[Xmca-l] Re: Scientists find that memories may be passed through DNA



Thanks to Jenna for raising this and Mike for providing the 1951 paper.

I had to go searching for a more basic description of *transgenerational
epigenetic inheritance* in order to understand the debate (and the paper
Mike sent along). I think I found a good one (excellent science
popularization, in my view), which I share with you here, in case others
are both as curious AND uninformed as I.
