9、e that dogs were once wolves and they were the first animal to be domesticated(馴養(yǎng)) by humans.They came into human lives some 15,000 years ago, before the dawn of agriculture. Beyond that, there is little agreement.The earliest bones found that are unquestionable dogs' and not wolves' date from 14,0
