Heterogametic Sex Hypothesis

In mammals, including humans, sex is generally determined by the X and Y chromosomes. If a baby has a pair of X chromosomes, she’s a girl. If the baby inherits an X chromosome and a Y chromosome, he’s a boy. In birds, however, the situation is reversed. Female birds have a pair of unlike sex chromosomes while males have the like pair. (In this sort of sex-determination system, scientists use the letters W and Z, and talk about a ZW pair for female birds and a ZZ pair for males.) The “...

 19756 Gary Gygax Quote on Women in Wargaming

“I have been accused of being a nasty old sexist-male-Chauvinist-pig, for the wording in D&D isn’t what it should be. There should be more emphasis on the female role, more non-gendered names, and so forth. I thought perhaps these folks were right and considered adding women in the ‘Raping and Pillaging[’] section, in the ‘Whores and Tavern Wenches’ chapter, the special magical part dealing with ‘Hags and Crones’, and thought perhaps of adding an appendix on ‘Medieval Ha...

 Sex Makes Life and Should Not Be Shunned

If there is a perverse man who could take offense at the praise that I give to the most noble and universal of passions, I would evoke Nature before him, I would make it speak, and Nature would say to him: why do you blush to hear the word pleasure pronounced, when you do not blush to indulge in its temptations under the cover of night? Are you ignorant of its purpose and of what you owe it? Do you believe that your mother would have imperiled her life to give you yours if I had not attached ...

 The Symbionts

As the epochs passed, the two species molded one another to form a well-integrated union. The little arachnoid, no bigger than a chimpanzee, rode in a snug hollow behind the great "fish's" skull, his back being stream-lined with the contours of the larger creature. The tentacles of the ichthyoid were specialized for large-scale manipulation, those of the arachnoid for minute work. A biochemical interdependence also evolved. Through a membrane in the ichthyoid's pouch an exchange of endocrine ...

 Human Biology and Monarchy

Luard calls the first of his ages, which ran from 1400 to 1559, the Age of Dynasties. In this epoch, royal “houses,” or extended coalitions based on kinship, vied for control of European turfs. A little biology shows why the idea of basing leadership on inheritance is a recipe for endless wars of succession. Rulers always face the dilemma of how to reconcile their thirst for everlasting power with an awareness of their own mortality. A natural solution is to designate an offspring, usual...
