To me this definition misses the important distinguishing feature of Muller's ratchet. A 'fixation', or click of the ratchet, isn't of individual deleterious mutations, but rather loss of genomes with the fewest deleterious mutations. This means that Muller's ratchet does not necessarily require fixation of individual genes. Suppose capital letters represent 'wild type' alleles, lower case letters the corresponding deleterious mutations, and diffent letters of the alphabet correspond to different loci. Fixation of the deleterious mutation at the 'C' locus, for instance, might occur if all individuals in the population had one of the following (multilocus) haploid genotypes: ABcDEF *or* ABcDeF *or* ABcDEf On the other hand, one click of Muller's ratchet might characterize the situation where individuals have at least one deleterious mutation, even though a particular deleterious mutation is not fixed in the population: ABcDEF *or* ABCDeF *or* aBCDEf The central aspect of the genetic system allowing Muller's ratchet to operate is the lack of recombination. When recombination occurs, it's easy to recover genotypes free of mutation from a population such as the second example. For instance, recombination between the 'C' and 'D' loci of the first two genotypes would lead to ABCDEF. In the absence of recombination, conditions allowing for the operation of the ratchet make recovery of the least loaded genome through mutation unlikely. It's a ratchet becuase of the inexorable accumulation of deleterious mutations, leading eventually to species extinction. > When this occurs in small populations > genetic variation is lost and can only be regained at that locus by > mutation or migration of new alleles.

Well, this is NOT Muller's ratchet. Muller's ratchet is the accumulation of recessive deleterious mutations in an asexual population. It occurs because these mutations are never combined together in a homozygous state.

It refers to a chromosome with no recombination, in which if you get into a state where all copies of the chromosome have at least one deleterious mutant (so that you didn't lose genetic variability at each locus, but you lost the by drift the chromosome type that had no deleterious mutants), then one can regain the no-mutants chromosome only by back mutation, as recombination is not available.

Asking about ability to evolve incorporates questions about 2 somewhat different concepts. First, evolution occurs by selection among RANDOMLY-generated mutations. Until a mutant appears which varies in the trait in question, there can be no evolution, no matter what the selective advantage to such a trait. Some plant species have not been "lucky" enough to happen on a set of mutations which will help in metal tolerance, at least not among members of the species who are in an environment in which tolerance is selectively favored. The second aspect to your question is about ability to evolve in a particular direction even when the necessary genetic variation becomes available. Those populations showing metal tolerance do not occur off-site, implying that they have lost other competitive abilities in the process of gaining competitivity in the presence of metal contamination. In other words, there was a trade-off of ability. Therefore, "able to tolerate metal contamination" means "able to afford to lose competitive ability in the absence of contamination". The overall direction of evolution will be determined by the relative importance of these competing factors, in the local population and in the species as a whole.

