step by step, we are finding ways to look deep into nature. in this particular chapter, 'written record' would show its true benefits more than a hundred years past.

how this will relate to GMO crops?? What genetic info are we consuming? Human genes are inserted to bovine to produce human milk. Will that now operate a switch in the humans who drink that milk? Has to, because the mice born from a tampered with adult carried to next generation. wow! crazy!

Moral of this story: If you're not reproducing normally. nature wants you dead.

DNA is packaged into a chromosome.

When DNA is tightly packaged into a chromosome, transcription proteins cant access the DNA.

When parts of the DNA are loosely packaged the transcription proteins can access the DNA to make RNA.

So this video is talking about how the packaging of DNA can be inherited and change the way an organism looks or functions. The changes in packaging can be a result of environmental factors.

Watch "On epigenetics (part I)" - its helpful

Okay, I have a question: The women near the end talks about how the experience of the holocaust effect the grandchildren and children of the survivors, but what were those symptoms? If it's just that they worry (no pun intended, please understand) couldn't that be due more to sociological/lifestyle reason then genetics?

@bpine20: Oh, sorry, just watched Part 4.

@CooCurrent: Thank you for posting these videos!

What is the mechanism whereby these life-experiences are transmitted to the egg cells? I am under stress; stress is caused by heightened or reduced levels of some hormone; the egg cells then pick up on this? How do the hell do the chromosomal genes in the egg cells know which experiences are relevant to their on-off states?

anyone ever read Ender's Game? this is like the idea behind the telepathic community of aliens that are the antagonists in that novel. Or more precisely, they start as t

These seem somewhat plausable, this is a very well made documentary.
