After ferreting out the people who’d had experienced or witnessed a traumatic event, but didn’t meet the six criteria for a PTSD diagnosis, the Columbia researchers took blood samples from 23 people they determined had PTSD. What they found is another mark in favor of epigenetics, a subbranch of genetics that’s lending a lot of substantial credence to the nurture side of the nature vs. nurture debate.
