New research spanning five continents and vastly different cultures -- from the steppes of Mongolia to the rainforests of the Pacific -- shows that hunting dogs and their owners cooperate, communicate and rely on each other in nearly identical ways, suggesting the relationship was forged in deep evolutionary time, perhaps 30,000 years ago.
