Trauma May Be Woven Into DNA of Native Americans

Trauma is big news these days. Mainstream media is full of stories about the dramatic improvements allowing science to see more clearly how trauma affects our bodies, minds and even our genes. Much of the coverage hails the scientific connection between trauma and illness as a breakthrough for modern medicine. The next breakthrough will be how trauma affects our offspring.

The science of epigenetics, literally “above the gene,” proposes that we pass along more than DNA in our genes; it suggests that our genes can carry memories of trauma experienced by our ancestors and can influence how we react to trauma and stress. The Academy of Pediatrics reports that the way genes work in our bodies determines neuroendocrine structure and is strongly influenced by experience. [Neuroendocrine cells help the nervous and endocrine (hormonal) system work together to produce substances such as adrenaline (the hormone associated with the fight or flight response.] Trauma experienced by earlier generations can influence the structure of our genes, making them more likely to “switch on” negative responses to stress and trauma.
