Epigenetics

Updated: 4 July 2018 Epigenetics is an approach that helps to explain how nurture shapes nature to produce the phenotype from the genotype – in other words, how you become who you are from your genetic potential. In the words of Mark Solms & Oliver Turnbull (2002, p11): “…the fine organisation of the brain is literally sculpted by the environment in which it finds itself – far more so than any other organ in the body, and over much longer periods of time.” Whilst in no way undermining the importance of Genetics, it does undermine genetic determinism because it allows that virtually everything in the life span of an individual – from diet and nutrition, to ingestion of toxins, to social experiences, etc, etc – can influence the expression of genes to produce differences in motivation, temperament, cognition, behaviour and mental health. Bruce Lipton (2008) has put forward evidence to claim that emotions and even unconscious beliefs can bring about epigenetic modification.

Today, of course, Cameron’s at war with a number of his own backbenchers over the intention to fix the level at which Parliament can be dissolved prematurely at a vote of 55% of the House of Commons (up from a simple majority of 51% and making it that much more difficult to get rid of them). At least the Lib Dems are only being berated for this ‘stitch up’ by members of another party (Labour)! Undoubtedly the week since the general election results were declared has been one of the most interesting in modern British politics! The 55% no-confidence level stitch-up is, in fact, a key plank… Read More
