A controversial view of epigenetic inheritance

A critical view on transgenerational epigenetic inheritance in humans

A new article in Nature suggest that more evidence is needed to ascertain the role of epigenetic inheritance.
Even if the molecular mechanisms exist to transmit epigenetic information across generations in humans, it is very likely that the transgenerational transmission of culture by communication, imitation, teaching and learning surpasses the effects of epigenetic inheritance and our ability to detect this phenomenon. Cultural inheritance has certainly had an adaptive role in the evolution of our species, but the evidence for transgenerational epigenetic inheritance, as laid out above, is not (yet) conclusive. 
Let's wait for new evidence...
