Epigenetics: Nature vs nurture

[@hagenfarrell]

That last sentence is pure gold. Our choices can make real differences in how we develop as human beings. People really can change, even down to a biological level, and over time its as if they have become completely new people. That can go either way, good or bad. Depending on your choices.

[@darkultra]

You can't help who you are, but you can decide what you become then?

@@miranx5735 Bi basically means two, so two-directional aka. works both ways/directions

[@beelight1407]

Well, I guess what we decide also comes from nurture which is our lifestyle+environment and experience and I think that eventually links to our genotypic expression. Development happens in presence of environment so I think we can't separate who we are to the choices we make. and I believe that 'we can decide what we become' is more of a motivational philosophical quote and it certainly helps as again (environment+lifestyle). But hey I can be wrong its just my opinion.

As truthful as this is, I think we need to highlight the importance of neuroplasticity and understanding the reality that if we did grow up with "low-licking rat mothers," or, an environment lacking nurture and rather exposing neglect, we can become are of this and change the course of our future so it is a positive one. So even if we experienced trauma and neglect while young, we still have power to create new neural pathways in the brain even as adults and heal our trauma and create good lives for ourselves. The issue with this concept is there are countless amounts of children who are experiencing neglect, abuse, and trauma, and for them to see this video as an adult is probably going to be unsettling, especially if they do not have a degree, etc. It can make them feel hopeless. So we have to then look at the lives of highly successful people, who did experience extreme neglect and trauma, and what makes them different. It is also important to understand what we can do to support children who are growing up in a household of neglect, to ensure that they can change their own lives and create something better for themselves.

So, it's saying that genetics can be physically altered by the environment. But that environment is dependent on the genetics before it, i.e. the high licking mother had to have the exact same environment, therefore, genetics are dependent on the environment and vice versa. Anybody realise that? Also, does anybody realise that most important things come in two's? Like night and day, good and bad, men and women? None can exist without the other.

As I interpret it, it seems that the way a mother(and father) behaves with the offspring genetically changes the behaviour of the offspring - in other words- nurture

[@myroseaccount]

Which shows the importance of environment and nuture.

[@abram730]

The offspring of low licking rat mothers have high rates of hypertension(high blood pressure), heart disease, diabetes, cancer, and are very aggressive, violent and are antisocial. Think of how much that costs human society. The poor in the US mistreat their offspring and brag about it. Look at the medical, prison, and social costs.

[@MaratibAliShad]

From this video - it is clearly impression that nurturing is more important which can impact on genes. But being success Coach I do believe that third thing of power of choices which comes from your conscience, emotions, body and mental intelligence, make your destiny.

[@johnisaacfelipe6357]

Maratib Ali Shad but isn't your concsience, emotions, body, and mental intelligences are all just products of genetics

[@MaratibAliShad]

John Isaac Felipe all higher forms of conscience, body, mind and emotions are not products of the genes.

[@johnisaacfelipe6357]

well they are, everything about yourself is produced by your genes, you likes, dislikes, your habits, and the areas of comfortability are all results of your genes expressing itself. it can only be suppressed or enhanced by the environment you are in. its silly to think that evolution has contributed heavily in the polymorphism of our species in all manners of physical attributes except the brain as if the brain isn't a physical thing. especially when the brain is the most important organ and thus recieve the most fine tuning (which is supported by the dominance in the number of transferable alleles that designates the creation of the mind compared to any part of the body). if you were born a psychopath, you are a psychopath, if you were born a savant, you are a savant, if you were born as a genius, then you are a genius, all the environment does to you is that it determines to what extent is your psychological and mental alleles are expressed.

[@MaratibAliShad]

if this is true what you say than power of chice is also determinded by Genes? Great decisions made by man in history were result of only genes not spiriutal connections to make power of choice?

[@johnisaacfelipe6357]

Maratib Ali Shad most likely. I'm not saying that each of your decision was fated to happen due to your genetics, but your decisions are actually heavily influenced by it.

[@GamerzShit]

So what is the conclusion? If the environnement determines wether a gene is expressed or not, here the mother that licks (environnement) causes the baby (gene) to lick (expression of gene), then isn't everything nurture? Sure the genes are the building blocks, but if the environnement decides which ones are used and which one aren't then can we really say nature is the determining factor here?

[@jimsourdif2374]

The fundamental premise of this video is flawed. Research has repeatedly shown that twins raised in different environments have similar outcomes and similar personalities. Clearly how a person turns out is a combination of genetics and environment, that is hardly some profound statement. However there is a reductionist sense of environment presented here. Positive and negative environments are presented as overt, obvious, and directly influential. This isn't the case in real life. There is an old Chinese proverb that wealth skips a generation. This is based on the fact that often people who develop in soft environments become soft and people who develop in hard environments become hard. However being hard or soft isn't expressed in "going to school" or "becoming a criminal", that is not the way an environment shapes someone. For example, one of the most important factors in determining a persons social success is their innate ambition. This is a psychological trait that is highly inheritable but tends to express quite differently depending on environment. Ambition tends to target levels of comfort and lifestyle rather then the "naked unlimited ambition", often presented. What that means is that two twins born in radically different environments tend to target the same social and economic strata as indicators of personal success. Research is fairly conclusive on this point and the outcomes of studies on separated twins strongly support it.

