Why does aging exist? Why, when we look about the world, can we only find two defensible examples of an immortal species, the hydra and the jellyfish Turritopsis dohrnii? There are a few other species that might be immortal, but the evidence is fairly shaky in near all cases, meaning that it is more of a challenge than is usually the case to show aging, or the data is sparse.
