For 20 years I didn't know my birth father who left before I was born. Last year I finally found him and we were both surprised to find that we were similar in beliefs, personalities, even likes and dislikes even though my mother differed from us in many of these and hadn't told me much about him growing up
@@XOPOIIIO ffs thats not how inheritance works. you inherit exactly 50% of your genes form your father and 50% from your mother. becouse sperms and egs ahve bnoth exactly halfe the gene coutn humans have.
Does this mean that what I had for breakfast today will determine my children's destiny? I'm not sure, but I do know that epigenetic inheritance is equal parts controversial and interesting. Sure, it's got more questions than answers, but that just means we have a lot more to learn about it. Get to it, scientists of tomorrow!
My mom burnt almons her entire body with hot water when she was little. All that's left are some scars on her right arm. Later I was born with the exact same scars, but instead of those scars i have red birthmarks.
I have a very im-probable theory about love. Like you said in this video, the cells for a child are inside of the baby before it's even born. My theory is that when someone falls in love, maybe the person they fall in love with has a similar and/or same child cell and that's why we have different tastes. But then again, you can't sense/see the cell and a stranger that you think is beautiful won't have the same genes as you but like I said, it's im-probable. Please tell me if this theory may actually be correct or not.
For some reason I am very afraid of Eye Injuries. I've never had any experience like this, but I have a lot of fear and aversion to this type of wound. I feel anxious and nervous whenever I think about it. I can't process or imagine an Eye Wound, it's almost like a Phobia for me. My father and grandfather also had this fear, none of them had an injured eye. It's so strange.
It was eluded to, but how close of a tie between mother exposure during pregnancy and these effects is there? It would seem the only interesting effects would be those seen outside of that, and it wasn't clear evidence of such has been provided.
so would it be accurate to assume that because women are born with all the eggs we will ever have, those eggs will carry the tags from the mother of the woman? this would imply that a woman's epigenetics, which change as the woman grows and matures, could only actually have an effect on her future grandchildren? or is it more complex than that?
2:00 I was just thinking that. It's so weird when we disprove something, only to later figure out that the ridiculous idea actually had some merit. But not to the extreme of extending your neck to make your child's neck longer... Right? Oh man, what if it turned out he was right about that as well? Or at least somewhat?
How about the traits can be passed on thru 1-2 generations, but not more, and after a few more generations it just happens that the traits recur by coincidence? Also i would like to add that a human as a machine, is not perfect. We are flawed.
I think it can differ for some people, here's an example, I'm 5'11, I'm taller than my mom and dad. also may I add that I am taller than both my grandparents from each side respectively. according to my dad, my great great grandpa was 6'2 so it depends
Has there ever been any evidence for epigenetic traits showing up more than two generations down the line? AFAIK the methylation of the stem cells in the ovaries of female embryos are _really_ deleted, so there is no way to have an effect of more than two generations along the maternal line and one generation along the paternal line.
+Penny Lane I have yet to see an animal study (and I've looked pretty hard) that goes past F3 for females and F2 for males. It's like the researchers just stop them there, or if they continue then they don't report it. That's what makes me skeptical of this in humans. But it's definitely been shown in plants across multiple generations. Time will tell?
I read of a study of pregnant women during WW2 (I forgot which country) - their children had "starvation syndrome" and were therefore, obese. This pattern was continued for 5 generations. Reminds me of this verse: Deuteronomy 5:9 "...visiting the guilt of parents on children, to the third and fourth generation ..."

+woody500z If intelligence is something that can be measured, it isn't all that impressive. Its not as much that intelligence in something inherited, but more like specific talents in something that makes someone geared to be more successful in some field intellectual can be inherited. Beyond that there isn't a great way to show how intelligence could be something inherited, other than showing that a mutation that causes some mental disability can be passed down, but that is probably not what you meant when you said intelligence being inherited. There are some studies that show how intelligence is something that can be inherited genetically through a culmination effect of many genes, but that isn't really all that straight forward and leaves many things unanswered in my opinion. But studies that do address this question involves stuff in things like Alzheimer's and Parkinson's disorder (both neurological disorders), which can negatively affect neurons causing memory problems and stuff. Alzheimer's and Parkinson's disorder are things that can actually be diagnosed or are easier to measure than something like intelligence, more importantly they also know about some of the genes that may cause these disorders which makes it possible to better understand how things involving functions of the brain can be inherited.
