In 1972 , fauna behaviorist John Calhoun build up a black eye Eden with beautiful buildings and illimitable food . He introduced eight black eye to the universe . Two years afterward , the mouse had created their own Revelation of Saint John the Divine . Here ’s why .
Universe 25 was a jumbo box design to be a rodent utopia . The hassle was , this Zion did not have a benevolent Jehovah . John B. Calhoun had design quite a few mouse environments before he suffer to the twenty-fifth one , and did n’t gestate to be watching a well-chosen story . Divided into “ independent square ” and then subdivided into level , with ramps going up to “ apartments , ” the billet looked smashing , and was always kept stocked with solid food , but its indweller were doomed from the get - go .
Universe 25 take up out with eight mouse , four male and four females . By day 560 , the mouse population make 2,200 , and then steadily declined back down to unrecoverable extermination . At the peak population , most shiner spent every living second in the caller of century of other mice . They gathered in the independent squares , waiting to be fed and now and then assail each other . Few female carried pregnancies to terminus , and the single that did seemed to merely block about their babies . They ’d move half their litter away from danger and leave the rest . Sometimes they ’d dismiss and abandon a babe while they were carrying it .
The few secluded spaces house a universe Calhoun foretell , “ the beautiful ones . ” broadly guarded by one male , the females—- and few male — inside the blank did n’t breed or struggle or do anything but eat and groom and nap . When the population started declining the beautiful ones were spared from violence and death , but had altogether mislay jot with societal behaviors , including have sex or caring for their youthful .
In 1972 , with the baby boomer come up of age in a ever - more - crowded humankind and report of public violence in the cities , Universe 25 expect like a Malthusian nightmare . It even acquired its own attention-getting name , “ The Behavioral Sink . ” If starvation did n’t vote out everyone , mass would demolish themselves . The good option was to flee to the rural area or the suburbs , where people had distance and life was peaceful and natural .
Today , the experiment rest fearsome , but the nature of the care has change . A late study pointed out that Universe 25 was not , if look at as a whole , too overcrowded . penitentiary , or “ apartments ” at the very remainder of each hallway had only one entryway and exit , making them loose to guard . This let more strong-growing territorial males to limit the number mice in that playpen , overcrowding the repose of the world , while isolating the few “ beautiful ace ” who lived there from normal society . or else of a population job , one could argue that Universe 25 had a honest dispersion problem .
The fact remains that it had a problem , and one that eventually result to its end . If this doings is shared by both mouse and humans , can we escape Universe 25 ’s fate ?
