Chris,

You just made that way too easy LOL



For the sake of discussion, even though I agree with you in principle....



Is Intergradation really what is taking place here? Is this an example of two subspecies with expanding ranges that are coming together and providing gene flow? Or is this an example of a wide ranging species that exhibits geographic variation and is in the process of speciation?



The only reason I ask is because even though I (we) use the term intergrade, and generally accept it, it really has a very specific meaning, at least IMO, that can not accurately convey what is taking place with every population because of the multitude of different factors at play with various populations.



Or maybe I'm just making too much of the term "intergrade" and it "only" implies that the population exhibits traits from two generally recognized subspecies, and has no implications regarding mode of speciation? If so I'm still interested in your take on the getula population in Texas.
