What is discussed here is a DEVELOPMENTAL process, not an EVOLUTIONARY process, i.e. it happens within the lifetime of an individual.
I agree with this. However, the OP is looking at something like Gerald Edelman's theory of consciousness, which Edelman refers to as
neural Darwinism. See, also, the
Wikipedia entry.
Evolution is a property of populations and species - not individuals.
Neural Darwinism looks at the brain as a population of neurons.
Personally, I'm skeptical of neural Darwinism as an account of human consciousness. But it is out there as a theory, and it is my impression that it is what the OP is wanting to discuss.
