Evolution is real but there is some circumstance where evolution is not valid and to get to the bottom of this we need more than the scientists knowledge (because only the Person that creates the earth and the things that abide in it tell us the fact) because some aspect of their understanding about the earth and human creation can be misleading.
Back to the question, are humans superior forever? Yes, because they are created in God's image and this is the reason why satan was jealous.
