As every child in our public school system knows, all critics of neo-Darwinism are religious fanatics. Except those who aren’t, such as University of Madrid biologist Maximo Sandin, whose dislike for Darwinism seem to be as much based on its association with capitalism (here) as with its inconsistency with the fossil record and other evidence.

The theories which have been proposed to replace neo-Darwinism tell us something about the respect that many biologists have for the official version. Sandin’s alternative theory involves viruses and bacterias (he refers more or less approvingly to Alfred Hoyle’s “Evolution from Space”). The following is excerpted from one of his essays , an English translation is here .

Viral and bacterial response capacity to environmental stimuli would justify the inevitably rapid and far-reaching changes shown in the fossil record, forcibly needed due to the complex interrelation between tissues and the whole organism. And their “infective” character would render these changes possible in a considerably large number of organisms simultaneously. On the other hand, this infective character could be implicated in mass and selective extinctions, often coinciding with episodes of environmental disruption, events that would therefore be part of the evolutionary process.

In this context, natural selection, whose lack of creative power has been previously discussed, would be relegated to a secondary plane in the evolutionary process, being occasional and void of meaning as a mechanism for evolution. Competition would no longer be the driving force behind evolution, since new species would arise and mature as a whole.

Bob O'H, thanks for connecting me with Zachriel on antievolution.org. I have a lot of respect for Zachriel, he is clearly knowledgable, he is well spoken, and willing to look at real challenges. He certainly is on the other side of the fence, however he is one that I wish was not banned here. Uncommon Descent is too quick, in my opinion, to remove descenting voices. Zachriel has started a new thread: http://www.antievolution.org/cgi-bin/ikonboard/ikonboard.cgi?s=47d46d5d9419131a;act=ST;f=14;t=5449;st=0 You may want to join in on the conversation.bFast

PannenbergOmega Hmm, the article by Sandin that I link to above gives Alfred Hoyle as the author; from Google it appears you are right, though I did find 2 more places where the author of "Evolution from Space" is listed as Alfred Hoyle, one in Spanish and one which also refers to Sandin. So not sure what the deal is, maybe someone who cares more than I do can investigate this further.Granville Sewell

Bob O'H, "bFast @ 8 - you’re illustrating a well known problem, genetic drift." Yes, I am suggesting that the new allele will fail or succeed almost totally because of drift, it will not be directly selected for. Bob O'H, "Drift is a large factor in small populations" Are you suggesting that if the population is large enough natural selection will be able to select for the advantageous allele? Show me the math.bFast

bFast @ 8 - you're illustrating a well known problem, genetic drift. With a population size of 5, the relative fitness has to be very large to have a visible effect. Drift is a large factor in small populations, so even alleles which reduce fitness can become fixed. Actually, there's another aspect in this. Any new allele that enters a population will start with a low frequency, so its dynamics are essentially stochastic. The upshot of this is that many mutations will not invade a population, they will go extinct first.Bob O'H

I am working on my own simulator (though I seem to do mostly other stuff). However, it is written in painfully optimized C++. It will take Dawkins' "Methinks that it looks like a weasel" program and broaden it to its limits. Do you really think that we can get to a 50,000 character phraise by honest random mutation and selection in a population of 10,000? I personally don't think that the program will get there once a genuine noise-level is introduced.bFast

[Off-topic. Dr. Sewell, sorry for stepping on your post.] bFast, Several weeks ago, I actually started writing a program to evaluate something like the question you're asking. My plan was to work out the basic architecture of the program using an Excel macro (written in Visual Basic for Applications), to make it easy to troubleshoot bugs, then eventually convert it into an executable program (for speed), with much, much larger populations and phenomes. Unfortunately, I haven't had the opportunity to develop it beyond the initial working model, which only shows mutations accruing in artificially-selected, asexually-reproducing organisms. The Excel VBA source code is below. If you have Excel, you should be able to run it by doing the following: 1. Start a workbook and rename two workseets "E" and "P" (for "environment" and "phenome"). 2. In the "E" sheet, enter the following values: 100 into cell B1; 100 into cell B2, 1 into cell B3; and 1 into cell B4. These values correspond to initial, working values for the number of "organisms", the number of "phenes" each organism has, the overall mutation rate (%), and rate of beneficial to detrimental mutations (%). 3. Create a macro and paste in the source code. 4. Go to worksheet "P" and run the macro. The macro will automatically populate the cells and run 20 generations... Others are welcome to develop the program further, provided that they make the improved program(s) and source code freely available on the Internet to everyone. (BTW, I'm not a software engineer, so criticisms of my coding would be wasted effort.)

