The 8 proteins are histones and form a protein complex known as a histone octamer, which is spool shaped (marshmallows were used in the demonstration). The 8 proteins in the histone octamer are actually 2 copies of 4 proteins, H2A, H2B, H3 and H4. DNA wraps around the histone octamer known as a nucleosome and they form chains like beads on a string making up chromatin. A nucleosome can be defined as a small length of DNA wrapped around eight histone proteins. The key difference between chromatin and nucleosome is that chromatin is a whole structure of complex DNA and proteins while nucleosome is a basic unit of chromatin. The beads on a string make up something called euchromatin or open chromatin that is enriched in genes and active under transcription (transfer of genetic instructions) which is why it is so important in epigenetics and changes in the phenotype (physical traits- e.g. appearance).

Her explanation about stress and childhood experiences is interesting. I was very fortunate because I had a pretty stable, happy childhood with a protective father who thought I was a piece of gold and a loving mother who was a great nurturer. Even though I was overweight and constantly bullied, I retained my happiness and confidence that has allowed me to be successful in my career and personal life. I am married to a great person, but have noticed that he is usually depressed and insecure. His sister has finally admitted that out of 6 siblings, he was given the least amount of attention and praise and was often criticized. This was needed information for me as his spouse because I can now understand why he rather that I remain overweight. When I lost most of my weight, my husband would exhibit jealousy and insecurity. He would retreat into his den, and not talk to me. Now that I have lost my mobility, my husband seems happy which I find hurtful, but with theory, I have learned that he feels empowered because he feels no one will find me attractive and he can now be the only person I can depend

so the dna is still the same, just the little "jelly" dots that attach to the dna that a person might develop while interacting with his environment? But what's the mechanism behind the epigenetic changes (my guess it's still the DNA that gives instructions to the protein to make the epigenetic changes)...I mean could epigenetic changes lead to the eventual creation of a new species? Thinking more ahead, how much can we augment our body through tweaking the expression of various genes, like would we be able to grow a new arm through epigenetics, or is that sort of mutation still dependent on the manipulation of DNA? You say that the little "jelly" dots, sorry I forget the exact term you used for those molecules, attach to the genes and affect their individual expression, but how many genes do we have, what are each gene's functionalities, how does each gene interact with each other, and what explains the difference between us and a chimp or a bird or something? God damn it get more research done lady! My back is hurting from watching all these Royal Institute videos laying on my bed at 1AM in California, and I also don't have a car to go to work tomorrow morning, and I think it'd be really nice if DNA technology can allow me to grow a pair of wings! (though the image might be a bit grotesque) so I can fly around to work and buy groceries or something...

In all biology textbooks, Galapagos finches are mentioned as a prime example of evolution. However, a relatively recent study conducted by Peter and Rose-Marie Grant documents that the changes in beak size and shape of these birds that Darwin observed do not take millions of years, but change continuously at a rapid rate of as little as two years and that the changes are reversible. It is very likely that it is epigenetic adaptation, not evolution in the Darwinian sense. This certainly also applies in many other cases where adaptation is interpreted as macroevolution today. The theory of evolution must and will be rewritten.

There's one thing I am confused about. So if the histones are wrapped around our genes, and say you become a smoker (but no one in your family tree extending hundreds of years smoked) and the chemical tag is added to the histones to make that gene become 'expressed', does that mean that the 'smoker gene' is predetermined? In other words, will I have a 'smoking gene' by default that is turned off, but will only be turned on if I smoke?

Very nice video and a good, yet brief presentation. I wonder what sense is actually used in the female to identify that the male was traumatized and causes the offspring to be runts. Of course I do not expect some active cognitive process of the female. But I would run the experiment over and over again with a blind, then a deaf, then an asomnic (is that word even correct?), etc. female mice, also combinations of these senses. Being unscientific now, I imagine that smell could be the important sense here, but that is pure speculation and this approach (guessing) is not scientific at all. This talk made me think. I was born premature and would not survive without modern medicine (in the 1980s). My parents told me how hard it was for them to see this tiny helpless being enclosed in an incubator, they could not hold it in their arms, cuddle with it. Now I hear in this video that mice who were less loved tend to be more depressed. So naturally I wonder if there is any connection to myself now, as in my very first days of life I was inside an artificial environment, connected to hoses (my lungs were not fully developed at that time). I tended to be "cloudy" more than my brother and peers during childhood and even now many people tell me that I am a pessimist and sometimes that I am depressed (and frankly I feel that too, but do not recognize it as a serious problem yet). This thoughts could well be just confirmation bias of a speculation. Nevertheless, it makes me think broader now. Conclusions? None. I am not an expert in this at all and actually cannot do anything about it, so why bother about some hastened amateur conclusion? It does not make life easier. But as we say in my native language, the bug is successfully planted in my head. Meaning that this idea (or meme if you want) which came out of pure speculation is in my memory and I will have to live with it from now on. I can just hope to forget it, or at least not be reminded too often about that. I hate my brain, it makes me remember unpleasant and/or embarrassing memories all the time.

I too wondered the same about the mice, would love a link to that experiment and more. I think depression has more to do with early childhood and less to do with the infant years......my sister is prone to depression and a few of my friends, and after years of observing and analyzing them and why and when they get depressed it usually has to a lot to do with being or feeling inadequate or unaccomplished in life.....my sister grew up with higher expectations from my parents than I did and I see that with my friends as well....in turn I don't let failures get me down probably because my folks were more relaxed about my shortcomings and so I take life in strides and it us what it is. When I talked with my sister about this at first she denied it, but over the years she has finally accepted this and started changing her own expectations for herself and worked on not caring how others view her or her accomplishments....what a difference it has made in her getting depressed....she is more happy and enjoying life. Hope that helps you with your depressive states.
