You assume 'correctness of evolution' -- which is logically indefensible to begin with. That is what is being debated.
Hav it your way, but you belong on the religion threads, not science threads.
The argument is not about whether or not evolution is correct or plausible, but whether or not the classical Darwinian dynamic is the primary cause of speciation. Evolution is not a biological concept, but a mathematical one. Evolution is a basic systems dynamic. Biological evolution is just a particular expression of the mathematics.
There is no doubt as to whether or not biological evolution exists, since it is a mathematical necessity and evident in any case. The question is whether or not that dynamic is the primary mechanism of speciation. The argument is not about its correctness, only its scope in this particular instance.
