Does Crime Leave a Genetic Trace? 160

Posted by Soulskill from the finally-an-explanation-for-the-hamburgler dept.
gallifreyan99 writes "Scientists have spent decades trying to understand and fix social problems like violence and alcoholism, usually focusing on the poor and disadvantaged. But now a small band of researchers is claiming that biology plays a vitally important role — because trauma can change you at a genetic level that gets passed on to kids, grandkids, and perhaps even beyond." Part of the research involved testing the effect of stress on the genetics of mice. A number of mice were subjected to stressful situations and then allowed to raise their children. The children, when later subjected to stress, were more vulnerable to it than normal mice (for example, they would stop struggling in a potentially fatal situation earlier than 'happy' mice). This was expected. What's interesting is that when those children were later bred with normal mice, and that third generation was raised by normal mice (so that parental neglect wasn't a factor), they still showed the same vulnerability to stress. A subsequent generation showed the same.

      ... fertilization. I think it was the NYT that discussed this a week or two ago. A woman who carried a gene for a cruel genetic disease wanted to have children, but not to pass on the disease. So she opted for In Vitro Fertilization, with the fertilized zygotes being genetically tested. She has had I think two or three children from zygotes that tested negative. If everyone who carries her disease gene does this, than a rare but terrible scourge could be eliminated from the earth. Her father, for example, is doomed to die young and is already suffering. However I myself have Bipolar-Type Schizoaffective Disorder [warplife.com]. It is as yet unclear whether that is a unique disease or the, uh, "lucky" combination of Manic Depression and Schizophrenia. The cause of Schizophrenia is as yet unclear but is thought to be due to infectious disease of the brain. It may have other causes, as it is likely to be more than one disease, each of which causes the psychotic symptoms of delusions and hallucinations. Manic Depression is quite clearly genetic, due to studies in which twins were adopted out to different parents at birth. There is a strong correlation between whether one twin is Bipolar, and whether the other is. That can't be due to environmental factors, or how one is raised. Manic depression is arguably a horrible disease. I myself have attempted suicide in a serious way a number of times, the last time in 2010 when I wrapped my car around a concrete highway overpass post at a hundred miles per hour. But dammit I forgot to unbuckle my seatbelt. It was a sudden decision, the end it all, you see. However Manic Depressives are well-documented to be uncommonly creative. Besides coding, I have a BA in Physics, while I did not complete my doctorate I stymied my fellow students, even the faculty, with my insight into the nature of reality when was in grad school. I draw, paint, sculpt, compose for and play the piano, sing and play drums. I invent all manner of things. I could have lots of patents if I could be bothered to ever file for them. Kay Redfield Jamison is a noted authority on manic depression, and a Johns Hopkins University psychology professor. She speculates that Manic Depression has persisted through evolution despite its obvious disadvantages because "it brings new ideas into the social consciousness". Hollowell and Ratey propose a similar theory for why Attention Deficit Disorder has persisted through evolution as well. Their theory is that people with ADHD are able to connect otherwise unrelated ideas in a way that the brains of normal people would be incapable of, thereby synthesizing novel ideas. For example despite being bent on suicide the whole time I worked at Medior, I invented then implemented a novel lossless bitmapped graphics compression algorithm and format, that enabled the company to stuff more assets on its multimedia CD-ROMs. Now suppose you chose In Vitro Fertilization because you or your mate had spent your whole lives contemplating suicide. You have a choice of a normal zygote, or one that will quite obviously bear a child who will be Bipolar as an adult. Which one do you choose? Were manic depression eliminated from the species, what would our society be like a thousand years from now? Jamison's new ideas wouldn't be getting contributed to the social consciousness nearly as much anymore.

Lamarkianism relies on a feedback mechanism to pump info back into genes, which is far more complicated that natural selection, where variation introduces info into genes, then the less-well-adapted genes survive less well and are replaced in subsequent generations by omission.

      This is probably more related to epigenetics, where certain chunks of DNA are coated to stop their effect, and this can be responsive to the environment as well as passed down to children.

      Also the exact causal relationships, if any, between stress, abdominal belly fat deposition (in the gut), and things like heart disease and insulin resistance, and even bacterial fauna population differences is also a hot area of research, and much of thatccan be passed on via non-DNA methods.

