In my understanding, one other reason for the Adam and the animals narrative is the subtext of anti-beastiality that the reader is supposed to discern, none of the animals was fit for a mate.

The naming by Adam is an EXAMPLE of him exercising authority of the animals that God gave to both the man and the woman.

Gen 2:19

Now out of the ground the LORD God had formed every beast of the field and every bird of the heavens and brought them to the man to see what he would call them. And whatever the man called every living creature, that was its name.

If you study the wording, one sees that there is NO command from God to name the animals, this is because the authority to do so is ALREADY in the command from Gen 1.
