I think this is the epigenetic inheritance that we talked about here a couple of years ago, that Marcus Pembrey is associated with. These mice are not inheriting 'memories' from their parents; their parents had experiences, apparently fairly traumatic, that caused changes in their genetic material (though not changing the DNA sequence) which then lead to behavioral changes in the next generation. Important, yes, and arguably ground changing for evolutionary biology. But it doesn't mean that I have a memory for experiences my father had.
