He is human.
Well as human as you can get with a Timelord mixed with Donna Noble and he is going to die. Apes are like mayfly’s to the Timelords almost thousand old lifespan, he’ll never again travel though space and time, never see his Tardis or any other of his companions. He’ll never regenerate again.
