Range
The Virginia opossum is found throughout Central America and North America east of the Rockies from Costa Rica to southern Ontario; it seems to be still expanding its range northward and has been found farther north than Toronto. In recent years their range has expanded west and north all the way into northern Minnesota. Its ancestors evolved in South America, but invaded North America in the Great American Interchange, which was enabled by the formation of the Isthmus of Panama about 3 million years ago.
Originally native to the eastern United States, it was intentionally introduced into the West during the Great Depression, probably as a source of food, and now occupies much of the Pacific coast. Its range has been expanding steadily northwards into Canada.

Famous quotes containing the word range:
“but we wish the river had another shore,
some further range of delectable mountains,”
—Robert Lowell (1917–1977)
“In the range of things toddlers have to learn and endlessly review—why you can’t put bottles with certain labels in your mouth, why you have to sit on the potty, why you can’t take whatever you want in the store, why you don’t hit your friends—by the time we got to why you can’t drop your peas, well, I was dropping a few myself.”
—Mary Kay Blakely (20th century)
“Culture is the suggestion, from certain best thoughts, that a man has a range of affinities through which he can modulate the violence of any master-tones that have a droning preponderance in his scale, and succor him against himself. Culture redresses this imbalance, puts him among equals and superiors, revives the delicious sense of sympathy, and warns him of the dangers of solitude and repulsion.”
—Ralph Waldo Emerson (1803–1882)
