Scientists now know that our DNA is being altered all the time by environment, lifestyle and traumatic events.
Genetic faults caused by trauma, poor lifestyle or environmental stress can be passed down to future generations, scientists at the University of Cambridge have discovered.
Previously large studies have shown that devastating events such as famine can scar future generations, making them more prone to obesity and diabetes.
However it is the first time that the biological mechanism for the effect has been seen.
Although the same genes are passed down through generations, scientists now know that our DNA is being altered all the time by environment, lifestyle and traumatic events. It is thought that these changes drive disease, premature ageing and early death.
However it was believed that these faults could not be passed on to future generations, with the slate essentially being wiped clean.
But now scientists at University of Cambridge have found that in some areas of DNA, including those linked to mental illness and obesity, some of the faults remain.
In fact, around five per cent of our genetic code carries traces of past events, meaning that trauma, poor diet or poor lifestyle choices may by leaving a devastating legacy for children and grandchildren....

Lysenko rides again!
(Which doesn’t mean the studies are inaccurate.)
Damn you, grandpa!
Numbers 14:18, The LORD is longsuffering, and of great mercy, forgiving iniquity and transgression, and by no means clearing the guilty, visiting the iniquity of the fathers upon the children unto the third and fourth generation.
Looks like Lamarck was at least partially right.
Intriguing.
Reminds me of another study a while back; I’ll link if I turn it up again.
I thought we got rid of this acquired traits inheritence crap back with Lamarck.
“Settled Science,” no doubt. There’s a consensus, don’t you know?

Epi-gene. Old news

Two possibilities.
Studies are inaccurate.
Studies are accurate and show that acquired traits may to some extent be inheritable.
It is what it is.

This has been hypothesized by serious researchers in modern times for some time, it is not breaking news. Nor is it Lysenkoism.
So Danny, BJ Clinton’s only real biological child (of which we know), could have inherited a propensity for rape, in addition to a bent Johnson?
The proto-giraffe streeeetched his neck, and the next generation was born with longer necks ...
We were taught this when I was in elementary school in the 1970s.
Righto.
But some people seem to be fixated on the notion that genetic information is simply passed down from generation to generation without change except by random mutation.
That’s always seemed a little simplistic to me. I’ve recently been running across research, for instance, that viruses may be able to modify the DNA of the host organism. Which opens up some interesting possibilities for the mechanism of evolution.
Sounds rather Jungian.
The sins of the father. Seven generations?
My EXACT first thought.