[@kayess718]

I was thinking of confirmation bias as I watched this video as well......

[@xanderguldie]

This is total bs, show me something to support your claim. Also in the video they explicitly say that it's a combination of the two. And there is no doubt about in as far as I'm concerned.

[@robertbowen5506]

I would recommend a film called Identical Strangers, a documentary about a longtitudinal study of triplets who were intentionally separated and raised by different families in different socioeconimic groups. Highly unethical study, and with very different outcomes than previous studies have indicated. The video is accurate to a point, for more information read Not By Genes alone, Richicherson & Boyd, 2005.

[@Ina-hh9nv]

research has shown that twins do have similar outcomes, but in cases in which they do not it is because of the impact of the environment which triggers the whole epigenetic process to occur. The video isn't wrong it's simply explaining why some twins may not have a similar outcome, if the environment is drastically different and at the end of two different spectrums then it's more likely the outcomes would be different as well due to epigenetics.

[@GoldKunai]

[@johnrobertson7231]

It is not necessary to study rats when there are studies of human twins and adoptees around that can yield relevant conclusions. The DNA revolution has made DNA personal by giving us the power to predict our psychological strengths and weaknesses from birth. A century of genetic research shows that DNA differences inherited from our parents are the consistent life-long sources of our psychological individuality―the blueprint that makes us who we are. Longitudinal studies of twins and adoptees have been going on for almost 50 years. Genetics explains more of the psychological differences among people than all other factors combined. Genetics accounts for fifty percent of psychological differences―not just mental health and school achievement but all psychological traits, from personality to intellectual abilities. Nature, not nurture is what makes us who we are. These studies lead to some some provocative conclusions ―among them that parenting styles don't really affect children's outcomes once genetics is taken into effect; unless you are a rat it seems.

[@WAKEUPARTIST]

So a gene's genetic potential is always defined and constant while only the expression is variable and contingent on environmental triggers? And what is responsible for interpreting the response to the triggers as positive or negative once certain behaviors transcend basic survival? Can a rat from a high licking parent actually interpret the licking in a negative way whereby it develops an aversion to licking that in turn causes it to become a low licking parent?

[@TiredHumanBeing]

I'm also not too well versed in epigenetics, but I can give you a story about someone I personally know who went through something similar, and what happened to him that changed him forever. This man had a mentally disabled mother, and a good father, up until this man who was then a boy, turned 10. At 10 his good father abandoned him and his mother. His mother married another, but this person, was a dragon in sheep's clothing. This dragon beat the 10 year old boy, not only beat, but literally tortured him. By the time the boy turned 15, he witnessed his monster of a stepfather rape and kill one of his two only friends. The boy turned the rapist in, and was finally free. See the boys stepfather turned the boy into a trouble maker. Constantly fighting, swearing and hurting others. Once his torturer was gone, he had an identity crisis. His mother wasn't fit for work so he took on the responsibility for providing for the remains of his family. He turned into a working man by age 17. His rage quelled by liquor. He got his booze however he could, and quickly became an alcoholic, at just 17. It helped him forget his past, but dulled his creative mind, cursing him to be but a grunt on the walk of life. By age 19, he found a woman who changed his life. This woman eased pain booze could not, so, he married her 2 weeks after they first met. He would spend the next 14 years, working, drinking, and spending time with his wife. The rage he had was just a relic of a by gone age. He still could feel the pain of his past, not even his wife nor his job could nullify it. By age 33 his wife gave him his eldest son. His son, was the painkiller he was searching for. He made a vow to stop his excessive drinking. He wanted to give his son the childhood he dreamed of when he was a boy. A year later his youngest son came to him. After leaving drink behind he became successful in his workplace, and a very caring husband and father. A few years later tragedy struck him. He had an accident and became disabled. Year by year the nerves in his body slowly die. Leaving him in constant physical pain. But even his defeated body could not break his spirit. He became an even more loving husband and father, and this love spread even outside of his family and into others. Today he has found peace in fishkeeping, family and friends, and his cars. He went from a drunken thug to a father of the whole neighborhood. He did this by keeping his eyes on the road ahead, and finding someone who could help him, then to building a new life of his own. He still bares the scars of his past, and sometimes he can still feel the pain, but always tries to keep himself busy. He spends less time thinking, and more time acting. Hopefully his story shows you that there is always hope, you just have to take life, one step at a time.

okay, so from the research I have gathered, not every trait can be influenced by genetics, such as lets say the way you look. Your environment will have a very minimal impact on the way you will look because your phenotype is largely genetics. However there are some traits that can be influenced by the environment and are found in your "epigenome" I think a lot more research needs to be done in this field to figure this out.
