Did humans truly domesticate dogs?

Though archaeology can help us pin down the when and where of dog domestication (current thinking is that it happened at least 15,000 years ago in Europe, Asia, or both), bones are mostly silent on the how and the why of this story. By studying other canids like foxes and wolves, and by analyzing dog genes, behavior, and brains—their sweet, friendly, trusting brains—researchers are developing new ideas about how the big bad wolf became the dear little dog.
