I think the definition of " cause " is part of the problem. A poppy seed " causes " a poppy, but only if it's planted in fertile ground and receives appropriate moisture, heat, light, nutrients, etc. At any point the process might be aborted by environmental factors, or even a defect in the seed itself. Some seeds are extremely adaptable and will sprout in most soils and under nearly any conditions. We call these " weeds. " Others require highly specialized conditions to complete their life cycle. That's how pathogens are, too. They are all different, just as all hosts are different. How they spread, how they get a foot hold, and the course they take after entering the host, will vary. But to people who define " cause " as meaning, " In every single circumstance when you expose any host to that pathogen, an identical course of illness will result in all hosts, " then no, there is no such thing as a pathogen that " causes " disease. The problem with that is that, as I pointed out before, it's a straw man argument.

I don't know much abou the HIV issue, but it isn't relevant to my point. My point was that immunity or lack of immunity to a given disease can be dependent on genetic and other circumstances dictated by past exposure, and since Price did not demonstrate that in any given resistant population that they were resistant to newly encountered diseases, his research doesn't conclusively show that dietary soundness can confer immunity to newly encountered diseases.

Well this is what I first had in mind but I thought I would refresh my thoughts before bringing it up. But yes, I would agree. What I was saying, of course, was that in the instances in which primitives were immune to any given microbe (like tb, for example) in NAPD, there was no evidence that this was a newly encountered microbe like experienced by native populations all over the Americas.

Ok, since offered it, let's start with the natives of the Americas all over. What is your response to the interpretation that the mass die-offs upon exposure to new microbes reflects the capacity of some microbes to which a population has had no training in immunity to overcome even a very healthy terrain? Moreover, why were the Europeans immune to the very same diseases? Were the Europeans in better health, eating better diets, from better soil? There are other examples. One interesting example is the Kung San of the Kalahari. Their food is nutritious enough that they are immune to tooth decay, yet they are not immune to the venereal diseases and some other infectious diseases that they have encountered from contact with Europeans. Perhaps there is some threshold for soil quality and dietary soundness that establishes immunity to tooth decay that is lesser than the threshold required for immunity to infectious diseases, but such hasn't been demonstrated, and an example of a population immune to tooth decay and and not immune to infectious diseases clearly shows that one can differentiate the two, and contradicts the general principle of the two going hand in hand expressed in NAPD if one is to assume the unjustified conclusion that in every instance immunity to any given infectious disease will follow exactly the same model as did immunity to tb for the Gaelicks for example. > > Weston Price left no doubt as to the existence and identity of > > activator X.

A positive reading on the > Yoder test does not guarantee any antirachitic property of the > substance at all, which is why turpentine and mineral oil test high in > " activator X " but have no antirachitic property. Let me further point out that the antirachitic properties, as is clearly and abundantly established, are due to vitamin D3 in all species and are also accomplished by vitamin D2 in some species. You backed out of this conversation the last time we had it, in which, in my view, I reasoned compellingly that a) NAPD fails to show conclusively that vitamin D is incorporated within the X Factor complex any more than is vitamin A and that Price didn't conclusively differentiate the X factor from vitamin D3, or for that matter from combined effects of vitamins A and D. (I admit full well there is evidence suggestive of a third factor, but this is different from a rigorous separation of the various factors that is standard in science). If you recall, you had argued that it was sufficiently differentiated from D3 by being differentiated from D2, which was marked by a coincidental error in believing that D3 is not a product of animal bodies, when, in fact, it is *exactly* that. Finally, Price did not identify the X factor. Vitamin D is identified; vitamin A is identified. We know their molecular weights, their chemical structures, how they are synthesized, how they are degraded. None of this is done for the elusive activator X. All of this is layed out abundantly in thousands of studies in great detail for the other vitamins. NAPD is a great start in suggesting such research into the effects conferred upon by " activator X " but it is a long way from having accomplished such identification.

In pointing out a technical flaw in her analogy, you are giving more strength to its power to demonstrate the principle: if different " weeds " all have their own ideal " terrain, " and, analogously, various microbes all have their own ideal " terrain, " then one cannot necessarily establish a terrain that is invincible to all microbes. Pathogens, like beneficial organisms, and like host species, and so on, evolve over time, as well. It would be beneficial for a pathogen to evolve the capacity to tolerate otherwise harsh conditions. If a pathogen evolves such a capacity to inhabit a terrain that generally is inhibitive of pathogens, then such a terrain would cease to be inhibitive for that particular pathogen.

