I definitely learned this in high school! By reading my textbook. I'm certain that some biology textbooks will include this in their contents -- I think in some cases students don't realize how interesting their textbooks really are

Omg! It is Tuesday. 😂😂😂

@jrowarrior Are you okay?

In my textbook of my last year of highs cool there was a short paragraph about epigenetics. The teacher didn't explain anything about it and I didn't understand it from the textbook so I came to this video. So even if it's in your textbook some teachers might not even address it.

You out of high school yet?

It's Phantom Strida

Hey it's Phantom Strider! I love your videos on cartoons and your Top 10s are especially fun!

Or you could just adopt a kid, there is a lot of kids out there seeking for a better life, that could be a solution

holy cow its you! I also agree that epigenetics can lead to future generations having better health and welbeing

You're absolutely right read Deuteronomy chapter 30:19

I am going to quote another comment... DANK GREEN

I like when cussing Hank gets put out into the world.

Yeah, I've seen older videos where people are actually asking if he's stoned, in the comments. No, just a bit more low-key, low-budget, slightly less `professional' but just as interesting. I guess his stage presence evolved over time too.

Everything older is more relaxed.

I know that you wrote this comment 7 years ago but I’m hoping that you listened to your lectures, (then googled it once you got home!) & did really well AND learnt lots of things about genetics!! 🥰 I thought that females were born with their eggs already ‘complete’. How can a mothers life choices effect their dna? Is it only mens life choices that effect the dna of their sperm?

I hate university for this reason lololol

What? You never saw Henrietta Lacks? kzfaq.info/get/bejne/aJicesVyu73MoqM.htmlsi=Y-oQMg9OJ5kp0K94

I love him 😆🥰

Ha ha ha. Well put. LMAO!

@Jack Smith Incorrectly assumed causal claim over here.

except it's probably that your ancestors did the same thing that got you on your ass in the first place :D

Well, maybe. Getting a desk job and playing videogames all day is the same thing to your body. Getting a hard job is terrible for your body, because you don't have time to fully regenerate between shifts. But our society is kind of streamlining the middle grounds out.

Yea man we gotta do the right thing in Gods eyes, a lots at stake

Said responsibility was never in question people who were physically active early in life and had kids had noticeably fitter and attractive offspring.

my dad started smoking when he was 15. I also started around that age. is it too late?

@@robertimmanuel577 First, it's never too late to make changes. Second, I really doubt there are epigenetic tags related to cigarettes. I would suggest trying vaping. It may not be as good as quitting, but every single cigarette smoker I have known has successfully quit with vaping.

So? How's your life now?

john warter that's what they all say

@Rock Stone Well, given that Hank is male, him getting pregnant would be a little weird. ;)

​@@emilymarthasorensen1516 Yeah. It might mean he got some human version of that crab-infecting parasite that makes both female and male hosts biological become pseudo-pregnant. This comment brought inpired by a different sci show episode.

***** Science, my friend....science ;-)

I think you mean GOTEN. Gotenks SS3 is still weaker than Ultimate Gohan.

Sigh... duly noted, Yuji. A bit irrelevant, since we all knew what I meant in terms of Goku's sons, but you are right; I stand corrected. I'd need to see some proof to see that the fusion of Goten and Trunks is somehow weaker than Gohan's ultimate form.

Ultimate Gohan was beating Super Buu with Gotenks infused.

The problem with Gotenks, if I remember correctly, wasn't a LACK of power, though, it was that he *1]* Tended to make attacks that were more *visually impressive* than they were effective *2]* He doesn't properly USE his strength in a battle. In actuality, this is a lot different then saying he's "physically weaker" than Gohan, as its really more a matter of application and skill. If you look at it fairly, Gohan has been trained and in life-or-death battle situations from the time he was a baby; first time he used his power when his stroller got away from Goku, he literally burst through a thick tree.. As such, he tended to be a more *effective* fighter. Remember, Goten grew up without Goku's serious training, OR a mega-level threat he had to battle, like Cell or the androids. But the mere fact that Goten could actually attain SSL1 without trying at 8 years old speaks to how powerful he was naturally; Gohan had to endure a year of training in the hyperbolic time chamber and lose his friendly Android before he went SS L 2

