Faulty imprinting is caused by drugs, environmental pollutants and other hormone-like molecules  present in excess at the critical periods with lifelong receptorial, morphological, biochemical and behavioral consequences. HI is transmitted to the hundreds of progeny generations in unicellulars and (as proved) to a few generations also in mammals.
Faulty imprinting is caused by drugs, environmental pollutants, and other hormone-like molecules present in excess during critical periods, leading to lifelong consequences affecting receptors, morphology, biochemistry, and behavior.  Imprinting can be passed down through generations of unicellular organisms and a few mammalian generations.
