As you read these words, Planet Earth teems with trillions of life-forms, each going about their own business; eating, reproducing, thriving . . . Yet, why is death such a universal companion to life on Earth? Why haven't animals evolved to break free of its shackles?In this paradigm-shifting exploration of death, Jules Howard attempts to shed evolutionary light on one of our biggest and most unshakeable taboos. Encountering some of the world's oldest animals, and meeting the scientists attempting to unravel their mysteries, Howard also comes face-to-face with evolution's outliers; the animals that may one day avoid death altogether.Written in his familiar engaging and humorous style, Death on Earth's journey ends with the inevitable question: can we ever become immortal? And if we could, would we really want to?
