DNA discoveries are revealing why even the best parenting doesn't have the effects experts promise, from breast-feeding to letting kids learn from mistakes.
....
In about 30 percent, the coils of their DNA carry a glitch, one that leaves their brains with few dopamine receptors, molecules that act as docking ports for one of the neurochemicals that carry our thoughts and emotions. A paucity of dopamine receptors is linked to an inability to avoid self-destructive behavior such as illicit drug use. But the effects spill beyond such extremes. Children with the genetic variant are unable to learn from mistakes. No matter how many tests they blow by partying the night before, the lesson just doesn't sink in.

Are we slaves to our DNA, or can we as humans overcome our limitations?

Seriously though, haven't you read the twin studies? Where identical twins, raised in different socioeconomic studies, end up exactly the same. Even marrying wives with the same name!

Note that it is a combination usually of nurture and nature. But random variations of genetic structure are ways that the species experiments with change. If certain variables work in certain niches, then those variations are at a 'select' advantage to multiply and become more commonplace within the gene pool.

And there is more here than just an imballance with dopamine. There are other brain chemicals, such as serotonin, which is what I have less to spare as I age. That is why I need a good "reuptake inhibitor" to keep the serotonin between the cell synapsis.

But there is alway hope for the future of genetic engineering.

Since companies already offer storefront DNA tests, the day is not far off when parents can determine their child's MAOA or DRD4 status, or the presence of any other variant that influences the effect of parenting. But perhaps it is time to acknowledge that there is only so much influence parents can have. In her best-selling book "I Feel Bad About My Neck," Nora Ephron laments how American society "came to believe in the perfectibility of the child just as it also came to believe in the conflicting theory that virtually everything in human nature was genetic." Both views—that everything is genetic and that parents can transform a child like a lump of clay—are as wrong as wrong can be.

And speaking of DNA, there is this. We take glasses for granted, and don't even consider what life must have been like, in the good old days, when glasses were not present.

Quote:
The study matches findings in other countries that have shown about half the population has a so-called refractive vision problem, usually requiring the use of glasses, contact lenses or corrective surgery.

The causes of these three eye conditions is unclear but there is a genetic component. Most studies discount the widely held belief that myopia is caused by too much reading or close work as a child.


I can remember my Mother using that last one on me about reading under my bed covers, or reading in a low light environment. Some tales never seem to go out of style.

Bah, more excuses for more mistakes. We are in a culture of no consequence these days.

DNA I think, is irrelevant, how does one just ignore the stigma of something being wrong, or being told it's wrong, or forgot that he or she will go to jail for that?

Alchoholism runs in my family, cutting a wider swath than the Amazon - why am I not one of these yet caught up in the current, even though I have the disposition to be one (I have an addictive personality)?

I have had plenty of bad examples to choose from, and why haven't I followed them?

I can drink like a fish, and have since I first tasted the glory of beer and liquor, but I have no problems with a dry spell, or giving it up for the time being due to other circumstances.

Same with my Copenhagen. Right now, due to it's inconvience out here, I have given it up with no problem. Might never do it again.

I think while we are made up of genes, that reason and following reason are completely able to overcome it.

People do need to be held accountable, no matter the cause of their behavior. But its possible to believe that people should be held responsible for what they do, *and* that what they do is largely determined by their innate personality. Free will and accountability don't necessarily go hand in hand.

Don't they say, of identical twins, one always has a slate loose? I'm not sure how viable studies like the one you told are. Here's a case that could reveal a lot, first if the two twins are identical, or the one growing up in the believe to be a twin is very different. What a shame they decided to remain anonymus.

Agreed.

for instance, if an person who were obviously mentally ill killed an dozen people, that person should be held accountable somehow. it'd be an disservice to the victims and their families if he was "let go" into an asylum for a few years as opposed to hard time in Prison just because he "couldn't help himself".

There are prisons made for the criminally insane, people. let's put them to good use.

And like Gunnen said, Reasoning and strong will can also help people overcome some mental disorders and illnesses, etc..... with some help from medication too if that's what it takes.
For every exermete case you show me where an person who has an certain disorder who can't take care of himself/herself, I bet you that I can also find another person with that same disorder who has overcome it and is living an normal life.

That isn't to say that we shouldn't take this kind of study seriously, as seeing I'm sure for some it can be a rather powerful impulse. I'm just not keen on saying that it can't be overcome.

I'm cynical about how much we humans are really capable of overcoming our innate tendencies and personalities. People don't overcome mental illness per se, they just learn how to deal with it.

We do have predisposition to do this or that. All of us have various desires to do this or that.

The difference is for example,my father was hot tempered,so am I.

Dad let his temper rule his life,I struggle to maintain mine at the lowest heat I can. Yea,I struggle with it,but I actively seek to crush my hot temper,dad simply allowed his to control his life. Dad liked to drink,so do I,dad let drink rule his life,so far I have been able to drink with a level of moderation. I have desired to kill men before,but I haven't followed through,others desire to and follow through.

There are other examples.

Jeffrey Dahmer did what he did. We now know based on his father's autobiography that HE had the same lusts to murder and EAT his vicitm,but he never acted on the lust. Jeffrey did.

One was guilty,the other learned how to control his desires,bizarre as they were.
