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.

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.

always a good idea. like a sharp stick. fire. and of course the pizza oven.

Interesting article and difficult to imagine what it was like around 2.9 million years ago.

Way cool!
