  1. That is incorrect. Before I go into why, I think it is helpful to use the fitness landscape (https://en.wikipedia.org/wiki/Fitness_landscape) to visualise the process of evolution and it's progression over time. The landscape depicts the phenotype possibilities of a trait (e.g wing) that evolution can find by mutation. The fitness landscape varies in any given environment and changes if environment does, it is depicted by peaks (high fitness) and troughs (low fitness). Natural selection usually drives evolution upwards over time towards a peak (but not necessarily the highest peak in the lands
  2. I agree that the word can be easily misinterpreted, but the word causative is reasonable if one specifies what the cause refers to (the occurrence/incidence (e.g. throw a baseball) or the outcome variance (e.g curvreball, under arm throw, over arm etc.). The term "causative contributor" and predisposition overlap somewhat, perhaps entirely. If a predisposition (occurence or outcome variance) has a known genetic basis, then it is reasonable to say that genetics contributed to the cause of the particular outcome the predisposition relates to. Coming back to homophobia now. On the basis o
  3. To the OP, read my post there. I don't know much about Turner's syndrome or the physiology of it, but there are some clinically relevant genetic explanations. http://www.scienceforums.net/topic/70254-genetics/?hl=turner#entry711647 The points can be extended to klinefelters also. Though I don't know if 2 chromosomes in klinefelters will be inactivated by the inactivation system. How is this relevant to the OP's question? and what are you even talking about? Perhaps you can elaborate on this?
  4. Sarcasm? I already touched upon the useful point I felt he was raising. I didn't understand many of the points he raised, and I did agree with you about the false dichotomy he depicted. To be honest I succumbed to a lot of TLDR behaviour, I apoloise for that. I agree with you that religion is essentially hijacking the "good" already within us and claims that this good is rooted in religion. This point doesn't mean that the religious teachings, bible or whatever, do not contribute to the cause of good behaviours. As for the promotion of bad, you raised the examples of religion condo
  5. I was considering posting some of the arguments in the biology forum, but I think the discussion would become speculative rapidly. This topic concerns how we (society) determine whether or not an individual is responsible for an action, and for the sake of this topic the definition of responsibility is "being accountable for something within one's own power, control or management" (dictionary.com). I argue that the way in which we determine/quantify "one's own power/control" is inaccurate, and that most probably hold a mistaken view of responsibility (by thinking of it as simple discre
  6. I actually think Sam's criticism on some points was useful, the conversation just wasn't particularly useful though. With regards to religion causing good and bad. Where is the evidence for or against? and how valuable is the evidence (suggestive?, proof?)? can it explain how much religion contributes to the cause of both "good" and "bad" behaviour? Are your conclusions reasonable? and are you being unbiased here? I would take a guess that religion is a factor which can influence behaviour, though in reality there are many other factors which can contribute to an individual's behaviour
  7. Yes, that is correct. The data gives no insight into functional role. The data suggests that genetics accounts for a certain percentage of the observed variance in sexual attitues toward homosexuals. So one can say that genetics contributes to the causation of the observed behaviours, rather than saying genetics simply allows for the possibility of homophobic attitudes. That is a possibility that can't be refuted, yes. I disagree here. The correlations actually do suggest that genetics are a causative contributor of the observed attitudes toward homosexuals.

  8. http://www.ncbi.nlm.nih.gov/pubmed/21761238 This study reports heritability for violent crimes (convicted offenses I believe) in a Swedih population, and the authors note the results are similar to those obtained from a twin study using self-reported antisocial behaviour. It seems likely that genetics does contribute to the variance observed in antisocial behaviour. I guess it is fair to assume that genetics probably contributes to individual differences that concern douchebaggery related behaviour.
  9. It's also very important to consider sexual selection. OP seems to have not considered the possibility of sexual selection. My overall opinion is that there are many possible explanations, and that many of those explanations are as unsupported as each other. You can't see how violence can potentially be a successful strategy? like rape? how does evolution become unconcerned with a trait then? Evolution is not concerned with anything. Genetic drift (the randomness you were talking of) is an important contributor to the progression of allele frequency change and evolutio
  10. I think the observed higher prevalence of homophobia in heterosexuals is not doubtful, I believe there were other supportive references along with the same observation in the study population. I do agree that the blunt categories "homo, hetero and bi" are not ideal, but I think one can still draw a rather loose conclusion nonetheless. The criticism of the terms "homo, hetero and bi" should only go so far imo, sure they are blunt tools and do not allow for fine-tuned descriptions, but they still a useful measure when considered as self reported sexual identity. In this respect, the terms are us
  11. T "It is genetic" is a bad phrase. "Genetics contributes" is a better one. Explaining selection is a difficult feat. Detection of selection can be challenging also, and it usually requires DNA sequences (in this case we don't know what the contributing genes are, so no DNA to work with). It will be a while before we can provide reasonable explanations for selection that is backed with adequate evidence.
  12. I would like to see the adoption of such laws, and I would support a court case in which an individual seeks to sue his/her parents for the suboptimal lifestyle they caused. I don't expect tlaws such as these to be implemented any time soon, and maybe my prediction won't even come true. Ultimately, this is just my opinion on this subject area, and I believe it is more reasonable than the current laws. Much of your post was rubbish because it lacked explanation. My point was that the age of genetic counselling is irrelevant, and so is the 100,000 years of which you speak. Genetic counsellin
  13. You do raise a good point. Science can progress to find a cure in the future, but that doesn't help us now. We have a dilemma now, because we have the ability to reduce the risk of transmission yet it is still considered acceptable to subject future children to these risks. Imo, even if the laws I propose go obsolete it is better to brdge the gap and prevent harm rather than do nothing and leave people to consider these risks as acceptable. It just doesn't make sense to ignore the techology we have today, the law I propose would promote its use somewhat. You say "recently", but genetic
  14. It only occured to me just yesterday to actually look on pubmed for some scientific literature on this topic, seems I was infected by the bad reasoning e-virus present in this thread. I think it is important to point out that exposure to (or awareness of) homophobia and what causes one to adopt a homophobic mentality should be considered separately. I can't stress this enough, and I think people in this thread may have been arguing (without saying) for either or, or perhaps both. I think this can lead to confusion, especially when considering the homophobic baby line of reasoning (which bt
  15. So does it also disturb you that very unpleasant diseases like Huntington's disease still exist today? HD prevalence could almost be reduced to de Novo mutations only, if people placed more value in their child's wellbeing. I wonder if the families segregating those traits feel guilt for deciding to initiate the high risk biological coin flip that determines their childs wellbeing. Whilst I myself agree with the adoption of laws on this topic that would deny certain people the choice to procreate, I have suggested the adoption of laws that wouldn't. I do think it is reasonable (and I thi
