Part 5 of 5 - The Ghost in your Genes - BBC Horizon

[moonmilk15]

holy shit (what I said to myself)

[ArnoldVinette]

Positve affects of environment would then play out with the birth of heavier babies that have been found to result in healthier humans over the course of their life time. There is another BBC Horizon program where doctors have correlated a babies weight at birth with healthier humans all around the world. Perhaps it is with the birth of heavier babies due to a better and healthier environment and diet that cancels out previous negative environmental shocks.

[ArnoldVinette]

I can see that human genes can be affected by environmental causes like famine and toxins in the environment. A woman is most affected as a baby in the womb when her eggs are being made. For a boy it is puberty when his sperm are being made. Humans born of these affected genes are affected in the next generation. Question? So when do positive environmental changes cancel out the negative effects of a previous generation famine or toxin? It can't be all bad or the human species would die out

[ArnoldVinette]

The graph in part 5 needs to be better explained. I've looked at it twice and its value is not apparent. It is almost as if the program does not want you to understand it. Another BBC Horizon program has looked at birth weight as an indicator for future health of individuals. Diabetes which was thought to be a disease of western diet was also found in Indian people. Birth weight was discovered to be the cause. Heavier babies = healthier humans throughout their life.

whole documentary is nothing but pseudo-science, i would have been better watching a christian young earth science video . even that shit makes more sense than this crapy documentary

[spacecourt]

Very awesome indeed, thank you!

[dinooshd]

awesome documentary and thankyou for uploading :)

Pembrey closes so well....

RHoffmnn: I have read literally DOZENS of studies on schizophrenia, as my father had it, and I did not want to pass it on to my own kids and the universal concencus is that only about 20% of the next generation gets it, and then only 5% the next generation, which goes to about 1% the generation after that.

This has profound implications both for the future and for present policy. Diseases such as diabetes, Alzheimer's, Autism and ASD, and some cancers are growing in prevalence. Environmental causes have been long suspected, including diet (diabetes), pesticides, toxic metals like lead&mercury and aluminum, and other industrial chemicals (pthalates, BPA, etc.) in our environment and consumer goods. Now it's clear they can affect not only us but our descendants.  Future health care costs: HIGH!

This is why they say your body is a temple

[TomDavid88]

What the video is NOT telling you is that these "switches", for lack of a better word, are NOT carried either 100% to the next generation NOR are they active for all time. ALL of our ancestors, for example, have undergone starvation, but we do not all now have that switch activated. The guys who discovered this just seem so happy because now it seems to justify all kinds of money being spent on "persecuted" groups from the past.

[ovejodog]

@TomDavid88 I agree with you to a large extent but I would offer a rebuttal. They did indeed say that these "switches" did not occur in 100% of the progeny (for example the disease formation from parental toxin exposure was only observed in 85% of the progeny). Also, they only claim to have seen the effects within 3 or 4 generations. Lastly, they stated repeatedly that none of them can fully describe the biological processes that are causing these results.

@ovejodog Most probably, these "switches" work to the same degree that, for example, genes for blindness, deafness, or schizophrenia do in that, while it occurs very often in the following generation, within three or four generations, the switch is hardly able to be observed at all. THAT is what should be made clear in this series, and is absolutely NOT.

[greeneyedgracie]

@TomDavid88 Yes but see, this video assume that you have a basic knowledge of genetics. Which anyone who has taken a highschool level biology class should. Shall we go back to punnett squares... Just because your mother was exposed to things, doesn't mean your father was. So if you carry your father's set of alleles, the environmental exposure your mother received may very likely not show up in you. That's just simple Mendelian genetics.

[TomDavid88]

@greeneyedgracie No, the video is pushing the view that there is such a thing a persecuted populations and so assumes that both parents have been subjected to negative environmental conditions whereas I'm saying that the genetic changes are functioning on a very different level than standard Mendelian genetics, as these thraits are very quickly bred out of any population and so generation after generation of social programs to help "disadvantaged" groups is unjustified.

Tom David

Minneapolis

[greeneyedgracie]

@TomDavid88 i don't think the video was made to sell social programs, i think that's you reading in between the lines. And it talks about the arctic circle town because it was something that allowed them to study the effects easily, not because that's how it works everywhere. Yes these traits can and are bred out over time, but they didn't even talk about social programs aside from the one the psychologist was a part of. and it wasn't "sold" to you as something we need.

