Re: can or do breed
Gene isolation is gene isolation, no matter the reason.
​
This raises the (to me at least) slightly odd possibility that what had been two species could suddenly become one. If you have two groups that can breed together in the wild but don't only because of some physical barrier they are two species by this definition. If however the physical barrier is removed these two groups/species will be able to mix and breed and so become one species.
​
Is this just so unlikely/insignificant that it isn't worth bothering about ?
​
Confused ? You will be...

Off Topic for LDSdude
LDS - I don't know if it will help you get your topic about perfection advanced but I think the link you want is :
​
http://www.kiawahturtles.com/...Evolution%20of%20Turtles.htm
​
See - even on this site the non-creationists can be helpful
​
On the other hand I don't have a clue what your topic is about - maybe if Ned helps you advance it everything will become clear.

Re: While we're off topic
Cool - once I'd worked out what GaDNR meant (fortunately my twelve year old memory of living in the US came back to save me having to look it up ).
