There are usually two hormones in each species, the active principles rarely varying from one species to another within a given class. Thus oxytocin and arginine vasopressin have been chemically identified in five species of mammals belonging to the orders Primates, Artiodactyla, Perissodactyla and… CONTINUE READING
