From People.com:
Two ancient wolves discovered inside a cave on a tiny Swedish island are raising new questions about how closely humans and wolves may have lived together thousands of years ago.
In a study published in the Proceedings of the National Academy of Sciences, researchers analyzed the remains of two canids found in Stora Förvar Cave on Stora Karlsö, a small island in the Baltic Sea. Genetic testing revealed the animals were wolves dating back roughly 3,000 to 5,000 years — but how they ended up on the isolated island is the mystery.
