Again, you keep on saying "I don't think it's necessary", but that is merely a straw man. No one in evolutionary science has every claimed that improvements must be "necessary" in order to make sense. And, our ability to reason makes it much easier to hunt, grow food, provide shelter, etc. It separates us from every other species.This isn't really an argument. What is needed is a strong correlation between reason and evolutionary survival, especially speculative reason. Response to stimuli, for example, will often do just as well as reason. When we touch a hot stove and quickly withdraw our finger, we do not reason about this. We do it as a response to stimuli. It is hard to see why we couldn't survive just as easily by always relying on response to stimuli and not reason.
I don't think that it was necessary for proto- and early humans to have reliable cognitive faculties to survive. These faculties could be severely faulty and yet, if they still operated in a way that aided our survival, they could still allow us to survive well without reliable rational inference. There seems nothing in evolutionary theory alone to give us reason to think they are probably reliable. Besides, it is especially on speculative and abstract reason that naturalism and naturalistic evolution rely. It is even harder to see how the naturalistic evolutionary account can give a strong reason why we would develop reliable reason when it comes to speculative and abstract reasoning that went beyond the nonapparent aspects of our environment (its molecular structure and so on).
