How Mice Turned Their Private Paradise Into A Terrifying Dystopia
In 1972, animal behaviorist John Calhoun built a mouse paradise with beautiful buildings and limitless food. He introduced eight mice to the population. Two years later, the mice had created their own apocalypse.
The few secluded spaces housed a population Calhoun called, “the beautiful ones.” Generally guarded by one male, the females — and few males — inside the space didn't breed or fight or do anything but eat and groom and sleep. When the population started declining the beautiful ones were spared from violence and death, but had completely lost touch with social behaviours, including having sex or caring for their young.
