The truth and origin of dog ??

There are many thoughts and hypotheses, but in reality, we do not have an accurate timeframe regarding the exact origins of the dog or its domestication history.

We do know that its closest ancestor is the wolf, taxonomically it forms part of the group of animals called Canidae, these include wolves, jackals, coyotes, dingoes, and foxes. It is now widely accepted that Canis lupus familiaris (originally classified as Canis familiaris) reclassified in 1993 by the Smithsonian Institute to reflect its wolf ancestry, has wolf like traits and is almost certainly derived from wolf stock.
Today's domesticated dog is probably a mutated form of the smaller Middle Eastern wolf. Archaeological evidence points to a time-period some 12000 to 15000 years ago when we started creating permanent settlements.