The main idea of this theory is that killed creatures transmit by unknown way all information they gathered during their life to the survivors of the same species at the moment of death. That is, each individual participated in essentially important for evolution information connection between generations not only transmitting the genetic information received from parents to their offsprings via DNA but also transmitting all information about environment, gathered from the first moment of life to the last moment of death, to all survivors of its population. (If we suggest that information is not just a measure but a fundamental category like matter and energy, then it becomes understandable that with death of living creature all information about its life can not just disappear - it could change its form but must continue to exist.) Thus, gathered by each ever lived individual of a biological species information does not vanish but accumulates somehow as an "information fund" of the species and takes an important part in life of progeny determining equally with genetically inherited information the embryonic development, reproduction, instincts, behaviour, etc. According to our theory that part of the whole transmitted from killed to survivors information which is received at the moment of violent death has the most important significance to process of adaptation of biological species to the environment. We think that transmission of this information makes population protecting mechanisms work. The first level of protection is preservation of population numbers via changes in reproduction: this information can directly influence the reproduction rate of survivors increasing it. The second level of protection is a level of adaptation via changes of characteristics: information about causes of death received from killed individuals influences the mutations that results in changes of genetic characteristics in next generations leading to adaptation to this killing factor. To prove the link between reproduction rate of living creatures and violent death within a population we have conducted a series of experiments on laboratory animals. The experiment pattern was extremely simple similar to that of well-known experiments aimed to study population self regulation at the level of numbers in which populations of laboratory animals are exploited as they might be by predators. In these experiments we observed the reproduction rate in several identical groups of animals from which the equal numbers of animals were removed. The difference in our experiments was that the animals from the test group were killed and then removed while the animals from the control were just removed (An attempt was done to model what occurs in nature). Results proved the theoretically predicted increase in reproduction rate in the test groups. From the point of view of our theory it would be possible to give new explanation to some evolution theories and well known facts. According to Malthus theory (which still seems to be actual nowadays) human populations have the capacity to increase at a much greater rate than food resources and there are three major factors holding human population growth in check: war, pestilence and famine. Then why is the reproduction rate of human animal far more higher than for example that of lobsters that human use as a food? Maybe the real cause is that people kill each other in huge numbers and lobsters not? Thus, maybe we should stop killing each other and start killing lobsters - not to take them out of their environment but kill them in there next to potential survivors of their population, like we kill rats? According to theories of Lamarck and many of his successors characters changes wrought by the environment during the life of an individual become hereditary and thus can be transmitted to the next generation. This mechanism would explain a lot of direct adaptations to environment but it can not be theoretically substantiated from the point of genetics and can not be experimentally confirmed. Then again, why does giraffe have got a long neck? Maybe because a lot of short-necked ancestors of modern giraffe stretching their necks to feed on leaves high in a tree died from starvation and transmitted to the survivors information that long neck could save them from extinction - and this information was the real cause of genetic mutation which changed the length of neck in descendants? In the same way it is possible to explain the results of well known experiments of John Cairns and Barry Hall. This experiments were conducted on bacteria. They demonstrated that when bacteria are deprived of certain essential nutrients such as amino acids tryptophan and cycteine, they are capable in this extremely hostile environment of giving rise to descendants capable of synthesising their own nutrients. Bacteria were mutating and these mutations were not random but directed by the needs of the organism in the direction of being able to synthesise the necessary nutrients. Suggesting that killed bacteria transmitted to survivors information about cause of death - absence of amino acids tryptophan and cycteine, it turns quite obvious why it is these mutations that provide capability to synthesise the necessary nutrients occurred in descendants. I attach the description of two series of experiments conducted by independent researchers on silkworm and laboratory rats.(The latter experiments have not been published so I attach the copy of certificate ). Those who will be thinking on ethic side we ask to read the posting Ethics and Ecology in sci.bio.ecology newsgroup. Experiments on silkworm were conducted by professor Sarkisian C.M., Institute of Zoology, Academy of Science of Armenia. Genetically identical offsprings of nonfertilized female were divided equally in experimental and control groups, 40 individuals in each. All development stages up to pupal stage passed with no interference. Before pupating within 4 days one caterpillar was killed by needle daily in experimental group and one was removed from control alive. Emerging butterflies were prepared and the number of laid eggs was counted. The number of eggs in experimental group equalled 10-35% more than in control. ----------------------------------------------------------------------- copy translated from Russian CERTIFICATE This is to certify that based on the pattern suggested by Ignat A.Agadjanian experiments were carried out from April to June 1989 by the Department of Epidemiology, Yerevan State Medical Institute to test the conception proposed by him claiming that dying creatures releasing signals which increase the reproduction rate in survivors within a species. Experiments were carried out on 835 identical (weight, age, etc.) non-linear white rats (600 females and 235 males) equally divided into experimental and control groups. Within 7 days one individual was killed daily by 3% phosphide of zinc (dosage equals to that used by sanitary epidemiological services for pest control) in experimental group and one was removed from control alive. Experiments results with statistical accuracy equal to probability of casual results below 0.001 showed that although other conditions were maintained equal, compared with the control the number of pregnant females in experimental group was 2.9 time more, the number of offsprings - 3.45 time and the number of offsprings against one killed individual - 10 time. Conclusion: Investigated phenomenon can be successfully applied in the economy, in pest control and in husbandry in particular.

