On epigenetics

Here is an interesting discussion of a recent paper on the operational and theoretical definitions of “epigenetics”. This term – which has a deep history, well before genetics – is interpreted in every manner from inherited histone patterns on chromosomes to parental investment and extrasomatic inheritance. The authors of the discussed paper go towards the former extreme, while Eva Jablonka goes for the other. It’s always fun to see scientists arguing over terms.
