ANSWER: Scientists compared the DNA of 108 white-footed mice, about half living in Chicago parklands and the rest from museum specimens dating back to 1855. They found the mice had experienced a surprisingly large shift in genes during this time -- a period that coincided with the increasing urbanization of their environment.
