How Did Humans Start Breeding Dogs
When dogs reproduce without such human intervention, their offspring's characteristics are determined by natural selection, while dog breeding refers specifically to the artificial selection of dogs, in which dogs are intentionally bred by their owners. Before people actually bred dogs, the most likely scenario is that certain wolves evolved to be more human friendly, so they could feed off the scraps left behind by people without having the humans bother with killing them or chasing them off.
“over time, humans have genetically manipulated their dna to create a dog specifically suited for whatever it is they want to accomplish,” said robert cole, a certified dog behavior trainer.
How did humans start breeding dogs. One that did not bark was simply disposed of as being useless. Dogs and canines were domesticated between 10,000 and 35,000 years ago through selective breeding, suggesting the earliest dogs presumably arose once we, humans, were still searching and gathering, way before the appearance of agriculture. By looking at the rates of change to the dna from the oldest specimen, scientists were able to place the timing of the domestication of dogs to between 20,000 and 40,000 years ago.
Here is how it works. By studying the rates of change to the dna from the specimen they collected, scientists timed the domestication of dogs to between 20,000 and 40,000 years ago. Thus, early humans began a selective breeding program to create such dogs.
The society for the prevention of cruelty to animals is formed in britain, giving birth to an organized welfare group for dogs. It is truly amazing that the crops domesticated thousands of years ago are still with us today feeding 6 billion individuals. But if they all share a common ancestor, why do toy poodles and great danes seem.
The domestication of animals is based on an ancient contract, with benefits on both sides, between man and the ancestors of the breeds familiar to us today. This sets the foundation for a shift in people’s perspective about dogs. For example, many experts agree that dogs started to separate from wolves starting around 16,000 years before present in southeastern asia.

The earliest known evidence of a domesticated dog is a jawbone found in a cave. History did not wait for our fancy (and amazing) articles to understand how to breed dogs. When you breed dogs to look different or act differently, like in your example, you are basically changing the genetic code of that group of dogs.
They might have been similar in. So, according to derr, a certain peculiarity—for example, a curly tail—first arises by mutation. Dogs were companions to humans long before written history, but being a guardian and a hunting partner is quite different to being a pet.