Ok, I have a theory... We all see color differently, I see a "brown" sky, and u see a "green" sky, but since we were little, we identify that color as blue though. My brown color is ur green color, but we all identify that color as blue. We can't really prove this because we can't look through someone else's eyes Am I crazy or not? Comment below if this makes sense (btw I'm just a high schooler)
Millions of other people have thought of this. No, you're definitely not crazy, and all people may process some light waves in ways others cannot not imagine, if this hypothesis is true.
+_NoName_ You can tell what range of colors humans will see when presented with such colors by just studying how the eyeball / brain interaction works. I would think.
Some of the numbers here are utter nonsense. Take, for instance, +32 years life expectancy difference, or 6 ft of DNA. It ruins the rest of it for me, in a way.
And what is your basis for declaring those numbers nonsense? Just bcz "it doesn't sound right" to your brain? The guy in the video has done plenty of research and studied peer-reviewed papers to say what he's saying, and check the description for his source. What research have you done? Your intuition tells you it's nonsense so it's nonsense? No, sir.
that parent child grandchild image just blew my mind. The eggs that will one day become my future kids were with me when I was an embryo, so all three generations are present in at least a partial form.
i whouldnt say that its more like: "when my grandmother was cooking my mother i was inside her too" since you are a collection of your mom cells that where in there
Insofar as you may have inherited the genetic changes they brought on themselves. But that also means that its up to you to stay skinny and change those genetic markers for the next generation.
How do they breed dogs that love to fetch a ball? Retrievers ? DNA can alter not just looks and health, but behaviors...? I think this is how migration and other animal behaviors are passed on.
That part where they say we were once inside our maternal grandmas. Really shows how how we treat people might have consequences, not only now but in generations in the future... even amongst kids we might never get a chance to meet. So interesting.
What is sad from my P.O.V. is that everyday any of us venture from the safety of our house into public we witness how many humans treat others with so much disdaining entitlement. That's not a route to knowing peace. It's so heartbreaking.
I read about this somewhere else too. The evidence for epigenetics is strong. And it's scary. Staying healthy for men during conception has never been thought of as a problem but it could be that a man or woman smoking during conception could be as harmful as women smoking during pregnancy. Imagine that
Meanwhile all I inherited was mental illness, anger issues and toxicity :( You have no idea how hard it is to stop myself from being a toxic a** hole. Thanks a lot, dad! :(
Epigenetics sounds like a mix of Lamarck and Darwin, I think they both had some truth to it, we may be still missing some key information on how fully evolution work. Genetics, Adaptation, and Natural Selection.
Jalil Popalzai Yeah, i think it puts up the question if a person who wants a child has a duty for it, years before it is born, and therefore has to live really healthy and stuff like that.
So, huh, my mother having felt sick from the smell of fish in the early stages of her pregnancy might have activated gene flags in my developing embryo resulting in my lifelong fish intolerance? My body treats it as if it were poison (i.e.: immediate expulsion, no questions asked), so that could be due to misled exposure by proxy which resulted into my genes activating to identify it as poison?
I see you have a reference to Jablonka's work. It's well worth reading her book 'Evolution in Four Dimensions', which explores the interesting interactions and interrelations between genetic, epigenetic, behavioral and symbolic inheritance systems.
My whole family on my father's side has been a very skinny child and then a more fatter adult, all the way back to my great great grandfather, which basically proves to me that he is completely right, I just hope that I don't become fat like my fat-ass dad.
Great video, Joe, made me think of Agrobacterium and the way they can share plasmids between individuals through bacterial conjugation. Could humans take this biological mechanism and make it somewhat of a human conjugation or is that just a cool plot for a science fiction movie? It would render hereditary traits obsolete, as we could just take some DNA from a fellow human with the desired trait, make a copy using enzymes and then implement it into our own code.
