I've been wondering if an informational field (some called it morphic
field) is behind the blueprint of biological growth and repair or if purely biochemical mechanism is enough to explain ALL biological process. By informational (morphic) field is meant an additional extended functionings of the atoms that doesn't rely on quantum coherence, etc. and effects (see related message "Are Particles Mini-Black Holes and Terminals of Informational Fields"). Dr. Robert Becker, a pioneer in regeneration and its relationship to Life" and asked whether some kind of morphogenetic field in-forms the biological process. If anyone knows or can point researches that describe in detail or show mathematical model of how biological and biochemical process alone can produce a human being from a single fertilized cell with all the intermediate steps of differentiation into the different tissues, organs, bones and their right placement and growth. Let me know and I'll throw away the belief of the possibility of informational fields in living things. In the following is a short excerpt of how Dr. Becker got puzzled about how their placement occurs without morphogenetic field. Since the book was written in 1985, Many updates have likely occured. So if you know of any, let me know and I'd give up the belief in the possibility and necessity of informational field in organizing the physical expression of living things and instead focus on its main role as consciousness interface in biological system and emotional regulators that act on the secondary medium of the brain. (I know I should post this in the sci.bio newgroups but just posting it here in case some may know the answer. Besides, physicists or biophysicists understand morphic field better than biologists) Quoting Dr. Becker: "The salaniander, directly descended from the evolutionary prototype of all land vertebrates, is a marvelously complex animal, almost as complicated as a human. Its forelimb is basically the same as ours. Yet all its interrelated parts grow back in the proper order-the same interlocking bones and muscles, all the delicate wrist bones, the coordinated fingers - and they're wired together with the proper nerve and blood vessel connections. The sarne day the limb is cut off, debris from dead cells is carried away in the bloodstream. Then some of the intact tissue begins to die back a short distance from the wound. During the first two or three days, cells of the epidermis-the outer layer of skin-begin to proliferate and migrate inwardly covering the wound surface. The epidermis then thickens over the apex of the stump into a transparent tissue called the apical cap. This stage is finished in about a week. By then, the blastema, the little ball of undifferentiated cells described by Morgan, has started to appear beneath the apical cap. This is the "organ" of regeneration, forming on the wound like a miniature embryo and very similar to the embryonic limb bud that gave rise to the leg in the first place. Its cells are totipotent, able to develop into all the different kinds of cells needed to reconstitute the limb. The blastema is ready in about two weeks. Even as it's forming, the cells at its outer edge start dividing rapidly, changing the blastema's shape to a cone and providing a steady source of raw material-new cells-for growth* After about three weeks, the blastema cells at the inner edge begin to differentiate into specialized types and arrange themselves into tissues, beginning with a cartilage collar around the old bone shaft. other tissues then form, and the new limb-beginning with a characteristic paddle shape that will become the hand-appears as though our of a mist. The elbow and long parts of the limb coalesce behind the hand, and the regrowth is complete (except for some slight enlargement) then the four digits reappear after about eight weeks. This process, exquisitely beautiful and seemingly simple, is full of problems for biology. What organizes the growth? What is the control factor? How does the blastema "know" that it must make a foreleg instead of a bind leg? (The salamander never makes a mistake.) How does all the information about the missing parts get to these undifferentiated cells, telling them what to become, which genes to activate, what protelns to make, where to position themselves? It's as if a pile of bricks were to spontaneousl y rearrange itself into a building, becoming not only walls but windows, light sockets, steel beams, and furniture in the process. Answers were sought by transplanting the blastema to other positions on the animal. The experiments only made matters worse. If the blastema was moved within five to seven days after it first appeared, and grafted near the hind leg, it grew into a second hind leg, even though it came from an amputated foreleg. Well, that was okay. The body could be divided into "spheres of influence- or "organizational territories," each of which contained information on the local anatomy. A blastema put into a hind-limb territory naturally became a hind limb. This was an attractive theory, but unfounded. Exactly what did this territory consist of? No one knew. To make matters worse, it was then found that transplantation of a slightly older blastema from a foreleg stump to a hind-limb area produced a foreleg. The young blastema knew where it was; the older one knew where it had been! Somehow this pinhead of primitive cells with absolutely no distinguishing characteristics contained enough information t o build a complete foreleg, no matter where it was placed. How? We still don't know. One attempt at an answer was the idea of a morphogenetic field, advanced by Paul Weiss in the 1930s and developed by H. V. Bronsted in the 1950s. Morphogenesis means "origin of form," and the field idea was simply an attempt to get closer to the control factor by reformulating the problem." --------- end quote (Note: a similar "morphogenetic field" thesis has been put up by Sheldrake see http://www.psych.uni-goettingen.de/h...hicfields.html |

