I was invited today onto public radio's The Takeaway with the great John Hockenberry to discuss a new Nature Neuroscience study from Emory University demonstrating that memories can be biologically inherited, via epigenetics, from parent to child and even to grandchild. For those of you already familiar with fourteen years of epigenetic studies, this is mostly just further proof that epigenetic inheritance is very real. For those who have not yet heard of epigenetics, or genetic expression, I promise that this will blow your mind. The 20th century was about genetics. The 21st is going to be about epigenetics.