Guest guest Posted January 18, 2006 Report Share Posted January 18, 2006 >> this is another example in nature of the terrain being everything and the seed being nothing. The plant does not create the terrain, the terrain determines the seed that will germinate and grow there. << If the seed isn't there, it won't germinate and grow. And a turnip seed can't grow into a peony. The seed AND the terrain are both important. That's my whole point. We naturally want it to be all terrain, because that gives us a sense of control. That's just human nature, to decide that we can ward disease and tragedy off with proper diet and lifestyle, or by chanting in a field at midnight, or shoving a virgin into a volcano. But it's still magical thinking. Microbes do exist, and sometimes they cause disease. No living creature is at peak health every single moment of his or her life. It's impossible. Disease resistance is something that will ebb and flow for every individual, and even the strongest, best-fed, most dazzlingly healthy creature can succumb to something in a moment of weakness, fatigue, or sleep deprivation. We're only fooling ourselves if we believe otherwise. Does that mean that terrain means NOTHING? Not at all. The " seed is all " folks are also blind and wrong. It goes both ways. It's the whole complex system that matters, and things we can do that influence the system, not one factor in isolation.

Dennis Like all other known forms of life, pathogens store the information necessary to reproduce in their DNA. Each time the pathogen reproduces, it makes one copy of its DNA to give to each of its offspring. Occasionally an error is made when copying the DNA. This results in a mutation, meaning that the new pathogen(s) will be slightly different from the old ones. If this mutation is beneficial--that is, if it gives the new pathogen a better chance of reproducing--the mutation will become more common due to the pathogen and its descendants reproducing more frequently. Thus, over time, pathogens tend to become stronger and better able to overcome our defenses against them. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 18, 2006 Report Share Posted January 18, 2006 That's a superficial contention, and doesn't mean population growth is attributable to birth rates. As the /maquerequere /in Johannesburg attests, South Africa had an extremely liberal immigration policy, but now troops are stationed at the Limpopo to turn back the tide of destitute Zimbabweans. There is a horrible infant mortality rate, attributable to the abhorrent number of babies born HIV+, and birth rates are on the decline. The government continually makes adjustments to population statistics, accounting for the staggering AIDS death rates (a second " with AIDS " number is usually presented with regular populations predictions). Population statistics for Zimbabwe indicate that the death rate is now higher than the birth rate. soilfertility wrote: >These >tests are not even used in Africa where the syndrome AIDS is diagnosed >from clinical symptoms (lol). >Check what happened to the population in South Africa in the last >census.

I don't know you nearly well enough to count on your ability to discern truth, but that's really not the point. It's very hard to come to accurate conclusions when prevailing theory is incorrect. It's taken me years to learn as much as I have about health and nutrition -- and I still have vast realms of information to learn and doubtless plenty to unlearn too. So I'm not making any kind of pejorative comment about your intelligence or ability by not placing much weight on a casual conclusion borrowed almost entirely from other people without much independent research. The fact that they're not possessed by religious fervor isn't really relevant, because what religious fervor there is contributes to the informational and economic ecology in which skepticism has difficulty flourishing. It's the same with nutritional theory. There are some people with irrational convictions and others who just accept what's presented without demonstrating any fanaticism themselves, but the overall ecology makes it difficult for competing theories to get a foothold. And all that said, maybe Duesberg is FOS. I haven't looked into it. I'm just not inclined to automatically trust the mainstream medical establishment when it's given us the cholesterol theory (and indeed an entire through-the-looking-glass systema of nutrition, physiology and health) and garbage like bird flu hysteria. - Quote Link to comment Share on other sites More sharing options...

And in addition to what said, the proportion of individuals with any given preexisting gene in a population will change over time in reaction to the environment. Although in this particular case, unlike the one offers above, the property conferred by a gene whose proportion in the population is changing might not be something fundamentally new, since microbes must act at a certain critical mass to exert some effects, a sharp environmental change could cause a mass reproportionment of the genes in the population, such that at the level of the population, the property is new, simply because a critical mass of the microbes now possess it, their competitors in the population having been weeded out.

I read your post and find your analysis of weeds, plants, and soil, totally sensible and consistent. However, your analogy fails in certain observable ways. First to note what should be evident, it is fraught with the danger of serious error to generalize even between mamallian species about the effect even of a single chemical, and the magnitude of that danger runs much deeper when comparing, for example, humans to birds. Yet you are freely generalizing very broad concepts between not even plants and humans at this point, but even soil and humans. While there may be valualbe points to be made by using such analogies, the fact is that we know a lot about human immunology, and it doesn't work the same way as plant immunology, and it certainly doesn't work the same way as soil " immunology, " if you want to call it that. One clear difference between human immunology and soil " immunity " to " weeds " is that both past exposure and genetics can contribute to the immunity to specific diseases. As long as the seeds are somewhat available, you may go back and forth over time to the same cycles of plants as the conditions of a soil change, whereas outbreaks of certain types of diseases in human history often cause a massive dieoff and then disappear, and the next big strike is with a *different* organism, because those who are left have acquired immunity. Look at the black death for example. Yes, there were agricultural misfortunes around the time it came about, but after it killed a third of Europe, it didn't come back when soils the world over went through much trouble, lowering the immunity of the people. Or look at how the Europeans brought all kinds of diseases that ravaged natives of the Americas all over. Even if some of the native groups had declining skull sizes since Columbian times, and even if some of them or even all of them didn't have perfect diets, it is difficult to conceive that the Europeans diets could possibly have been better, since the Europeans quite clearly wrecked the soil while the natives tended to maintain it, or at least many of them did, in many areas where they hunted and left the woods rather than cutting them down. Yet 65% or more of the natives were killed off extremely quickly by infectious diseases brought by the Europeans, while the Europeans had immunity. Because the Europeans had specific immunity to those diseases. This doesn't happen with soil and weeds. Soil does not have B cells that provide " memory " to the immune system that, having experienced a " weed " before can provide specific immunity to that weed. In some ways there are analogous elements, but they are very different processes in the majority of ways and stretching the analogy can easily lead to unjustified conflations.

