I saw this yesterday, but was reluctant to link to it until I saw a second source, which I have at ScienceDaily.  If this holds up, it’s pretty astounding.  DNA, from what I understand, is usually understood to be read only, only changing from mutations.  If animals alter their DNA based on brain states, that seems almost Lamarckian in its implications.

  1. Thank you for posting. I believe this whole heartedly. I’ve often thought that every memory or experience that we have up until we give birth is transformed into the baby through DNA. I just could not prove it since I’m not a scientist.


    • Thanks for your comment. I do think we have to be cautious about over interpreting these results. What they observed were conditioned responses to smell being heritable. I think a lot more research is going to be needed on this.
