The dog or domestic dog, (Canis familiaris[4][5] or Canis lupus familiaris[5]) is a domesticated descendant of the wolf which is characterized by an upturning tail. The dog derived from an ancient, extinct wolf,[6][7] and the modern grey wolf is the dog's nearest living relative.[8] The dog was the first species to be domesticated,[9][8] by hunter–gatherers over 15,000 years ago,[7] before the development of agriculture.