Yes, epigenetic inheritance is a real phenomenon. It refers to the transmission of information from one generation to the next that affects traits, but doesn't involve changes to the underlying DNA sequence. Instead, epigenetic inheritance is mediated through chemical modifications to DNA and histones, which can influence gene expression. Researchers have observed epigenetic changes in various organisms, including plants, animals, and humans. These changes can be influenced by environmental factors such as stress, diet, and toxins, and they can sometimes be passed on to offspring. While the extent and significance of epigenetic inheritance are still being studied, evidence suggests that it plays a role in development, adaptation, and even certain diseases. However, it's important to note that epigenetic changes are usually reversible and often do not persist for many generations compared to traditional genetic inheritance.
+Daniel Silva Expose to the smell followed by something like an electrical shock. Rinse and repeat until fear happens without the shock. It's called "Conditioning" in case you want to look it up.
Could we spread our trauma and fears through our children either via our own raising methods via our thoughts/actions/lessons? Or does it also lurk deep inside our DNA?
Does this explain, sort of, why Americans of African decent have higher risks of blood pressure? Or is that all across the African genome regardless of origin?
Why did the mice being fed a high fat diet get fat? Because mice are herbivores and aren't evolved to eat a high fat diet, unlike hunans who just get full quickly and require less food when fed a high fat diet>(omnivores)

I think Epigenetics certainly is true because i have an unprecedented fear of my wife/girlfriend dieing (My great grandfather married twice both his wifes died)
It kinda sounds like when the bible says "You will have to pay for the sins of your parents" (im paraphrasing). Not trying to argue the existence of god or anything. Im just sayin that if you understand that phrase with the knowledge of epigenetics make more sense. Maybe if we look the bible with scientific eyes we can actually learn something
+needpit1 That is just worthless though, over interpreting, and over thinking what was meant to be a threat, to make it seem true, based on what we know now. Almost everything in the bible was meant to be taken 100% as is, literally.
Please allow me to clarify for you in context. Ezekiel 18:19-23 Amplified Bible (AMP) says: The son will not bear the punishment for the sin of the father, nor will the father bear the punishment for the sin of the son; the righteousness of the righteous shall be on himself, and the wickedness of the wicked shall be on himself. Godspeed friend❤
cant it be like an encoded message in your DNA slightly pulling it in a certain evolutionary path faster then normal cause if i was that mouse and that fruity smell means its dangerous i would like my kid to know to stay away but i cannt sense i would most likely run the other way cause of my life experience telling me to stay away. so i some how send a message to my chield thought my DNA. but if he or future generations keep experiencing that conditioning wont it be similar to a catalyst to get a sharper sense of smell and detect it from a longer distance? i think its similar to the Sound video that make us more scare to certain sounds.but this is just my uneducated option
About the famine and heart attacks. seems like you should talk about what they did eat during the famine instead of what they didn't, as what they didn't wouldn't have had much of an effect on their dna... just sayin.
Exogenisis is the idea that life was brought on Earth by an external source (such as an asteroid or a spaceship). Like, maybe Earth wasn't home to bacteria and simple cells until an asteroid brought them here. That's the idea behind it.

Eating fat does not make you fat. If you want to make your mice fat then feed them sugar. When farmers want to fatten up their livestock they feed them corn (carbs) not fat. Read The Big Fat Surprise by Nina Teicholz to learn more.
+Kathryn Mercier Eating carbs makes you hungry so you eat more. Eating fat makes you feel stuffed so you don't eat as much. So in a round about way it matters what you eat.
+Superior Knives Yeah, but that doesn't require epigenetics. Normal genetics could explain that too, unless the friend's dad has been skinny at some point of his life.
+Tuupertunut It doesn't even need genetics to explain it most of the time. If you grow up eating the same way your parents did, you're likely to end up as fat as they are.
+Everything Explained Neither! It is possible for two science channels to both cover the same topic without one copying the other. More perspectives, especially on a controversial topic like epigenetic inheritance, is a good thing. Anyway, I'm friends with the MinuteEarth team and I love their video on the topic. We've been discussing our different opinions on this subject for months.
