Well not to long ago, in Moscow of all places, some scientists started studying metro dogs. These are dogs that have lived down in the subway system for years and ride the subway to find food. They actually know which stops they get on and off of the trains to look for food or go home at night to sleep. One of the new skills these dogs have is “the hunt for shawarma”. An interesting side affect of living in the metro is they have been unintentionally, selectively breeding for more wild traits: fear of humans, ability to scavenge. And have come to resemble wild dogs more then their domesticated ancestors.

They look so cute!
