The most revolutionary research study to be published in at least the
last ten years. The very first proof of principle experiment,
empirical demonstration of cause and effect that conclusively
demonstrates that environmental exposures ARE inherited by ALL
subsequent generations.

Was Lamarck genetics correct?

Are the obesity and autism epidemics the result of epigenetic
transgenerational inheritance?


Epigenetic transgenerational inheritance of altered stress responses

Abstract
Ancestral environmental exposures have previously been shown to
promote epigenetic transgenerational inheritance and influence all
aspects of an individual's life history. In addition, proximate life
events such as chronic stress have documented effects on the
development of physiological, neural, and behavioral phenotypes in
adulthood. We used a systems biology approach to investigate in male
rats the interaction of the ancestral modifications carried
transgenerationally in the germ line and the proximate modifications
involving chronic restraint stress during adolescence. We find that a
single exposure to a common-use fungicide (vinclozolin) three
generations removed alters the physiology, behavior, metabolic
activity, and transcriptome in discrete brain nuclei in descendant
males, causing them to respond differently to chronic restraint
stress. This alteration of baseline brain development promotes a
change in neural genomic activity that correlates with changes in
physiology and behavior, revealing the interaction of genetics,
environment, and epigenetic transgenerational inheritance in the
shaping of the adult phenotype. This is an important demonstration in
an animal that ancestral exposure to an environmental compound
modifies how descendants of these progenitor individuals perceive and
respond to a stress challenge experienced during their own life
history.

Short Video interview with research author Michael Skinner. The
interview eventually gets into the implications of this research. Or,
how environment exposures can impact environmental epigenetics and
disease susceptibility in generations to come. A lead researcher in
the field OF Transgenerational epigenetics who gave this talk, 6
months before the current study was published.

"The most revolutionary research study to be published in at least the last
ten years. The very first proof of principle experiment, empirical
demonstration of cause and effect that conclusively demonstrates that
environmental exposures ARE inherited by ALL subsequent generations."

Only 3 subsequent generations were so observed. This is not the first
study to observe such change which usually drops out after a generation or
two.

"Was Lamarck genetics correct?"

No, his claim was for the origin of new species. His idea was overtaken by
darwin.

"Are the obesity and autism epidemics the result of epigenetic"

The first likely the second has no research to support the claim.

Part of the obesity response seems to be a genetic response to large swings
in food supply. During good times fat stores build up while they are used
to get through the poor times. The epigenetic part comes in when the hard
times switches the store fat genes on. The change drops out in the next
generation or so if times improve.

WRONG on all counts, of course. :)

It is NOT me talking, but the lead author himself, David Crews. Five
generations to date for animals, and 200 genrations for plants with no
drop off.

Again, all you have to do is listen to the entire interviews.
Premiere researcher Michael Skinner, also, has a lot say.

Morons like you are just A-holes. :)

The abstract you provided said 3 only. I did not listen to the links.
Plants seem hardly relevant to mammals.

Do tell us, in how many animal species do the epigenetic on and off states
persist?

I pay a great deal of attention to what the key researchers have to
say about their own research study. Only a SCIENCE MORON, like
yourself, would be arrogant to say otherwise.

I gladly defer to the experts in the field of epigenetics, and will
ignore the babblings of educated SCIENCE morons. :)

You are just an obsolete fossil. :)

"I pay a great deal of attention to what the key researchers have to say

The abstract you used said 3 only. Pay attention to what you post.

"I gladly defer to the experts in the field of epigenetics, and will ignore

Then it should be no problem to tell us how many switched on or off genes
persist for how many generations on average in how many species.

"You are just an obsolete fossil. :)"

Smile, I was reading about epigenetics and commenting on it for more then
10 years, since the beginning. You have only recently started to make
comment.

So we "fossles: have a thing or two to teach the new kids on the block.

Kindly, identified the epigenetic studies that you personally
published.

Until I get a list of studies that you were personally involved in, I
shall defer to the premier epigenetic researchers David Crews and
Michael Skinner.

Unlike you, both of them with their video interviews have put their
butts on the line. :)

"Kindly, identified the epigenetic studies that you personally published."

Read it again, no claim of original research on my part. I have followed
the literature closely because of my interest in evolutionary theory.

"Until I get a list of studies that you were personally involved in, I
shall defer to the premier epigenetic researchers David Crews and Michael
Skinner."

Nonsense, until we get your list showing that in but rare cases the effect
lasts but a few generations, you are blowing hot air.

Appeals to authority is among the least relevant kinds of evidence.

Now don't go trying that science stuff on us again.
