The risk of improbable, uncertain, but grave potential dangers poses unique adaptive challenges. We argue that to manage such risks, a special motivational system evolved, which we term the security motivation system. Review of work across a range of species indicates that this system is designed to
We consider an individual-based model of evolution. Species emergence as segregation of the population on to discrete positions in a hyper-cubical genotype space. The model emphasises interaction between coexisting genotypes. Although the rate of the micro-dynamics, consisting of reproduction and ki
