In evolutionary models where cooperators and defectors are perfectly distinguishable and cooperators working together do better than defectors, cooperators will tend to outcompete defectors over time. This is because cooperators gain higher payoffs from their interactions, which translates into a higher reproduction rate for cooperators compared to defectors. As a result, defectors are destined for extinction as cooperators spread through the population.