Guest guest Posted January 19, 2006 Report Share Posted January 19, 2006 Dennis, > Is this info below your definition of evolve? THE definition of " evolve " is to change over time. Cultures evolve; the genetics of populations evolve. Brand new ideas or technologies in a culture can contribute to its evolution, but are not necessary for it to evolve; mutations in the genes of a population can contribute to its evolution, but are not necessary for it to evolve. The ebb and flow of *proportions* of preexisting genes in a population in response to environment is genetic evolution, even though it does not require mutation. For example, if a given species of moth, the individuals of whom may appear black, white, or somewhere in between, is exposed to different environments at different times or in different areas, where they may be more likely to be against a light background at times, and a dark background at others, that population's color will " evolve " according to the environmental circumstances, because the moths who stand out more will get preyed upon more and therefore get eaten and die more. So if the environmental background is very light, the darker and black moths will stand out and die more, leaving more room for the very light moths who blend in well to reproduce, and vice versa. This is evolution, is not necessarily directional, and does not require mutations -- which do, verifiably occur, which is a separate point. Likewise, the characteristics of the individuals of a bacterial population are not uniform. Perhaps, for example, 1% of them, Variant-Beta secrete adhesion protein x, protein-digesting enzyme y and toxin z that allows them to cause a certain effect a in a host, but that the critical mass required to secrete these things and actually *cause* that effect is 10 population units. These 1% also have a gene that makes them resistant to Antibiotic 1. Most of the 99%, whom we will call Variant-Alpha, neither have these effects nor are resistant to Antibiotic 1. Assume that there is a crowding effect, where in the presence of Variant-Alpha, Variant-Beta is kept in check at 1% of the population. Say 100 population units *total* infect a host, of which only 1 population unit (1%) is Variant-Beta. If a dose of Antibiotic 1 is used, it will cause the population to " evolve " because the *proportion* of genetic variants in the population will change. The longer that Antibiotic 1 is used for, and the higher the dose, the more that Variant-Alpha will be combatted while Variant-Beta will not be affected. By removing the crowding effect or whatever mechanism by which Variant-Alpha keeps Variant-Beta from becoming more than 1% of the population, thanks to the changing environment provided by Antiobiotic 1, Variant-Beta will become the dominant variant in the population. Thus, room is made for Variant-Beta to expand beyond the threhold of 10 Population Units. Once that threshold is met, the specific toxic effects occuring in the host are different. Thus, the specific toxic effects change -- evolve -- in response to environments, even by mechanisms that do not require mutations. >Where did you > get all that info? What does it mean??

" HOW you going to change my genes by sending me to the > north pole or the moon? It isn't that simple is it? You are an individual, not a population. Individuals do not evolve; populations evolve. If you are interested in the subject, I suggest you pick up a basic college biology textbook and read the chapter on evolution. I know you work in a lab so maybe you have seen this information before, but, while I'm sure your totally capable, you don't seem to be familiar with the basic evolutionary concepts. You might also want to check out http://www.talkorigins.org. I don't mean that to be remotely insulting, but a basic introductory textbook entry on it might be able to explain the introductory basics to evolution more concisely than me. Not that I mind you asking. > MAYBE all the > microbes need is information (from the designer?) " to exert some > effects " . Dennis The question isn't why they exert some effects. It's why those effects can evolve over time within a population. Natural selection is a much simpler explanation, is observable, and is self-evident. Moreover, one would expect a Creator to be quite capable of creating a universe that can flourish itself, and surely one would consider the creation of something with creative capacity itself to be a more impressive creative feat than the creation of something that needed to be babysat and tinkered with everytime a change was required. One would also think said Creator wouldn't be insecure about evidence that his creation unravels life with its own intricate processes would somehow nullify his creative power when it would so obviously exalt it. In any case, it is a very simple and elegant explanation that environments filter populations for the individuals best-suited to that environment. It is a basic principle of basic logic that this *must* happen, because we know that when something dies, it ceases to exist. It is that basic and fundamental. You can question exactly what the implications of natural selection are and exactly to what extent they are responsible for the entirety of life itself if you choose, but one can't be reasonable and simultaneously deny the self-evident fact that natural selection is an operative force in the genetic evolution of populations.
