We have the most intellect out of any animal, and we are still primates, so we don't expect some imaginative amount of intellect you think should be required for this factual evolution of consciousness.
They are all factually required for survival. You just refuse to address the issue or are totally ignorant of the reasons. Either way its a personal issue on your part for not understanding why conscious is factually required for survival
You don't really offer any kind of argument here.
You don't see how developing reliable rational faculties would help us survive in our environment? Wouldn't "understanding our immediate environment" help an individual or a population "survive in our environments", and wouldn't "develop[ing] reliable rational faculties" help an individual "understand [their] immediate environment" thus helping an individual or a population "survive in their environment", and better yet, reproduce?
It's not a matter of being required to do so.
Actually, the EAAN is a probabilistic version of the argument from reason. It basically relies on us needing good reasons to trust our cognitive faculties and evolutionary implying there is no clear relationship between our the development of our cognitive faculties and their reliability when it comes to abstract reason. So, perhaps to talk of requiring is a bit strong, but, yes, there does, it seems, have to be a clear relationship established between the reliability of our cognitive faculties and their evolutionary utility.
Anyway, surely that evolutionary speaking it is a matter of coping or surviving in our environment. I am not sure how proto- and early humans would require any sort of reliable abstract reasoning. Indeed, where does the need to cope with the challenges of our environment necessitate the development reliable cognitive faculties for abstract thought (of the kind that could formulate a naturalistic evolutionary explanation of consciousness and reason), or at least give us strong reasons for thinking that such a development would arise?
Indeed, as C. S. Lewis pointed out, there seems, evolutionary speaking, why reason need enter into the matter at all. Simple response to stimuli might just as easily get the job done.
