Could a sighting by researchers in Uganda’s Kibale National Park be a clue that chimps share just for the sake of sharing?
Whether it’s a college student playing a roommate their favorite song or a child showing their parent a dirty rock they found on the ground , humans love sharing things we find fascinating just for the sake of it. The desire to sit your loved ones down and force them to watch your favorite movie has long been thought to be distinctly human— an inclination not shared by our primate relatives.
The ability to “share” attention is thought to be a pivotal development in human evolution, serving as a needed precursor to more complex cooperative behaviors. Babies as young as 10 months hold out items for their caretakers to see, with seemingly no other purpose beyond letting mom, dad or big sister in on something they find cool or interesting.
This all happened just once and has not yet been seen again—either with Fiona or the other chimps that Slocombe follows. But that one instance was enough to add an exciting twist to Slocombe’s research. Confirming that Fiona’s goal was just for her mom to pay attention to something and nothing more is tricky to ascertain, especially with only one observation. The team was particularly interested in whether Fiona’s action could be part of a mysterious behavior known as “leaf grooming.
