Stress Management Helped Wolves Become Dogs
From Scientific American:
The wolf relatives of modern-day dogs began the evolutionary process of becoming humans’ best friends more than 10,000 years ago. But despite more than a century of research, scientists still do not know the full story of how and why dog domestication occurred in the first place. Now a new study published on Thursday in Scientific Reports reveals genetic changes that may have allowed ancient dogs to feel comfortable around humans by lowering the stress levels the animals experienced in our presence.
