Pulled from Google:
- the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
If I may, to state the simplest form of Nature plus Nurture above in an even shorter way –
Genes + Environment = Phenotype
– right? That’s the basis of it, isn’t it, and so the basis of the famous and never-ending twin studies? The opportunity to move genes around to different environments and see what changes and what stays the same?
Now, I’m not the first to point out that adoptable homes in adoption-capable countries are largely selected for similar socially acceptable reasons, but that’s just not clear enough; the problem is even more basic, and it’s in the definition above. The amazing, specific identical things that some of the separated twins showed that seemed to give all the power to the genetic side of the argument do the very opposite with more logic, prove the opposite.
These amazing parallels defy the phenotype equation, for starters. Either some of these behaviours and propensities are purely genetic, unaffected or unaffectable by environment, or the very impressiveness of the phenotypal match proves that there was no difference in the environment, at least no difference that would or could change that trait. Empirically. The same phenotype means same (relevant) genes and same relevant environment, by definition.
To my untutored mind, that looks like a huge fail. I’m sure the biologists have some long-assed answer that I’d need to be a geneticist or a statistician to argue with, but if they don’t have something to explain away the first rule, the basic syllogism, then . . . on the other hand, though, it’s an understandable conclusion, considering the setup. They move genes to new homes and hope they’ve made an environmental change, but really, we don’t know what it is that might have changed, do we? We’re black-boxing this “home environment” thing, we look at what we put in and what comes out as a sort of high level troubleshooting method, like how it’s done in electronic systems, when we can’t know the inner workings of some device. We really haven’t worked out what about the home environment does what . . . well, hadn’t, I mean. AST has, possibly.
The evidence has been right in front of us the whole time. There is no evidence for all the details of parenting styles, for anything “positive.” The evidence is for abuse, so that’s the environment factor that when we change it, we’ll see statistical results, changes in incidence of all that correlates with abuse, meaning problems. That is possibly the upshot of the adoptable home criteria as well: socially acceptable levels of structure, discipline, control, and abuse. When all that varies only within a narrow range, then it’s not going to matter how widely less important things vary.
Biologists, you want to convince us that parenting doesn’t matter? Change your test twins’ environment in a meaningful way, and there’s only one, level of abuse. You can’t arrange to have one tortured, so all you can do is try to raise some separated twins without discipline and punishment, that’s legal, I think.
Either that, or you’re going to have to explain to us how all the experiments that you say proved the power of our genes seem to disprove your most basic rule.
I don’t know why people never understand me in this way: this is a question, I have posed a problem here, and I’m looking for an answer, an explanation, an argument, something. Silence indicates assent and submission in court, but I don’t think I can make that conclusion here on the interwebs.