'Morphic resonance is a term coined by Rupert Sheldrake for what he thinks
is "the basis of memory in nature....the idea of mysterious telepathy-type interconnections between organisms and of collective memories within species."' http://skepdic.com/morphicres.html IOW, it's all a load of crap. With all the vocabulary abuse going on, nobody has produced a measurable "morphic field" in the laboratory, or demonstrated the interaction of such a field with any observable object. To paraphrase Tom Lehrer, parapsychology "is like a sewer, what you get out of it depends on what you put into it." Tom Davidson Richmond, VA |

Different groups use different terms. So let us not be limited by
Sheldrake stuff, etc. If someone hates Sheldrake, it doesn't mean his stuff represents the rest. Just like if someone hates Watson, it doesn't mean his DNA Model is incorrect. We must study it for what it is, without terms or siding with groups. In China and elsewhere, there are many experiments on Qi.. or an energetic aspect of this non_local informational field. The following is one such experiment. There are other experiments elsewhere. We must create such experiments too to settle the matter (but many physicists don't bother to start any because they don't even believe it makes any sense... so how can they disprove it when they won't do the experiments in the first place). http://www.accessv.com/~yuan/yansci/...Qigong_JSE.pdf |

It's not our job to educate you. If you want evidence on the
non-existence of your silly little theory get off your ass and look for it - there is a tonne so it won't be hard. Here's a tip - google for "developmental biology". You may also want to ask biologists, not physicist, about stuff like this - but you & I both know what would happen if you posted this crap on sci.bio, or any other bio newsgroup. A few minor points: 1) There is no electricity within most organisms (electric eels aside). This is a popular misconception. Instead of having electricity (as defined as moving flows of electrons), living organisms have electro-chemical gradients. What this translates to is our bodies have the capability of concentrating ions in specific compartments within the cell. For example, hydrogen ions are concentrated within mitochondria where they are used to power a "pump" which generates ATP, our bodies power supply. Free electrons simply are not present in our bodies - they are always contained within a molecular carrier (such as NADPH), where they cannot cause damage. 2) The field of developmental biology (which studies how an egg forms into a mature organisms) has a complete understanding of how some simpler animals develop - notably C. elegans and Drosophila. These scientists also have a good understanding of the mechanisms which underlie the development of more complex animals, such as mice and humans, although there are still some holes. All evidence present to date show that the genes which lie within our DNA, and the proteins those genes encode, are sufficient for the development of all living organisms. 3) The process by which salamanders regrow limbs is completely understood. The process by which salamanders grow limbs is the same process used by embryos to develop limbs for the first time. The genes responsible for this process, as well as the metabolic processes which allow it to occur, have all been well described. They will be described in detain in any introductory developmental biology textbook, something which you (or Dr. Becker) have obviously never read. 4) If you want to understand how these processes work, you will need to sequences, and very little knowledge about the genes involved in development. Today Dr. Becker is still dead wrong, and as evidence against him we have the entire gnomes for several species, and a near-complete understanding of the genetic and biochemical processes involved in animal development. Here's some starting material. Try reading it before you come back and spout off some more nonsense: The interactive fly (genetics and development of Drosophila): http://sdb.bio.purdue.edu/fly/aimain/1aahome.htm Drosophila Genome & Development: http://www.fruitfly.org/ C. Elegans Genome & Development: http://elegans.swmed.edu/ Mouse Development Atlas: http://genex.hgu.mrc.ac.uk/ Good textbooks: Developmental Biology Text (introductory): Developmental Biology, 7th edition. By S. Gilbert. Genetics text (has some developmental genetics): Genes VII. By B. Lewin Basic Biology (which you obviously need): Biology, 6th Edition. By N. Campbell. Basic Biochemistry (ditto): Mathews Biochemistry Bryan |
