Artificial Neural Networks Demonstrate the Evolution of Human Intelligence

samazon (2601193) writes "Ph.D. students at Trinity College in Dublin have constructed an artificial neural network model to demonstrate the Machiavellian intelligence theory — that human intelligence evolved based on the need for social teamwork and indexing a variety of social relationships and statuses. (Abstract) The experiment described in detail here involved programming a base group of 50 simulated "brains" which were required to participate one of two classical game theory dilemmas — the Prisoner's Dilemma or the Snowdrift game. Upon completion of either game, each "brain" produced "offspring" asexually, with "brains" that made more advantageous choices during the games programmed to have a better chance to reproduce. A potential random mutation during each generation changed the "brain's structure, number of neurons, or the strengths of the connections between those neurons," simulating the evolution of the social brain. After 50,000 generations, the model showed that as cooperation increased, so did the intelligence of the programmed brains."
