- Did you know that your environment and lived experiences can actually affect your DNA? Welcome to the world of epigenetics! In this fun episode of SciShow, 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. Let's go!

I actually think this is uplifting rather than depressing. If you choose to have offspring, you can make decisions now that give your descendants a potentially better life. Exercise regularly and eat right? Your kids might be more likely to do that, regardless of your original genetics.
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
Why am I not learning this in high school? This is the most interesting thing I've learned all week (but it's only Tuesday so)
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?
"Normally your parents wouldn't actually do that"
Tell it to my juggling and unicycle riding skills.
This was the best description of Epigenetics I've seen, thanks for making this.
What? You never saw Henrietta Lacks? ruclips.net/video/22lGbAVWhro/видео.htmlsi=Y-oQMg9OJ5kp0K94
This video explained epigenetics better to me than a lecturer who talked on it for an hour and that I pay 9 grand a year for. The Sci show is such an amazing resource, keep it up!
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
These older videos are just so more relaxed!
The beard
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.
Hank describing pregnancy was just beautiful :D
I love him 😆🥰
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.
Greatly appreciated.

Wow. Going to research this. But this feels like some really strong motivation to start changing my lifestyle. It won't just be superficial changes it can actually effect my genetic expression. Kind of horrible to think that parents actually have a genetic responsibility toward their children now. Glad I don't smoke or drink, but I am lazy and bad-ish diet (I hop between junk food and really green almost vegan meals).
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?
"I hope I don't get pregnant" hANK
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.
This is exciting. I discovered epigenetics few months ago and since then I can't stop thinking about it.
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.
maybe this is why things run in families, but no genetic links are found...
Yup like being very fat or muscular.
So, what you're saying is that I should get off of my ass, get a job, eat better, and actually contribute to society so that my grandchildren and great grandchildren will do the same? Sounds like a damn good idea.
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.
Your lectures are always GREAT! You make the dryest subjects interesting and, more to the point, very informative! Thank you!
"Here is where i keep my genetics"
*Opens a fridge stockpiled on junkfood and other shit*
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.
Also, THIS explains why GOTEN was so much stronger at a younger age than GOHAN! Goku was _Already_ a *Super Saiyan 2* when he was conceived!
***** 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
So, based on the Sweden study, it's possible that our obesity epidemic could be caused by the Great Depression. The people who lived through it would have had much more than they were used to when it was all over, so they ate more. And that got passed down to our parents and to us. I'm going with that. It's all my grandfather's fault!
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.
I live in norrbotten, sweden. It's not all bad you know, wish there'd be less mosquitoes though.
If living above the Arctic Circle doesn't kill them nothing will.
Though would be less mosquitoes 🦟 there
Damn my babies babies and their babies gonna be watching youtube
Last week I met a friend of mine's identical twin sister (it was weird at first) and I noticed one had slightly darker hair than the other and one was an inch and half taller. They had no idea why, and I said it probably had something to do with their diet and how they grew up, the shorter one as it turned out hated milk growing up, so never drank it, while the taller liked it just fine
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
Hugs, not drugs. Hugging your children, and cuddling your babies, and breast feeding, and having good nutrition while pregnant, treated well, not stressed out, creates better offsprings. Staying home if you don't have to work. Raise your own children.
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.
I've been subscribed for years, now going back to college, I find myself in 2022 being sent to a video here from a decade ago. Looks like I've been in the right place for a long time.
I love Hank so much. He has helped me through high school and now through college as a science major. Like for real, is there anything that this man does not know? Not to mention he "dumbs things down" in a way I can understand. So when I go back and do hard readings, I am actually able to know what they're talking about. Thank you Hank. Keep doing you buddy.
THANK YOU FOR THIS VIDEO! I've always loved genetics and biology, but I never knew how cells figured out What 'type' of cell they were... since after all, all cells (omitting gametes) have the same genomic makeup. Now I get that it's the Methyl groups and histones that do this!
Win over bad genes by practicing self control, trust me it is hard by worth it.
Young Hank at work there. You’ve had great videos for many years. Keep ‘em coming.
I was searching for a vid to explain epigenetic and I was really hoping hank or john had done a video on it. didn't realize scishow was hank! AWESOME
How could 100 people possibly dislike this video? It makes me wonder if they were just unable to comprehend what they were hearing, and therefore WERE UNABLE to enjoy it. Very interesting!
It's voted down because the dude is inconsistent and says a bunch of weird shit. Heavy editing. Etc.
new plan: use epigenetics to express some epicgenetics
@Mike Keller you are an icon
HA. HA. Funny. Amazing. Splendid. Spectacular. Fantastic. Marvelous.