There's this thing called the Dutch Hunger Winter, where one winter in Holland tons of people went malnourished suddenly when Germans cut of the supply lines. Children that were conceived during this time are more likely to suffer from obesity and cardiovascular disease than the rest of the population. They also have less methylation of certain genes than their brothers and sisters not subjected to famine during gestation. (source: www.news.leiden.edu/news/dutch-hunger-winter.html) The theory being that the mothers were suddenly really hungry and this coded their children to think that they were being brought into a world where food was scarce and that they needed to conserve it, affecting their metabolisms and accounting for higher rates of obesity and cardiovascular disease. As you say the same might be found in North America, where people are genetically predisposed to hoard food against the famine that never comes. There's a full scientific paper about this from the Proceedings of the National Academy of Science of the United States of America (PNAS) here: www.pnas.org/content/107/39/16757.full

I agree with you all the way up to when you blamed your grandfather... Now that we are conscious of the fact we can alter our genes to eradicate this from ourselves and ultimately our children.

Not so fast - it's more specific than that. The Great Depreesion wouln't have done and in fact did not do what the DHW did. In Holland those affected were specifically seen in people who were in the 3rd trimester of gestation during the starvation. Other stages didn't produce the same results. And.... a couple other things too - here's a lecture that will explain it - the bit you'll want starts at 54:12

I know this is eight years ago but thank you for taking the time to write that

Also maternal stress and if mother Ever smoked.

And on a side note, i am so glad i decided not to procreate, not that i would even get an opportunity or anything like that.

I'm not quite on that level, but I decided can relate, found out at about the same time, and have been thinking a lot about it.

Yup like being very fat or muscular.

Ditto....Amen

First years last forever.....

But VACCINATE them

@@dallassmith230 love this comment omg. I know it's a serious problem but oh my did this comment make me laugh. I'm vaccinated btw and I will vaccinate my children once they're born. I just can't imagine how some parents are ignorant enough to not vaccinate their children. It kind of scares me knowing people actually believe not vaccinating their children will do their offspring any good.

Now consider that those same anti vaccination people can vote own business and can be in positions of power.

If living above the Arctic Circle doesn't kill them nothing will.

Though would be less mosquitoes 🦟 there

highly doubtful of the milk factor , since lactose intolerance might play a major part...my guess would be gender differences, and how they grew up; amounts of sun, exercise, and , yes, diet, stress.....stress can cause grey/white hair growth

the hair thing I wasn't saying the milk thing that was more the height thing and there is no gender difference, don't you know what identical twins are?

Kate It IS possible to have male - female identical twins...extremely rare though....the embryo can have an extra x chromosome and split into xx and then xy....i thought this was the case here.....anyhow it doesn' t matter, you see, because the twin sister likes to wear high heels....didn't you know that?? I already knew that!

i immediately thought of the elric brothers

23cokebottles They aren't twins though

+Rob Fraser variation comes from sexual reproduction/gene mixing and mutations. This is more like icing on the cake.

+Rob Fraser Not sure if epigenetics would be enough to explain evolution. At least, not as much as plain ol' genetics. While there's a lot to be said for our non-coding DNA that contains remnants of unused parts and proteins, the bottom line is that those are remnants of things that *used* to be, which can't turn into new things just by being switched on or off (or anywhere in between). Mutations had to happen to generate new combinations, especially if early life didn't have any "unused" information to periodically switch on or off. Mutations actually happen all the time in our everyday lives, but they're usually unnoticeable and inconsequential, and when they're not, natural body functions that "clean up" malformed cells usually get rid of them before they do anything (or, more important, make more mutated cells). Given such a frequency of mutation, it's not hard to believe that a large time scale would give rise to a lot of significant mutations slipping through the cracks and eventually causing change. DNA is frequently copied imperfectly, and it still has a heavier swing on big-picture organism function than the epigenome, as far as we currently understand their roles.

It seems like epigenetics makes it possible for humans to quickly adapt to changes in our environment. Evolution is a slower process and on a different level.

Weed is worse for you than tabacco

@@EPlTHANY Almost certain it's the other way around. While marijuana isn't perfect, it actually has medical uses unlike tobacco

@@masario5832 Wrong, tobacco massively lowers your chance of getting Alzheimer's. Also weed has 4 times more tar in it than tobacco smoke

@@EPlTHANY Alright then, I stand corrected

@Mike Keller you are an icon

HA. HA. Funny. Amazing. Splendid. Spectacular. Fantastic. Marvelous.

