First go read this. Epigenetics focuses on the idea of meaningful genetic change being passed down the generations by means other than DNA. Lamarckism is the supposedly discredited thinking that change to an organism in a single lifetime can also be inherited.
The article suggests that life has developed methods to transfer by reproduction not only genetic information, but even the experiences of the parents, a form of actual knowledge.
The significance of this is difficult to downplay, and the ramifications are going to keep people occupied for a long time. This is something traditionally fantastical, hard sci-fi at best. Before I come back to what this could really mean, a quick detour through gaming.
