You have so many false underlying premises and contradictions here.....
I have one word which trumps your two words, mathematics.God forbid that I bore an evolutionarian with facts.What you are observing are microevolutionary processes and extrapolating these processes to macroevolution. Darwin misinterpreted the variations of bird beaks as mutation and selection when what he was observing was recombination and selection. Gould made the same error when he proposed his concept of punctuated equilibrium which is applicable to recombination and natural selection but not to mutation and selection. Evolutionarians have extrapolated the rapid changes that are possible with recombination and natural selection to mutation and natural selection. Dr Schneider’s computer model reveals the problems with this extrapolation.So let’s see you apply some mathematics to your genetic science and do the bookkeeping required to account for your theory. Dr Schneider tried this with random point mutations and natural selection and this mechanism does not balance the books. So choose your mechanism, formulate the mathematics and balance your books. In case you haven’t noticed, there is no selection mechanism that would evolve a gene de novo.Why don’t you describe the selection process that would give rise to the HIV virus de novo?Why don’t you give us the benefit of your vast knowledge and describe the selection process that would give rise to a gene de novo?Anybody on these links describe the selection process that evolves a gene de novo?You are missing the point to this discussion. The argument I am raising here is that Dr Schneider’s ev model of random point mutations and natural selection shows that this mechanism is profoundly slow at accumulating genetic information when realistic genome lengths and mutation rates are used in the model. The rate of information acquisition is far to slow to explain macroevolution by this mechanism. Dr Schneider is the head of computational molecular biology at the National Cancer Institute. His model has been peer reviewed and published in Nucleic Acids Research. If you believe that gene transfer mechanisms, horizontal gene transfer, molecular genetics, genomes in flux or gene transfers to plants by diverse species of bacteria will correct the mathematical deficiency that Dr Schneider’s model reveals in your theory, formulate the mathematics and correct your theory. Otherwise, your theory started without a mathematical basis and remains that way.What I argue is that random point mutations and natural selection is the cornerstone to your theory. Without this mechanism, all the other mechanisms you describe will not be able to fill the gap left when this mechanism is removed from your theory. Not only does Dr Schneider’s computer model remove random point mutations and natural selection as a viable explanation for macroevolution, it reveals another fatal flaw in your theory, that is a lack of a plausible selection mechanism for the evolution of a gene de novo.This is evidence for microevolution or genetic modifications by intelligent scientists. Since evolutionarians like to say that macroevolution is simply a series of microevolutionary steps, I have challenged this view that macroevolution is the de novo evolution of a gene. There is no selection process that would do such a thing.Since joobz won’t tell us how ribose formed in the primordial soup, perhaps you would tell us?
Micro evolution only nonsense is one of the weakest arguments of the evolution deniers' debate. It was a last ditch effort. "Oh yeah, well prove this then." "Umm, OK, then prove this." and on and on. Micro evolution only arguments arose when it was clear evolution in real time was indeed observable.
I told you, the genomes trace a map from the earliest organisms (and we know they are early because their genomes are the smallest) to all the other genomes on the tree. A pattern has emerged which shows how Behe's infamous flagellum argument is wrong. The pattern shows exactly how one goes from one species to the next. Just where are your invisible divisions in this tree of Life diagram?
There's nothing in any mathematical calculation that contradicts what is clearly visible in the DNA and RNA of every living thing on the planet. You are wrong, and outnumbered by the vast majority of scientists and mathematicians. For whatever reason, (I assume it to be you are invested in the outcome of denying evolution because it challenges your existing beliefs), you continue to only look at selective evidence.
No evolution mechanism for de novo gene in your knowledge base, the math fails in your limited selection of evidence, (I'm not even sure I agree with that since there is a lot of rebuttal you are ignoring in the talk origins and Panda's thumb web sites). You keep going on with your selected random point mutations ignoring all the observed mechanisms for gene mixing, gene transfer, segmentation of function which allows a single mutation to produce 6 fully formed and functioning digits instead of 5, and a rabbit embryo 'eye growth initiating gene' to be exchanged with the corresponding gene of a a fruit fly larva resulting in a perfectly normal fruit fly compound eye, and lastly the robustness of function which included the discovery the reason Behe's flagellum precursor was hard to find was the precursor wasn't similar. The flagellum arose from some completely different gene function.
