The joys of epigenetics

I've been involved in a personal and social debate for years around the issue of inherited traits. Much opposed to the concept of sociobiology,I've always been taken with the outlook advocated by Stephen Jay Gould and Richard Lewontin.
But in like manner is the new science of Epigenetics

Epigenetics is the study of epigenetic inheritance, a set of reversible heritable changes in gene function or other cell phenotype that occur without a change in DNA sequence (genotype). These changes may be induced spontaneously, in response to environmental factors, or in response to the presence of a particular allele, even if it is absent from subsequent generations.
If you're partial to a little bit of Lamarckism to balance the genetic passivity presumed in Darwinism then maybe epigenetics is right up your alley.

I'll come back to this topic later in the context of a real application and the problems of so many conundrums raised by the rigid determination that genes control our fate.
