You have just described a genetic change that only last two generations. If as you say it does not effect the DNA sequence, what is happening? The only way that sperm moves info is thru it's DNA, unless another path is discovered?

It affects gene expression.

I am sorry you keep refusing to accept it but they found what they believe is an epigenetic marker on the olfr151 gene of the sperm.
This is not the first thing supporting epigenetics.
Lets say there is a genetic marker on the sperm, I would not really dispute that, as the sex cells must be involved. The fucking question that you can not grasp is, what is the mechanism by where a fucking bad memory stored in the brain modifies sperm that grow in the testes? The marker is not the question, the question is how does the marker get inside of the DNA in the first place................................

These modifications, which can dial the expression of particular genes up or down, are known as epigenetic mechanisms. Certain environments or experiences can trigger the attachment of chemical markers to a gene that controls whether that gene will be used to make proteins (the building blocks of the body's tissues). [The Top 10 Worst Hereditary Conditions]
"Depending on the environment an organism finds itself in, that gene might be turned on or off," study researcher Brian Dias of Emory University School of Medicine in Atlanta, told LiveScience. "It behooves ancestors to inform their offspring that a particular environment was a negative environment for them," Dias said.

Epigenetics literally means "above" or "on top of" genetics. It refers to external modifications to DNA that turn genes "on" or "off." These modifications do not change the DNA sequence, but instead, they affect how cells "read" genes.
Examples of epigenetics
Epigenetic changes alter the physical structure of DNA. One example of an epigenetic change is DNA methylation — the addition of a methyl group, or a "chemical cap," to part of the DNA molecule, which prevents certain genes from being expressed.
Another example is histone modification. Histones are proteins that DNA wraps around. (Without histones, DNA would be too long to fit inside cells.) If histones squeeze DNA tightly, the DNA cannot be "read" by the cell. Modifications that relax the histones can make the DNA accessible to proteins that "read" genes.
Epigenetics is the reason why a skin cell looks different from a brain cell or a muscle cell. All three cells contain the same DNA, but their genes are expressed differently (turned "on" or "off"), which creates the different cell types.
Epigenetic inheritance
It may be possible to pass down epigenetic changes to future generations if the changes occur in sperm or egg cells. Most epigenetic changes that occur in sperm and egg cells get erased when the two combine to form a fertilized egg, in a process called "reprogramming." This reprogramming allows the cells of the fetus to "start from scratch" and make their own epigenetic changes. But scientists think some of the epigenetic changes in parents' sperm and egg cells may avoid the reprogramming process, and make it through to the next generation. If this is true, things like the food a person eats before they conceive could affect their future child. However, this has not been proven in people.
Epigenetics and cancer
Scientists now think epigenetics can play a role in the development of some cancers. For instance, an epigenetic change that silences a tumor suppressor gene — such as a gene that keeps the growth of the cell in check — could lead to uncontrolled cellular growth. Another example might be an epigenetic change that "turns off" genes that help repair damaged DNA, leading to an increase in DNA damage, which in turn, increases cancer risk.
Dude this is not about a gene being turned on or off, it is about a change to sperm cells. See the baby mouse was never exposed to the cherry smell, thus it can not be influencing it's genepool. The exposure happened in the adult.
You go right from saying that this is done by epigenics, to it is done by gene expression, you babble on and on. The fact is that a memory is passed to an offspring, which causes a mouse to flee a smell that it has never smelled, but that was smelled by it's father and determined to be a bad thing. Fear is thus traveling thru DNA, turning on and or off any or every gene will not create a memory of cherry blossoms. Give up, you can not create information that is not yet in the scientific knowledge base just to win a nothing less argument with me.
The same thing happens to people as well.

Genetic changes stemming from the trauma suffered by Holocaust survivors are capable of being passed on to their children, the clearest sign yet that one person’s life experience can affect subsequent generations.
The conclusion from a research team at New York’s Mount Sinai hospital led by Rachel Yehuda stems from the genetic study of 32 Jewish men and women who had either been interned in a Nazi concentration camp, witnessed or experienced torture or who had had to hide during the second world war.

They also analysed the genes of their children, who are known to have increased likelihood of stress disorders, and compared the results with Jewish families who were living outside of Europe during the war. “The gene changes in the children could only be attributed to Holocaust exposure in the parents,” said Yehuda.
Holocaust survivors' grandchildren call for action over inherited trauma

Her team’s work is the clearest example in humans of the transmission of trauma to a child via what is called “epigenetic inheritance” - the idea that environmental influences such as smoking, diet and stress can affect the genes of your children and possibly even grandchildren.
The idea is controversial, as scientific convention states that genes contained in DNA are the only way to transmit biological information between generations. However, our genes are modified by the environment all the time, through chemical tags that attach themselves to our DNA, switching genes on and off. Recent studies suggest that some of these tags might somehow be passed through generations, meaning our environment could have and impact on our children’s health.

