Urban evolution

Tomorrow’s NY Times carries an article on the rapid pace of evolution in urban areas: since cities have very different environmental conditions than natural areas, and urban conditions isolate populations from one another, creatures evolve more quickly than scientists ever expected. For example, within a short time, say a couple of hundred years, a group of birds or other animals might become tamer and less frightened of people, or able to eat different foods, or more tolerant of pollution than their rural counterparts. In other words, well on the way to becoming a separate species.
