(University of California - Santa Cruz) Sexual reproduction in animals has been recognized since ancient times and used in the breeding of domesticated animals for more than 10,000 years. For most of that time, however, there was no intentional breeding of crop plants because people didn't think plants had sex. A new book, 'Flora Unveiled,' offers a deep history of perceptions about plant gender and sexuality, from the Paleolithic to the 19th century.
