In a continuation of what I have written previously about the behavior of human beings in recent times, I put the following summary of a scientific study that I found researching on the internet.
It is one of the most terrifying experiments in the history of science, which, through the behavior of a colony of mice, is an attempt by scientists to explain human societies. The idea for "Universe 25" came from American scientist John Calhoun, who created an "ideal world" in which hundreds of mice would live and reproduce.
More specifically, Calhoun built the so-called "Mice Paradise", a specially designed space where rodents had an abundance of food and water, as well as a large living space. At first, he placed four pairs of mice that in a short time began to reproduce, causing their population to grow rapidly. However, after 315 days their reproduction began to slow down significantly.
When the number of rodents reached 600, a hierarchy was formed among them, and then the so-called "miserables" appeared. Larger rodents began to attack the group, with the result that many males began to "collapse" psychologically. As a result, the females became protective and, in turn, became aggressive towards their young.
Over time, the females exhibited increasingly aggressive behaviors, elements of isolation, and reproductive disincentives. There was a low birth rate and, at the same time, an increase in mortality in younger rodents. So, a new class of male rodents appeared, the so-called "beautiful mice". They refused to mate with the females or "fight" for their space. All they cared about was eating and sleeping.
At one time, "beautiful males" and "isolated females" made up the majority of the population. Over time, juvenile mortality reached 100% and reproduction dropped to zero. Among the endangered mice, homosexuality was observed and, at the same time, cannibalism increased, despite the fact that there was an abundance of food. Two years after the start of the experiment, the last baby in the colony was born.
By 1973, he had killed the last mouse in Universe 25. John Calhoun repeated the same experiment 25 more times, and each time the result was the same. Calhoun's scientific work has been used as a model for interpreting social collapse, and his research serves as a focal point for the study of urban sociology.
