5,000 years ago, humans ferried wild wolves by boat to a remote Swedish island, where scientists say they fed and possibly cared for them long before dogs existed

Ancient canid remains unearthed on Stora Karlsö reveal pure wolves. These wolves were transported by prehistoric people, not swimming across the sea. Their diet of marine proteins indicates human care and shared resources. Skeletal evidence suggests managed populations and human intervention. This discovery challenges previous understandings of early wolf domestication processes.
