In the 1960’s, a scientist named John Calhoun created a “mouse utopia” where populations of mice would enjoy everything they needed, essentially without effort: Unlimited food, water, living space, population growth without predators and so on. It started with eight mice, who began to reproduce quickly, enjoying their newfound “utopia” with unlimited resources. Within 4 years, however, the population had become extinct through self-annihilation even though all the resources it needed for survival were readily available, including ample space to live.
