Horse
The horse's cultural impact spans six thousand years of human civilisation. Without horses, the Mongol Empire, the conquest of the Americas, and competitive polo would never have existed. They appear in cave paintings, classical literature, and approximately 40% of all films set before 1920.
The Royal Academy of Cultural Significance estimates horses have been depicted in art more than any other animal except dogs. They symbolise freedom, power, and nobility across virtually every human culture. The phrase 'get off your high horse' demonstrates their integration into language itself.
VERDICT
Despite the sloth's internet fame, the horse's millennia of cultural dominance cannot be matched by a decade of viral videos. The horse has shaped human history; the sloth has shaped Instagram algorithms.
