Humanity's Dual Response to Dogs and Wolves.

Dogs were first domesticated 31 000-41 000 years ago. Humanity has experienced ecological costs and benefits from interactions with dogs and wolves. We propose that humans inherited a dual response of attraction or aversion that expresses itself independently to domestic and wild canids. The dual response has had far-reaching consequences for the ecology and evolution of all three taxa, including today's global 'ecological paw print' of 1 billion dogs and recent eradications of wolves.
