you see a lot of that with ancient greek philosophy, where it actively held back human understanding until someone in the middle ages finally called bull**** on it. you don't want to know what the greek philosophers thought about biology...
And indeed, the very mentality you have there ("but you can't prove it unless you claim to know everything!") is a large reason why flawed and incorrect ideas persist for longer than they should, despite evidence to the contrary. usually, most people are too busy slaving, fighting, or dying to think too long on it. I for one am not an expert in anything, and a lot of biology is guesswork (didn't I say that lol)? That is something entirely different from believing that the theory of Darwinian natural selction is invalid in entirety (patently false because of observational and experimental evidence that supports it within reason), and then that is something completely different from the horse**** ideas idiots get in their heads ever since they latched on to Darwin's theory to justify good ol' racism and human ignorance.
The theory of evolution can be seen in practice because living things are still adapting, and genetic traits can be selected for in a controlled environment. Also, you can notice genetic traits that would only become favorable if humans, for instance, domesticated cows and developed a tolerance for lactose. As I said, nature is dumb, and "natural selection" as much as idiots try not to think about it, is a messy process which moves very, very, very slowly. Using an appeal to nature argument is something that can be easily debunked and I'm not going to waste my time, only reiterate that if someone who still uses that argument is a ****wit.
