This paper is interesting and thought provoking in its claims - even though it's probably essentially wrong [tm] *. http://www.bioscienceresource.org/commentaries/article.php?= id=3D46 http://www.diabetesincontrol.com/index.php?option=3Dcom_content&view=3Darti= cle&id=3D10184&catid=3D1&Itemid=3D17 Fighting words: " As the analysis also points out, the findings resolve the biggest conundrum in human health. The epidemiological data have always indicated that Western diseases are determined overwhelmingly by diet and other non-genetic factors. Similarly, clinical data have frequently shown that many diseases can be reversed or accelerated by diet and other lifestyle choices. The crucial importance of the new genomic findings is therefore to show that genetic research does not after all contradict these environmental explanations of disease. Rather, it now very strongly supports them." Study by: Jonathan Latham, PhD, is Executive Director of The Bioscience Resource Project. Allison Wilson, PhD, is the Science Director and co-founder of the Bioscience Resource Project. I realise that it's rash for an educated but not overly informed layman to rail against such obviously confident statementsby so eminently qualified researchers. I have no hesitation in doing so. (Fools rush in ...). We'll see :-). I consider that it tells us as much or more about our knowledge of how genetics work as it does about what genetics currently tell us. Of interest is the observation": "The Great DNA Data Deficit: Are genes for disease a mirage? which will be published on December 9th, 2010, points out that the hiding places on which geneticists' hopes are now resting would require genes for disease to be located in places distinct from where almost all other genetic information has so far been found. These hiding places are thus scientifically highly implausible." Containing as it does the two points: - would require genes for disease to be located in places distinct from where almost all other genetic information has so far been found. and - These hiding places are thus scientifically highly implausible. I wonder how much information, the, is to be found in the places where we largely haven't found things, and what we have to do to improve the plausibility of mechanisms which are almost certainly [tm]* real world reality. Consider: Is it "plausible", based on your knowledge of human knowledge, that all major heart disease does not have a genetic component? For me, with a family history 4 out of 4 of severe heart disease a generation back on one side, and 1/1 2 back, that would be good news. For the many people for whom "cancer of some sort or other runs in the family" it would be equally good news. So too for depression, adhd (whether or not its "real", and all mental illnesses. The reality is that a major proportion of all these are clearly [tm] genetically biased from a layman's perspective. Allowance for conformation bias, lack of epidemiological evidence, probable presence of counfounding factors, small and biased samples and more, the evidence is still "clear"*[ tm] Why this is not evident to the researchers should make interesting reading as this survey is sure to be very widely quoted and discussed.
