The origin of the domestic dog (Canis lupus familiaris) began with the domestication of the Grey Wolf (Canis lupus) several tens of thousands of years ago. Genetic and archaeological evidence shows that humans domesticated wolves on more than one occasion, with the present lineage of C. l. familiaris arising probably roughly 15,000 years ago as evidenced by the Bonn-Oberkassel site, 14,000 years ago.
Domesticated dogs provided early humans with a guard animal, a source of food, fur, and a beast of burden. The process continues to this day, with the intentional artificial selection and cross-breeding of dogs to create new breeds of dogs.

In an old cellar hole in a byroad
The origin of all the family there.
Thence they were sprung, so numerous a tribe
That now not all the houses left in town
Made shift to shelter them without the help
Of here and there a tent in grove and orchard.”
—Robert Frost (18741963)

—Ralph Waldo Emerson (18031882)
“To meet the objections of some inveterate cavillers, I may as well state, that if I dined out occasionally, as I always had done, and I trust shall have opportunities to do again, it was frequently to the detriment of my domestic arrangements.”
—Henry David Thoreau (18171862)
