Collecting Keepsakes May Have Aided Autobiographical Memory Evolution
Summarized from The Jerusalem Post by baba
An Israeli study suggests early humans collected objects as keepsakes to develop autobiographical memory, potentially starting 500,000 years ago. Researchers examined artifacts from sites in Israel, proposing that items like colorful pebbles and uniquely decorated tools served as personal mementos. This practice may have helped early humans remember locations and experiences, influencing the evolution of memory functions in the brain. The study hypothesizes that environmental changes might have driven this behavior, with collected objects acting as "external memory devices."
