So say you have a clone or a secret identical twin because you know that a twin or clone is a genetically identical person to you, which is crazy! But it's true. Anyway, So you have this clone or twin or what have you, and your parents decide? that it's too much trouble to keep both of you And so they give your clone to a kind of sketchy traveling circus. Now I know your parents probably wouldn't actually do this, but just roll with me for a minute. So for the purposes of this example let's just say that you grew up living a normal suburban American life while your clone grew up with less stability and less access to nutritious food and less education. But more exercise and more access to sword swallowers and bearded ladies. And let's say you guys are 50 years old, whatever, you get together and have some lunch. So you sit in there across the table from your clone. What do you think you see? Well for starters, Clone probably has a tattoo on its face. And if Clone had stayed in the circus Clone probably, you know, professionally rides a unicycle over a tightrope, so Clone is probably in pretty good shape. But then again Clone probably smoked cigarettes and probably was malnourished as a child so might be slightly shorter than you. By the same token, let's say that you've been eating sonic tater tots five days a week since 1992 so you're looking a little bit tubby. Plus, you spent the last 20 years at a really stressful job that puts you at risk for all kinds of weird health complications. So at 50, you and Clone would probably look pretty different from one another. But it turns out you don't just look different. You actually have become different. Now, if some scientists looked at your genetic code they would say that your DNA was still exactly the same as that other person. That is to say, if your Genome is a paragraph all of the letters would be in the exact same [word] But on another level there would be a huge difference and if we extend this metaphor We can say that the letters are in the same order But the spaces in the punctuation are all in different places of course completely Potentially changing the message of that paragraph the study of this genetic punctuation that I'm talking about is called epigenetics which literally means Above genetics the epigenome doesn't change your DNA But it decides how much or whether some genes are expressed in different cells in your body? Epigenetics looks at what happens to your genes over the course of your life and whether those changes could be passed down to your children or even your grandchildren So here's the way epigenetics works you have billions of cells in your body and they each contain Your dna the same exact blueprint of your genetic code But just because they have the DNA it doesn't mean that they know what to do with it They need outside instruction from these little carbon and hydrogen Compounds called Methyl groups the way these Methyl groups control the genome is by binding [to] a gene and saying do not Express this Gene the Methyl groups bind Differently to your genome and a skin cell versus say a tongue cell or an eyeball cell and that is one of the ways that A cell knows that hey, I'm the skin cell or hey. I'm an eyeball cell hey I'm a muscle Cell. In addition to Methyl groups epigenetics is also controlled by Histones which are proteins that are basically the spools that DNA winds itself around histones can change how tightly or loosely? The DNA is wound around them if they're more loosely wound the genes can express more and if they're more tightly round than they express Less so whereas the Methyl groups are more like a switch the histones are more like a knob Every cell and your body has a distinct methylation and histone pattern and that is what gives Every cell its marching orders think of your genome the DNA is the actual hardware of the computer While the epigenome is more like the software which tells the hardware what to do the genome is what's going to be doing all the work but the epigenome is going to be telling it what to do so the hardware of your DNA is going to be the same throughout your Entire life, but these epigenetic tags do change throughout your life And they decide what genes get expressed or not. Now epigenetic information in a cell? Isn't permanent it can change throughout your life, and it can be hereditary And it can change over time especially when your body is going Through a lot of changes like say during puberty a bunch of Methyl groups kick in they're like okay So you guys over here? You're gonna have [to] start growing hair, and you guys over here I really need you [guys] to get behind giving this guy's some really horrible Acne or like when you get pregnant which hopefully I won't but when you do your epigenome has to be like [alright] guys [everything's] about to get a whole lot bigger in here And we're gonna have to pass something the size of like a miriam Webster's dictionary through that little pipe over there So let's get this thing done, but it's not just these dramatic times when the epigenome is changing It changes suddenly throughout our entire lives [and] it changes based on a lot of environmental factors like what we do what we eat What we smoke and how stressed out? We are in a daily basis scientists have found that things like a bad diet can actually lead to Methyl groups Binding to the wrong place and making mistakes and with those bad instructions cells become Abnormal and become a disease and then basically all hell breaks loose And you get cancer or something epigenetics is a very young science though. We've known about the epigenome since the 1970s It's only in the last 20 [years] that we've even known what Effect these epigenetic tags are having on our DNA and even after they got all that business straight Scientists