Worlds Smartest Horse Passes Self-Awareness Test Lukas, the World’s Smartest Horse (according to the World Records Academy) and Guinness World Record Holder (“Most numbers correctly identified by a horse in one minute: 19”), has joined an elite group: those with the capacity for self-awareness. He has proven that he is able to recognize his own reflection in a mirror as an image of himself. To date, only humans (after the age of eighteen months), great apes, bottlenose dolphins, orcas, elephants and European magpies have successfully passed this test. For this experiment, Karen Murdock, Lukas’ owner/trainer, utilized the mirror test, developed by Gordon Gallup in 1970 (based on observations by Charles Darwin). It determines whether an animal can recognize its own reflection in a mirror as an image of itself.
