You could actually present the data from experiments. That would be a refreshing change in tactics. You know, do some actual science instead of lawyering.
I am not a scientist, how can I present data? I can only read the papers of the scientist who have presented the data in their papers.

How can you accept something that you don't understand? What is this work? Can you please point to the data that Shapiro has produced which demonstrates nonrandom mutations with respect to fitness? No more "I read his conclusions". I want to see you present the data, figures, and tables found in the results section of his papers and show us how these results point to nonrandom mutations with respect to fitness.
Shapiro presents the data, I present his findings from the data per his papers.
Using your procedure, only scientists could post on this board.
There have to be positions presented from the data outside the mere mechanical physical and chemical data.
The scientists on this board must be open to causation that flows from the data.

Wounded King writes:
So if transcriptionally active/derepressed genes are more liable to mutation then at these early stages that bias would be towards genes associated with early development which are prime candidates for being subject to strong selective pressures due to the sensitivity of early development.
Are you agreeing that these are non-random mutations that are beneficial for fitness?

Can you see that there is no decision being made, and no sentient process whatsoever, by the grass seed as to which direction it will grow in? It wouldn't be too terribly inaccurate to say that the plant "senses" the direction of gravity so that the direction of growth could be "determined". Although, that could be interpreted to be some decision making process by the plant even though there's a perfectly reasonable explanation for it:

Less well known is that, in the second half of his life, Darwin’s major scientific focus turned towards plants. He wrote several books on plants, the next-to-last of which, The Power of Movement of Plants, published together with his son Francis, opened plants to a new view. Here we amplify the final sentence of this book in which the Darwins proposed that: It is hardly an exaggeration to say that the tip of the radicle thus endowed [with sensitivity] and having the power of directing the movements of the adjoining parts, acts like the brain of one of the lower animals; the brain being seated within the anterior end of the body, receiving impressions from the sense-organs, and directing the several movements. This sentence conveys two important messages: first, that the root apex may be considered to be a ‘brain-like’ organ endowed with a sensitivity which controls its navigation through soil; second, that the root apex represents the anterior end of the plant body. In this article, we discuss both these statements.Key words: auxin, cognition, plant neurobiology, plant tropisms, roots, sensory biology, signaling Other Sections▼

Nevertheless, both animals and plants show movements of their organs; but, as mentioned, these take place at greatly different rates. Present day results,8—13 however, are increasingly coming to show that, in contrast with the classical view, plants are definitely not passive automatic organisms. On the contrary, review they possess a sensory-based cognition which leads to behavior, decisions and even displays of prototypic intelligence.4,12 Other Sections▼

I really don't base by religious ideas on biologists. I have had my religious beliefs for many years and they have continually gotten stronger as my life and experiences have unfolded.
What I am saying in this thread is that Shapiro and those in the school of communicative cell discoveries, are reinforcing my religious beliefs.
If I am wrong about these biologists, it won't change my religious beliefs.

Shapiro is talking about it being directed by natural means, and so is Wright. I think you may be getting a bit over excited by expressions like "natural engineering" which, like "natural selection", has nothing to do with teleology.
I understand what Shapiro is saying in "natural genetic engineering" but he nor any scientist is the last word on the cause or initiator of these discoveries.
In the end for this subject it all comes down to the Orgin of Life.

How so? What does it say that goes in the same direction?
This quote is from the paper "the root-brain hypothesis... cited in my message
Outlook: Complex Social Life of Plant RootsRecent advances in chemical ecology reveal the astonishing communicative complexity of higher plants as exemplified by the battery of volatile substances which they produce and sense in order to share with other organisms information about their physiological state.102—109 The next surprise is that plants recognize self from nonself; 109 and roots even secrete signaling exudates which mediate kin recognition.10,11 Finally, plants are also capable of a type of plant-specific cognition,3,110 suggesting that communicative and identityre-cognition systems are used, as they are in animal and human societies, to improve the fitness of plants and so further their evolution. Moreover, both animals and plants are non-automatic, decision-based organisms. Should Charles and Francis Darwin have witnessed these unprecedent discoveries, they would surely have been pleased by them.
The paper clearly is in line with what Shapiro is saying about cells in his papers .
The plant cells are capable of cognition and communciative systems such as those in animals and human societies that improve their fitness and further their evolution.
Thus these cells are, per Shapiro's papers also beyond the tenets of the modern synthesis, and in my opinon that suggests planning and not randon mutation and selection.
I cannot prove this at this point, but it is a valid interpretation of a planned process .

