DHW: I don’t know why you think epigenetics runs counter to the theory of common descent, since it only explains how existing organs can make changes to themselves. As regards genes, I’m surprised that similar (or the same) genes preclude relationship. Why? I’d have thought it was the similarity or the sameness that supported common descent.

Tony: Epigenetics does NOT add new information to DNA, meaning it can not explain an increase in complexity of information.

Epigenetics can change the expression of a gene, which means methylation brings out other existing information which the gene contains. This is where I see God's pre-planning.
