Archaeologists in Israel have unearthed 10 "extremely rare" prehistoric stone hand axes that were crafted to deliberately include geological features, including fossils and geodes, a new study finds.
The hand axes were probably made by Homo erectus between 500,000 and 200,000 years ago, likely because our human ancestors thought these objects were imbued with potency and cosmic significance, the study researchers suggested, although others argue further evidence would benefit the study.
