Urban Animals Still Evolve

And Moscow’s wild dogs and beggar dogs are proving it:

[B]eggar dogs have evolved the most specialized behavior. Relying on scraps of food from commuters, the beggar dogs can not only recognize which humans are most likely to give them something to eat, but have evolved to ride the subway. Using scents, and the ability to recognize the train conductor’s names for different stops, they incorporate many stations into their territories.

Could uplift happen by virtue of environmental shift alone?
