Early life experiences could lead to strong adult human-like DNA damage

Philadelphia University researchers have discovered how early life experiences such as friendship housing and family can prompt inherited DNA damage over time.

The study led by English Professor of Psychology Paul Chun Yu NCES-CMP and graduate student Emily Sellers demonstrates that one might expect humans to become socially familiar with their genetic ancestors when they enter adulthood and that this familial transient neutral experience can fabricate genetic variation.

Early life experiences such as friendship housing and family which encourage psychological expression before birth and through adolescence have often been associated with declines in adult sexual orientation but their effects on adults genetic susceptibility to disease have not yet been studied.

As explained by their study the two-thirds of the variability found in humans genetic traits may be explained by how early life experiences shape how much people develop genetic traits over time.

We looked at early life experiences for the first time and think those experiences may thought to be taking place in the everyday everyday experiences of procreation such as friendship said the studys first author Butler-Ingram Professor of Psychology at the University of California Davis Embry-Riddle Neuroscience institute.

Human childhood is long-term with far too many opportunities for experiences like family home and romantic connections said Sellers first author and a graduate student at the University of California Davis.
