Give me the statements you want cites to and I will give you the cites.
Are you suggesting any of those statements are changed from what Shapiro said? Do you think I am making them up?

Let's leave aside RM & NS for a moment.
In the least he is discussing a built in information system in the cell. Yes. And?
A major problem, often cited by religious and other critics of orthodox evolutionary theory, is how to explain the appearance of complex genomic systems encoding sophisticated multicomponent adaptive features.99, 100 The possibility that computational control of natural genetic engineering functions can provide an answer to the problems of Irreducible Complexity and Intelligent Design deserves to be explored fully. Contrary to the claims of some Creationists,99 these issues are not scientifically intractable. They require an application of lessons from the fields of artificial intellligence, self-adapting complex systems, and molecular cell biology.100, 101 We already have some clues about how to proceed in addressing complex novelties in evolution. As McClintock first demonstrated, insertions of MGEs at distinct genetic loci bring them under coordinate control.8, 64, 66 Thus, we know in principle how multi-locus genomic systems can originate. Once such systems exist, we know that the transcriptional regulatory apparatus is capable of specifically accessing the component loci in response to biologically meaningful signals. The Significance of Cellular Activity in Genome Reorganization = Formatting and reformatting the genome for computation and exp Shapiro sees an evolutionary explanation for these systems.

This butchered mess, shadow.
The cell is a multilevel information processing entity and the genome is only part of the entire interactive complex. Mobile DNA movements rather than replication errors serve as the primary engines of protein evolution. Horizontal DNA transfer between species and between the 3 high kingdoms of living cells may be a major driver of evolutionary novelty. Genomic data documents the fundamental importance of horizontal transfer in the evolution of bacterial and archaeal genomes. There is growing evidence for intercellular and interkingdom horizontal transfer events in the evolution of eukaryotic genomes. Genome sequencing introduced a major process of rapid and multicharacter change into the established evolutionary record which has been largely ignored by the neo-Darwinian followers. Whole genome doublings is another evolutionary process out side the Darwinian perspective that occurs suddenly, within a single generation, and simultaneously affects multiple phenotypic character. Synthetic speciation takes place rapidly after hybridization rather than slowly following repeated selections, as predicted by conventional theory. Hybridization in the Darwin’s finches in the Galapagos Islands, long a paradigm of gradualist evolution, leads to abrupt, unpredictable changes in beak shape. The virtual infinite dimensions of possible genome configurations has too low a probability of success via the Darwinian gradualism which is too slow and indeterminate a process to account for natural adaptations even allowing for long periods of random mutation and selection. Evolutionary change by natural genetic engineering employs a combinatorial search process based upon DNA modules that already possess functionality. Hereditary variation arises from the non-random action of built-in biochemical systems that mobilize DNA and carry out natural genetic engineering. And this.
That Random mutation and selection have a low probability of success and that the molecular findings above are the major mechanisms for the evolutionary process. That gradualism is not a major factor in evolutionary change, but rather the novel adaptations that require changes at multiple locations in the genome can arise within a single generation and can produce progeny expressing all the changes at once. As to natural selection, I beleve he finds it not as important as natural genetic engineering selection. Most of those are unattributed word for word swipes from Shapiro. Plagiarism: submitting material that in part or whole is not entirely one's own work without attributing those same portions to their correct source.

Both the RM & the NS questions have been answered.
You won't listen to me and you won't listen to Taq.So let's ask Shapiro. Yes?

Have you read Dr. Guenther Wizanty? Schaack, Gilbert, and Feschotte? Adam S. Wilkins? I won't bother you with quotes, because I know How much they bother you. Edited by shadow71, : spelling

At this point I would just be repeating myself and reposting Shapiro quotes.
But you'd take Dr. Shapiro's word on what he does or does not think about RM & NS, wouldn't you? jsha@midway.uchicago.edu

Let's agree on some wording.
I proposed this earlier: Let's you and I try to put together your take on Shapiro's view. 1. All mutation is nonrandom.2. Natural selection works so poorly that essentially it doesn't work at all. 3. All evolution occurs due to cells rearranging their own genomes (aka NGE). 4. Cells are intelligent.

Pick one or two and tell us the specific changes they will cause to the genes of individuals. You won't be able to do this because when Shapiro says non-random he doesn't mean guided and certainly not deterministic. OK For Extracyto-plasmic stress the response will be an F plasmid Transfer (Lau-Wong, I.C. et al. 2007. Activationof the Cpx regulon destabilizes the F plasmid transfer activator, TraJ, via the HslVU protease in Escherichia coli. Mol. Microbiol. 67: 516—527.) For Plant phenolics the response will be T-DNA transfer toplant cell in a A. tumefaciens bacteria (Gelvin, S.B. 2006. Agrobacteriumvirulence gene induction. Methods Mol. Biol. 343: 77—84.) In E.Coli aerobic starvation will cause a Mu prophage activation. Should I go on? Two choices for the explanation of life in the world, Percy, random or non-random. You let me know when you can come up with a third choice.

