The Nature of Sex
あらすじ・解説
A brilliantly engaging guide to the reproductive habits of creatures great and small. Narrated by the author, Dr. Carin Bondar.
In The Nature of Sex, 'biologist with a twist' Carin Bondar presents the fascinating diversity of the reproductive habits of the animal kingdom and, through approachable explanations and humorous examples, succeeds in making an eternally popular subject into a book of international appeal. Her web series of the same name attracted over 12 million views, and in this richly diverse book she examines the sexual strategies and reproductive structures of the hyena, earwig and guppy, among other creatures.
Dr. Bondar explains that until approximately 500 million years ago sex was a 'mere trickle of DNA', a thoughtless merging of cells. With the evolution of sexual organs as we know them, social hierarchies have also developed, dictated by the sexual dynamics between creatures of each species. She examines the mechanics of sexual intercourse between certain animals, describing differing tactics of seduction, from 'coercion' to 'titillation', showing images of different penises, and comparing the cost of reproductive cells in females (high) and males (low). She examines the violent methods used by some animals to inseminate females, from the bedbug's spiked, barbed penis to the 'ballistic' spiral-shaped penis of the duck. She then explores the probability that other animals experience pleasure from sex, based on observation of their behaviour related to choosing mates based on penis size or other pleasure-inducing appendages.
Finally, Dr. Bondar describes matriarchal animal societies, noting that when the female has the reproductive power, or 'penis power', she also possesses social dominance in the group.
Dr. Bondar reiterates that sex in the animal kingdom determines how males and females relate to each other and how their population will develop. Of course this extends to our own society as well, and her vividly written and scrupulously researched book encourages us all to think about sex - if not more frequently then certainly more profoundly.