The high fat diet wouldn't be the thing causing that kind of epigenetic result. The fact that the mother mouse was obese would be the reason. You would see the same result (likely worse) if it was a high sugar-low fat diet.
Except that he said it was a high fat diet that lead to them being fat. Eating more calories lead to them being fat, and it was the fact that they were fat (not dietary fat) which caused the epigenetic results.

+Daniel Silva Expose to the smell followed by something like an electrical shock. Rinse and repeat until fear happens without the shock.
It's called "Conditioning" in case you want to look it up.
You're either lucky or you're not.
Could we spread our trauma and fears through our children either via our own raising methods via our thoughts/actions/lessons? Or does it also lurk deep inside our DNA?

Does this explain, sort of, why Americans of African decent have higher risks of blood pressure? Or is that all across the African genome regardless of origin?
Why did the mice being fed a high fat diet get fat? Because mice are herbivores and aren't evolved to eat a high fat diet, unlike hunans who just get full quickly and require less food when fed a high fat diet>(omnivores)

He developed a theory one day
If one has simply resolved
To act more evolved
Then one's children will be born that way
I think Epigenetics certainly is true because i have an unprecedented fear of my wife/girlfriend dieing (My great grandfather married twice both his wifes died)
It kinda sounds like when the bible says "You will have to pay for the sins of your parents" (im paraphrasing). Not trying to argue the existence of god or anything. Im just sayin that if you understand that phrase with the knowledge of epigenetics make more sense. Maybe if we look the bible with scientific eyes we can actually learn something
+needpit1 That is just worthless though, over interpreting, and over thinking what was meant to be a threat, to make it seem true, based on what we know now. Almost everything in the bible was meant to be taken 100% as is, literally.
Please allow me to clarify for you in context.
Ezekiel 18:19-23 Amplified Bible (AMP) says:
The son will not bear the punishment for the sin of the father, nor will the father bear the punishment for the sin of the son; the righteousness of the righteous shall be on himself, and the wickedness of the wicked shall be on himself.
Godspeed friend❤
cant it be like an encoded message in your DNA slightly pulling it in a certain evolutionary path faster then normal cause if i was that mouse and that fruity smell means its dangerous i would like my kid to know to stay away but i cannt sense i would most likely run the other way cause of my life experience telling me to stay away. so i some how send a message to my chield thought my DNA. but if he or future generations keep experiencing that conditioning wont it be similar to a catalyst to get a sharper sense of smell and detect it from a longer distance? i think its similar to the Sound video that make us more scare to certain sounds.but this is just my uneducated option
About the famine and heart attacks. seems like you should talk about what they did eat during the famine instead of what they didn't, as what they didn't wouldn't have had much of an effect on their dna... just sayin.
Can someone explain what "Exogenesis" is then? PLEASE. I looked up the meaning, but I am still confused.
Exogenisis is the idea that life was brought on Earth by an external source (such as an asteroid or a spaceship).
Like, maybe Earth wasn't home to bacteria and simple cells until an asteroid brought them here.
That's the idea behind it.
Oh, ok, cool. Thanks!
My dad got into a car accident before I was born that dented his skull. I was born with the exact same dent in the exact same spot. I always wondered if it was somehow passed on to me genetically.
+Wade Wilson That's pushing it. You did not inherit that from your dad.
It's Okay To Be Smart Probably not, but there are studies out there that say physical trauma may alter your DNA. If not it's a strange coincidence.
thegamingbroz 11 Not if I was born that way. It isn't a injury.
DO IT!!! YOU CAN DO THIS!!! NO MATTER WHAT PEOPLE SAY, YOU CAN, TRUST ME! SO MANY PEOPLE HAVE THOUGHT THEY COULDN'T BUT THEY DID! YOU CAN BE THE NEXT PERSON WHO SUCCEEDS!
+ChiChaChiHa Okey, I'll do it, I'll join the hot dog contest!