We are sure that given possibility to continue these experiments on laboratory rats in many generations for a longer period (compared with the time passed from first using of DDT till first reports about revealing a resistance to it) there will be obtained very important results on the level of understanding the evolution mechanisms: rats will have genetically hereditary resistance to phosphide of zinc though their ancestors had never ever have direct contact with this chemical. Analogically, continuing the experiments on silkworm for a rather long period of time it might be possible to receive a population of silkworm with caterpillars genetically protected from being killed by needle. Analogically, it might be possible for example to develop frost- resistant lemon-trees... -- AROUTIOUN AGADJANIAN From owner-population-bio@net.bio.net Thu Nov 17 22:00:00 1994 Path: biosci!ROSEWORTHY.ADELAIDE.EDU.AU!gstarr From: gstarr@ROSEWORTHY.ADELAIDE.EDU.AU (Gary Starr) Newsgroups: bionet.population-bio Subject: Re: POPULUS Date: 17 Nov 1994 17:23:31 -0800 Organization: BIOSCI International Newsgroups for Molecular Biology Lines: 17 Sender: daemon@net.bio.net Distribution: world Message-ID: References: NNTP-Posting-Host: net.bio.net The ftp address is ecology.ecology.umn.edu and it's in directory pub/populus.

However, I realise that there are mechanisms in Nature which are beyond any imagination. I find it quite interesting to hear of research embarking on 'esoteric' domains. Yet, there are quite a few sets og reasoning which I find irritating and illogical. I do not infere that the experiments conducted are untrue - if these are the results that have been obtained, no problem. It is down to research bodies to determine whether the experiments were conducted in a manner which allows them to be taken seriously. I am happy enough about startling new insights. However, it is some of the implications which I find difficult to digest. 1) If information is passed on to the rest of the population on death, so that the population as a whole benefits of the experiences made, how come that the human race does not improve, and learn of mistakes? Look at history, and you will find that there have always been idiots, and worse, on the face of the earth. and there will always be. Unfortunately. Your hypothesis, however, certainly implies that we LEARN of the experiences of others? 2) If information is transmitted on death, why does it make a difference whether death happens in the presence of other members of this species? What about death in proximy, but the organisms cannot see ar hear each other, or everybody is asleep? Certainly it should not make a difference where somebody dies if it is about the transmission of vibes. What circumstances of death make the information untransmittable? I am referring to the lobsters. 3) the eternal presence of information. alright, so matter does not cease to exist. And we are in the era of information technology, so we all know that information exists, even though you cannot touch it as such - but you can buy it! Philosophy is non-existant interms of matter, but you can buy a book on the topic. On the other hand, you can burn all the books, or for that matter, press delete, and the information is gone and cannot be retrieved. Do you think that it then is still somewhere in the air? If you dispose of matter, there will always be some traces however small. but is this the case with information? You can argue that if someone writes a book and then destroys it it is likely that somebody else knows that the author has at some stage been writing a book, even though it exists no longer. This would be a trace, but surely circumstances do not always permit this? 4) The information is transmitted to the other members of the species. So when did lions and tigers stop to receive information from the same individual? I have no problems with acknowledging that they are two different species, even they can breed hybrids. But how does the information determine to whom it should 'go' and to whom not? Is it like with receivers in immunology? Suddenly the lions could not receive the information any longer, because the tigers had evolved into a seperate species with specific receivers? It is a problem similar to the reincarnation thing. If there is reincarnation, when in the history of the earth did the human race decide to reincarnate? Or do fish and worms reincarnate as well? I can fully accept that there can be circumstances which in some way or other influence the intrinsic rate of increase. but I do have problems with the kind of implications that have been made. Science is in many ways too much favouring certain points of view, and ignoring phenomena which are unperceivable. But I find it difficult to take some of the alternatives very serious. Even though I would quite like to!

