(6,437 posts)Great that everyone talked, but scientific rigor means accepting having to prove hypotheses. I'm done harping on it, so no comments on DAN! or Herbert.
I'm on a cell, so I can't really post links, but there is some really interesting research being done on the chemical revolution and physiological changes generations later. Essentially researchers injected a generation of rats with a mold and found that two generations later descendents reacted to stress situations differently than rats that had no ancestral contact.
The research is in its infancy, but if this physiological changes can also be shown to carry over in humans, well, we might be able to explain a lot of things. Essentially exposure from things like mustards in the wars, dyes in factories, etc were so pervasive we would be seeing pretty massive effects today. If I remember, I'll post the study here or in GD tonight when I get out of work.
