Ostrich eggs are more than just large; they’ve been used by ancient humans in surprising ways, even as writing surfaces. A recent study published in PLOS One explored 112 pieces of ostrich eggshell, dating back over 60,000 years, from southern Africa. Researchers noted unusual markings on these eggshells that hinted at a deep understanding of geometry among prehistoric people.
Silvia Ferrara, a historian from the University of Bologna, stated that these markings showed intentional designs, not random doodles. “These people organized their lines based on clear geometric principles—like parallelism and grids,” she explained in a statement.
This isn’t the first time ostrich eggshells have caught researchers’ attention. Back in 2020, a study from the University of Michigan suggested that hunter-gatherers made beads from these eggshells and gave them as gifts to loved ones about 33,000 years ago. Earlier, in 2010, engravings had been noted on eggshells, and some researchers had tried to categorize them by geometric features. However, the recent study was aimed at uncovering whether these patterns reflected cognitive abilities in early humans.
To dive deeper, the researchers meticulously reconstructed the eggshell engravings, examining angles, parallel lines, and repeating shapes. They found that over 80% of the designs showed clear spatial patterns. Simpler patterns had right angles, while the more complex ones displayed a grasp of transformations. Ferrara remarked, “These engravings show a mastery of geometric relationships.”
The analysis suggests that ancient humans could create visual designs following specific rules, hinting at the emergence of abstract thinking. However, the researchers are careful not to jump to conclusions about the meaning of these engravings since we can’t ask the original artists what they intended.
This study opens up intriguing discussions about how ancient humans interacted with their environment and expressed creativity. If history teaches us anything, it’s that our enjoyment of patterns and geometry likely has deep, ancient roots. As art and math enthusiast, it’s fascinating to think that our appreciation for well-structured designs might trace back to these very eggshells.
