Why is life the way it is? Bacteria evolved into complex life just once in four billion years of life on earth-and all complex life shares many strange properties from sex to ageing & death If life evolved on other planets would it be the same or completely different? In The Vital Question Nick Lane radically reframes evolutionary history putting forward a cogent solution to conundrums that have troubled scientists for decades The answer he argues lies in energy how all life on Earth lives off a voltage with the strength of a bolt of lightning In unravelling these scientific enigmas making sense of life's quirks Lane's explanation provides a solution to life's vital questions why are we as we are & why are we here at all? This is ground-breaking science in an accessible form in the tradition of Charles Darwin's The Origin of Species Richard Dawkins' The Selfish Gene & Jared Diamond's Guns Germs & Steel
