I was just thinking about mentioning that. They say you can take all the
phones, computers, tablets, etc. in the world today, put them all together
and it would all equal the power of one human brain.
Apparently nature just came about developing something like that
by mere time and chance. And that is just your brain.
The import of my research continues to be misunderstood and mischaracterized, often using straw-man arguments and continued assumptions of what natural selection (NS) is capable of doing. Gould did not deny that NS occurs and neither do I—he pointed out that it must occur at the organismal level. Individual areas of DNA or RNA simply “do not have [access] to NS”, was his point [or really, that NS does not have access to them within individual cells]:
““‘…no matter how much power [Richard] Dawkins wishes to assign to genes, there is one thing that he cannot give them – direct visibility to natural selection’. Rather, the unit of selection is the phenotype, not the genotype, because it is phenotypes which interact with the environment at the natural-selection interface.”
Now, returning to the most salient point regarding expected genomes and proteomes, if naturalistic processes were in fact responsible for their origins:
The genetic code allows making some theoretical predictions about average protein size and frequency distribution [1,2,3]. Since stop codons can appear stochastically after any start codon, then larger proteins should always be less frequent than smaller proteins. The most frequent protein sizes should be 1 aa in length [4].[5]
But this is not at all consistent with empirical data. Furthermore, calculations can be made of the expected amount of junk DNA within cells, IF naturalistic processes were the only ones involved in their genesis.
Where is the mechanism within cells, to clean up the 99.9999% of junk that would naturally accompany the random search for necessarily lengthy genes? Do the math on ONE gene of 2500 codons in length. How much junk would occur under random naturalistic chemical processes? What amount of molecular resources do you think were really present in the hypothetical primordial ooz? It is irresponsible to assume unlimited resources.

Are you saying natural selection built something that humans
can't even begin to do? From the bottom up?

Yes, I read the entire article. What I also did was to separate in my mind empirical science from pure speculation. Anyone can tell stories about wishful events. The key is to test the actual feasibility of those things, using the evidence you have.
Isn't it interesting that this article offers glib reasoning as to why very long proteins are "usually not seen" (referencing the effects of stop codons) and yet it utterly fails to apply that math to known genes in virtually every type of cell which are very long. Instead of doing the math, as I have done in my research, they simply add more mythology to the equation.
They simply assume that function dictates selection--without providing any step-by-step example of how that would occur--how would it clean up the incredible volumes of mess that you would see if you only followed through with the challenge I posted numerous times--sit down and calculate the total molecules which would be used up, on overage, for EACH trial at producing a single ORF of 500 codons (a very "average" size BTW).
And notice that in the article, none of their models was even 50% accurate in explaining the empirical data. What kind of a grade would you give it?
Um, so? Both Gould and Dawkins were in complete agreement that deleterious mutations are eliminated by natural selection. Their disagreement has nothing to do with your denial of the effectiveness of natural selection at removing new, harmful mutations.The import of my research continues to be misunderstood and mischaracterized, often using straw-man arguments and continued assumptions of what natural selection (NS) is capable of doing. Gould did not deny that NS occurs and neither do Ihe pointed out that it must occur at the organismal level.

You didn't do the math. You calculated part of the easy bit -- how quickly will mutations break down ORFs (although you don't seem to know how often such mutations actually occur) -- but have done no calculations about the creation of ORFs, by any mechanism.Split Rock posted: "...We assume that the frequent occurrence proteins of size 150-250 aa is due to protein folding stability..."

Produced how? You can't calculate anything until you specify the model, and you've insisted that only one model -- creation from random sequence -- be considered. Why?They simply assume that function dictates selection--without providing any step-by-step example of how that would occur--how would it clean up the incredible volumes of mess that you would see if you only followed through with the challenge I posted numerous times--sit down and calculate the total molecules which would be used up, on overage, for EACH trial at producing a single ORF of 500 codons (a very "average" size BTW).
Compared to the 0% of the empirical data that any creationist model explains? I'd give it quite a good grade. When has a creationist offered a calculation of the expected distribution of gene lengths in their model?And notice that in the article, none of their models was even 50% accurate in explaining the empirical data. What kind of a grade would you give it?

We never assume that -- biologists have done extensive research on the limitations of mutation.Evolutionists stack the deck in their favor by several common tactics:
1. Assume unlimited powers of mutations
Natural selection has many well-known limitations. You should know these things if you're going to attack the science.2. Assume unlimited powers of natural selection
I have no idea where you got this notion. It resembles nothing in evolutionary biology.3. Assume unlimited supplies of resources were available in the past
The amounts of time are known very well, thanks to geologists and physicists and paleontologists.4. Assume virtually unlimited amounts of time
Adjusting theories to evidence is a good thing if you want to model reality. Of course, you could choose instead the creationist path: decide in advance what the theory is, ignore all evidence to the contrary, and spend your energies attacking scientists rather than trying to understand the natural world.5. When evidence surfaces that refutes your theory or hypothesis, come up with ad hoc retrospective alterations to it and pretend that none of the criticisms matter.
How is it a big if? If a mutation causes one wombat, say, to have a premature stop codon in a gene, it's going to be worse off than all of the other wombats, right?"We assume that the frequent occurrence proteins of size 150-250 aa is due to protein folding stability (for example TIM barrels) that generates a selective pressures avoiding stop codons within exons or genes."
Did you catch the word "assume" beginning the sentence? Natural selection cannot prevent stop codons from occurring when mutations or random generation of sequences makes the sequences with then in the reading frames. The only think NS can do is bury the entire organism or cell, IF a "fitter" organism or cell is there to compete for sustenance or reproduction. That's a really big if,
What junk DNA question?and it doesn't address the junk DNA question.
No, I didn't catch it. Sounds like a reasonable statement. Were you under the impression that scientists knew everything already?Also, did you catch this quote from the article? -- "The evolutionary forces that have shaped protein number and size distributions in modern organisms are unknown."
Okay, let's get started. In a designed organism, what distribution of gene lengths should we find -- before evolution has any effect, say. Should we find any duplicated genes? Will genes come in families? Will there be genes that combine parts of other genes? Will there be functional genes that look exactly like retroposed transcripts of other genes?As I reflected back on this article, it seemed to me that the authors, if they were completely candid and honest, were essentially saying; "we have no earthly idea why the observed distributions of gene and protein lengths do not conform to any modeling of evolutionary origins". I would suggest that by going a bit further and doing the appropriate math, you should be looking at a model of origins that begins with design/creation and then adds mutation and natural selection over time.
Well, you also have to include the random mutations and the ongoing reproduction and competition, but, including all that, yes.
You see, advantages accumulate. One comes along, gets established, and then another gets added to it that enhances it or complements it . . . that gets established, another comes along gets added, enhances or complements it. . . .etc etc.
Clearly, such a process would take a looooong time but, given long enough time, there is no limit to the number of enhancements that can be added.
And the end results would be . . . wonderful!

Paul said: "Sounds like you are explaining why so much DNA is junk DNA."
Look at the results of the ENCODE project. There is far less junk than previously thought and we are just beginning to understand a small portion of the epigenetic regions.
If you will do the simple desktop "experiments" I have suggested and follow them through, you will notice that even the amount of junk touted by some evolutionists for certain cells is multiple orders of magnitude less than what would occur under random or naturalistic generation processes. I challenge you to do the math.
