Male genitalia in Drosophila exemplify strikingly rapid and divergent evolution, whereas female genitalia are relatively invariable. Whereas precopulatory and post-copulatory sexual selection has been invoked to explain this trend, the functional significance of genital structures during copulation remains obscure. We used time-sequence analysis to study the functional significance of external genitalic structures during the course of copulation, between D. This functional analysis has provided new information that reveals the importance of male-driven copulatory mechanics and strategies in the rapid diversification of genitalia.

But even if there were thousands of science-humor writers, she would be the sidesplitting favorite. Of course, she chooses good subjects: cadavers in Stiff , ghosts in Spook , and now a genuinely fertile topic in Bonk. As Roach points out, scientists studying sex are often treated with disdain, as though there is something inherently suspicious about the enterprise. Yet through understanding the anatomy, physiology, and psychology of sexual response, scientists can help us toward greater marital and nonmarital happiness.
Bonk : the curious coupling of science and sex / Mary Roach.
It follows the winding history of science and its exploration of human sexuality, going back as far as Aristotle and finally ending with recent discoveries about the origination and anatomy of the female orgasm. Throughout, Mary Roach provides a humorous and often very personal view—both as a participant and observer—of humans, scientists, animals, and sex machines. Of the book's numerous accounts, Roach discusses artificial insemination of sows in Denmark, the notorious history of sex machines, as well as much discussion and commentary on Kinsey 's notorious attic sex experiments. Her footnotes provide additional humor; as in a sentence which includes several DSM diagnoses listed as acronyms she adds "And from HAFD hyperactive acronym formation disorder ".
