Sforno on Genesis 2:19/ספורנו על בראשית ב׳:י״ט

1ויצר ה' אלוקים מן האדמה כל חית השדה, G’d now provided these creatures with their final shape, putting the “finishing touches” on them, so to speak. At that stage of the earth’s condition, the original product which the earth had produced, not based on seed which contains all the genetic material in microscopic form, was not adequate to produce the final product without input by G’d, personally.

2ויבא אל האדם, in order for man to realise there was a need for an additional phenomenon, seeing that amongst the existing ones none met his need for a partner.

3לראות מה יקרא לו, so that he would see which name would be appropriate for each creature, based on the specific tasks they performed in the universe.

4נפש חיה הוא שמו, its name would provide all of us with a clue as to its function in G’d’s scheme of things. The essence of each animal, נפש, would be revealed by its activity on earth.
