Experiments showed that a traumatic event could affect the DNA in sperm and alter the brains and behaviour of subsequent generations.
A Nature Neuroscience study shows mice trained to avoid a smell passed their aversion on to their “grandchildren”.
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.
