Today's Environment Influences Behavior Generations Later: Chemical Exposure Raises Descendants' Sen
Exposure Raises Descendants' Sensitivity to Stress
We are now in the third human generation since the start of the chemical revolution, since humans have been exposed to these kinds of toxins," says Crews. "This is the animal model of that."
"The ancestral exposure of your great grandmother alters your brain development to then respond to stress differently," says Skinner. "We did not know a stress response could be programmed by your ancestors' environmental exposures."
The researchers had already shown exposure to vinclozolin can effect subsequent generations by affecting how genes are turned on and off, a process called epigenetics. In that case, the epigenetic transgenerational inheritance altered how rats choose mates.
The new research deepens their study of the epigenetics of the brain and behavior, dealing for the first time with real-life challenges like stress. It also takes a rare systems biology approach, looking at the brain from the molecular level to the physiological level to behavior.

Could this be the smoking ADD,ADHD,AUTISM,depression etc gun?
As another said, we wont eat any but PERFECT fruit/veggies. Before we can change our exposures, we must educate our population to accept imperfect grown foods. Lowering the price might be a start, as they would be throwing less away. It would allow us to have cheaper organic foods.
I buy most foods imperfect, and cheaper. Those I cook for complain a bit. But, I am an accomplished chef, and they get over it. Time for a campaign, sorta like the campaign that told us dandelions are pretty.
PS, reducing work pollution and exposures is also important. I have fought bitterly with employers that demanded you expose yourself.