Your single point mutation math was all for naught. "The rate of information acquisition is far to slow to explain macroevolution by this mechanism," because it isn't anything close to the complete process by which evolution occurs. "...formulate the mathematics and correct your theory." No need to, you haven't accounted in your model, or should I say Schneider's model, for the mechanisms which result in genetic change I have already documented. You have a flawed model which the folks at or similar to the folks at the Discovery Institute and AIG have selected (punny
Evolution is observable.
- If you can tell me where species divisions occur in organisms' genetics,
- if you can sufficiently explain why genetic material is precluded from being added or subtracted from DNA molecules which is required if your hypothesis were even remotely correct that genetic material can only be exchanged,
- and, if you can explain your hypothesis why if genetic material can be exchanged that precludes exchanging enough material to result in a new species (Hint: for such an hypothesis, you would need to show how genomes differ from macro-species to macro-species.)
Going on that last point, it comes back to my two words, genetic science. If you had a better understanding of genetic science, you would already know that
- the difference in species is not related to the number of genes,
- that diverse species share an incredible amount of genetic material
- and, that many many examples of transitional species as well as transitional organs like eyes exist in real time.
The HIV virus didn't arise de novo, if you had done your homework you'd know the origin has been traced back to a place where the SIV and the HIV viruses diverged.
"Since evolutionarians like to say that macroevolution is simply a series of microevolutionary steps, I have challenged this view that macroevolution is the de novo evolution of a gene." No you haven't. You have selected (punny !) a single process for genetic change and claimed it was the main if not the only process. That is a patently false underlying premise in your version of reality.
You have a poor understanding of what genomes actually consist of. You are using the typical concept of evolution deniers, that of the results of the genome. A dog has features that differ from a cat and they cannot mate. But in the blueprints, the two have surprisingly similar genomes. Not only that, but you can map the genetic changes to determine how long ago the two species split from a common ancestor.
Genetic scientists are so far past those basics. Where the research is now being concentrated is in identifying what all the genes do, identifying how the genetic code results in the construction of proteins, how those proteins fold to make structures, how the codes are turned on and off, how much play there is in the system which means you can have a lot of 'single point mutations' without interfering with the function of the gene, and how to repair genetic errors by inserting new genes via viruses.
Do you really think we could do all that and still not understand the most basic means organisms evolve? But you in your mathematical wisdom see the folly in a science you know so little about?
Let me give you one more thing to think about. Do you think it is possible you've been duped? Have you read anything about the Discovery Institute and the wedge strategy? Are you aware this Christian think tank is not full of scientists like Behe (though they do rely heavily on any scientist ally they can find)? Instead, the DI is staffed by marketers and dare I say it, propaganda experts.
They would have you believe evolution scientists are all atheist activists. But there are many many theist evolution scientists. The Pope has acquiesced. The DI would have you accept Intelligent Design but the Bible says Creation. So there is an argument among theists. Theists argue over the literal interpretation of the age of the Earth. Some have gone with the science, some have not.
What is my point? Science is the stability factor here. Theists pick and choose which interpretations of the Bible they are going to buy. Scientists follow the evidence. Evolution theory has nothing to do with the Bible. No scientist cares if Bible myths are close or far from observed reality unless maybe they are investigating the myth. Science has no reason to ignore supporting evidence if it is there. If there were true evidence making the theory of evolution in doubt, why wouldn't you see an army of theist scientists supporting serious doubt in evolution theory?
The DI would have you believe there is anti-Bible bias in science. Why wouldn't the army of theist scientists be protesting the covering up of such evidence? And scientists buck existing consensuses in droves when the evidence bucks the consensus. The world is much too diverse, with theist and atheist, American, European, Asian, and Oceanic, male and female, young and old, gay and straight scientists out there. For 5 decades this diverse group of scientists has been researching every aspect of the theory of evolution.
If the theory were flawed, evidence would be mounting against the theory. Instead, all the evidence has led to one conclusion. And genetic science provided massive, overwhelming evidence filling the gaps in the theory of evolution. It could not have stood up to this scrutiny were it not correct. You wouldn't need the DI and a straw argument which selected (punny
As to, "There is no selection process that would do such a thing.Since joobz won’t tell us how ribose formed in the primordial soup, perhaps you would tell us?", is your premise that because all the details of abiogenesis remain to be discovered, the whole theory of evolution fails? Why is something undiscovered in any way, evidence it will not or cannot be discovered?
