Ancient humans living in what is now Alaska formed close relationships with wolves and dogs during the last Ice Age, new analysis suggests. Using bones unearthed across Alaska, researchers found that dogs and wolves lived alongside people more than 12,000 years ago, far earlier than previously thought. Some of the animals shared genetic similarities with European wolves, indicating they may be related to canines that came with human settlers across the Bering Strait, around 20,000 years ago. Others ate diets rich in salmon — which humans almost undoubtedly caught for them. While the exact relationship between the humans and canines is unclear, the fact that the animals ate salmon all year round, instead of seasonally, suggests a level of care modern pet owners might identify with. |
