Evidence of biological process that embeds social experience in DNA that affects entire networks of genes
(Medical Xpress)—Early life experience results in a broad change in the way our DNA is "epigenetically" chemically marked in the brain by a coat of small chemicals called methyl groups, according to researchers at McGill ...
