You Might Have Inherited Your Ancestors’ Fears

While not widely accepted in psychiatric circles, C.G. Jung’s theories about “racial memory” (more commonly known now as “genetic memory”) became a popular trope in the writings of writers like Robert E. Howard, Jean Auel, and Frank Herbert, all of whom used it to introduce things into their stories that their characters might not otherwise know. Now it seems that a couple of scientists may have proven that there is at least some truth to the idea that we can inherit memories of a sort from our ancestors.

Via Discover Magazine:

Geneticists were especially surprised to find that epigenetic change could be passed down from parent to child, one generation after the next. A study from Randy Jirtle of Duke University showed that when female mice are fed a diet rich in methyl groups, the fur pigment of subsequent offspring is permanently altered. Without any change to DNA at all, methyl groups could be added or subtracted, and the changes were inherited much like a mutation in a gene.

Hold That Cheeseburger: Your Diet Can Change Your Future Kids’ DNA

Via LiveScience:

You are what you eat. Or rather, your children will be. Animal experiences seem to suggest that an individual’s dietary habits can actually change their DNA, leading to greater risks for mutations in subsequent generations. Does this mean that you’re doomed to have a McBaby? No, not necessarily: With the right food choices the genetic changes may be beneficial as well.

“It is possible that eating more omega-3 fatty acids, choline, betaine, folic acid and vitamin B12, by mothers and fathers, possibly can alter chromatin state and mutations, as well as have beneficial effects…leading to birth of a ‘super baby’ with long life and [lower risk] of diabetes and metabolic syndrome,” Singh told LiveScience. “This is just a possibility, to be proven by more experiments.”
