Oh but those paintings and sculptures are conveying a message, it is communication. Didn't you take Art History? Or was that someone else?
What is the artist telling us? Visual path, focal point, balance, harmony and asymmetry all guide you into interpreting what you see. Film is 72 frames per second of still images, but through persistence of vision, you believe that what you are seeing is moving.
the painting itself doesnt determine what it means to us. you assign meaning and thats what makes it subjective rather than a reliable means of communication such as language which has a extrapersonal meaning that can be referred to and applied as needed. not sure how any of this concerns evolution.
The best and most beautiful things can't be seen or even touched , they can only be felt with the heart.
Once I knew only darkness and stillness... my life was without past or future... but a little word from the fingers of another fell into my hand that clutched at emptiness, and my heart leaped to the rapture of living.
How did she feel something greater than her immediate experience?
It's never only what you just see or touch or hear, it is what that touch does within you, that your heart can know something beyond just you. How can one expect another to see what they see, if they don't know the immediate experience of the other?
Let Helen Keller feel the cold marble and what would she conclude from it? Let her feel the entire statue then she might have another conclusion, but it didn't arise in her seeing it. She could not see the sky was blue, she had to take it on faith that you were telling her the truth.

A central tenet in evolutionary theory is that mutations occur randomly with respect to their value to an organism; selection then governs whether they are fixed in a population. This principle has been challenged by long-standing theoretical models predicting that selection could modulate the rate of mutation itself1, 2. However, our understanding of how the mutation rate varies between different sites within a genome has been hindered by technical difficulties in measuring it

Importantly, the variation is not random: we detect a lower rate in highly expressed genes and in those undergoing stronger purifying selection

Are you seriously suggesting that those biologists, palaeontologists and other scientists who have studied evolution are, somehow, taking things for granted by not looking at their own research?

what does this have to do with evolution?
Everything.
And since the thread I created, I can postulate whatever I choose.
Tell, what doesn't it have to do with evolution? It's not evolution, it is how people interpret what they see. Hand a blind person a bone you dug up out of the ground, they have to take your word and have faith it is a bone.
So, along comes someone who says "Ah, that is a fossilized leg bone of Lepus curpaeums, that evolved from a common ancestor of you and I".
See, now they have to take your word and faith that is what you are telling them to be true. Can they observe what you did? What criteria do they employ to know you are telling the truth?
It relates to my first question, perhaps I should have phrased it better, but let's revisit.
Q: Are ALL mutations random?
A: No.
Q: Are some mutations random?
A: Yes.
Q: For those non-random mutations, what are they?
A: Refer to scholarly journals.
Well, you could really only say that evidence suggests random mutations, because evidence also suggests non-random mutations. Therefore, the statement "mutations are random" means that you have to now supply evidence for random mutations, because it isn't absolute truth.
Here, if you want to pay for a scholarly journal, you can read this Evidence suggesting non-random mutations
And here Trisomy 7-harbouring non-random duplication of the mutant MET allele in hereditary papillary renal carcinomas
And here Evidence of non-random mutation rates suggests an evolutionary risk management strategy
I think it would be suggested at this time to revisit the idea that mutations are random, which was assumed in the first place. Evidence suggests otherwise.

I don't make these things up, I just find them. So how to reconcile new evidence with previous held dogma? To say there is no dogma, no orthodoxy, no faith, no belief, no creed, no article of faith within evolutionary science, is simply wrong. It had become a tenet as much as Dawkin's books.
Importantly, the variation is not random: we detect a lower rate in highly expressed genes and in those undergoing stronger purifying selection
You have to buy the full text if you want to see the experiments performed. But can we go back to the first question I posed, are mutations random? No, they are not.
So now we have to move forward to understand what these new findings will lead to.

in both cases there is a very significant departure from randomness which is primarily a reflection of a high incidence of mutations in which a guanine is replaced by an adenine in the codon for the amino acid which is changed.
However, the relationship between trisomy 7 and MET Germaine mutations is not clear.
Our observations suggest that the mutation rate has been evolutionary optimized to reduce the risk of deleterious mutations. Current knowledge of factors IMF.uencing the mutation rate- including transcription-coupled repair and context dependent mutagenesis do not explain these observations indicating additional mechanisms must be involved.

If I have demonstrated that mutations are not random, where do we go from here?
I don't think I have ever said that I don't think all facets of evolution are wrong. But I have demonstrated that this one particular thing had no evidence because new evidence has shown that my point was valid.
I don't think you can say that it is complete, young scientists are working very hard now to find the multiverses and Russel's Teapot. Let's never say it is complete, what if everyone said it was complete in Michael Farraday's day?
The original pcaG1102 deletion appears to have been guided by pairing between slipped DNA strands from nearby repeated sequences in wild-type pcaG. Placement of an in-phase termination codon between the repeated sequences in pcaG prevents growth with quinate and permits selection of sequence-guided deletions that excise the codon and permit quinate to be used as a growth substrate at room temperature.
Natural transformation facilitated introduction of 68 different variants of the wild-type repeat structure within pcaG into the A. baylyi chromosome, and the frequency of deletion between the repetitions was determined with a novel method, precision plating.
After inoculation, thousands of nonmutant colonies growing nonselectively on succinate appeared, reaching their full but tiny size by 2 days. At this time, slightly larger colonies were observed. By 3 days, the larger colonies on the precision plates became more evident and a distinctive brown tint indicated metabolism of quinate into protocatechuate. At 4 days, the tint became stronger and the mutant colonies were clearly evident. At 5 days, they were all easily distinguishable from the nonmutant colonies in the background. No new mutant colonies appeared after 4 days
Fig. 4, the relationship is not linear, and curves to fit the data could be exponential or polynomial. In light of variations attributable to sequence variation, it would be unwise to place a mechanistic interpretation on the curves. Second, deletion between repetitions of constant length falls off sharply as the distance between them increases (Fig. 5).

I don't know what to tell you about that. This is what I do know: I have never met a divine intelligence. I have never heard of a repeatable experiment eliciting consistent verifiable influences from a divine intelligence. I have no reason to believe in such an entity except as an easy answer to hard questions. I have no intention of shortchanging myself or anyone else with BS answers that are designed to stonewall rather than inform. And I appreciate your efforts to inform the forum. Your right, you have presented a good amount of evidencr and I have no immediate defense or argument to refute it. I will continue to be skeptical until concrete answers are provided one way or another.

Epigenetic changes, one of regulatory mechanisms, can modify gene activity or gene expression without altering the genomic structure,
Since the 1970s, researchers had known that the tightly wound spools of DNA inside each cell’s nucleus require something extra to tell them exactly which genes to transcribe, whether for a heart cell, a liver cell or a brain cell.
Like silt deposited on the cogs of a finely tuned machine after the seawater of a tsunami recedes, our experiences, and those of our forebears, are never gone, even if they have been forgotten. They become a part of us, a molecular residue holding fast to our genetic scaffolding. The DNA remains the same, but psychological and behavioral tendencies are inherited.
The mechanisms of behavioral epigenetics underlie not only deficits and weaknesses but strengths and resiliencies, too. And for those unlucky enough to descend from miserable or withholding grandparents, emerging drug treatments could reset not just mood, but the epigenetic changes themselves. Like grandmother’s vintage dress, you could wear it or have it altered. The genome has long been known as the blueprint of life, but the epigenome is life’s Etch A Sketch: Shake it hard enough, and you can wipe clean the family curse.
Again, like I said, all open to interpretation according to the filters you choose to use.
