I'll take the bait. It seems to me that going from "F1 and F2 generations of mice respond differently to the smell of acetophenone if their parents were exposed to it" to "well, human trauma is inherited and there isn't anything we can do about violent behavior" is somewhat far-fetched and smells like neo-eugenics. |

> In summary, we have begun to explore an under-appreciated influence on adult behavior—ancestral experience before conception. From a translational perspective, our results allow us to appreciate how the experiences of a parent, before even conceiving offspring, markedly influence both structure and function in the nervous system of subsequent generations. Such a phenomenon may contribute to the etiology and potential intergenerational transmission of risk for neuropsychiatric disorders, such as phobias, anxiety, and post-traumatic stress disorder. To conclude, we interpret these results as highlighting how generations can inherit information about the salience of specific stimuli in ancestral environments so that their behavior and neuroanatomy are altered to allow for appropriate stimulus-specific responses.
