream unstir itself from coffee. It smacks of magic, but it is all within the laws of thermodynamics. This strange "force" exerted by entropy may explain some puzzling biological phenomena, such as the expulsion of nuclei from mammalian red blood cells before they enter the bloodstream as sacks of hemoglobin. The idea being that the increasing entropy of the proliferating hemoglobin molecules (analogous to the smaller spheres) is maximized when the nuclei (large spheres) are squeezed out of the cells altogether. (Kestenbaum, David; "Gentle Force of Entropy Bridges Disciplines," Science, 279:1849, 1998.) Comments. The red-blood-cell example presented in the article is on shaky ground, because while mammalian red blood cells do lack nuclei those of birds and reptiles retain theirs. (See BMC6 in Mammals II .)

"In the discussion in your columns about the application of quantitative methodology based on the study of evolutionary processes to the analysis of the development of human culture, there is an unquestioned assumption on both sides of that issue that quantitative theory, as expounded by practitioners such as Fisher, Haldane, Wright, Cavalli-Sforza and Maynard Smith, has been successful in illuminating and explaining the process of biological evolution and the genetic relationships between species. As far as I know, there is no evidence to support this assumption. Indeed, there is a vast number of observations unaccounted for in the extant quantitative evolutionary theories. Many of these observations (inducible mutation systems, rapid genomic changes involving mobile genetic elements, programmed changes in chromosome structure) challenge the most fundamental assumptions which these evolutionary theories make about the mechanisms of hereditary variation and the fixation of genetic differences."

In other words, DNA and genes are selfish, and ultimate parasites, directing the evolution of life only to maximize the production of DNA. This theme is not the subject of this paper by Doolittle and Sapienza. Rather, they wonder about those nonsense DNA sequences that do not code for protein. The presence of these "useless" bits of genetic material is often explained in terms of gene "expression." Emphasis is always on maximizing the "fitness" of the organism (phenotype). Perhaps this seemingly excess genetic material actually maximizes the fitness (survivability) of the DNA itself. Evolution thus occurs at DNA and gene (genome) levels, despite what transpires at the organism (phenotype) level. (Doolittle, W.

We know that mitochondria and chloroplasts have their own genetic material; evolution may be occurring at this level, too, independent of pressures for change on the organisms.

"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.

But in the Guaymas Basin, in the Gulf of California, the oil seeping out of the sediments is only 4240 years old! Actually, it could be even 500-3000 years younger than that for two reasons: (1 ) The organic debris that was C-14-dated may have taken many years to become incorporated in the sediments; and (2 ) The dating may be skewed by older material in the sediments. By subtraction, the oil might be as young as 1240 years! The picture geologists draw of the Guaymas Basin is that of a spreading center covered by perhaps a half kilometer of sediments.
