Apes recognize photos of friends they haven't seen in years

Researchers have been studying apes, in particular, Bonobos, our closest relative in the animal world. They found that they recognized pictures of apes they had known, even after a period of separation lasting years.

The ability to recognize an individual from a photograph is remarkable. Remembering the other ape after a number of years is also remarkable.
They show a level of intelligence  beyond what we have given them credit for. The more we study apes or even other species, the more we discover how intelligent they really are. I wonder what they will study next about the Bonobos.