Do you agree that she is proposing that her paper does support non-random mutations for fitness?
And if so is that in conflict with the modern synthesis?

It is your opinion that I misinterpret Shapiro's findings. He said I understood them pretty well.
In a court of law I, as the attorney, present the Expert, in this case Shapiro via his papers that contain the data, and then with the evidence admitted into evidence, I interpret his testimony in my argument to the jury. That is what I am trying to do in this thread.

Barbara Wright writes:
This minireview will describe mechanisms of mutation that are not random and can accelerate the process of evolution in specific directions. The existence of such mechanisms has been predicted by mathematicians (6) who argue that, if every mutation were really random and had to be tested against the environment for selection or rejection, there would not have been enough time to evolve the extremely complex biochemical networks and regulatory mechanisms found in organisms today.
She does not mention neutral and detrimental mutations, but only those that are non-random for fitness.

You are right that the attorneys arguments are not evidence, but the attorney comments 0n and interprets the evidence, i.e. the data in this case and Shapiro's testimony and opinions, and the jury then makes a decision on the isssue.
In re the Expert. The evidence would be presented by the Expert under direct examination by Plaintiff's counsel and then cross examination by defendants's counsel
The data would be admitted by both the experts testimony and the admission of the papers into evidence.The jury, in some cases, may even take the actual papers with them to the jury consulation room where they reach their verdict.
There is no hearsay problem under that procedure.

Nowhere in that quote can you find the word "fitness". She mentions random mutations, but she does not mention how they are random. Like we have said many times, mutations are not random with respect to time and sequence, but they are random with respect to fitness. It's not as if skydivers acquire mutations that produce wings in their children.
I interpret the above part of the quote to mean the non-random mutations she discussed provided a benefical adapation of the organism to its new enviroment.

Re: Dr. Wright's conclusion
Dr. Wright writes--------------------------------------------------------------------------------
Regardless, a mechanism that limits an increase in mutation rates to genes that must mutate in order to overcome prevailing conditions of stress would surely be beneficial and therefore selected during evolution.
NoNukes writes:
Wright says that the mechanism for generating non-random mutations is beneficial. In other words, the presence of mechanisms for non-random mutations is itself a product of mutation and selection (and most likely evolution of the neo-Darwinist type). She definitely does not say that the generated mutations would be surely beneficial.
You are reading a paper describing natural processes. If something "seems to saying" otherwise, you need to dig harder to be sure. I'll admit to having understood the paragraph as you did the first time I read it.
I interpret that to mean that a mechanism is limiting the mutation rates to non-random mutations to certain genes under stress would be beneficial to those genes and selected for evolution.
That is not a process put forth by the Modern Synthesis and goes beyond the modern synthesis.
Here is an interesting quote from Dr. Wrights paper page 4.
Dr. Wright writes:
It is noteworthy that the experiments described above on the effects of artificially induced transcription on mutation rates in growing cells are all examples of specifically directed mutations.
However, none of the researchers come to that conclusion or challenge the assumptions and implications inherent in the experiments of Luria and Delbruck (63), which reinforce neo-Darwinism.
This situation may be due to the dominance of current dogma and to the assumption that mechanisms operative during growth cannot also be critical during evolution under conditions of environmental stress.
In fact, the limited evidence now available suggests that only growing cells, or cells in transition between growth and stationary phase, have the metabolic potential required for specific, transcription-induced mutations in response to environmental challenge....
She seems to be challenging the experiments of Luria and Delbruck in re random mutations that Taq previously cited.
She is also saying that dominance of current is perhaps is having a negtative effect on scientists who may put forth critical or different views than the current dogma holds.
It surely seems some scientists are in fact challenging the modern synthesis.

already read it. It is wrong. You don't get to present expert testimony even as a written affidavit. Even worse, you don't get to present your interpretation of the expert testimony as evidence. Expert witnesses have to present the data that supports their conclusion, and they have to be available for cross. That's how it works. That is how it worked in the famous Dover ID trial where ID advocates were not allowed to submit written affidavits. They had to be available for cross. You should know that.
Taq, your on my territory now. You did not fully read my post or misunderstood it.

I am clearly saying that the expert is on the witness stand under both direct and cross examination. That his testimony and ID'ed documents would also be admitted into evidence.
The Dover trial was a bench trial, i.e. before a judge with no jury. However both Plantiff's and Defendant's attorneys made closing arguments to the judge as to what they believed the evidence showed.
