A dazzling follow-up to Life as told by a Sapiens to a Neanderthal. ‘We would love to discover that each species has a biological clock in its cells, because, if that clock existed and if we were able to find it, perhaps we could stop it and thus become eternal,’ Arsuaga tells Millás in this book, in which science is intertwined with literature. The paleontologist reveals essential aspects of our existence to the writer, and debates the advisability of transmitting his random vision of life to a dieting Millás, who discovers that old age is a country in which he still feels like a foreigner.After the extraordinary international reception of Life as told by a Sapiens to a Neanderthal, the most brilliant double act in Spanish literature once again dazzle the reader by addressing topics such as death and eternity, longevity, disease, ageing, natural selection, programmed death, and survival. Here you will find humour, biology, nature, life, a lot of life ... and two fascinating characters, the Sapiens and the Neanderthal, who surprise us on every page with their sharp reflections on how evolution has treated us as a species.And also as individuals.
