Description In 1968 John B.
Deprived of motherly love early in life, and denied access to social roles later in life, young mice grew up without knowing how to.
Over a 41/2 year period the population exploded into a colony of 2200 mice, and then slowly and inexorably declined to extinction.
Calhoun, American behavioral ecologist, introduced eight mice into a technologically designed walled enclosure that fulfilled all the wants and needs of mice except migration in and out.
