Ka ka ka ka ka ka ka ka

Previous crow stuff has been covered by Jerry Coyne himself. This in turn stimulates lot of debate on what constitutes a species. Fortunately, most people agree that understanding the genetics is more important and relevant than fighting over the definition of species. 

Like the title of this post, the call of a crow can be written as "ka ka ka ka ka" or "kaw kaw kaw kaw" or "Caw caw caw caw". They are all trying to capture the same thing. As long as the underlying genetics is well understood, it should be ok to not worry about the definition for now. Hopefully, over time our understanding of genetics will be so good that we may even come up with a single definition that most of us can agree on.
