>>Maybe I'm misunderstanding part of the study. It looks to me like they conclude there is in fact is a low genetic difference (ie, all the populations are closely related.) No surprise there, since all the circumstantial evidence points to the Hurricane theory; however, don't the authors also say that this low genetic difference could be because of the limited gene pool of captive bred pythons? If that's the case, what's the point? Was the DNA of captive pythons done for comparison?

They studied the genetics to see if they had four distinct and genetically different populations. It seems they do not, but that is what they wanted to learn.

The significance is if they had four gentically distinct populations, then perhaps different management needs would be found for each.

Before they blame a limited gene pool in captivity, they should go to bob clarks place and that of others to see how limited the captive gene pool is.