[TomDavid88]

@greeneyedgracie As a graduate of an American public policy school, I can absolutely tell you that you are wrong. The liberal prosessors in these institutions gobble stuff like this up, as they have thus far been on the losing end of the nature/nurture debate. This study gives them at least SOME ammunition.

[HybridD91]

@TomDavid88 Can you give me the time on the video where it suggested the crap you're bringing up? I'll answer that, you can't. The only person suggesting that is you, so run along and watch something else.

[TomDavid88]

@HybridD91 I did not say that it is openly SAID in the video, but only implied. If people are at the mercy of environmental effects, and not personally responsible, then it follows, if you are a liberal at least, that there should be government intervention to assist people who are at a disadvantage through no fault of their own.

Tom David

[RHoffmnn]

@TomDavid88 A graduate of any school should understand logic and hopefully at least a modicum of biology. You clearly have some political axe to grind, but this science documentary is non-political. As others here have noted, you're inferring meaning and intentions that are simply not there. You seem to have an obsession with seeing some "liberal social agenda" in everything. It's not healthy. Deal with the facts and the science on their own level as it's presented.

[TomDavid88]

@RHoffmnn After seeing this, ANY of my liberal public policy professors would start arguing their thier social programs to help the "disadvantaged" actually even have science behind them. THAT is what I'm so concerned about. when, in fact, science is not behind them, except to the most limited extent, as ALL peoples are not currently suffering from these "switches" having been set off from previous generations environments.

Tom David

[RHoffmnn]

@TomDavid88 What is the scientific basis for your theory? It appears from your examples that you are confusing recessive genes (a part of classic genetics) with the fairly recently discovered epigenetics- i.e. the "switching" of genes due to environmental events. Furthermore, there is not to my knowledge any clear pattern (a disapearance of a disease condition within a few generations) such as you describe for such things as schizophrenia, for which heredity's role is still uncertain.

[TomDavid88]

@RHoffmnn If environmental impacts continued to effect genes over many generations, then EVERY population would be in some way handicapped, as EVERY group has faced devestating environmental circumstances at some time in the past. I'm saying that it clearly works works like the schizophrenic genes, which are very quickly weeded out of the gene pool. The offspring of schizophrenics have only about a 20% chance of passing these genes on, and only 5% the following generation.

Tom David

Mpls

[RHoffmnn]

@TomDavid88 You are still confusing the issues of epigenetics (the subject of this research) and classic genetic understandings re. recessive genes. As a result, you're also leaping to unfounded conclusions. There is not enough research to determine into how many generations gene switching might extend...the research was just for a few generations thus far. There is thus far no basis for making any definitive statement about how far down such effects are passed.

[TomDavid88]

@RHoffmnn No, I am not confusion the two issues. You simply have no understanding of current research on schizophrenia. It does NOT function merely according to dominant and recessive genes, but also stems from environmental factors.

Tom David

Minneapolis

[RHoffmnn]

@TomDavid88 You suggest that you know more about the topic of epigenetics than the scientists who have been doing the research; but from your remarks it's clear that you did not grasp even this simple documentary. Of course you're entitled to your paranoia about professors and liberals, etc.; even if it hinders your ability to learn. But I have no interest in arguing further. It was a good documentary that will doubtless be appreciated by many.

[TomDavid88]

@RHoffmnn No, but I DO know, being a graduate of a public policy institute here in America, how OUR "political scientists" will put this very limited study and idea to a much larger, and unjustified, use. The money given to EVERY "oppressed" group will be "justified" by this limited study.

Tom David

Minneapolis

[RHoffmnn]

@TomDavid88 As to the statement, "If environmental impacts continued to effect genes over many generations, then EVERY population would be in some way handicapped, as EVERY group has faced devestating environmental circumstances at some time in the past. " ,,,, This is such a sweeping generalization that I can't begin to address it in limited space. In addition to other logical fallacies, it's a classic reductio ad absurdum.

[TomDavid88]

@RHoffmnn No, it's the logical conclusion of what is being discussed, only transferred into the realm of public policy.

Tom David

Minneapolis

[RHoffmnn]

@TomDavid88 Thus far, it has been ONLY YOU who is "transferring this research into the realm of public policy". But now that you've opened that door, IMO at least, public policy SHOULD indeed be informed by science. No?

[TomDavid88]

@RHoffmnn Absolutely, most importantly the information we know about IQ differences and race.

[juliansarahconte1]

truly amazing!

