Philo Judaeus De Opificio Mundi 148

And with great beauty Moses has attributed the giving of names to the different animals to the first created man, for it is a work of wisdom and indicative of royal authority, and man was full of intuitive wisdom and self-taught, having been created by the grace of God, and, moreover, was a king. And it is proper for a ruler to give names to each of his subjects. And, as was very natural, the power of domination was excessive in that first-created man, whom God formed with great care and thought worthy of the second rank in the creation, making him his own viceroy and the ruler of all other creatures. Since even those who have been born so many generations afterwards, when the race is becoming weakened by reason of the long intervals of time that have elapsed since the beginning of the world, do still exert the same power over the irrational beasts, preserving as it were a spark of the dominion and power which has been handed down to them by succession from their first ancestor.
