"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. In HGT mutations can take part, but also information can pave the way to new combinations that tend to be useful.- My 'ramblings' can be put under falsifibility procedures , where your "assertions" can not.Your Theory is doomed tolpass the falsification test only when my theory fails it. 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. Edited by zi ko, : No reason given.

"Epigenetics can in some cases producee permanent and inhertable changes. " No, it can't. 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 In HGT mutations can take part, but also information can pave the way to new combinations that tend to be useful. ...Although epigenetics in multicellular organisms is generally thought to be a mechanism involved in differentiation, with epigenetic patterns "reset" when organisms reproduce, there have been some observations of transgenerational epigenetic inheritance (e.g., the phenomenon of paramutation observed in maize). Although most of these multigenerational epigenetic traits are gradually lost over several generations, the possibility remains that multigenerational epigenetics could be another aspect to evolution and adaptation.....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. More than 100 cases of transgenerational epigenetic inheritance phenomena have been reported in a wide range of organisms, including prokaryotes, plants, and animals. ' HGT is random with respect to fitness as exemplified by ERV's found in the human genome.
"My 'ramblings' can be put under falsifiability procedure." So what are the falsifications? My theory about empathy ca be tested as right or wrong so the theory can be substantiated or not. Your randommness theory in evolution as the only way, is a belief , so it is not falsfiable, and so incoplete .
"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. When Darwin says that he shares in some cases Lamarcks ideas, you can't mean that he meant he shared Lamarck's ideas of natural selection! -------------------------------------------------------------------------------- Information: It is time its undeservedly neglectet powerful role to evolution to be restored.

"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 suggest an article by James Shapiro THE THIRD WAY (wikipedia) Nobody says that mutations can not be detrimental in spite of 'information function driven evolution'.-------------------------------------------------------------------------------- Information: It is time its undeservedly neglectet powerful role to evolution to be restored.

"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. The above mentioned know how environment CAN affect species evolution , you can learn from them. Perhaps you can legitimally criticise only my propose of empathy's role in evolution. -------------------------------------------------------------------------------- Edited by zi ko, : No reason given.

Re: Information's role--------------------------------------------------------------------------------
What I don't understand is why you think empathy is anything other than a cognitive process. Does the cognitive process of liking cheese also affect the genome? Your idea seems, to me as informative as homeopathy: both of you have an idea that 'something' does 'something' but have yet to provide a mechanism for the 'something' doing 'something'. To be specific homeopathy states that water can take to properties of another chemical even when there is no mechanism for the transfer of properties. Homeopathy does not have a mechanism for this effect but they assert that the water has a memory. You have no mechanism for the genome being effected but you assert that it is empathy. Does this make it any clearer why people are not patting you on the back and handing you a Nobel Prize? As informations role is gradually and finally being accepted, empathy will inevitably the next step. At the moment is a proposition. -------------------------------------------------------------------------------- Edited by zi ko, : No reason given.

"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. 1. If in mean time a mutation happens there is permanent genotypic and phenotypic change.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. 3. Same information passed empathecly over many generations on widespread species numbers it is propable to have special affect, maybe permanent, on genome. Nobody knows for sure that this new notion is wright or wrong. Research will show. Blind belief to one or other direction doesn' help.
"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. 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.

"As informations role is gradually and finally being accepted, empathy will inevitably be 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? By the time information's role and mechanisms will establish, the only thing i have to prove is the existance of empathy. -------------------------------------------------------------------------------- Information: It is time its undeservedly neglectet powerful role to evolution to be restored.

"1. If in mean time a mutation happens there is permanent genotypic and phenotypic change." DNA mutation is NOT epigenetics. It is an example( from wikipedia) in how epigenetically acquired traits are incorporated to DNA.
"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" choose" the beneficial ones This choosing is coordinated by genome environment. So the result is in 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. 'Choosing' and 'deciding' is according to Shapiro are intergrated functions of bacteria and higher organisms.
"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? This claim is made by a scientist. Where are the data to disclaim this?

"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. You ignore my arguments. I say Darwin himself and others contemporary to us scientists share Lamarcks wiews on evolution, who obviously thought his evolution theory based o information from environment in terms differrent than natural selection , Darwin did not always talk about evolution strictly in terms of natural selection and mutations.

I don't mean this type of information, but direct information, as that it takes place in epigenetics and asLamarck had thought it.

If your argument is "because Darwin said so" then it should be ignored. Darwin got a lot wrong. We have moved past Darwin. Please fast forward from the 19th century to the 21st century. Isaid Darwin and other contemporary scientists. I make the question more precise and i think it is very crucial to our discussion: 1. Do you think that epigenetic biologists ACCEPT OR NOT that environment affects genome in a wide sense? 2.If yes, by which mechanism? By neural system or other wise?( we are talking about eucaryotes). I hope for a clear answer.--------------------------------------------------------------------------------

Yes. By natural selection. Could you answer a question for me? What makes you think empathy is what affects evolution? Why not something else? --------------------------------------------------------------------------------Natural selection selects after genotype (by mutations) or phenotype (by paramutation ect) change. I mean direct effect. Empathy is a type of information connected with organism survival. It is usefull to life and i believe nature in its economy wouldn't let it to be wasted. Also nature loves continuity and empathy is an evolutional continuant of information. Empathy acting over long time periods on same genomic place can have a permanent effect .
