(My interest in evolutionary biology is quite lax, so bear with me if I say something particularly wrong.)

I was under the impression that, in recent years, there had been a small but significant surge of interest in the possibility of epigenetic inheritance, evidence for which had been found in a few studies on chickens, rats and plants. This article seems to explicitly states that no such thing is currently recognized.

Have I been deviated by fringe neo-Lamarckist press releases, are they simply too recent and in need of consolidation, or did Pinker avoid mentioning them for the sake of clarity and fidelity to the most safe, "gcd" theory?