Fat
And so many of those people failed, wasting their life on an unachievable dream.
your advice just got me rejected
jk, I didn't do anything
+ChiChaChiHa Thank you...now, I'm in prision
I swear when I was in kindergarten I used to punish my left hand for doing tasks. I'd like to think it was because some poor ancestor of mine was getting a ruler across the knuckles by some crazy nun.
I'm early. Let me think of a joke.

+Turtle its weird that a trump supporter ended up in educational video.
+Samir Shrestha ROASTED
Ethan Shaw Meh im not laughing. Now hillary lying constantly and people still believing what she says now that is hilarious.
Hm... Why the fact that the mother that could past blood with the epigenetic of their life would be considered a really early exposure, and not proof of epigenetic?
*Note: A very confusing question that I am perfectly sure no one will answer me.
If moths are attracted to light...Why don't moths fly towards the sun? And to anyone who says "Well duh, their is no air up there, idiot" Please think about, do they really know what air is or that they need it?
To put it in simple terms... We don't actually know.
So I have siblings that I know are there but don't and never will exist? -goes to cry in a corner because parents don't want to have another kid- at least I have my cats and fish TuT
Fear of the dark, disgust.....
what if our chemical flags evolve to be quantum chemical flags?
Eating fat does not make you fat. If you want to make your mice fat then feed them sugar. When farmers want to fatten up their livestock they feed them corn (carbs) not fat. Read The Big Fat Surprise by Nina Teicholz to learn more.
+Keira Churchill He said, at 1:28, that mice fed high fat diets get fat, unsurprisingly. It is something that many people believe but is incorrect.
+Kathryn Mercier Eating carbs makes you hungry so you eat more. Eating fat makes you feel stuffed so you don't eat as much. So in a round about way it matters what you eat.
Assassin's Creed confirmed.
I like your hair style:)
How has natural selection disproved the concept that acquired traits could be passed on?
They say sexual orientation is linked to epigenetics. How so ?
While not entirely, it is effected by testosterone and estrogen levels. Perhaps that has something to do with it?
so... the Animus is real?
So my friend is fat bc his dad is hmm now it all makes sense
Yes. If your parent are fat, you have high probability being fat also. Source: my family.
+Superior Knives Yeah, but that doesn't require epigenetics. Normal genetics could explain that too, unless the friend's dad has been skinny at some point of his life.
+Tuupertunut It doesn't even need genetics to explain it most of the time. If you grow up eating the same way your parents did, you're likely to end up as fat as they are.
+Superior Knives that is how it works if your genes influence your fatness, which it does for some people more than others
Out of all the genetic code I only count one cat. This isn't Internet worthy :)
Did you get this from minuteearth... or the other way around?
+Everything Explained Neither! It is possible for two science channels to both cover the same topic without one copying the other. More perspectives, especially on a controversial topic like epigenetic inheritance, is a good thing.
Anyway, I'm friends with the MinuteEarth team and I love their video on the topic. We've been discussing our different opinions on this subject for months.
Sooooooo, Lamarck was a BIT right?
We share 45% DNA with plants, 50% with fungi, 60% with all multicellular animals and 70% with all vertebrates.
Ok, say " Scarlet" then Joe's first and last name.
Ha you said " Scarlet Johansson"!!!
Lysenko was right, cope mendeloids
Partially. You know, being a fanatical neo-lamarkist or neo-darwinist is equally cringe and unproductive.
The high fat diet wouldn't be the thing causing that kind of epigenetic result. The fact that the mother mouse was obese would be the reason.
You would see the same result (likely worse) if it was a high sugar-low fat diet.
That's what he said.
Except that he said it was a high fat diet that lead to them being fat. Eating more calories lead to them being fat, and it was the fact that they were fat (not dietary fat) which caused the epigenetic results.
Yeah, he pretty much said that in a slightly different way.
+cubs0110 But the specific type of diet is relevant, I guess that's why it's mentioned.
Sven I'm saying that it's not, apart from being high in calories.
I'm Batman
You stand there and tell us. But I want to see the research.
So...nobody knows....
