In Moscow, there are stray dogs that learned to commute to downtown from the suburbs to scavenge for food. The dogs prefer the less populated cars at the beginning and end of the trains and they stick together to help each other so they don’t miss the right exits. They even learned how to use traffic lights to cross safely. Every evening, they ride back home to the suburbs where they hang out for the night. This has been going on for 20 years, several dog generations. Clearly, they teach each other.
I think we don’t give animals enough credit. They really aren’t very different from us.
