Epigenetics is actually pretty cool stuff.

Let's get concrete with an example first. Plant a human fetus in the womb of a gila monster. Do you get a half-human, half lizard? No. You get a dead baby and a very sick lizard.

Epigenetics is (roughly!) the observation that some of the blueprint for that marvelous complicated boostrapping task of building a human being from another human being is contained not in the fertilized egg, but in the environment around it.

It is almost an Ouroboros of an idea. Significant moments in the unfolding construction of the fetus are signaled for not from within the genetic code of the fetus, but by the surrounding chemistry of the womb. Which are in turn carried as excess baggage in the genetics of the baby, to be claimed when it is of age to have children itself.

Another way to look at it is as a second code, a sort of oral history of the flesh; information that is carried only by a shape of a protein formed by being around a previous protein that was also folded that way.

Nothing that new, really. We also carry around alien DNA in the form of our mitochondria, and in our complement of intestinal flora and fauna (many of which are transmitted not via genetics or blood but later, as a form of cross-contamination between mother and child, or even between family and child).

It may take a village to raise a child, but it also takes a whole team of different sources of developmental and phenotypical information.



And I am happy that science is busy discovering more and more new things it didn't know before, and happily throwing itself into the questions. Unlike what the OP apparently wishes, which is to turn our backs on all Creation with a grumpy "guess it will have to be a mystery, then."
