How did the dog become domesticated???????
About 12,000 years ago hunter-gatherers in what is now Israel placed a body in a grave with its hand cradling a pup. Whether it was a dog or a wolf can’t be known. Either way, the burial is among the earliest fossil evidence of the dog’s domestication. Scientists know the process was under way by about 14,000 years ago but do not agree on why. Some argue that humans adopted wolf pups and that natural selection favored those less aggressive and better at begging for food. Others say dogs domesticated themselves by adapting to a new niche—human refuse dumps. Scavenging canids that were less likely to flee from people survived in this niche, and succeeding generations became increasingly tame. According to biologist Raymond Coppinger: “All that was selected for was that one trait—the ability to eat in proximity to people.” At the molecular level not much changed at all: The DNA makeup of wolves and dogs is almost identical.
