Ring species debunks the definition of species being organisms that can reproduce with each other. That is what I was claiming ring species debunked. I was not claiming that ring species debunked evolution. Please pay attention.
Yet scientists still debate on the definition of species, and I don't see the logic behind concluding that just because organism A can no longer reproduce with organism B that therefore all life on the planet originated from a common ancestor.
Ring species, where species A can breed with species B, species B can breed with species C, but species A cannot breed with species C. That would mean that A and C are both the same and not the same species. It's a paradox.
Where did I say I was ignoring observations? Just because I reject some interpretations doesn't mean I reject the observations they were based on.
What exactly do you mean by this post?
