Would you go for epi·ge·net·ics \ˌe-pə-jə-ˈne-tiks\ noun : the study of heritable changes in gene function that do not involvechanges in DNA sequence First use: 1942 Mirriam-Webster If this is going to be a PingPong my normal limit is 3 but there have been a few exceptions Please Register or Log in to view the hidden image!
Before we can analyze how epigenetics is being used by real scientists and abused by quacks, however, it’s necessary to explain briefly what epigenetics is. To put it succinctly (I know, a difficult and rare thing for me), epigenetics is the study of heritable traits that do not depend upon the primary sequence of DNA https://www.google.com.au/amp/scien...t-think-it-means-what-you-think-it-means/amp/ Read the whole reference Please Register or Log in to view the hidden image!
What is Epigenetics? Epigenetics is the study of potentially heritable changes in gene expression (active versus inactive genes) that does not involve changes to the underlying DNA sequence — a change in phenotype without a change in genotype — which in turn affects how cells read the genes. Epigenetic change is a regular and natural occurrence but can also be influenced by several factors including age, the environment/lifestyle, and disease state. Epigenetic modifications can manifest as commonly as the manner in which cells terminally differentiate to end up as skin cells, liver cells, brain cells, etc. Or, epigenetic change can have more damaging effects that can result in diseases like cancer.

Correction This is last PING unless you PONG not just another definetion of epigenetics but some understanding of what was being claimed for epigenetics in the original post and what epigenetics can actually do Which, the claim, is NOT, and never will be, the role of epigenetic changes The claim of genetic changes transfering learnt memory is fanciful or a confusion at best of the claim vs the reality Further reading * Among the several recent developments in biomedical research that are being hyped as revolutionary, the science of epigenetics has inspired the boldest claims. https://www.google.com.au/amp/s/psmag.com/amp/p/70c2cf0a3d27 Please Register or Log in to view the hidden image!

Bye bye , Tiresome . When you won't provide the # posts for your argument , your argument is weak , you are weak .
Phylogenetic memory makes up the bulk of brain and spinal cord memory (reflexes, language centers, etc...); it's different from epigenetic memory - which we know little of in humans, though it appears to work through processes such as methylation of a DNA.
Not sure that is correct but if you have any reference supporting that I would like to read it Correct but there is much research being done The action though is more about how genes are expressed not acting on the content of the DNA of the gene Methylation is one of four ways (4 from memory so I stand to be corrected if you know otherwise) Please Register or Log in to view the hidden image!
From The God Post #75 The above (if possible) would not be memory transmitted genetically. This issue seems to be one requiring extraordinary evidence. With some cogent theory & supporting evidence, it seems almost absurd to believe that learned abilities could be transmitted from the brain to either sperm or an ovum.
1. Yes, it will not be genetic transfer of memory. 2. "Almost absurd to believe" has no meaning in science.
True But even hard science looks at the not so common common sense and concludes That makes sense Please Register or Log in to view the hidden image!
Do we believe the Neurons in the brain can be in certain way more organised and this form of order will have better disposition to acquire DATA, and the individuals with different organised Neurons will be more receptive to a certain stimulus .
