“STANDARD EVOLUTIONARY THEORY has long regarded inheritance mechanisms outside genes as special cases; human culture being the prime example. The Extended Evolutionary Synthesis explicitly recognizes that parent–offspring similarities result in part from parents reconstructing their own developmental environments for their offspring. ‘Extra-genetic inheritance’ includes the transmission of epigenetic marks (chemical changes that alter DNA expression but not the underlying sequence) that influence fertility, longevity and disease resistance across taxa.”
