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:
“They didn’t know
how
my heart woke
to a range and measure
of song
I hadn’t known.”
—Hilda Doolittle (1886–1961)
“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)
“As to spelling the very frequent word though with six letters instead of two, it is impossible to discuss it, as it is outside the range of common sanity. In comparison such a monstrosity as phlegm for flem is merely disgusting.”
—George Bernard Shaw (1856–1950)