Hi Bolder-dash,
You misunderstood or misread the question. The question asked about the specific genetic change. Your position is that the term "nonrandom" refers to guided or directed changes in the genome toward a specific goal resulting in improved competitive success in the current environment. But when asked for examples all you provided was:
Bolder-dash writes: For Extracyto-plasmic stress the response will be an F plasmid Transfer... For Plant phenolics the response will be T-DNA transfer to plant cell in a A. tumefaciens bacteria ... In E.Coli aerobic starvation will cause a Mu prophage activation. None of these processes result in genomic changes directed toward any specific goal of improvement. The result is random with respect to reproductive success within the environment. Actual improvement to the genome will be through selection of these random changes across a population of organisms experiencing the same environmental stresses. Care to try again? Or would you like to finally acknowledge that "nonrandom" in the way that Shapiro is using the term does not mean guided toward any specific goal? What Shapiro actual means by nonrandom is that the when, where and type of mutations is to some degree under the control of molecular processes within the cell. What is not under cellular control is what the mutation will do and whether the mutation is beneficial or not. --Percy

Two choices for the explanation of life in the world, Percy, random or non-random. No, apparently there is a third option. You could gibber out dishonest equivocations on the word "random", and we could laugh at you. You silly little man.

Let's ask him if he believes random mutation and natural selection are the major aspects of evolution ok? Don't you want to ask Shapiro questions that would actually cast light on whether you're misunderstanding him or not? I think you need to ask him whether non-random means guided. In answer to a question posed during a "chat" at William Dembski's ISCID (International Society for Complexity, Information and Design) Shapiro answered thusly (this is taken from James Shapiro Chat, and links like this are the kind of information Molbiogirl has requested that you supply when you're cut-n-pasting, and I think everyone else here feels the same way, in addition to making unambiguous which words are your own and which are not):
James Shapiro writes: Non-random means that they operate under certain conditions (e.g. after genome damage or viral infection) and that these systems make characteristic kinds of changes. When a retrovirus-like element inserts in a new genomic location, it carries with it a defined set of regulatory signals that can affect the reading of nearby DNA sequences in very particular ways. This is an example of non-randomness. In addition, some changes (such as those in the immune system) can be targeted to specific locations by the presence of particular signals in the DNA or by activation of transcription. These phenomena show us that cells are capable of altering their genomes in non-random but not rigidly specified or pre-determined ways. In other words, the mutations are random with respect to their effect or impact on fitness, but they are nonrandom with respect to the type of mutation and where in the genome they occur. Since they are random with respect to their effect they cannot be considered guided toward any particular goal. They are nonrandom in the sense that the types and locations of the mutations are more likely to have a relevant effect, but that effect would still be random with respect to fitness. --Percy

Percy, there is nothing random at all about the engineering that the cells are doing to counter specific environmental stresses.
I am not sure why you feel the need to figure out Shapiro's use of the word random? I don't know how Shapiro's uses the word, nor do I particularly care. I will do you the service of using another word, say "random~shap" to refer to a version of random that has something to do with his take on the word if I ever use it. In the meantime, when I say random, you can safely assume that I just mean the word random, and not "random~shap". Now, the processes which control these genetic changes are NOT random! Question: Is it painful for you to watch the needle slowly drifting towards a guided world? Clearly it is for Dr. A. He is clenching his butt cheeks so hard that he is seeing everyone as little men. You better watch out for him, I am afraid he will have an anal anyeurism soon.

Bolder-dash writes: Percy, there is nothing random at all about the engineering that the cells are doing to counter specific environmental stresses. You think the cells are doing engineering? What actual engineering do you see them doing? Engineering is just a colorful way of referring to the microbiological processes within the cell. Regarding your claim that there is "nothing random" going on, the result of these processes is random with regard to fitness, so obviously there *is* something random going on. As has been explained to you, evolution is a combination of both random and nonrandom processes. Mutations are random with regard to fitness. Selection is nonrandom with regard to fitness. DNA replication during cell division is primarily nonrandom with regard to the sequences produced in the DNA copies. The mutational errors that occur during cell replication are random with regard to fitness, and they're also fairly random with regard to location and type. This means that bold claims like this are wrong:
Now, the processes which control these genetic changes are NOT random! Some processes, like selection and DNA replication, are not random. Some processes, like mutation type and their effect on fitness, *are* random. These random components are why you're unable to describe any specific genetic changes improving fitness that would be caused by your list of processes. They're why evolution isn't guided.
Question: Is it painful for you to watch the needle slowly drifting towards a guided world? Clearly it is for Dr. A. He is clenching his butt cheeks so hard that he is seeing everyone as little men. You better watch out for him, I am afraid he will have an anal anyeurism soon. It's stuff like this that causes moderators to ignore your complaints about ill treatment. You might try perusing rule 10 of the Forum Guidelines and leave the personal stuff out of your posts. --Percy
