Ancient Eggshells Reveal Early Abstract Thought | Science News

Ancient ostrich eggshells from southern Africa, some over 60,000 years old, reveal astonishingly complex geometric engravings—grids, parallel lines, and precise right angles—that defy randomness. A new study in PLOS One analyzed over a hundred fragments using advanced geometry and stats, finding that 80% follow consistent spatial layouts, including repeated patterns, rotations, and layered designs. This suggests early humans possessed sophisticated abstract thought, planning visual compositions before carving, hinting at deep-rooted human traits like pattern-making and meaning-creation that stretch back millennia.
