'Humorous and accessible but never trivial... full of entertainment and insight' SUSAN QUILLIAM, co-author of The Joy of Sex How did sex begin? How did it evolve to be so varied in humans? What might sex look like in the future? The Shortest History of Sex traces the long evolution of human sexuality from the first microscopic couplings two billion years ago to today's somewhat baffling array of passions, impulses and fetishes. From the basic underlying chemistry to the tortuous complexities of the 21st-century human, David Baker lifts the lid on one of nature's primary forces. This is an erudite and entertaining book that tackles large questions with humour and insight – an essential guide for the curious reader.
