yepper! I think there was actually several years of studies about 'evolving around the blight'. They called it hypovirulence. I cant remember the details but if you google it there should be some things about the AC.Trout 2003 said:... One would think that eventually it would evolve around the blight. I guess the issue is that a plant has to survive and reproduce in order to evolve.
And to take it to the next step, the blight does not want to kill the tree... because the blight will then lose its host and can not exist and dies. It just wants to live in symbiosis with the tree. so the blight evolves to not be so deadly but rather just a moderate infection. (or something like that)
