Margulis, a noted evolutionary biologist, and coauthor Sagan use a metaphorical striptease and remove layers of human sexual development to reveal its evolutionary origins. Citing authoritative sources, they present new information regarding sperm competition, sexual anatomy, female orgasm, the family life of early humans, promiscuity, jealousy, and more. Margulis and Sagan explore the evolutionary roots of psychoanalytical sexual theories and pathologies, though they admit risking criticism with this approach. A welcome extension of their Microcosmos: Four Billion Years of Microbial Evolution ( LJ 6/15/86), this book offers the lay reader fascinating insights into the sexual ancestry that abides within us and the competitive forces that have molded us into our uniqueness. Highly recommended.
