Imagine, for a moment, a world without apes. No chimpanzees knuckle-walking through the fading forests of Gombe. No gorillas staring with unnervingly human eyes from the misty volcanoes of Rwanda. No orangutans drifting like rusty ghosts through the crumbling canopies of Borneo. Now, extend the thought experiment: a world not merely devoid of our closest biological cousins, but a world that has consciously, proudly declared itself anthropoid free .

Of course, a skeptic—a sentimentalist, a biologist, a person with a functioning moral compass—might object. They would point out that studying chimpanzees taught us that warfare is not an invention of civilization, but a deep evolutionary inheritance; that observing gorillas taught us that gentleness is not a failure of masculinity; that decoding the bonobo’s matriarchal, conflict-dissolving society offers a living alternative to our own violent hierarchies. They would say that to eliminate the anthropoids is not to free ourselves, but to amputate the only mirror that shows us what we truly are: a slightly more articulate ape, still smelling of the forest, still capable of both shattering cruelty and astonishing tenderness.

And here lies the twist. The “anthropoid free” world is not a future we can achieve by hunting or habitat destruction—though we are, tragically, working hard on that. It is a philosophical thought experiment that reveals the opposite of its intention. To wish for a world without apes is to wish for a world without self-knowledge. For what is an ape, after all? It is not a rival. It is a relative. It is the awkward uncle at the family reunion, the one who picks his nose and throws his feces, yet whose resemblance to your father is so strong it makes your heart ache.

The problem with anthropoids is not that they exist, but that they mirror . A chimpanzee using a twig to fish for termites is not merely a clever animal; it is a crack in the philosophical fortress of human exceptionalism. A gorilla signing “I am sad” in American Sign Language is not a parlor trick; it is a lawsuit against the very concept of the soul as a human monopoly. The anthropoid is a living, breathing, knuckle-walking refutation of our most cherished fictions: that tool use, language, self-awareness, culture, and grief are ours alone. To be “anthropoid free” would be to scrub the looking glass clean.

Without the great apes, the debates that paralyze modern bioethics evaporate. No more hand-wringing over invasive medical testing on creatures who recognize themselves in mirrors. No more awkward courtroom battles over whether a bonobo named Kanzi deserves habeas corpus. No more uncomfortable Sunday school questions: “If chimpanzees have 99% of our DNA, why didn’t they build the Sistine Chapel?” The answer, in an anthropoid-free world, is simple: because they were never there. The ladder of being becomes a smooth, unbroken pole from sponge to human, with no disconcerting, hairy faces peering down from the rung just below.

The economic benefits, too, would be staggering. Vast tracts of Central African and Southeast Asian rainforest, currently patrolled by underfunded and outgunned park rangers protecting apes from poachers, could be reclassified. Timber, palm oil, and coltan mining—the minerals in your smartphone—could proceed without the awkward obstacle of an endangered species’ habitat. The billions spent on sanctuaries, anti-poaching drones, and ecotourism logistics could be redirected into, say, colonizing Mars. After all, you can’t trip over a mountain gorilla on the dusty plains of Ares Vallis.

Culturally, the relief would be profound. No more conflicted feelings at the zoo, watching an orangutan smoke a cigarette thrown by a tourist and recognizing the boredom in its eyes. No more queasy sense of trespass when watching a nature documentary’s tender scene of a mother chimp grooming her daughter. No more Planet of the Apes to trouble our sleep with visions of a justly conquered future. Without anthropoids, our myths remain clean: the clever fox, the loyal dog, the noble lion—none of them stare back with our eyes. We could return to a pre-Darwinian comfort, a solipsistic Eden where we are truly, utterly alone at the top.
