(Lea & Chambers, 2006). “Maori violence blamed on gene” : “…goes a long way to explaining some of the problems Maori have. Obviously, this means they are going to be more aggressive and violent and more likely to get involved in risk-taking behaviour like gambling”. The Dominion Post, Wellington, 9 August 2006. Lee & Chambers, (2007): Maori used to be fearless warriors . Dangerous migration from Polynesia to New Zealand . Current population had survived tribal warfare . Evolutionary survival of the fearsome: 15% of NZ population . Argue unethical and unscientific to ignore the difference CNN Counter-point: 34% Caucasian, 56% Maori, 54% Chinese Zhang et al. (2016) What specific genes are associated with violence and antisocial behavior? Candidate Gene Approach (Vassos et al., 2013) . Meta-analyses of 185 studies of violence and aggression . 31 genes examined – no significant effects . Genes may interact with the environment . Gene x Gene interactions possible GWAS Approach (Viding et al., 2010) . GWA study on 8,374 children . Examined 642,432 SNPs . No SNPs significantly associated with antisocial / psychopathic (CU) behavior Summary: Genetics 1. Genes account for about 50% of antisociality 2. Genes interact with the environment 3. Which genes?
