Depends what you mean by intelligence. Ravens and chimps are almost as good as humans at causal reasoning, ie. correlating and inferring causes and effects from observations. This seems to fall under a typical understanding of "intelligence".

Where we differ is that we can communicate such knowledge between individuals very effectively, and across generations, which seems to yield a compounding effect. I think small, compounding network effects like this are behind apparent human "superiority".