Other studies have proposed a more tentative connection between one generation’s experience and the next. For example, girls born to Dutch women who were pregnant during a severe famine at the end of the second world war had an above-average risk of developing schizophrenia. Likewise, another study has showed that men who smoked before puberty fathered heavier sons than those who smoked after.
The team were specifically interested in one region of a gene associated with the regulation of stress hormones, which is known to be affected by trauma. “It makes sense to look at this gene,” said Yehuda. “If there’s a transmitted effect of trauma, it would be in a stress-related gene that shapes the way we cope with our environment.”
They found epigenetic tags on the very same part of this gene in both the Holocaust survivors and their offspring, the same correlation was not found in any of the control group and their children.
So we should ignore the author of the study and let you tell us?
Yeah, epigenetics are believed to regulate gene expression. That's not babble.
There is no memory, fucktard. No one said anything about fleeing either. It appears you made that up.
Yeah and??? There were no reports that any of these holocaust ancestors had actual memories of the holocaust either. They showed signs of epigenetic changes .
The author of the study can only say that something is happening, a 5 year old could say that something is happening based upon the evidence. There is no known way to create a fear of a smell by turning on or off a gene. In fact humans can smell at least one trillion scents. There are not enough genes to enable this as there are only 19 to 20 thousand human genes. Mice may have more or less ability to smell, but it doesn't matter because the deficit of genes to possible smells is too great.
Another fail, try again kid

Dias and Ressler took advantage of previous research on the biology of odor detection. Scientists knew that the chemical acetophenone, which smells somewhat like cherry blossom, activates a particular set of cells in the nose and a particular "odorant receptor" gene in those cells.
...
Dias discovered that the DNA from the sperm of smell-sensitized father mice is altered. This is an example of an "epigenetic" alteration, found not in the letter-by-letter sequence of the DNA, but in its packaging or chemical modifications.
In mice taught to fear acetophenone, the odorant receptor gene that responds to acetophenone has a changed pattern of methylation: a chemical modification of DNA that tunes the activity of genes. However, it's not clear whether the changes in that gene are enough to make the difference in an animal's odor sensitivity.
"While the sequence of the gene encoding the receptor that responds to the odor is unchanged, the way that gene is regulated may be affected," Ressler says. "There is some evidence that some of the generalized effects of diet and hormone changes, as well as trauma, can be transmitted epigenetically. The difference here is that the odor-sensitivity-learning process is affecting the nervous system – and apparently, reproductive cells too -- in such a specific way."

I was agreeing.....there is nothing to extrapolate as far as the "scientific method" is concerned. All facts of science are demonstrable through only one of two sources.....observed, repeatable experimentation ending with constant results indicating a source of Calibrating certain truths known as FACTS. The other source of confirming a fact of physical science is the observed "potential" of any phenomenon that can't be observed physically but can be quantified via the reality of mathematical science. Its the method used to calibrate the uses of atomic energy....to forecast the weather....to use light as an instrument to calculate distance that is beyond our sphere of physical capabilities to measure......the unseen power of electricity...etc.,
Thus.....the suggestion that Alien Life is responsible for life on earth still does not address the reality of physical science and the laws of physics. Where did the Aliens come from, Where did the alternate universes come from, where did the original source of energy come from that supposedly caused everything? One can extrapolate to infinity and still Science and Physics mandate there must be a superior force to that which is CREATED. All one ends up in any valid conclusion void of applying Science is a paradox of reason and logic. All Science can do is conclude as truth...... is to extrapolate through reason and logic (prima facie...beyond reason to doubt), that the physical universe was created/caused by a superior force to nature...i.e., a SUPER-Natural force. There is more than doubt to suggest that EVERYTHING witnessed today by man was caused/created randomly from "NOTHING"....as science proves, if nothing is what you start with....nothing is what will always be.........

But you demand it is not about that. Who should we believe?
Who said that each gene had one scent, nitwit?
Read what you copied and pasted...

Nothing in that describes how the change happens, this is what concerns me, as this knowledge will revolutionize the understanding of how DNA works.
You keep on providing evidence that a change happens, I have never disputed this once, but no one knows how fear travels thru generations, or how fear knows what gene to turn off even if this is what is happening, there seems to be an active unconscious controlling code working here, understanding the code is the key, we already know the results of the code which is all you are pointing too

Yes, it does. I am sorry if it sounds like gibberish to you but there it is in bold. DNA Methylation is an epigenetic mechanism that effects gene expression usually by repressing gene transcription.
http://www.whatisepigenetics.com/dna-methylation/
Who said fear knows anything? How can emotion know? What are you talking about?
There were changes in the mouse taught to fear the scent.
That seems to have affected their sperm and so the epigenetic effects were passed to their offspring.
I am sorry if you are too stupid to understand it.
http://news.emory.edu/stories/2013/12/smell_epigenetics_ressler/campus.html
No one understands how fear alters DNA or causes positive and decisive but non random changes to offspring. Including you, what befuddles me is exactly what you are so scared about protecting or evading from questioning. You copy and past stuff that you can not spell very well though, of that I must admit.
So how do Holocaust survivors transmit stress to their children? are cherry blossoms involved?
Correct, we know that it happens, but that is not the same as knowing how. The Sun used to be a God that went to sleep at night and woke up in the morning, we have no better idea what is happening here then the humans did that believed that. This is hard for some people to admit, the fact is that we do not know what we are, where we came from, or where we will end up. To admit this is to be on the right path, those who know everything have nothing to learn...............
What the researchers don't know yet:
Are these effects reversible – if sensitized parents later learn not to be afraid of an odor, will effects still be seen in their pups?
Does it only happen with odors? Could mice trained to be afraid of a particular sound, for example, pass on a sensitivity to that sound?
Do all the sperm or egg cells bear epigenetic marks conveying odor sensitivity?
How does information about odor exposure reach the sperm or eggs?
Bullshit. We have a better theory and understanding of epigenetics than that. You claim to know more than the study's authors but there is no sign of that.
No theory is knowing...............................so as I said, no one knows as you have just admitted
Holy fuck! You are dense! Again, it is not fully understood, but they have some ideas. You have been misrepresenting this study from the start and you don't understand what it demonstrates or what the authors suggest.
Did you read what you quoted?

Their ideas are all theory, in fact we may have no clear idea how DNA works at all. This shows that clearly.
