Could epigenetics support Lamarkian Evolution?

Jennie Brown  asked the Naked Scientists:
   
Hello!  I remember hearing about epigenetics on your program.  I was wondering if this new finding could be logically interpreted as support or partial support for Lamarkian evolution?

Epigenetics is the modification of genes without altering the DNA - e.g. acetylation, methylation etc. It is long-term and reversible, but generally occurs in differentiated cells. This means that it's unlikely to carry through the germ cells into the next generation. While experiences as a child, and therefore your parents behaviour, can indeed change our genes for a lifetime through epigenetics, there is no evidence to suggest this can be inherited (or none that I've found).
