Humans have a natural inclination to collect things, even if it may not have a clear evolutionary purpose. Whether it's stamps, comic books, or rare coins, the act of collecting reflects a level of cognitive ability and abstract thinking. The origins of this behavior can be traced back to our Neanderthal ancestors, as evidenced by artifacts found in a cave in Iberia, Spain. In a recent study published in the journal Quaternary, researchers discovered 15 small marine fossils in a cave system in Burgos, Spain. While some of these fossils showed signs of use as tools, others seemed to have no practical purpose. The fossils, dating back to over 39.8–54.6 thousand years ago, were not native to the cave's region, indicating that they were collected from distant locations. Previous research suggests that Neanderthals engaged in cultural rituals, including activities like ornamental crafting and cave art. It is likely that they also participated in collecting items that they found intriguing or special, similar to modern human behavior. The researchers speculate that Neanderthals may have collected these fossils for a variety of reasons, such as competition, cooperation, symbolism, or even for pleasure. Just like humans today, the act of collecting may have brought them joy or served a magical or religious purpose.
