摘要
En 中文
Domestic dogs show socio-cognitive abilities that are not found in other species, including dogs' closest living relative, the wolf. From early on dogs are good at reading human gestures and pay attention to humans' eyes and voice. Two new studies suggest that a heritable component to dogs' social cognitive skills exists and that selection during domestication must have played a role in enhancing dogs' social cognitive skills.
