Kanzi the genius Bonobo can speak sign language, assign words to his favorite items, and can now create relatively sophisticated stone tools! 

The most remarkable aspect of the tools Kanzi created “is their resemblance to early hominid tools.”  Kanzi is able to crate and distinguish between wedges, choppers, scrapers and drills in order to get hard-to-access food.

These findings may help illuminate what defines modern human culture.

It is unclear whether these specific tools could be created by Bonobos in nature without any direct influence.  One thing is clear though, the potential is there!
