DiscoveriesStone Age objects identified as nutcrackers, dating to 780,000 years ago, suggest that our early human ancestors spent at least part of their day cracking and eating nuts, according to a recent report by a team of Israeli archaeologists.Researchers believe the 54 basalt and limestone stones, found at a site called Gesher Benot Ya'aqov that lies north of the Sea of Galilee in Israel, functioned as basic hammers and anvils.
This earliest known evidence that humans cracked nuts suggests that the user used one stone to bang a nut placed on the second, or "anvil" stone. Pits or concave depressions on the surface of several of the stones indicated signs of banging and wear.
Plant material from seven species of nuts was found at the site. The nuts included almonds, two types of pistachios, acorns, water chestnuts and nuts from a seeded fruit called the prickly water lily. All require shelling, and researchers think early humans ate these types of nuts.
