We argue that focusing on the environment as if it consisted only of social (or sociocultural) factors gives too limited a perspective if evolutionary approaches are to understand the behavior of modern humans. Taking the case of violence, we argue that numerous novel environmental factors of nutritional and physical-chemical origin should be considered as relevant proximate factors. The common thesis presented here is that several aspects of the biotic or abiotic environment are able to change brain chemistry, thus predisposing individuals to violence and aggression in given contexts. In the past, aggressive behavior has a number of useful functions that were of particular importance to our ancestors' survival and reproduction. However, some of the conditions in our novel environment, which either lowered the threshold for aggression or released such behavior in contexts which were adaptive in our evolutionary past, no longer apply. It is high time evolutionary approaches to violence are expanded to include the possibilities that violence may be triggered by nutritionally depleted foods, reactive hypoglycemia caused by habitual intake of foods with a high glycemic index (GI), food allergies/intolerances and exposure to new environmental loxins (heavy metals, synbetic poisons). - Reproduced.  aPsychology  aViolence  aPoleszynski, Dag Viljen  aSocial Science Information  a55916  c55916d55916  00104070aIIPAbIIPAd2018-07-19hVolume no: 42, Issue no: 1pAR56361r2018-07-19w2018-07-19yAR
