Couple of questions wrt to this:
Evolution can only optimize over our learning process and reward circuitry, not directly over our values or cognition. Moreover, robust alignment to IGF requires that you even have a concept of IGF in the first place. Ancestral humans never developed such a concept, so it was never useful for evolution to select for reward circuitry that would cause humans to form values around the IGF concept.
Another example may be lactose tolerance. First you need animal husbandry and dairy production, then you get selective pressure favoring those who can reliably process lactose, without the "concept of husbandry" there's no way for the optimizer to select for it.
