Some aspects of the evolution of legal norms in the Lower Pleistocene. A quantitative approach to normativity

The research focuses on the relationship between normativity, law, and evolution of culture: legal normativity is represented as a cognitive trait allowing a temporal displacement useful for contemporaneous considerations of temporally detached realities, coupled with the trust in what ought to be. The mix-up between reality and representation in the first cave paintings allowed the hormones that regulate the trusting behavior at the brain level, to increase individual cooperative behaviors, leading to the introduction of egalitarian rules in sharing the prey, stabilizing the cooperation in the group and enabling culture to evolve.
