Research reveals ancient wolves in Ice Age Alaska were eating salmon, indicating early human-canine relationships in the Americas. The study, published in Science Advances, shows that dogs were fed salmon by humans around 12,000 years ago, pushing back the timeline of such relationships by 2,000 years.
Key Points
Ancient wolves in Ice Age Alaska were found to be eating salmon, indicating early human-canine relationships
Dogs were fed salmon by humans around 12,000 years ago, showing a level of care and investment in these animals
The study reshapes understanding of early human-canine relationships, suggesting a complex process of dog domestication
Pros
Reveals new insights into the timeline of human-canine relationships in the Americas
Demonstrates collaborative research between scientists and Indigenous communities
Highlights the deep historical roots of the modern Arctic tradition of close human-dog partnerships
Cons
Limitations in DNA analysis for definitively identifying ancient remains as wolf or dog
Small sample size of specimens compared to the vast time period studied
Challenges in dating specimens that had consumed marine foods like salmon
