Resumen de New York's mice are evolving to eat a city diet
There are always better restaurants in the city, and that could be making the town mice of New York genetically distinct from their country cousins. Stephen Harris at the State University of New York and Jason Munshi-South of Fordham University in New York City caught 48 white-footed mice (Peromyscus leucopus) from three New York parks and three nearby rural areas.

They examined the mice's RNA to see if the rural and urban populations expressed different genes
