I Simulated What Your Pet Rat Evolves Into After Humans Disappear

I Simulated What Your Pet Rat Evolves Into After Humans Disappear What happens to rats if humanity disappears and never comes back. No constant food, no predictable patterns, no system built around human life. Only empty structures and silence. I simulated what happens next. Some populations collapse fast. Others adapt immediately, spreading into new environments and shifting from scavengers to true survivors. Over time, only efficiency remains. Behavior sharpens, structures change, dependence disappears completely. They don’t become something new. They return to what they were always close to. 👇 What animal should I make next?