Jerry says "Socialism emphasizes cooperation and equality of results which is certainly not natural selection..... It would be funny if what kills Darwin in schools is socialism." Not likely. Most of our big secular humanists are big believers in both NDE and Socialism. How could this be? This certainly appears paradoxical at first blush. Well, perhaps it can be reconciled and explained if you look for the invisible common thread -- control through manipulation, which requires elimination of transcendent truths and allegiances. Look at it this way, I cannot control you successfully if you already have a firm belief in a higher purpose that serves as your anchor. But if I can convince you that no such factor or power exists, than you are free to be manipulated by whatever enticement or fear grabs you and holds you. Then I go to phase two, preaching liberation to you while all the time I am covertly promoting your dependence. Oh yes, you must depend on us for your medicines, your free drug needles, your housing, and your environment, etc etc. It is all nearly free. But is it? Just ask those who got hooked on welfare. A near perfect strategy, is it not??Ekstasis

So where can a person introduce a perfectly intriguing argument for a thread that doesn't exist. I can't find a better place to put it, so I'll put it here. I have been looking for a way to illustrate what I call the signal to nose ratio problem. Consider five organisms that each contain 200 genes for which there are two alleles. Let us order the alleles, calling the slightly less fit for the current environment (possibly more fit for a slightly different environment) allele 1, and the more fit, allele 2. We can now determine the relative fitness of the organism by adding up the allele numbers. Now we throw in a new, slightly beneficial mutation, and give it allele #3. One of the organisms below has an allele 3. Do you really think that if we added reproduction, allele mixing (which doesn't even happen in non-sexual organisms) and natural selection that natural selection is sensitive enough to cause allele 3 to spread throughout the population? I kinda doubt it. Now what if every cycle we also through in two or three allele 0s at random? Would that not make natural selection's challenge even greater? What if we assumed an average of 2 alleles for each human gene. With this assumption, the one beneficial allele is lost in a jungle of 25,000 alleles (if you limit your count to coding genes.)

The theory has been proposed that Darwin's mind was pre-disposed to his theory of evolution as a result of political economics such as that developed by Thomas Robert Malthus, writing between 1798 and 1826. Here is one of Malthus' excerpts: " ...in all societies, even those that are most vicious, the tendency to a virtuous attachment is so strong that there is a constant effort towards an increase of population. This constant effort as constantly tends to subject the lower classes of the society to distress" Note the competition for resources and the survival of the fittest themes! So, while Darwinian evolution has influenced political thought, the reverse also happens. Yep, science in practice is still subject to all the foibles of the human psyche.Ekstasis

Hi Poachy, you're right. This is a very complex issue. I think it is safe to say that there are connections between the untethered free market and social Darwinism. I don't think this can be denied. Obviously the Nazi's ideas on race and 'living space' were influenced by Darwin. Marxism believes that man is shaped by his economic environment Create a 'better' society and man will become better. I think this is Lamarkian. That is a brief and simplified summary. I think 'survival of the fittest' style capitalism and Nazi ideology are closer to Darwinism than Marxism.Dembskian

poachy, Darwinism hypothesizes competition for limited resources and then survival of the fittest which is at odds with socialism. It means there are winners and losers and that is associated with capitalism. Socialism emphasizes cooperation and equality of results which is certainly not natural selection. Don't expect consistency. Both the Nazis and Communist were socialists. One rejected Darwin and one embraced him. Marx liked Darwinism because of its atheistic ideas while Stalin objected to it and forced through a different theory of evolution. Hitler's race based theories used Darwin as justification for their attempts in purifying the race. Current socialist thought doesn't like Darwin because of it says we are all not equal. So you will get nutty theories to fit in to their ideology. It would be funny if what kills Darwin in schools is socialism.jerry
