The wonderful part of this is that when we bring change and healing in our lives, we are supporting future (and some say past too) generations.

so the experiment with the fruit-flies passing thru glass labyrinth, and selectively breeding only say the flies that chose left-most branches of the labyrinth were actually passed by epigenetic labels?

I do like the Simplicity of the presentation, although when compared to information from other sources it seems like there's some potentially inaccurate information slipped into this video. I would definitely recommend looking deeper into epigenetics and root causes from other sources.

Epigenetics works. Except you have to be given the image in your brain. It works only when you fully “imagine” “believe” see it in your brain and you will begin to mold to it. Trust me. I did it. But I was given chemo. Then before everything started changing I was given an image during a dream. A smiling in the mirror new me. Then months later he came. The genes turned on. I watched it happen under extreme circumstances.

Epigenetics I think helps the individual/offspring too, adapting the genetic code to work more optimally with the environment. At least we read some examples something like that in my ap bio class in high school. Or maybe I’m remembering it wrong but it makes sense to me. Sounds like an advanced evolutionary adaptation if u ask me... Make a video on horizontal gene transfer!

The world already reach its overpopulation limit back in October 31 2011 at 7 billion. It selfish to have children since that number will be 10 billion by 2020 and 50 billion by 2050. I am okay with being selfless and not reproductive to save on resources for the planet and to reduce poverty for the benefit of the whole human race. You can't afford to think only about yourself anymore and more people should willingly give up having children o that we don't cause suffering to our species until we get ourselves under control

Epigenetics: the study that everything that grows has humble beginnings. Your life is made of the decisions you make; what you've yet to do or doing right now determine your success, however success isn't guaranteed.

8:30, yes it's incredibly bigoted and ridiculous to suspect that more intelligent people might somehow be more successful at acquiring and keeping resources and therefore produce stratification along lines of intelligence. But intelligence testing is valid, IQ is vastly more influenced by genes than anything else, and genes are obviously heritable so...? The truth is bigoted I guess?

*Epigenetics* has enormous potential in completely preventing genetic diseases (including some cancers) from passing through to the next generation, making it incredibly important to every one of the billions of people alive today. There's also the ethically murkier use of Epigenetics to "improve" the human species (according to concepts discussed by Transhumanists). Ideas like: extending lifespan, delaying senescence, even augmenting intellect, which (with technologies like CRISPR Cas9) may actually be achieveable during current human lifetimes. ~ ~ ~ On a related note, one of the greatest evolutionary biologists that predated Darwin was *Jean-Baptiste Pierre Antoine de Monet, Chevalier de Lamarck* . Given the new evidence that we're learning about Epigenetics, I think that you should definitely devote a future episode (or even series) on his theories, commonly called *Lamarkism* , as many biologists are revisiting aspects of his ideas that were thought to have been made obsolete by Darwin's theory of evolution through natural selection.

i think whole memories of someone's life is contained in our DNA, couple with that of a shared experience of the the other side of our our self, thus we have biological symmetry.

Nobody, but nobody seem to expalin this: If a gene is turned off, what the hell is expressed in it's place? If i have, let's say, a mutated finger, and i cover that gene up, there would be no finger expressed? What would it be insead of that mutation? It can't be nothing, please, explain this to me, i would apreciate it very much!

Hello! Our last conversation left me think about this: if a gene is bad, in the perspective of epigenetics, what exactly makes the helicase go and read the "backup" copy in another part of the genome? How does it know that a speciffic gene is the right one if it's not in the range? Thank you!

So essentially, what we thought was simply observing our parents making poor choices that determines bad behavior, is actually a Darwinian type of genetic passing from parent to child? But it can change based on a child’s own personal life experiences...

You seem to have forgotten that it's the person who's alive that has majority control over the expression of their epigenetic info, not the person that's dead. You're leaving out a huge part of the field and leading these people to believe they're still victims, when in reality you couldn't be any further from the truth. It's people's environment/their perceptions that affect their epigenetic expression predominately, not their parents'/ancestor's experiences, those snippets of information serve as a baseline of operation, not as the end-all-be-all. You're treating epigenetics like they're genetics AKA inherited "actions and reactions" from one's parents, and that's completely wrong. Do yourself a favor and stop spreading misinformation.

A better metaphor than equating the epigenome to hardware would be that the epigenome is the operating system and the genome is the uploaded software.

Genetics? No, I'm way epigenetics.
Jamie Mattinson (5 месяцев назад)
The sad reality of epigenetics is that we are completely, now, genetically inferior to the superhumans that once lived in Africa, specifically prior to agriculture. We'll never, without the help of nanotechnology and stuff, be as athletic and homeostatic as they probably were (aside from maybe disease factors, but not chronic or stress related disease). We've blown it, at least in the 'developed world'. The happy reality, though, is that we can understand epigenetics and use it to give future generations and perhaps ourselves this generation a better shot at homeostasis, health and happiness by altering our behaviours and environment to make ourselves as happy, healthy and homeostatic as possible, and try to work back up to a genetically better-off human race.

Glad I found this, Apabetalone is an epigenetic drug that is in a phase III trial right now, FDA and EMA approved....the trial is attempting to prove that Apabetalone, aka RVX-208, that it can substantially reduce the risk of a Major Adverse Cardiac Event like stroke or heart attack, in patients with Diabetes Mellitus, and there's a couple subset populations for Chronic Kidney Disease and Alzheimers. Exciting stuff.....using epigenetics to regulate dna from disease to non-diseased states....hope it works, results due out at the end of the year.

Epigenetics does not bypass the hereditarian theory of intelligence. On the contrary, epigenetics entrenches hereditarian theory. That's because epigenetics is 100% all about genetics. The most you can do with epigenetic ideas is hope that the genetic expressions for stupidity are temporary.

Great video, very interesting. Just to add, I worked in 2 traveling circuses over 6 years. The people there generally work very hard and have to be very fit. They also eat well, and definitely don't have facial tattoos. I found it a very positive and creative environment. I get the point you were making, but the stereotype of circus people isn't true on the whole. I only mention this because they do suffer prejudice based on these stereotypes.
