... question that the physical world is coherent and harmonious. Yet according to the traditional scientific picture, the Universe is just a random collection of particles with blind forces acting upon them. There is, then a deep mystery as to how a seemingly directionless assembly of passive entities conspire to produce the elaborate structure and complex organisation found in nature." The author of this introductory paragraph, P. Davies, asks, as we all do, "What is the origin of this creative power?" In groping for an answer, he presents first a common example of "blind" organization: the hexagonal convection cells in a pan of heated water. Using for a stepping stone the cooperative action of atoms in a laser, he leaps to the development of an embryo from a single strand of DNA! All such systems are "open"; that is, energy can flow in and out. They are also nonlinear, which means that chaotic, unpredictable action may occur. Davies implies that such action can be "creative," almost as if they possessed free will! His final example is that of the network with large numbers of interacting sites or nodes. With random inputs, large networks do exhibit self-organization. Network theory is now very popular in the field of artificial intelligence. (Remember the computer Hal in 2001?) Davies's conclusion: ". .. Neo-Darwinism, combined with the mathematical principles emerging from network theory and related topics, will, I am convinced, explain the 'miracle' of life satisfactorily." (Davies, ...

... Advancement of Science (AAAS) in Philadelphia, anthropological heresies ran rampant. T. Dillehay, who directed the Monte Verde work, declared that there were 15-20 other South American sites older than 11,500 years. Monte Verde itself may have been founded 33,000 years ago. D. Stanford, Smithsonian curator of archeology, opined that there were probably several waves of prehistoric immigration into the Americas across the Arctic, the Pacific Ocean (! ), and possibly even the Atlantic (! !) . [This is heresy no longer.] Supporting early Atlantic crossings are several dozen artifacts found in the eastern U.S . that closely resemble some found in France and Iberia. Stanford said, "We don't know yet what that means." Studies of DNA diversity among New World Indian populations find such large differences that at least 30,000 years would have been needed for these differences to develop. (Assuming, of course, a relatively homogeneous group of initial colonists.) Linguist, J. Nichols, from Berkeley, sees a similar diversity in the languages of New World peoples. Some 140 language families -- half the world total -- are found in the Americas. Nichols estimates that it would have taken a minimum of 40,000 years for such diversification. (Again assuming initial homogeneity.) Nichols also pointed out strong similarities in languages all around the Pacific Rim, from New Guinea north to Siberia, around Alaska, and down the west coast of the Americas.

... just one simple memory, the brain will quickly use up all available cells. It must be that individual brain cells can participate in the storage of many different memories. The conventional mem-ory-trace theory would have to be replaced by a new type of memory architecture. (Bower, Bruce; "Million-Cell Memories," Science News, 130:313, 1986) Comment. Our thinking about biological memory may be controlled by our preoccupation with the two-dimensional circuits of computer memories. Biological memories might be three-dimensional, or of even higher order. Some scientists have ventured that memory might entail electrical charge distribution patterns in the brain; such need not be limited to two dimensions. The same thinking can be applied to the storage of genetic information. While DNA, RNA, etc., may be pieces in the puzzle, the complete solution may include the ways in which these molecules are bent, twisted, convoluted, arrayed, juxtaposed, and so on. In a letter relating to the above article, P.J . Rosch points out that John's results are consistent with the holographic theory of brain function supported by Pribram and Bohm. "In a hologram, every element of the subject is distributed throughout the photographic plate, making it possible to reconstruct the entire original image from any portion of the picture. In this paradigm, the brain stores memory and deals with interactions by interpreting and integrating frequencies, retaining the data not in a localized area but dispersed throughout its substance."

Investigators have discovered cells carrying male DNA among a mother's blood cells 27 years after the birth a male child. Evidently, descendents of fetal cells escape during pregnancy and persist in the mother for years after birth. The mother thus becomes a blend of herself and her child (or, possibly, children) - a kind of chimera. The question is: Why doesn't the mother's immune system destroy these foreign cells? Some scientists speculate that these escaped and still-surviving cells may help explain why women are more susceptible than men to autoimmune diseases.

Then, fertilization occurred, but it was only partial. The sperm got to just one of the two or more cells derived from the egg.

No one knows how a parasite floating in the body cavity of its host can control the host's behavior.

Biologists have recently discovered that genes grasshopper about, constantly modifying genetic instructions -- at least that's the current thinking. Additional modification of genetic instructions seems to be accomplished by entities called "nomads" or "mobile dispersed genetic elements." One type of nomad is a simple ring of DNA called a plasmid. Plasmids seem to be identical to a kind of virus called a retrovirus, which can penetrate into cells and tamper with gene expression; that is, the way genetic instructions are interpreted. Plasmids have been discovered in maize, fruit flies, bacteria, and, now, humans -- and healthy people at that. No one is quite sure what these plasmids do. Even though they look like retroviruses, they may not be associated with illness, but rather help organisms adapt to changing environments. But no one really knows.

So, the human body is not only beset by new genetic instructions and the static introduced by invading viruses and other disease agents, but it has an indigenous population of nomads continually fiddling with our cells' genetic instructions.

(Bergh, Oivind, et al; "High Abundance of Viruses Found in Aquatic Environments," Nature, 340:467, 1989.) A sip of water could therefore introduce a billion virus particles into your stomach! This level of virus density in natural water is about 10 million times that formerly estimated. Besides reducing your thirst, what are the implications of this discovery? First, it suggests that bacteria in natural waters are probably kept in check by viruses as well as protozoans. So far, this sounds good. Second, since viruses can ferry genetic material between organisms via transduction (i .e ., host DNA is carried to the next host). This means that genes for antibody resistance and increased bacterial virulence (as present in sewage) may be spread quickly and widely. Also, "engineered bacteria" proposed for use in agriculture, viz., the ice-minus bacterium created to protect strawberries, may die, but their new genes will soon be everywhere.

"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.

With the help of this gene, an endless stream of prions emerges, and the animal is sick. In hamsters, which are employed in laboratory research on scrapie, a gene demarcated PrP has been implicated in scrapie. PrP is present in both healthy and infected hamster brains, but no one knows what its normal function is, if indeed it has one. (Anonymous; "Prion Gene," Scientific American, 253:60, July 1985.) Comment. One can make an immediate connection between the traitorous PrP genes in the hamster brains and the excess genetic material in humans and all life forms. Biologists commonly call excess genetic material "nonsense DNA" which only means that they haven't devined its purpose.

If the brain can fight disease and even control cell growth, why not a role for the mind in stimulating the development of new spe cies, perhaps in response to extreme environmental pressures, and perhaps not on the conscious level?