Support Address Location --------------- -------- biosci@daresbury.ac.uk Europe, Africa, and Central Asia biosci-help@net.bio.net Americas and the Pacific Rim **** SEARCHING BIOSCI ARCHIVES **** The easiest way to search the BIOSCI archives is to use gopher software and connect over the Internet to net.bio.net, the U.S. BIOSCI computer. We maintain three indexes which are searchable from the main gopher menu on net.bio.net: (1) an index of all BIOSCI postings; (2) an index of individual journal article references from the Table of Contents postings on the BIO-JOURNALS newsgroup; and (3) an index of BIOSCI users including regular mail and e-mail addresses, phone/FAX numbers, research interests, and newsgroup participation. E-mail users can search the BIOSCI archives by using our waismail e-mail server. For instructions send the message help to waismail@net.bio.net. Leave the Subject: line blank (anything entered on the Subject: line is ignored). WAIS software can also be used to search the archives as described in the BIOSCI FAQ (see below). Finally, the BIOSCI archive files are accessible by anonymous FTP to net.bio.net [134.172.2.69] in the directory pub/BIOSCI. **** BIOSCI FREQUENTLY ASKED QUESTIONS (FAQ) SHEET **** New users of BIOSCI/bionet may want to read the "Frequently Asked Questions" or "FAQ" sheet for BIOSCI. The FAQ provides details on how to participate in these forums and is available for anonymous FTP from net.bio.net [134.172.2.69] in pub/BIOSCI/doc/biosci.FAQ or for retrieval by gopher to net.bio.net, port 70. It may also be requested by sending the command info faq in the body of an e-mail message to the Internet address biosci-server@net.bio.net. Please do not enter the info faq command on the Subject: line of your message since the e-mail server ignores text on the Subject: line. The FAQ is also posted on the first of each month to the newsgroup BIONEWS/bionet.announce immediately following the posting of the BIOSCI information sheet. **** BIOSCI USER ADDRESS DIRECTORY **** Please take this opportunity to add your name and address information to the BIOSCI User Address Database if you have not already done so. Below is the address form that we would like each reader of the BIOSCI/bionet newsgroups to complete and return if you would like to be listed in our database. The database serves as a directory that enables biologists, who are currently using (or even just reading) the BIOSCI newsgroups, to look up e-mail addresses and other information about our users. The address database is reindexed nightly for WAIS, waismail, and gopher access. If you have access to gopher, connect to net.bio.net to search the database. If you have access to WAIS, please use our WAIS source biologists-addresses.src. If you are not on the Internet, please use our waismail server (send the word "help" to waismail@net.bio.net to get instructions; any text on the Subject: line of your message will be ignored, so put the help command in the body of the mail message.). Please carefully follow the instructions for completing the form below and return it to either of the following two addresses (whichever is more convenient for you).

But how? We can not suggest that it is obvious and knowable (from the point of view of our present knowledge) process - otherwise we simply would know about it. But we can try to highlight the indirect evidence of this process. During 20 century have been killed more people, than during such period of time in previous history of mankind. At the same time in 20 century has been done a lot of scientific discoveries and civilisation made a gigantic qualitative leap in its development. What is this if not a global process of learning using experience of unconscious cognition of nature of those who lived and died. But as a result of such mass killing we come across huge problems: overpopulation and ecological crisis. The number of population on Earth is already so big that gained level of knowledge is not sufficient to solve these disastrously dangerous problems. The only simple solution - to stop killing. 2) Transmission of information from dying creatures to survivors is fully materialistic, physical process, which can be investigated thoroughly from strictly scientific positions. Before it we can only make suggestions. If the way by which we kill certain animals and insects somehow models the death caused by predators we can await for reciprocal increase in reproduction rate. Thus it is quite possible that the main reasons why lobsters' reproduction rate in response to our killing does not increase are: 1) we kill lobsters not in their environment; 2) we kill them far from other individuals of their species. The same reasons - environment and distance probably predetermine the fierce response of nature to our attempts to control the numbers of rats populations. 3) What does that mean - information in a book? When a man in the court before answering the questions (and in other similar situations) puts his hand on the book and pronounce certain words we consider this situation as a ritual. But what exactly in the processed piece of wood (according to some superstitions) can influence the man who is touching it? - The information that this book contains! Thus the information connected with the matter can principally change the physical characteristics of it. And when such a subject , for example a book, vanishes, the matter does not cease to exist and so does not information - they both just change their forms of existence.(One of hypothesis of our theory is about the role of catalyst in chemical reactions. We think that on the surface of catalyst the reverse reaction is taking place during which emerging small quantities of final product disintegrate into original components and information about structure of final products is released and transmitted to original components what serves the key role for increasing the speed of direct reaction.) 4) Our theory is not a ready package of new knowledge which has got answers to all possible questions. At the present moment we consider it as an useful tool which can give us possibility to examine all data gathered before from completely different point of view. And asking such questions about why information is not transmitted from tigers to lions and when did it start we potentially are making first step toward understanding of very important problem of nowadays - why pests against which we fight increase their reproduction rate and acquire resistance to pesticides - i.e. why information from killed pests of certain species is transmitted to survivors of the same species and is not transmitted to animals or insects of another species which are similar to those we fight and what is possible to do at all to avoid it. -- AROUTIOUN AGADJANIAN From owner-population-bio@net.bio.net Fri Nov 25 22:00:00 1994 Path: biosci!agate!howland.reston.ans.net!pipex!uunet!newstf01.news.aol.com!newsbf01.news.aol.com!not-for-mail From: wymermd@aol.com (Wymermd) Newsgroups: bionet.population-bio Subject: Re: Aids Epidemiology Date: 25 Nov 1994 21:25:05 -0500 Organization: America Online, Inc.

