Primarily genetic, environmental, or both?

A 2013 study documented by psychiatrists Brian G Dias and Kerry J Ressler, used electrical currents on the feet of male mice to harm them, while infusing their cage with a distinctive cherry blossom scent. Over several repetitions, the mice then associated the smell of cherry blossom with pain.

When exposed to the same cherry blossom scent, the 1st generation offspring of these mice then became “jumpy and nervous.” Over the long term, these same mice were witnessed to participate in risk-taking behavior and over-eating. Interestingly, these exact same two behaviors are frequently witnessed in human children of parents that experienced great trauma.

This is drawing upon more recent research which states that descendants of those living in poverty camps in Sweden and descendants of Holocaust survivors indicate a modification in their RNA molecules. This is said to be the cause of trauma stemming behavior in the long term, increased cancer and early mortality rates. Even more interestingly, when descendants were compared by biological gender — it was primarily the men that were displaying the signs and weaknesses of inter-generational trauma.

However, it is important to note that respective sample sizes of each of these human studies with descendants from particular war and poverty zones have not even exceeded…