Great video! I homeschool my children and we have been studying Epigenetics. Your video is the best one we have seen so far! It's so well made and easy to understand! Thank you for creating it!!:)
Dude let me tell that I am a tutor and my student didn't understand her teacher anything about epigenetics. And as soon as I explained it your way she was boomed how cool and more clearer it turn out to be
I love how he said "what we smoke" instead of 'if we smoke' lmfao
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
Well, I’m not having kids, so I’m going to have another stack of Oreos. Also thank you, this was a great explanation.
I enjoyed this more than I enjoy the more recent SciShow episodes.
i love how the graphics imply face tattoos are (epi)genetically inherited.
Yay! Thank you for this video. I was having a hard time understanding epigenetics from my psych 11 class' textbook and this video explained in a way that I feel confident about passing my quiz this week. Thanks again!
The way you tell things makes me love science more and more.Thanks :)
Well done. Its hard to find such an explicit definition of epigenetics. You are an excellent guide to greater undetstanding of this puzzling world!
You are incredible - and you save my life all the time with tough topics, wish more of my professors could be like you! Thank you!
Best description of labor ever!!
This is so interesting this has lead me to decide that I want to study this in depth in college.
I think this might have been the first video I ever saw from SciShow. Thanks guys!
Wow I had not heard about this before. Thank you for sharing. It actually sheds some light on questions that I have had.
I watched three videos and even slides from the professors, yet didn't understand this topic, but after sir Hank Green video I totally got it. He does it great even for whom with low ability to perceive. 5 stars
So what I got from this was that Lamarckism wasn't entirely wrong.
Yes! I like that too :D
just brilliant as always - everything i needed to know in a fun and informative video
Thank you so much for this, wow. I was struggling in class to relate this to real life and see how epigenetics was actually working and after watching this twice, I feel so much more understanding of it!
This would explain how evolution works, I've always wondered why if we are always passing on the exact same DNA (albeit spliced with someone else's to make a baby) then how can it ever create something new? It's just a mix of both parents building blocks... But if epigenomes are instruction tags that say how much we utilised specific genes through our life and how much we relied on creating more of specific cells then it means we can pass on traits. Not just our structure, but how it worked in it's environment, which enzymes we created most of because we had a weakness for chocolate, which cytokines we needed most of because we were susceptible to the Flu.
Scientists stated about 5 years ago that the biggest noticeable change in humans in generations is thumbs are now more dextrous than ever before due to remote controls and video games and the like, if that is true then wear and tear around our thumbs must be pretty high and our epigenome has taken notes and instructed that the next use of our DNA should contain stronger cells in the weakest areas. So we create a sprog with like 4.1% stronger thumbs :D
+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.
hey scishow! I think you should make subtitles in different languages, or let your community do it. Wanted to share this vid with a friend of mine who does not speak English, but there were no subtitles. To me, your channel is like a little youtube wikipedia )
I just adore your work!! thank you so so so much for giving us the opportunity to learn amazing stuff in an easy and simplified way, you rock 😅😅💜
Thank you Hank...and thank your team as well...this is quite eye opening.
I'm a big fan of Bruce Lipton. You give a clear and fun explanation of epigenetics. GREAT JOB!
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…
Your metabolism can actually change to adjust to diet and exercise habits over the course of about 6 months. The human body likes to stay where its at, so if you keep it in a perpetual state of six pack abs for long enough, it will adjust to maintain those 6 pack abs. You need to slack on your routine for 6 months to start losing sizeable gains.
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!
Okay, I know that I'm years later for this, but holy crap. This explains so much about my family.
This is a great video!!! You are so entertaining and provide so much information.
if your not having kids you don't need to feel guilty about Epigenetics
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.
You missed a good chance for a pun at 6:46
"isolated"
"ICE-olated"
The incarnation of boredom What killed the dinosaurs?
so informative, so easy to follow, and so delightful to learn. Thank You!
I heard a Swiss geneticist who went back into his own ancestry; which was in the Alps, and his ancestors also got snowed in every winter, sometimes starving a month or two before the spring thaw. The church kept good records. He discovered that the epigenetic benefits of starving for a couple of months during winter reduced all the chronic illnesses significantly, and extended life; a similar result discussed in this clip. In addition he mentioned that an ideal time for reaping the healthy benefits of a couple of months of starving was during adolescence, and an adolescent who starved would pass the benefits down for two generations.
He did not mention that starving is always bad for toddlers and babies. Too little food leads to brain damage when one is that young.
He did not mention that most (maybe all) hunting gathering cultures had puberty ceremonies in which adolescents and teens fasted for a month or two. Maybe those hunting gathering cultures, through trial and error, know some stuff we are ignorant about . . . . eh? (Trial and error; more than 200, 000 years of hunting gathering compared to 30, 000 years of agriculture and civilization.)
