The history of sex is as old as life itself, and no less complex and mysterious. Despite centuries of research, there is still room for sensationalism in this area. Australian scientist John Long has made a landmark discovery in the field of sexual evolution by deciphering the fossil record and reconstructing a detailed history of sex relations in nature spanning 400 million years. In a lively and entertaining presentation of deeply scientific facts, in his book he talks about the sex life of the oldest fish - the first species to have sexual reproduction, the unusual mating habits of arthropods, turtles and the stunning features of the super-sexy male Argentine duck. Readers can expect revelations about animal reproduction: the intimate complexities of romantic dinosaurs, gay penguins and ostriches, necrophiliac snakes, and the connection between the genitals of ancient sharks and our own sexual anatomy.
