LOL!!! This is some next level ignorance, dude. You just repeat your original lie that was literally just proved wrong by the article I posted.
You don't have a clue about genetics or epigenetics.
You seriously can't make this stuff up, people...

Where was I wrong in my analysis about epigenetic inheritance

You blindly ignore the articles that explain evolution in viruses and then demand we prove YOU wrong instead of looking at the research.
But flu viruses replicate quickly and have a high rate of genetic changes, or mutations, so the helpful antibodies you may have developed to a previous year's strains often can't attach to this year's mutated viruses. Such adaptation helps the flu virus thrive in its environment. It survives, infects and multiplies. In other words, it evolves.

Sorry just to probe further , do you mean Paul as in the book of Paul , as in the disciple of Jesus christ ?
Did he say as much ?

In viruses
Different virus families have different levels of ability to alter their genomes and trick the immune system into not recognizing. Some viruses have relatively unchanging genomes like paramyxoviruses while others like influenza have rapidly changing genomes that inhibit our ability to create long lasting vaccines against the disease. Viruses in general have much faster rate of mutation of their genomes than human or bacterial cells.
In general viruses with shorter genomes have faster rates of mutation than longer genomes since they have a faster rate of replication.[15] It was classically thought that viruses with an RNA genome always had a faster rate of antigenic variation than those with a DNA genome because RNA polymerase lacks a mechanism for checking for mistakes in translation but recent work by Duffy et al. shows that some DNA viruses have the same high rates of antigenic variation as their RNA counterparts.[15] Antigenic variation within viruses can be categorized into 6 different categories called antigenic drift, shift, rift lift, sift, and gift
Antigenic rift: Recombination of viral gene. This occurs when there are again two viral cells that infect the same host cell. In this instance the viruses recombine with pieces of each gene creating a new gene instead of simply switching out genes. Recombination has been extensively studied in avian influenza strains as to how the genetics of H5N1 have changed over time.[16]
Antigenic drift: point mutations that occur through imperfect replication of the viral genome. All viruses exhibit genetic drift over time but the amount that they are able to drift without occurring a negative impact on their fitness varies between families.
Antigenic shift: reassortment of the viral genome that occurs when a single host cells is infected with two viral cells. As the viral cells go through replication they reassort and the genes of the two species get mixed up and make 256 new variations of the virus. This occurs in influenza every couple of decades.
Antigenic sift: direct transmission with a zoonotic strain of a virus. This occurs when a human is infected during a spillover event.
Antigenic lift: Viral transmission of host derived gene. Some viruses steal host genes and then incorporate them into their own viral genome, encoding genes that sometimes give them an increased virulence. An example of this is the pox virus vaccinia which encoded a viral growth factor that is very similar to the human growth factor and thought to be stolen from the human genome.[17]
Antigenic gift: Occurs when humans deliberately modify a virus's genome either in a lab setting or in order to make a bioweapon.

so I posted several peer reviewed research papers backed up that fact and you dismissed them all blindly.
Thanks for proving yourself a complete ignoramus.

AS far as I understand your posts , you are asserting that viruses dont evolve , and that they simply change their surface proteins through the various antigenic phases to resist antigens from the hosts immune system

it seems as thought its far more complex than you or I can comprehend
mutations arent as random as once believed either .

I get what you are saying about how random mutations couldnt give rise to the diversity of life due to their randomness but the rate at which these mutations occur is extremely quick
and that geneticist are now saying mutations may not be as random as they once thought
gentic variation and random mutation
ANyway work is finished I better catch the trian
great subject and good info to digest over the weekend in your links , ill be reading about it over the weekend and get back to you with my thoughts
Take care mate
Peace

Not letting you get away with lies like this. The papers you presented only had access to the abstract. I made my case based off what is present in the abstract and still managed to give you the reasons why I thought their conclusions were unfounded. Respond to that.
You can't keep up with a scientific discourse, that's ok. But don't go insulting people to hide that fact.

That is completely irrelevant. They are still peer reviewed experiments and research. If you search you can find copies of them. Just because you can't access the whole thing, doesn't mean I lied.

Stop trolling. Stop barcing. If you want to discuss science find a paper that is accessible and explain why the observable evidence supports your position.
