Epigenetics

Some basic knowledge for fashionista advocates of epigenetics who indeed never learned genomics but emphasize methylation because they refuse any gene determination...
Epigenetics is an important part of genetics. It’s one of a few mechanisms by which DNA receives instructions from the environment, but in recent years, it has become fashionable to question whether epigenetic stamps can be passed on to offspring after having been acquired during life, and thus might be a kind of neo-Lamarckian evolution. There is some evidence that some epigenetic traits are passed on, but none that these are permanent. Thus, there is no evidence that Lamarckian inheritance is correct, nor has any impact either on natural selection or the robustness of Darwinian evolution.