Now i have a reason to get healthier and never smoke or drink. YAY
as if you didnt before lmao
this has answered many questions I never knew I had😂😂
I hope enough people would be interested in having more videos on epigenetics! It is one of my favorite science topics !!!
I'm going to go back through all your videos just to make sure I give all of them a thumbs up.
my dad passed his tennis genes to me. ( he played at our and his former school in their championships. ) And im pretty good at it eventhough i rarely even play it.
My son goona be god tier video game player 🙄
watching this vid was actually assigned to me in bio class lol, best assignment ever..
Excellent work on describing epigenetics. I often send people who want to learn about the subject to this video. Well done.
Well done Sam.. Excellently mastered info presented.
Great video!
Stumbled upon this after watching a gaming channel with 2 presenters with incredibly awkward and cringy humor all the time (which they all have), and was amused and enjoyed the information. Like + sub.
I watched another video on this topic and almost everything went above my head
But this was so precise and easy to understand!
I know a small bit about epigenetics but I thought your explanation was amazing. I have a much better understanding now. :)
i should stop being depressed
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
You have saved so many people in school, we thank you.
So wierd seeing such an old episode!!
Great video, and very entertaining in addition to being informative. Thank you.
Haha, so thank you mom for being so healthy and taking care of yourself long before I was even born 😂🙌🏼🙌🏼🙌🏼 Whatever if this is true or not... she's a mom and she'll be glad to hear that she did something good. 😂😂 "Hey mom thanks for being healthy when you where young!" lol
i wish there was a playlist of 2012 scishow episodes because young hank is a dork and i love him
Excellent excellent video! Very inspirational! Thank you for making it!
This was really well done.
This was pretty obvious to me. I first learned about genetics in elementary school (I was interested in Jurassic Park) so when I read about it, I just assumed that your environment must effect your DNA, and you must be able to pass on the changed DNA to your kids, otherwise how do you even explain hereditary genes? Wouldn't we all basically have the same DNA, if our environment had no effect on it? So the first time I heard about hereditary changes caused by epigenetics I couldn't help but think "That's a breakthrough?"
It also explains how we can adjust to the constantly changing environment around us:)
Epigenetics (above genome) is really really cool science.
I ❤❤❤ Scishow and Hank Green you are awesome science presenter😘😘😘
Brilliant and classic: great job, Hank!
Very well done. A great explanation. Thank you.
I’m still trying to figure out if this is the same Hank that is on this channel now. His way of talking is so different and he looks pretty different too
Haha, the 2010s were a strange time hundreds of years ago. Like what were these jokes
so how did those methyl groups get there in the first place?
They are already present in the chemical compostion of a gene.
Smoking meth duh
hhahah look of the drug called methylphenidate
It would be from there addictive genes, that they must inherit. So this all falls on Adam and eve. Eve started it all and Adam had to follow. Lol
I love this guys personality. The Arctic Fox hunting in the Arctic after pointing out that the Swedish county of Norrbotten is in the Arctic was funny. Great upload my guy.
Thank you, this was excellent and so lucid!
Such a wonderful addition to the case for genetic determinism yet nurture is far more powerful for each and every person. Early Childhood Education should be taught in HS but we don't want people to have smarter and more adaptive children.
our system requires education turns our youth into cogs in a machine, workers with low creativity and imagination. it truly is a shame.
Maybe Lamarkian Evolution wasn't as far off as originally thought
+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!
This is the deepest most interesting thing i've ever watched...and i've watched A LOT of things.
Best video explanation of epigenetics. Thanks I had no idea and learned quite a lot.
I couldn't stop staring at his beard for the first minute or so lol..I was like woah Hank has a beard!! Lol
"In Norrbotten" he says, placing a sticker on Kiruna, Lappland. Norrbotten is on the coast, dang it. Unless he's talking about Norrbottens län which i think is the case.
I love you, Hank. Thank you for everything you do.
Really enjoyed this, Have you ever discussed the concept of biological aging?
In my grade there are these triplets. Two girls and a boy. The girls are identical and the boy is obviously fraternal. I swear, I can't tell the two girls apart. Is it rare to have fraternal/identical triplets? Just wondering
not really
Whoa you looked really good with a beard.
Thank you for sharing!!!! You are a great teacher!!!! It all makes sense now :)
Great video. Seems to emphasize the uncontrollable consequence of inherited genes, rather than the malleability of genes through lifestyle choice. If I'm not mistaken the switches of the methyl group and the knob of the histons is highly influenced by how you choose to live your life. So you, to a great extent, can "choose" which genes to exert. Take that pre-destiny
