It possibly shines a light on dog evolution, if domestic dogs didn't exist then the "beggars" who have attuned themselves to human feelings would be good candidates for domestication.
Neuronov says there are some 500 strays that live in the metro stations, especially during the colder months, but only about 20 have learned how to ride the trains. This happened gradually, first as a way to broaden their territory. Later, it became a way of life. “Why should they go by foot if they can move around by public transport?” he asks.
“They orient themselves in a number of ways,” Neuronov adds. “They figure out where they are by smell, by recognising the name of the station from the recorded announcer’s voice and by time intervals. If, for example, you come every Monday and feed a dog, that dog will know when it’s Monday and the hour to expect you, based on their sense of time intervals from their biological clocks.”
