The Dog's Evolution


There are approximately 500 million domestic dogs in the world, and they are all related. The gray wolf, from which every type and breed of dog has descended, is at the root of their evolutionary tree. In terms of DNA, the distinction between wolf and dog is infinitesimal, as geneticists have found. While natural selection has contributed to some of the differences that distinguish one dog from another, human influence has had a much greater impact. It is possible to say that all of the hundreds of modern dogs that exist today are man-made.


THE DOG'S DAWN


The dog's origins as a wolf and subsequent transformation into a domestic companion can be traced back to early hunter-gatherer settlements. Wolves would scavenge among the litter around the camp site, providing a valuable source of hides and meat to these primitive groups. Should an intruder or outsider approach the camp, the wolves may unintentionally raise the alarm. Humans in general appear to be programmed to adopt animals, either as playmates or status symbols, which may explain why wolves were first introduced into the domestic circle. Perhaps a small furry wolf cub appealed to our forefathers as much as a small furry wolf cub would appeal to us today.




The human and dog relationship was born when it was realized that a tame wolf with a sharp nose and strong instincts would be an asset as a hunting companion. If, as appears to be the case, the most promising animals were chosen for this purpose, it would have been the start of a selection process for desirable characteristics that is still used by dog breeders today. Domestication of wolves is unlikely to have occurred in a single instance, but rather in multiple instances over time and in widely separated areas. Archeological evidence of dogs buried alongside humans has been discovered in places as diverse as the Middle East (which is believed to be one of the earliest sites of domestication), China, Germany, and the United States.



The oldest of these remains was recently dated at around 14,000 years old, but research into a fossilized canine skull discovered in Siberia published in 2011 suggests that dogs were domesticated as long as 30,000 years ago. When wolves were domesticated, their appearance and temperament began to change, regardless of when or where it occurred. Crossbreeding between different dog populations resulted in the emergence of new types of canids, which increased their diversity. Some hunter-gatherer tribes were isolated for generations due to food scarcity and climatic conditions, but others were migratory, which meant that the dogs trailing them encountered and mated with each other.
