What’s it about?
The author here discusses several of the various concepts for defining species and the reasons why scientists would use one over another.
Why does it matter?
There are multiple species concepts, but they don’t all work in every situation. This will help explain why some researchers prefer one over another.
Why did I read this?
I was interested in the discussion of the various species concepts. In the end, this proved to be a rather lackluster summary of some of the commonly used species concepts.
