Polinski 41 Posted June 30, 2019 What enables them. That is to say as with the mouse experiments how does a learned fear of cherry blossoms get from the mind of a Male mouse to its sperm and offspring? Noting that the mutated Gene's are not random mutations.... https://www.nature.com/news/fearful-memories-haunt-mouse-descendants-1.14272 0 Share this post Link to post Share on other sites

Noting that the mutated Gene's are not random mutations.... I don't think all of the mechanisms involved are fully understood yet. However, I doubt it gets "from the mind" to the sperm cells, more likely that the triggering event (pain, in this case) causes changes in both. Also, note that there are no mutated genes involved (that is why it is called "epigenetics"). I doubt it is "instant" either. The mice had to learn to associate the smell and the pain over a period of time; no doubt time is also required for the epigenetic modification to occur. This might be a good resource to learn more: https://www.whatisepigenetics.com/fundamentals/ (Hopefully, someone with more expertise will be along soon!) 0 Share this post Link to post Share on other sites

Pain is a trigger however the mind must be involved because a particular smell is involved that has to be remembered and transmitted to the sperm. Pain and smell have the mind in common 0 Share this post Link to post Share on other sites

Polinski 41 Posted June 30, 2019 (edited) 14 minutes ago, Strange said: Pain and smell can affect things other than the brain. But the smell must be smelled and comprehended by the brain, just as the pain must be felt and associated with the smell. This can only happen in the brain which is the common denominator linking the two. None of this makes any sense when compared to our current understanding of how DNA changes.