There does seem to be a bit of a down-turn in the total of new cases reported in the US for the last few years. Still, the emphasis for prevention has to be on behavior modification. The majority of new cases in the US (classified by type of risk behavior) are still driven by MSM's (Males who have sex with males) and IDU's (Intervenous Drug Users). Heterosexual sex is a rising proportion, but still dwarfed by the former. More than 50% of new cases continue to originate from White Male Homosexuals. A common denominator would seem to be sodomy (male on male or male on female) but no one talks about this since it has been accepted by many as legitimate or acceptable behavior.

As a result, neural network models seem unable to capture what I am trying to look at. However, it has occured to me that using the much-studied formal approach of population systems models, I could look at neurotransmittor densities in relation the stimuli which influence production and decay/reuptake rates, even with elaborations such as mutually-inhibitory physiological systems could be modelled with some of the kinds of formal frameworks used for competing species.

The database will be high school and non-biology college oriented. The idea is to create a collection of good questions that can't be found in general textbooks and that are different from just textbook phrases put into the interrogative mode. If you have any good thoughtful questions you use in your teaching or that come out of your research or environment protection practices I would greatly appreciate if you share it with us. Please e-mail it to me or send by mail (L.Yampolsky, Section of Ecology and Systematics, Corson Hall, Cornell University, Ithaca NY 14853). The project is Russian-based and Russian funded; so currently the language of the database is Russian. Eventually we'll produce an English version. We were also originally planning for a wider database "Biology in Qs and As", but the funds go so far only for ecology. We include both essay-type and multiple choice questions; the former preferred. There is a particular need in practical questions dealing with real environmental problems or contradictions, particularly those that give an example of a solution of the problem. If you are interested in contributing, please send your questions, preferably with a short answer and the information on the author or copy right holder of the question (if any) and on the experience in using the question in teaching. All contributions will be acknowledged in the database. Large contributions may be (very modestly) paid for. Thank you very much in advance.

You spin the cylinder once, point it at your head and fire. Risk at that point is 10%. But how about the subsequent spins and firings? If you keep spinning and firing, sooner or later you will blow your head off. Would be interested in knowing how to figure the risk for 10 events, 20 events, 50 events, etc. Plus would like to know how to figure the number of events necessary to reach 50% risk, 90% risk, etc. TNX, Bob Wymer, not good at math.

You should consider joining SSE (Soc. Study Evol.) and SSB (Soc. Syst. Biol.) and SMBE (Soc. Mol. Biol. Evol.). The membership rates for students in SSB are extremely cheap (US$ 12.50). I don't know about the others. Also, you get the journals with these memberships in these societies. Moreover, the SSB/SSE (&SMBE?) joint meeting is in Montreal this summer. Given that your interests appear to "micro"evolutionary, these seem to be the most appropriate. If they veer to the macroevolutionary, you might want to consider the Willi Hennig Society too. -- Mark E. Siddall "I don't mind a parasite... mes@vims.edu I object to a cut-rate one" Virginia Inst.

The calculation goes as follows: The chance of failing is 10%. Therefore, the chance of not failing is 90%. Therefore, the chance of not failining in two indepdent samples is 81% (.9 X 9). Therefore the chance of failing is 19%. the general model is as follows: 1 - (1 - p)**N where p is the failure rate of a single try, (1-p) the success rate of a single try (1-p)**N the chance of succeeding after N tries 1 - (1-p)**N the chance of failing after N tries. See how (1 - p) < 1 goes to zero as N goes to infinity? Says after a large number of tries you will blow your head off!
