When did the Dog Become a Domestic Animal?

It is difficult to imagine what the mankind's destiny would be without taming of various animals by our ancestors. At present more than 1,5 million animals are described; only about 50 of them have been domesticized. Dogs have inherited many mores and many behaviour traits from their ancestors, wolves. Wolves have worked out a range of socialrelations and their own body language. Only wolves are capable to show a menacing "clasped-jaws grin" when they demonstrate their clenched teeth, domineering individuals raise their tail to show their status.

 

 

These complicated social behaviour does for good training abilities of dogs. Also owing to this dogs could adjust to people and became one of the most prosperous animal species of the world. Of course, small kinds of dogs do not look like their ancestors but this is due to human century-long efforts to do selection work. Specalists' opinions differ in details of dogs' ancestry but they are united in understanding that human influence has played an important part in forming of kinds of dogs. 

First dogs were domesticized in particular regions of Siberia and Europe about 15000 years ago. Recently remnants of a skull with specific dog signs were found in Europe. This finding ages no less than 30000 years. Emigrants from Siberia surely crossed Bering's strait in company of their true friends. Some experts believe that it was in that time that people started to use sledge dogs. The earliest archaeological findings of domestic dogs in North America are dated as 9000 years ago. At that period dogs were the only domestic animals there. Dogs bore the burden of migration of tribes of navajos and apachees 1400 ago. Usage of dogs as working and sledge animals continued even after appearance of horses in North America. Nevertheless, it has been proven that all aboriginal dogs of Americaand the majority of dogs in the world come from wolves that were domesticized in China about 15000 years ago.  

 

Enhanced playfulness in comparison with wild ancestors, is explained by phenomenon of infantilization which is quite common during domestization process. In other words, a dog is in a sense like a grown-up puppy of a wolf. This is why dogs are loyal to their masters and are always appy to communicate with them.
