Cooperation leads to intelligence. In fact, researchers believe that Intelligence correlated with the size of a brain’s neural network. But experimental evolution of vertebrate brains is impossible but there’s a way to measure the evolution of human intelligence through artificial intelligence. In fact, this is the best way to evaluate the plausibility of the hypothesis. Luke McNally, a Ph.D. student of Trinity College in Dublin’s Theoretical Ecology Research Group, conducted the study with colleagues Sam Brown and Andrew Jackson. They created digital organisms that electronically evolved ‘brains’. The researchers found that, the digital organisms typically started to evolve more complex brains when their societies began to develop cooperation which clearly signifies the idea that cooperation helped to drive the evolution of intelligence in at least certain species.