      In the broad general understanding that the environment can induce acquired changes that can then be inherited, yes. It's called epigenetics, and it's a fascinating field, wherein modification of packaging on DNA affects how and when it is read.

      In the specifics of pretty much any of the claims made by Lamarckian adaptation, no, that's bunk.

      One of the major differences is that epigenetic changes aren't always adaptive; that is, they aren't necessarily helpful to the organism's reproductive success. These changes can result from environmental stresses as a kind of "side effect", and the change affects later generations. Epigenetic changes are inherited, but they can be reversed in as little as a generation or passed on, and they are never responsible for new transcripts or proteins being produced. They modify amounts and timing of products from existing genes - and that's impressive - but they do not introduce novel products on a cellular level, the way changes in genetic code does.

I’m not saying there is no epigenome, but why would it work in an apparent anti-Lemarkin fashion, let alone anti-Darwinian? The implication is that nobody gets bad-genes, just that genes get shunted aside for multiple generations due to changes in the epigenome.

    I think there is some huge motivation on the part of the research here to explain why certain segments of the population remain in a loop of poverty and violence. I think social factors can adequately explain the problems we see. Perhaps there is a genetic component as well to why some groups do better than others, but research of that kind routinely gets the authors in trouble. Here we can have a quasi -genetic predisposition explanation that does away with the shame of having bad genes and suggests that it is society’s fault for not preventing the stressors in earlier generations that lead current generations to underperform.

    What is a little strange is the implication that the changes to the epigenome stay permanently, of course only if they are negative changes.

      Good analysis. If you look at the following graphics, http://epp.eurostat.ec.europa.... [europa.eu] you find massive (in some countries up to 20%) changes in Homicide rates within less than five years. I just don't see how genetics would be of any help if you want to understand these trends.

      • There has been a massive reduction in all crime over the last 40 years, which coincidentally started just about the time they widely banned widespread lead use, particularly in paint and gasoline. And that the last generation routinely exposed to lead paint and gasoline during their 0-20 years is the baby boomers who are in the process of retiring.

          It is difficult to confirm, but lead was phased out of alcohol on different dates in different parts of the country. By looking at the on time sequence of phase out with the time sequence of onset of crime rate reduction, we could see if there is any correlation. And Rick Nevin did look. He found a correlation. Leaded gasoline was a significant cause for the crime. (Just stay away from the home page.

      Your critique is flawed.

      It may well work in both directions, but the researchers did not investigate the transmission of positive behaviors. I wouldn't be so quick to discount the results. We are still learning about epigenetics, and there is tremendous knowledge still to be gained. Part of the problem is that the mechanisms of epigenetics are largely invisible to sequencing technology. Our knowledge of epigenetics is hobbled by this.

      We already know that dietary factors can be transmitted epigenetically

    • If you think about it epigentics gives an organism tremendous adaptive capability. Sad to say, but in hard times crime does pay....

    • I guess it depends on what you mean by 'bad'. Epigenetics gives an organism a tremendous adaptive capability- and like it or not, under severe environmental pressures 'crime' does pay.....

    • Just because you don't like the politics of science doesn't mean it can't be true. It may well be shown that this research is flawed and their conclusions are wrong. Likewise, the fact that there is one study that seems to indicate it doesn't mean we should all jump on the bandwagon to do whatever people see as the logical outcome of this finding.

Essentially they are lost souls. They go from one bad situation to another and make poor choices simply because they can't understand a normal life. And even though people try to do better later in life they have a lot of emotional baggage from their youth that comes back to haunt them. And that is when history repeats itself.

    I'm pretty sure the amount of lead in the environment is a more useful predictor of violent behavior than genetics.

    If you look at violent crime in the US, for instance, you see a big drop-off starting with the generation after the regulations were put on lead.

      This was a study on rats. I think it is a bit premature to conclude anything about humans from it, but certainly it is suggestive.

      Lead may very well be a major contributor to violent behavior - it might even be the largest one. That doesn't mean that there aren't others as well. People are complicated; there is no one cause for anything that a person does.