still thought that all of our epigenetic tags were stripped off of our genome before they were passed on to our children So if you started smoking 10 packs a day when you were 10 years old that would certainly be a horrible health decision for you But you wouldn't necessarily be harming your unborn children in any measurable way however the thinking on [that] is changing pretty rapidly because it's true that a [lot] even most of the Epigenetic information from a parent is stripped off of the embryos genome in the first few days and fresh ones are created Specifically for this new person however some [of] these tags get stuck on the genome and are passed down from generation to generation [and] it just so happens that the more they study this the more it looks like bad Epigenetic information is being passed from generation to generation [and] this is a whole new way to think about how we pass information between generations your grandmother was making dietary decisions that affect you today as we experience all these new strange epidemics diabetes autoimmune disorders cancers that weren't appearing in Previous generations It's starting to look like these may be caused by epigenetic information passed down from our parents I know it's such an unbelievable Buzzkill there is no point in our lives when we can do anything without guilt anymore [the] discovery that the environmental Factors the parent experiences can be passed down from generation to generation was sparked in the 1980s and this happen when some scientists were looking at the birth and death records of some people who lived in [nineteenth-century] Sweden as is a weird place to find a genetic revolution, but there it is wasn't just any place in Sweden It was in Norrbotten. Which is the Northernmost County in Sweden Which is literally in the arctic circle and despite the fact that [norrbotten] was literally the worst place you could possibly choose to live in sweet there were some people living there in the 1800s and they were completely cut off from the rest of the world let me clarify these people were Isolated like if they didn't have a good crop year people died no, it wasn't ideal But you know they didn't ask me my opinion So I'm not giving it So anyway these people subsisted entirely on what they grew when the animals that they raised and like I said Sometimes they starved but sometimes they had huge bountiful years of plenty and what happened people totally went ape crackers I mean of course they did because they were so freakin hungry and then all of a [sudden] there was all this damn food everywhere anyway there was a public health specialist who was looking at the effects of the people who grew up in the really bad Starving periods of time versus the people who grew [up] in the eat all you can at the smorgasbord Years you might already be guessing what they found out people [who] went from relatively slim pickins to feed your face until you have to Barf and then do it all over again in a single season those people got an average of six years sooner than [they're] starved out Counterparts, and you know it sucks, so do their kids instead of their kids kids who epigenetics So of course now we all know and we're all going to stop doing unhealthy things starting today Unless the damage is already done the damage is almost certainly already done, but hey epigenetics brings good tidings along with bad ones for instance We now know that certain types of cancer are caused by misplaced epigenetic tags and scientists are now developing drugs that can Silence the bad genes that were supposed to be turned off in the first place additionally until recently we thought That genes were the end all and be all of who you got to be they were your blueprint and you couldn't escape them this Outlook is [not] just kind of depressing and also alludes to a yucky sort of social prejudice because when you look at Data without considering Social and epigenetic factors it might look like people with less money are less intelligent So just like 15 years ago there were scientists saying things in public mind you like some people just have good genes for Intelligence and it just so happens that the poor people don't all it's so sad too bad poor people But you have bad genes [well] turns out that that is not even a little bit true Not only are there a huge variety of social factors that affect How well people do on intelligence tests that a genetic trait is also, not just a product of genes it's also a product of environment any one person's genome was determined by any number of Is made by any number of their ancestors and right now you are making decisions that are going to affect [people] who are alive? long after you were Dead [no] pressure or anything and so I'm glad you've watched this because when you and your clone are in your 60s And you sit down have lunch, and he brings his son and his son has a tattoo on his face He did not inherit that from you. This is Hank Green from the Scishow. We hope you learned something.
As if there were any doubt.
Jordan Peterson , Stephan monelyx look at them when they speak about race and IQ
Of course. If something bothers about the alt-right is that they aren't anxious about discovering the truth about race and intelligence but about putting the white race back into a pedestal and throwing blacks under a bus.
I posted on lobsters sub Reddit they gave me pseudo science and downvotes me to hell

Is this Hank Green's brother? Hank Greene was one of the cowards who lied and said that "enforced monogamy is an anthropology concept". It's not. You'll never see it in any anthropology text book. You won't even see it asan anthropological concept in Google Scholar or any database. It's actually more likely to be mentioned in feminist publications of all places.
