Ice Age dice show early Native Americans may have understood probability

Ice Age dice unearthed in North America reveal that early Native Americans may have understood probability, a milestone that rewrites assumptions about prehistoric mathematical thinking. These carved bone artifacts, dated to over 10,000 years ago, show deliberate symmetry and scoring that suggest intentional randomization—not mere decoration. The dice's uniform facets indicate a grasp of equal likelihood, a concept not widely documented for another 8,000 years. Such precision challenges the narrative that complex numerical thinking emerged only with agriculture, placing these hunter-gatherers among the early innovators of probability theory.
