There are only one or two case studies proposed for the phenomenon of
epigenetics. It may well turn out to be of minor significance. A
friend of mine is a big cheese on Epigenetics at Cardiff and I am
keeping my ear close to the ground.
It would seem that there is little survival "logic" involved in the
consequences of this phenomenon, it is hard to predict and hard to
identify. Many of the findings are not much beyond statistical error
and could easily be confused for societal changes in diet and food
availability, never before so plentiful in human history.

No one is saying that epigenetics will be found to have a great effect
on our mental capabilties or other significant factors  beyond basic
growth patterns, if then.

     I assume that those two case studies involve looking into the
known epigenetic processes of methylation, acetylation,
phosphorylation, ubiquitylation, and sumolyation of histone, which
could, potentially, lead to over 9,000 ways any gene could be
expressed?

     The cellular processes themselves have always been available.
Granted, some may occur more or less often depending on available
foodstuffs.  But the inherent variety of genetic expression is down to
the nnumber of ways in which these processes can be applied to any
gene.  It seems to me that there's a world of possible consequence.
When the terms: massively parallel signature sequencing (MPSS),
chromatin immunoprecipitation microarray analysis (ChIP-chip), DNA
adenine methyltransferase identification (Dam-ID), protein binding
microarrays (PBM)and DNA immunoprecipitation microarray analysis (DIP-
chip) become as familiar as X-Ray and MRI, we'll know a lot more about
it.

    Notwithstanding influencing disease resistence, drug resistence
and efficiency and disease etiology itself, you're probably right.

Chaz - there is massive activity in epigenetics, even an EU Centre for
it.  Biochemistry was my field and I'm still reading reports on
advances as part of my daily diet.  I was head of research innovation
(funding really) in the department for biomolecular engineering until
5 years ago.  The epidemiology studies in epigenetics are very sound,
and actual chemical pathways are being found.  There have been deep
advances in lab equipment and these are beginning to pay off.

So , what earth shattering and life changing developments are we to
expect in the next few years that justify all that navel gazing?

Neil, I'll keep my answers short, as when I ask specific questions you
don't seem to be acknowledging them at the moment.

     Breakthroughs in disease resistence, drug resistence
and efficiency and disease etiology itself, like I said.  But, I'm
sure if you heard it from Neil, you'd tend to accept it more.  Neil?

It all depends on what we are trying to grasp with the word smart.  We
have smart bombs - typically we would have through our unsmart ways of
doing things.  I would much rather we got to grips with pathological
capitalism as a first priority.  One thing I would say before
addressing where the new technologies are leading is that many of the
promises are to do with the crud one has to put in bids to get
financing and they are not real that often.
I would guess that the complex sequencing we are witnessing will break
down into a few rules - a bit like we can do with simulated bird-flock
flight.  I'll get back on what epigenetics and related chemical gene-
activity change sometime later.  Some experiments are working with
femto-laser pulses to insert genetic material and people are mucking
about with light tweazers and million shot a second photography.
Chaz sounds a bit like Habermas here - we need human values in a
lifeworld of communicative rationality and live in a systemic idiocy.
Environmental studies are beginning to show a detailed network, a
sequencing of this.  There is some kind of analogue here to the
genetic methods.
