Briffault’s Law

Briffault’s law states that the female, not the male, is the head of an animal family and determines all of its conditions. The law applies only to nonhuman animals, and not to humans.
Robert Briffault outlined his law in his book The Mothers, Vol. I. He applied the law to a variety of animals, including tigers, lions, zebras, gazelles, buffaloes, deer, monkeys, beavers, and birds. Briffault also briefly referenced humans to contrast their behavioral patterns from those of animals.