[teainthesahara]

If I understood correctly, men only have to be careful of their genes at puberty and women during pregnancy. Or did I get that wrong?

[BandytaCzasu]

Great. I will never leave my house again. I could breath in some car fumes, this could ruin life of my grand-grand-grandchildren.

[TheAlexander356]

1 creationist disliked this.

[raiesh]

@metaball Exactly my thought too when I got to that part. It sounds a lot like Sigur Rós Ný Batteri

[Goatssoup]

thank you for posting this extremely interesting documentary! :)

[dsimmo989]

@AaronCee So one passage may state, coincidentally, something which has been observed in the modern age to be correct, and you're using this as evidence that the bible is factual? also u have just picked out a passage that states your god is a jealous god, the god of your religion is clearly a bellend. Think for your self do not allow your self to become a victim of the world wide terrorism that is religion!

[phabbiola]

poor rats =( .... but lovely documentary

[madmoody79]

fuck epigenetics , i wanna smoke n get wasted everyday , dis is not fair to the offspring .... y should they be punished for something they dont know shit abt ... wtf

[phabbiola]

@madmoody79 omg selfish trottel!

[madmoody79]

@phabbiola oh yeah, first become a chain smoker, than come across this epigenetics shit n than try to quit ....

oh n btw one more question, coz english aint my 1st language, so would u mind telling me wats a trottel ...

... fyi i am not a proper smoker, i smoke once in a while dats it ... so my children will be fine, hopefully ... lol

[watchamaculey]

@madmoody79 trottel means Idiot

[madmoody79]

@watchamaculey thanu , u took ur time though lol ... :)

[phabbiola]

@madmoody79 I just thought that after watching this it was very selfish to say what you say about wanting to smoke and get wasted. You do harm to your own body and will do harm to your future children...that is why I said selfish "trottel". Trottel is German...and it means idiot... Sorry I was mad. I take it back. Stop smoking please...

[madmoody79]

@phabbiola u sound like a girl lol , sorry no offense ... i dont know y but i will listen to u dude , i'll try quitting i promise coz u r right to some level .... thnx

[ferdiboy22]

OMFG I LOVE SCIENCE

[Gajoobles]

I wonder if the process can be reversed through the way of life of a person. Say someone is highly stressed due to his parents and such and manages to overcome it via certain things he does(such as but not limited to regular meditation and such)does this mean the gene is switched and this is also passed on?

[BrentAltonNally]

Fantastic information!

[tunnis7us]

I hope this give some push to the whole humanity to really start going off from every toxic imaginable. Otherwise it's useless knowledge if it comes the new a fact.

[kinnibangalore]

This sounds like Karma passed on from generations to generations.

[metaball]

@mattydigs: sounds like Sigur Ros to me, not sure of the track though.

[Arodblade]

Fap, fap.

[espnmarshall]

I wonder if this could tender an understanding of why cancer rates are up in certain areas and not in others.

[sm0kedopenrap]

vowwwwwww

[mattydigs]

Does anyone know what the music is at the 1 -3 minute mark? Would really like to know it sounds like some great semi-ambient stuff. Brian Eno, mebbe?

[micol018]

i wonder, maybe they will come up with something to reverse it

[AutumnKitten]

I've had a feeling that this was true ever since I was a little girl. This is also why I 'instinctively' do not want children with my husband, because he was exposed to radiation during the Army which I had a feeling effected his sperm. He also looks a lot like his grandfather who smoked and drank, which caused him to smoke and drink which again can and will change his genes even more. As for me, my grandma never smoked, never drank and I'm just like her in other things too.

[likeprestige]

@AutumnKitten Perhaps you should go through genetic testing to find the type of implications that the radiation exposure had on your husband DNA profile? If it had a negative result, perhaps see if this negative imprint can be manipulated. This manipulation is presupposes the radiation hypothesis and epigenetics in general. Good luck!

Lesson #1: Eat healthy, organic foods as much as possible, drink lots of water, exercise well

Lesson #2: If we are, then, predisposed to having a disease due to a factor our grandparents encountered, the only answer would be to consume something that will correct the problem - either turn the part of the gene on or off again.

The only thing at this time of which I am aware that has the potential to do this is certain glycoproteins.

The good news is that we can get them in concentrate.

[McHunt7]

Excellent documentary.

[Scherer321]

wow what a revolation. 

[RJL738]

This is import whatever is true about this because that means we should be more resposnable thank you for this.

[Felixinhk08]

it is a evolutionary discovery!
