Groundbreaking new science reveals that the harmful effects of exposure to synthetic chemicals are passed from generation to generation via “epigenetics,” causing measurable damage to future generations even if those offspring are never exposed to the original chemical. The phenomenon of “Epigenetic Transgenerational Inheritance” (ETI) has now been demonstrated in live animals, and if the implications of this research are fully understood, it would force human civilization to radically rethink its widespread use of synthetic chemicals in agriculture, medicine, food, construction materials, personal care products and elsewhere.
The research, led by Dr. David Crews (http://www.utexas.edu/research/crewslab) (and including colleagues Michael Skinner, Ross Gillette and others), is entitled, “Epigenetic transgenerational inheritance of altered stress responses” and is published in the journal PNAS (Proceedings of the National Academy of Sciences of the United States of America) (http://www.pnas.org/content/early/2012/05/15/1118514109.abstract).
The study, which was funded by a sub-group of the National Institutes of Health (http://NIEHS.NIH.gov), found that exposure to a common fungicide caused neurological and behavioral changes that were passed on to future generations of offspring, even when those offspring had no exposure to the original fungicide. Furthermore, the mechanism of “transgenerational inheritance” was epigenetic, meaning it was “above the genes.” It was not coded into the DNA of sperm and egg, in other words. Instead, the expression of the DNA was altered and inherited through some mechanism other than DNA.
As the abstract of the study sums it up:
“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.” (http://www.pnas.org/content/early/2012/05/15/1118514109.abstract)

Why chemicals threaten the future of the human species
This groundbreaking research offers a sobering revelation about the age of industrial chemicals through which we are all now living. This “age of chemicals” ramped up roughly around World War II (late 1930’s).
The conventional view of chemicals — the view advocated by the chemical industry, the cancer industry, the FDA, the EPA, etc. — is that the damaging effects of chemical exposure are NOT passed on to future generations (unless, of course, exposure happens during pregnancy). Chemicals are relatively safe, the regulators say, because the next generation is always born healthy and genetically intact.
But what this research by Dr. David Crews reveals is that chemical exposure accumulates and is inherited by offspring which then pass on the damaging effects of that exposure to their own offspring. This transgenerational “epigenetic” effect appears to go on indefinitely, forever altering the expressionof the genetic code.
