Това не е нова идея, но проучването е хубаво обобщение на последните разработки в тази област и показва, че старата идея за унаследяване, ориентирана към гените, бавно се заменя с много по-богата теория за това как организмите взаимодействат със средата и как предават тази информация на поколенията. Това е много „плашещо“ развитие, както се казва в самата статия. След като хората осъзнаят истинското въздействие на ежедневния стрес и травми, които преживяват в ръцете на корумпираното си правителство, работодател, социална мрежа и т.н., отговорностите за виновните субекти ще бъдат огромни и социалната динамика/структура вероятно ще се промени радикално.

“…That idea would have been laughed at 20 years ago. But today the hypothesis that an individual’s experience might alter the cells and behavior of their children and grandchildren has become widely accepted. In animals, exposure to stress, cold, or high-fat diets has been shown to trigger metabolic changes in later generations. And small studies in humans exposed to traumatic conditions—among them the children of Holocaust survivors—suggest subtle biological and health changes in their children. The implications are profound. If our experiences can have consequences that reverberate to our children or our children’s children, that’s a powerful argument against everything from smoking to immigration policies that split families. “This is really scary stuff. If what your grandmother and grandfather were exposed to is going to change your disease risk, the things we’re doing today that we thought were erased are affecting our great-great-grandchildren,” says Michael Skinner, a biologist at Washington State University in Pullman. Skinner’s own research in animals suggests changes to the epigenome, a swirl of biological factors that affect how genes are expressed, can be passed down through multiple generations. If trauma can trigger such epigenetic changes in people, the alterations could serve as biomarkers to identify individuals at greater risk for mental illness or other health problems—and as targets for interventions that might reverse that legacy.”
