Overview
- A peer-reviewed PNAS study reports 3,000–5,000-year-old wolf remains from Stora Förvar cave on Sweden's Stora Karlsö.
- The 2.5 km² island has no native land mammals, indicating the animals were transported by people, likely by boat.
- DNA from two canid bones confirms they were wolves with no detectable dog ancestry.
- Isotopic analysis shows a seal- and fish-rich diet that mirrors human food on the island, implying provisioning or close cohabitation.
- One Bronze Age wolf survived a severe limb injury, and one genome shows unusually low diversity, patterns consistent with isolation or possible human management.
