 Man's Best Friend: The Dog

The dog (Canis familiaris or Canis lupus

 familiaris) is a domesticated descendant of the wolf. Also known as the domestic dog, it was selectively bred from an extinct population of wolves during the Late Pleistocene by hunter-gatherers. The dog was the first species to be domesticated by humans, over 14,000 years ago and before the development of agriculture. Experts estimate that due to their long association with humans, dogs have gained the ability to thrive on a starch-rich diet that would be inadequate for other canids.
