Certain apes appear to be much smarter than others, with at least one chimpanzee now characterized as being "exceptional" when compared to other chimps.

The standout chimp, an adult female in her 20's named Natasha, scored off the charts in a battery of tests. The findings, published in the latest Philosophical Transactions of the Royal Society B, suggest that geniuses exist among non-humans, but that no one attribute constitutes intelligence.

Instead, a perfect storm of abilities seems to come together to create the Einsteins of the animal kingdom. Natasha's keepers at the Ngamba Island chimpanzee sanctuary in Uganda knew she was special even before the latest study.
