Similar thing with hang gliders but no right feathers in of all things

It's a spear because they sharpen it with their teeth

There is a video of a golf cart driving gorilla or orangutan. So they are very aware of their surroundings too they can learn a lot. Maybe in a few million years they start to use language as well or some other animal. I wish complex language wasn't just a human thing than we would learn that religion is bs. Etc..

They seem smarter

I would like to buy you

Chimpy charms?

Ok Green Goblin lmao

*sharpens a stick* 😎😎😎

Well, they did break off a branch and stab a smaller monkey with it, or attempt to do so.

Also for something to be a "spear" it doesn't necessarily need to be sharp. You could spear something with a blunt stick. Besides, it's vastly different in the fact that it's a larger stick being actively used to jab a small animal, rather than a small twig that sits in a hole for a few seconds.

It likely looks like that because it was repeatedly jammed into the tree. They don't get caught on camera doing it that often, but there's footage of them making the spears. They bite the tip and apply lateral pressure to the stick making it snap in an oblique angle creating a sharp, splinter-like point.

@@habibishapur Now THAT is interesting.

​​​@@SandyRiverBluealso of note is that chimpansees do come back to their tools(not the sticks tho) or keep them around for later use. There is even primate archeology, in which they find thousand year old hammer and anvil stones used to crush nuts over and over, creating a very crude mortar and pesstle over time due to wear. This is quite special as almost every animal that uses tools use tools of opportunity: they face a problem, find a tool, use tool, succes and forget about tool. If they know that keeping the tools around is handy because they might be handy later this might mean they are on their way to make more recognizable tools. When the conditions are set it might create a feedback loop: if i keep tool i can use later. Tool works better over time i want to keep tool. They get dedicated tools for different jobs. Seeing function and uses, seeing design even maybe evolves. Those are crucial attributes for making more complicated or compound technologies. With the bushbaby spears a similar feedback loop might appear: if i make stick sharper it pokes better. If i make stick bigger i can poke bigger things. A real spear is born then.

They need to learn how to control fire and cook meat, before making even anything vaguely resemble a string.
