Among the farm animals whose lives have become entwined with people, horses were a late addition. Dogs were the first animal friends of humans — wolves that scavenged for food among garbage piles and turned docile about 15,000 years ago, or possibly much earlier. Cattle, chickens and pigs were domesticated by people in different parts of the world between 8,000 and 11,000 years ago. It was only about 5,500 years ago that people in Central Asia started catching and keeping wild horses for meat and milk. Riding horses came later.
