The most damaging effects of environmental contamination are indeed hereditary, but they are NOT genetic mutations.
Oh, okay. Now I see what you meant. You mean adaptation in that regard.
The good news is, if we clean up the environment, our species is not stuck with permanent genetic mutations in the human gene pool. Which is why I said, "…(epigenetic effects) can be "tweaked" and modified to return to a healthful state by changing the causal environment."
The butterfly study showed that each succeeding generation of mutations in butterflies was magnified (due to exposure to Fuku Radioactivity). The first generation slightly, the second more and by the third the butterflies were mutant creatures, barely recognizable.
Only the first generation was directly exposed, the succeeding generations weren't. So cleaning up the environment doesn't "help".
You are trying to reduce us to so many bits of DNA that can be tweaked and retweaked with the perfect formula.
How our microbes make us who we are
Rob Knight is a pioneer in studying human microbes, the community of tiny single-cell organisms living inside our bodies that have a huge — and largely unexplored — role in our health. “The three pounds of microbes that you carry around with you might be more important than every single gene you carry around in your genome,” he says. Find out why.
