So it seems that stone tools were more widely made than by merely the ancestors of homo sapiens.
Exactly! Ever watched a raven use tools? They do! How about parrots? YUP! But...back to the primates...I've said this before but will say it again....we never give early people enough credit! Think about the cave petroglyphs.
Although many animals use naturally occuring objects as temporary tools. Only Primates, not necessarily homo, have deliberately smashed and chipped away at stones, etc, in order to CREATE tools
Excellent.
Although other current primates use tools so the discovery should be corroborative and unsurprising.
About the pizza oven, it's well known that a Mesopotamian woman invented scissors one morning to cut the flat bread pizzas but by early afternoon had invented the first wheel for the pizzas and it just rolled on from there.
The Greeks thought all the flint knives and random stone tools were gifts from the gods just in case you needed a flint knife.
Sort of a divine UBI.
We have modern monkeys that use stone hammers to bust open nuts.