It's voted down because the dude is inconsistent and says a bunch of weird shit. Heavy editing. Etc.

Yes! I like that too :D

yes that's exactly what I read about the 'agouti mice'

+Ben Hinman You give me hope. Recon the physical changes giving the six pack prompt a change in methylation patterns? Would you be able to give me a source on your comment?

+Iulia Faur Oh i'm not saying its easy getting there. I've never had a full washboard six pack, but i've had some pretty nice abs for a while and its been a long time since i worked out and i have been seriously slacking off and not losing my body shape. I used to be super skinny in college and as a kid i was super fat and couldn't lose weight. So some of it is down to personal experiences but i really started to learn about how to control my metabolism after taking a nutrition class in high school and the teacher was on the california board of dieticians and she broke down some of the different epigenetic stuff, and cell cycles and stuff. Supposedly every 7 years your body replaces every cell in your body, thats not true, its actually different intervals for different parts (your brain cells will last for life but your stomach cells get replaced daily). But she explained it like your body was a rubber band that would snap back to where it was at and it likes to stay there, but if you hold that for 6 months your body and metabolist will adjust and come to expect that.

Which will explain why I've managed to maintain my 6pack since middle school... was always skinny, could never gain weight... but i also ended up going on work out binges every few months... I once was able to get up to an 8pack in highschool due to wrestling... but I've come back down to a six after the year ended and I stopped working out so hard. Interesting stuff, our body. SO awesome and thanks for the info!

as if you didnt before lmao

IW Nunn Bruce Lipton seems like a nut to me.

We've all been called nuts at one point or other

IW Nunn I haven't. Bruce on the other hand has abandoned all science a long time ago.

That you know about. Bruce is apparently on a path that works for him. I thank him for putting out there the things that I can use in my life and wish him well as I do you.

IW Nunn"Works for him" doesn't mean he is doing science and doesn't mean he isn't crazy as shit. His website mentions his “recent reports” dated 1972 to 2001…

Dip Schillips Knowing your genes are going to suck enough to willingly remove them from the gene pool... Darwin would be so proud.

Dip Schillips Well if you don't become a healthy good parent, then who will produce intelligent and untraumatized children? It certainly won't be the single mothers living off of welfare financed at your expense.

Metal Fuel and Fire Maybe they just don't like kids.

+AgentWashingtub Well the reason that you were born in the first place is somebody "liked kids" enough to be willing to contribute the inordinate amount of resources and attention needed to raise a child. Don't you think it's the right thing for a capable competent and empathetic person to pass on that gift? The world is sorely lacking in good parenting and awash in damaged people falling on ducks and ending up destroying the empathy of the next generation.

Metal Fuel and Fire But the word is also edging to wards over population and I see no reason to contribute to that.

raptorkil It's hard to tell how serious (or not) people are being here in the comments, but having suffered from severe depression myself, I tend to err on the side of serious. So I highly recommend a book called "Feeling Good". I can't remember the authors name right now, but it's easy to find and inexpensive. It's based on Cognitive Behavioral Therapy (CBT). It wasn't the whole puzzle for me, but it was very helpful.

raptorkil just don't breed.. :/

so here we have a helpfull comment and a not helpful comment which would you choose?

Check out why you lack 90 essential minerals for life. This is crap

I already have more control over anxiety and depression than both of my parents did. There is hope

not exactly, your epigenetics is forever changing

dojo west. tv And most is not passed onto the kids. It’s a pretty minimal difference in the end.

+John Smith The mechanism of Lamark was wrong, most odds. But the end outcome of his idea may still be true

+John Smith Just what I was thinking. Pretty ironic. Lamarck was still pretty far off though, but at least epigenetics lends some evidence that he was at least a tiny bit right in really obscure, indirect ways.

Jack Smith no one here said that. lamarckian evolution is just like evolution tends to make huge leaps, due to disaster or whatevs, instead of in small, gradual increments. if i slaughtered that explanation, anyone who can do better feel free to correct me

Jack Smith ok. i was trying to explain something to you that i was under the impression you didn't understand, not because i feel like i'm any kind of expert, but because it seemed like no one else here bothered to try. if you already know, and better than i do, then good. have a nice day

Oh snap!

It also explains how we can adjust to the constantly changing environment around us:)

our system requires education turns our youth into cogs in a machine, workers with low creativity and imagination. it truly is a shame.
