Why have humans collected crystals for 780,000 years? Chimpanzees may hold the answer
Archaeologists have discovered that early humans collected crystals 780,000 years ago, despite them having no functional utility. A new study suggests that chimpanzees share this innate attraction to crystals, indicating that the behavior may have deep evolutionary roots.
Why it matters
This research provides insight into the cognitive evolution of humans and our closest primate relatives.
Archaeologists have uncovered crystals at numerous sites containing Homo remains, suggesting that early human relatives deliberately collected these unusual stones as far back as 780,000 years ago. What makes this behavior so intriguing is that the crystals were not used as tools, weapons, or jewelry. So why were they considered worth keeping?
