The "Universe 25" experiment
The larger rodents began to attack the group, with the result that many males begin to "collapse" psychologically. As a result, the females did not protect themselves and in turn became aggressive towards their young. As time went on, the females showed more and more aggressive behavior, isolation elements and lack of reproductive mood. There was a low birth rate and, at the same time, an increase in mortality in younger rodents. Then, a new class of male rodents appeared, the so-called "beautiful mice".
We are currently witnessing direct parallels in today’s society..weak, feminized men with little to no skills and no protection instincts, and overly agitated and aggressive females with no maternal instincts.
