Hank & his clone Circus Hank explain the power of epigenetics, which studies the factors that determine how much or whether some genes are expressed in your body.

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.
I had (possibly) a great great grandfather who liked tobogganing and did it professionally. I grew up not knowing about him and I loved watching tobogganing on the TV. I think I inherited his wish for the adrenaline rush. Anyway, garlic, turmeric and apple cider vinegar, that's all you need, don;t smoke, don;t drink, exercise, walk, oxygen (according to Paul Davies Physics of Cancer) cancer hates oxygen. oh and watch some Brett Rogers videos. You're welcome. Good vid.
Identical twins have many interesting. You would be surprised. If you separated the twins for 50 years you might find they have similar passwords and hobbies and look very similar. They think very similarly.
there is no law that says we have to have two different color genes we can fix/cure inherited traits Stop the hate science only cares about inherited traits, the cure exist dominant and recessive traits, Rise Against said it was "the good left undone" there is a lot of good in everyone, so don't be blinded by there color just hang out and love one another
I love these videos. I'm a substance abuse counselor and psychotherapist - I show your videos all the time to my client groups to explain complex issues linked to mental health and substance use issues.
Thank you for making these videos.
I wonder after half a lifetime with a genetic disorder where my insulin receptors do not function. If my insulin receptors were suddenly turned on what would happen to me? They kept telling me in 5 years did be able to fix it well I think we're at a point now where it may be able to be fixed but my original team doesn't want anything to do with me because I mentioned money once! They made a lot of money off me and all I asked for was my travel expenses from Maine to Boston and back and my doctor up here at the time and said they would give me that but they never did. It doesn't matter now that was in the 90s and they should be speaking to me now or at least my Dr.
This lends credence to the idea that people are largely a product of their environment.
It also kind of has some horrible implications for people that grow up in abusive situations. And all the children growing up in war zones. What kind of epigenetic changes would occur in populations who have multiple generations suffering through similarly extreme situations of stress?
Epigenetics is nonsense. And a quick glimpse to most comments here shows how missleading and dangerous could be. What this funny guy and his clone are telling here is plainly wrong. Let me explain it. First, he skips to tell us how those epigenetic tags (methylation, histone acetylation, etc,..) go specifically to a particular gene that, according to him, will cause obesity, cancer, and other illnesses. Who and how 'tells' which gene has to be methylated or its histones acetylated? Is it God? I believe it is not. Second, to methylate a particular string of DNA bases you need specific enzymes called methyltransferases of which there are hundred different in each cell. How methyltransferases know which stretch of DNA has to be methylated? The true answer, and not the science circus that the funny guy and his clone performs, is that to do the job, a specific methyltransferase is recruited by specific transcription factors already bound to that particular gene. Therefore, all this fuss about epigenetics is mere gene regulation retold in a way both wrong and obscure. Moreover, the swedish example is not true as it is not the often cited epigenetic effects of the Dutch Hunger of 1944. So, please, stop talking nonsense, give clear examples, and do not confuse people. Thanks.
Thanks for the video! One would think this is a discovery of the 20th century however the Bible describes this beyond any doubt in Exodus 34:7 "Keeping mercy for thousands, forgiving iniquity and transgression and sin, and that will by no means clear the guilty; visiting the iniquity of the fathers upon the children, and upon the children's children, unto the third and to the fourth generation."
Genes still regulate the upper and lower limit of possible expressions. Even with the best environment if your genes predispose you to an IQ of 100 it might become 110 or something, never 200. A little different with malnutrition, but even then you would observe a difference between someone who is predisposed for higher intelligence as opposed to someome with lower predisposition.
But reprogramming of the DNA occurs after sperm and egg fuses, which causes only 1% of the epigenome of parents to be passed down right? That's such a small percentage of a parent's epigenentic taggings, is it really going to have such a drastic effect.
I love studying the genetics/biology of twins! I just did a video on my channel that answers commonly asked questions like whether identical/fraternal twins run in families, can they skip a generation, etc.
What is the difference between epigenetics and behavioral genetics? It seems behavioral genetics works with epigenetic mechanisms or what other mechanisms does behavioral genetics exhibit other than the ones in epigenetics?
So basically, epigenetics is the study of heritable change in the gene expression(active or non active). The gene expression is controlled by social/environmental facts, this is why your 50 year old twin has the same genetic code but not the same genetic expression.
welp time to continue to avoid cigarettes considering both my grandmothers as well as my father and his father smoked... seriously I'm very predisposed to it, and not so much to alcohol since my parents and grandparents never cared to drink
So, am I supposed to thumb-up all these videos because I believe science is under promoted in modern society, or should I only thumb-up the good SciShow videos? Some are definitely better.
And the political ones are totally terrible. (I even boycotted the channel for a while because of Hank's political ignorance.)
I don't know if the Sweden food intake example was a good study for epigenetics because there have been studies showing that fewer calories can actually cause organisms to live longer. This has been shown in monkeys for instance. Anyone have other examples?
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
