Elaine Morgan OBE, FRSL (7 November 1920 – 12 July 2013), was a Welsh writer for television and the author of several books on evolutionary anthropology. She advocated the aquatic ape hypothesis, which advocated as a corrective to what she saw as theories that purveyed gendered stereotypes and failed to account for women's role in human evolution adequately. The Descent of Woman, published in 1972, became an international bestseller, translated into ten languages. In 2016, she was named one of "the 50 greatest Welsh men and women of all time" in a press survey.
