^^^^ Hmm...
The corbicules have the same highly practical limb structure as the rest of their subphylum: six stumpy podicles for walking, two muscular dorsal tentacles for gross manipulations and two slender buccal tentacles by the mouth for fine manipulations. They spend most of their time in sprawling underground city-complexes, venturing to the surface to harvest vegetation to feed the subterranean metafungal gardens that provide them with nourishment. By some combination of luck and a broad general tendency toward cephalization common to many evolutionary lineages, Earth’s last intelligent species is also its most intellectually gifted; hatchlings barely out of creche are given fun little logic problems such as Fermat’s last theorem for their amusement, and a large majority of adult corbicules are involved in one or another field of intellectual endeavor. Being patient, long-lived, and not greatly addicted to collective stupidities, they have gone very far indeed.
Some eight thousand years back, a circle of radical young corbicule thinkers proposed the project of working out all the physical laws of the cosmos, starting from first principles. So unprecedented a suggestion sparked countless debates, publications, ceremonial dances, and professional duels in which elderly scholars killed themselves in order to cast unbearable opprobrium on their rivals. Still, it was far too delectable an intellectual challenge to be left unanswered, and the work has proceeded ever since. In the course of their researches, without placing any great importance on the fact, the best minds among the corbicules have proved conclusively that nuclear fusion, artificial intelligence, and interstellar migration were never practical options in the first place.
Being patient, long-lived, and not greatly addicted to collective stupidities, the corbicules have long since understood and accepted their eventual fate.
