Bonobos use a kind of syntax once thought to be unique to humans

Reinforcing my strongly held belief that what fundamentally sets humans apart isn't spoken language, or tools, or any of that, but rather the fact we write down what we know, then make those writings available to future generations to build on. We're a species distinguished from all others by our information-archival and -dissemination practices. We're an archivist species, a librarian species. Homo archivum. In my opinion.

I’d love for that to be true, but our species dates back 300,000 years, while writing started only 3,000 years ago. Writing is definitely not a fundamental trait of our species, although once we got this update, things started moving quickly.
