Social Paradise (4 photos)

How to paradise? It is hard to say, at least for human beings. In 1972, John B. Calhoun tried to make a haven for mice: a square tank, two by two and a half meters in height. Food, temperate climate, purity, with females, horizontal and vertical strokes for males. In heaven sent four pairs of healthy, purebred mice.



After 104 days they will have first offspring. Parents care about kids. In the "Universe 25" (so called experiment) the golden age. Mice love each other every 55 days and the population doubles, only after 315 days of growth has slowed. In the universe is now 25 lived more than 600 mice. Male has become more difficult to defend their territory, is now on the moves needed to squeeze free social roles was nearly empty as space. There were "outlaws" and they began to gather in groups in the center - their attacks met fierce resistance. Soon mother became hysterical - to attack their children, the birth rate fell.



Females single moved into the uppermost hard nest, and among males became increasingly observed pronounced narcissism. These males do not fight, did not want to carnal pleasures - they just ate, slept and and introspect. But at the same time, in the far corners flourished cannibalism svalny sin and violence. After 18 months, the growth of murine universe finally stopped. And in a month (600 days from the beginning of paradise), with a very low number of new pregnancies, the mortality molodnika reached 100 percent. Nartsissiruyuschie males and hid in a distant female burrows lost the desire and the ability of social mate.



Murine society collapsed. Paradise turned into hell. All died. Good scientist repeated the experience many times, but the result was the same: at a certain point, the explosion of violence and asexuality followed hypersexual activity and self-destruction.

Finally, a little positive. Who was the longest to survive in Hell? It turned out - that this is the mouse that can handle the largest possible number of social ties. In the Universe 25 the longest surviving the most sociable, innovative, smart-ass mouse.
