"Like all science stories, this one begins with wonder." That's how Babel's Dawn the book starts. I''m quoting it because a dispute has popped up in the comments section on how science works and what sorts of questions are best asked. I was thinking one way, then another about my response and then I remembered how I began my manuscript and I thought, oh, yeah, wonder. There are lots of things to wonder about language: How did it begin? Is it really different from other forms of animal communication? How do words get meaning? What's a verb? Why do children learn to speak so easily while other animals don't learn it at all? Why can users ignore some rules and still be understood?
