 Population Epigenetics?

Potential Mechanism for Population Epigenetics! I thought this paper was interesting because it relates Epigenetics to colon cancer, and how methylation can actually silence one of your DNA repair genes. The paper also shows that a mother with the methylated gene may have passed it along to her son. The son's children, however did not carry the methylated gene, possibly hinting at a "reset" of methylation during spermatogenesis. ....Or it could just be a coincidence that both mother and son acquired this methylation over their life spans, but that would be boring.

Does that paper prove that methylation being either passed onto offspring or undone (which was proven to occur in rats) also occurs in humans? Or was that already known?

The paper I am referring to...
