Author | Topic: Information's role in evolution.Should we put it more in the picture? | |||||||||||||||||||||||||||

Is it logical to exclude this so rich and widespread function from the process of evolution ? Quite the opposite. The question is how do you define information as it relates to evolution, how do you measure it, and how do you model it. It is not a matter of excluding the idea of information. Rather, it is a question of how one models information in the process of evolution. The problem I think you are having is our disagreement with creationists as to how information is measured in these systems. For example, no creationist has been able to measure complex specified complexity (CSI) in any meaningful manner. I can find the thread later if you are interested, but there was a discussion at Uncommon Descent not too long ago where someone asked the creationists how they would calculate CSI for some very simple evolutionary examples. No one was able to do it, nor could they figure out how it could be done. On the flip side, one can derive information from genomic sequences by applying the theory of evolution. A perfect example of this is the SIFTER algorithm. SIFTER applies the theory of evolution to predict protein function, the functional information of a given sequence. From the paper:
quote: The result is an algorithm that can predict protein function with 96% accuracy, even with very little phylogenetic information to work from. So how do creationists apply ID theory to predict protein function?

It seems we agree. somehow. My Neuro-genic theory of evolution (http://www.sleepgadgetabs) tries exactly how to model information in the process of evolution.
Your link appears to be broken. Nonetheless, could you explain here how your theory can be used to analyze sequence data? Could you compare two homologous sequences from two species and show us how your theory can be used to measure the information in each sequence caused by neurogenic interactions?

We might have to go to bacteria to see the basic interactions between cell-environment, where engineering systems are , i think, the precursories of neural tissue.
Then please do. Please cite mechanisms by which specific stimuli result in specific mutations, and only those mutations. From everything I have read, mutations that occur in bacteria are random with respect to fitness. For example, mutations which confer antibiotic and phage resistance occur in the absence of either antibiotics or phage. This is the findings made by Luria and Delbruck as well as the Lederbergs (google "fluctuation experiment mutations" and "plate replica experiment" for more info). It's not as if bacteria sense antibiotics in the environment and then make specific mutations in specific genes to counteract the bactericidal activity of antibiotics. Mutations occur throughout the genome, most of which do not confer resistance to antibiotics.

You can call it an idea. But remember it is part of the comprehensive theory of Neuro-genic evolution. So how does your theory explain detrimental mutations, such as those that cause horrifically painful diseases in young children that then lead to their early death?
Information role on evolution and its mechanisms is already established by innumerable works on epigenetics and those by Shapiro, B. Wright. Dobshansky , Weismann, father of Ms theory and Darwin himself had aknowledged its significance.So sadly enough your critic is adressed to them and many others as well, not exactly to me. Epigenetics does not change the genomic sequence, and the mutations that Shapiro et al. speak of are random with respect to fitness. If you think I am wrong, then please cite a paper that demonstrates that mutations are not random with respect to fitness.

Empathy is atype of information. But it is not a type of genomic information, which is what we are talking about.
The antilope may dy, but the watchinf other members of family or tribe.
How does that observation change the genomic sequence in sperm and ova?

Indeed the genomic sequence in vertical line does not change. They do change from generation to generation. They change through mutations, but not through epigenetics. Also, HGT is mutation. It is the insertion of foreign DNA into the host genome. These events, just like other mutations, can be beneficial, neutral, or detrimental. The insertion of retroviruses into the human genome are a perfect example. By last count, we have nearly 200,000 of these insertions (most being solo LTR's). Some of them do have beneficial function, but the vast majority are acquiring mutations at a rate consistent with neutral drift (i.e. they are neutral).
I can accept that mutations for fitness are random. But there are various other previous to mutations mechanisms that are directcted by the information input, so the whole procedure becomes clearly 'a function driven evolution.'
Only heritable information can drive evolution. That is why random mutations with respect to fitness are important to the process of evolution and why your ramblings are not. Also, the directed nature of protein-protein interactions are a product of their DNA sequence. Change the DNA sequence and you can change how information is handled in the cell. Therefore, the only way to change how a cell processes information is by changing the DNA sequence. This is why random mutations are important to the process of evolution, because they are inheritable.

Epigenetics can in some cases producee permanent and inhertable changes. No, it can't. Epigenetics does not change the DNA sequence. The reasons that chimps and humans are different is because our DNA sequence is different, not because our DNA methylation patterns are different.
In HGT mutations can take part, but also information can pave the way to new combinations that tend to be useful. HGT is random with respect to fitness as exemplified by ERV's found in the human genome.
My 'ramblings' can be put under falsification procedures , So what are the falsifications?
It is nice to hear that information reaches to the cell and is handled by it , through DNA sequence. Its a good start we agree at.
Where it concerns evolution, information is transferred through natural selection. This is the process by which random mutations are filtered through environmental information.

There is not empathy in bacteria, but there are chemicals, the enginnering systems (precursors of neural tissue) and maybe others as well. So show us how these engineering systems guide mutations so that they only produce specific beneficial mutations in a given environment, and only those mutations.

I don't denay natural selection. But i don't think is the only way. Then demonstrate, WITH DATA, what the other way is.

Not only by natural selection.By direct influence from environment(namely through information) as well , according to epigenesis to Shapiro, Barbara wright, Yablonka, Pigliucci, Weismann (father of MD theory), Darwin. Epigenesis DOES NOT CHANGE THE DNA SEQUENCE. Chimps and humans are different because our DNA sequences are different. Therefore, your theory is meaningless for explaining the differences between species. IOW, your theory is useless as it relates to evolution.

Question to zi ko:
With the right empathic input, could a human give birth to a zebra?

Iquote from Wikipedia: 'These changes may remain through cell divisions for the remainder of the cell's life and may also last for multiple generations Yes, multiple generations as in 3-5 generations, at most. That is not permanent. Epigenetics deals with DNA methylation and histone packaging, not with DNA sequence.
In HGT mutations can take part, but also information can pave the way to new combinations that tend to be useful. They can also pave the way to new combinations that are neutral and detrimental with respect to fitness, otherwise known as random mutations.
Epigenetic changes have also been observed to occur in response to environmental exposurefor example, mice given some dietary supplements have epigenetic changes affecting expression of the agouti gene, which affects their fur color, weight, and propensity to develop cancer. A change in gene expression is not the same as DNA mutation.

As informations role is gradually and finally being accepted, empathy will inevitably the next step. Not until you demonstrate a mechanism by which emotions in the brain can cause specific mutations in sperm and ova. Where is that mechanism?

1. If in mean time a mutation happens there is permanent genotypic and phenotypic change.
DNA mutation is NOT epigenetics.
2.Epigenetic changes accumulating and lasting for 3-5 generations push organism for mutations at a special direction, or /and increasing mutation rate and consequently,if we stick to randomn mutations, to" chose" the beneficial ones This choosing is coordinated by genome environment. So the result isin any case, function driven evolution. Sticking in randomness becomes an act of plain belief, as it cannot be proved by testing.
The organism does not choose to only produce beneficial mutations. You are making stuff up.
As my theory does not exclude randomn mutations it can go along with mathematicians '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. ( Barbara Wright). And where is the data to back up this claim?

By the time information's role and mechanisms will establish, the only thing i have to prove is the existance of empathy.
That mechanism has already been established. The flow of information in evolution moves from the environment to the population's genome through natural selection. It has nothing to do with empathy. Edited by Taq, : No reason given.
