The term "domestic dog" is generally used forboth domesticated and feral varieties. The dog may have been the first animal to be domesticated, and has been the most widely kept working, hunting, and pet in human history. The word "dog" may alsomean the male of a canine species,[4] as opposed to the word "bitch" for the female of the species.
The present lineage of dogs was domesticated from gray wolves about 15,000 years ago.[5] Thoughremains of domesticated dogs have been found in Siberia and Belgium from about 33,000 years ago, none of those lineages seem to have survived the Last Glacial Maximum. Although mDNA testing suggests anevolutionary split between dogs and wolves around 100,000 years ago, no specimens prior to 33,000 years ago are clearly morphologically domesticated dog.[6][7][8]
Dogs' value to early humanhunter-gatherers led to them quickly becoming ubiquitous across world cultures. Dogs perform many roles for people, such as hunting, herding, pulling loads, protection, assisting police and military,companionship, and, more recently, aiding handicapped individuals. This impact on human society has given them the nickname "Man's Best Friend" in the Western world. In some cultures, dogs are also source ofmeat.[9][10] In 2001, there were estimated to be 400 million dogs in the world.[11]
Most breeds of dogs are at most a few hundred years old, having been artificially selected for particularmorphologies and behaviors by people for specific functional roles. Through this selective breeding, the dog has developed into hundreds of varied breeds, and shows more behavioral and morphological variation...
