探索世界奥秘之The Ghost In Your Genes(基因外遗传现象) Unit01

We are on the brink of uncovering a hidden world, a world that connects past and future generations in ways we never imagined possible.

What this means is an environmental exposure that your grandmother had could cause a disease in you even though you've never been exposed to the toxin. And you are gonna pass it onto your great-grand kids.

These extraordinary discoveries have the potential to affect every aspect of our lives.

It's not just the genes, but also the environment in the early life of your ancestors. It's not so much you're what you eat as something you are what your mother ate, and maybe you are what your grandmother ate. And if you take our data, you're what's stress your grandmother or grandfather had.

It would change the way we think about our relationship with every generation.

(it) Makes me feel closer to my children. What I experienced, in terms of environment will have some type of legacy in my children and my grandchildren.
The science of inheritance is being turned on its head.
We're changing the view of what inheritance is.

This small Swedish town may hold the evidence to launch a medical revolution. Överkalix lies huddled on the edge of the Arctic Circle. Inaccessible and remote, it was cut off from the rest of the world for most of its history. Marcus Pembrey has traveled here to meet his colleague, Olov Bygren. They believe that the story lying buried in these graveyards may hold the proof to their radical ideas.

Here we have at least 2 generations.
In the same grave.
In the same ...
This group of people could contribute to really a sea change in the way we think about inheritance.

They have come to this churchyard to find grandmothers and granddaughters, grandfathers and grandsons, connecting people who lived almost a hundred years apart in entirely new ways, uncovering links that confound scientific thinking.

Up to now, inheritance is just the genes, the DNA sequence. I suspect that we're gonna be able to demonstrate that the inheritance is more than that.

This is a grandson, as it were, in our study.
It is the culmination of more than twenty years' work and for the first time, Pembrey is confronting the magnitude of their discovery.
It really has come alive for me, coming here more than I had expected. It's really quite so, I'm, sure about it, wonderful.
