Well, the Thu'um was around before the mortal races could use it, the magic was just "locked" so to speak. Kynareth unlocked it and allowed for mortals to tap into that mysticism. Akatosh crafted the dragonborn, or dragon blood, which were able to naturally use and absorb Thu'um energies, without extra study or care. She gave certain mortal familes the power of the Dov and that is what caused this. The Septim line is a perfect example of such, and they actually had a very special and unique relationship with Akatosh. Their blood not only help small innate powers from the Dov, but via the Amulet of Kings was able to stop the powers of Oblivion from flooding into the realm of Nirn and Mundus.
