Some genetic studies have documented evidence of early domestication events in specific regions. It was a process that unfolded over thousands of years-likely involving dog populations that appeared in different parts of Eurasia at different times, with dogs and wild wolves continuing to interbreed with one another and with early dog populations being replaced by later ones. Most studies agree that domestication was not a single discrete event. In this region wolves likely facilitated their own domestication by trailing nomadic people in northern Eurasia and consuming the remains of game animals that hunters left behind. There is strong genetic evidence, however, that the first domestication events occurred somewhere in northern Eurasia between 14,000 and 29,000 years ago. The timing and location of dog domestication is a matter of debate. Genetic evidence suggests that dogs descended directly from wolves ( Canis) and that the now-extinct wolf lineages that produced dogs branched off from the line that produced modern living wolves sometime between 27,000 and 40,000 years ago.

Over the millennia Cynodictis gave rise to two branches, one in Africa and the other in Eurasia. This was a medium-size animal, longer than it was tall, with a long tail and a fairly brushy coat. By about 30 to 40 million years ago Miacis had evolved into the first true dog-namely, Cynodictis. Miacis did not leave direct descendants, but doglike canids evolved from it. It is called Miacis, the genus that became the ancestor of the animals known today as canids: dogs, jackals, wolves, and foxes. Paleontologists and archaeologists have determined that about 60 million years ago a small mammal, rather like a weasel, lived in the environs of what are now parts of Asia. In ancient Egypt during the days of the pharaohs, dogs were considered to be sacred. In some areas of the world, dogs are used as guards or beasts of burden or even for food, whereas in the United States and Europe dogs are protected and admired. Western civilization has given the relationship between human and dog great importance, but, in some of the developing nations and in many areas of Asia, dogs are not held in the same esteem. Characteristics of loyalty, friendship, protectiveness, and affection have earned dogs an important position in Western society, and in the United States and Europe the care and feeding of dogs has become a multibillion-dollar business.
