Gorilla Gamers
By asking chimpanzees and gorillas to solve puzzles on special touch-screens, zoo scientists can better understand how apes perceive the world around them.

Making New Milestones

For some Lincoln Park Zoo apes, including gorilla Azizi, sequencing objects is old news. Fisher Center Steve Ross explains how the next step will test their memory--and reveal more about how chimpanzees and gorillas think.

Give It a Try

Want to match your sequencing skills against another great ape? Learn the task in the interactive below, then try matching Azizi's memory. Afterward, go up against a true master: 7-year-old chimpanzee Ayumu at Kyoto University!

Learning More About Great Apes

Touch-screens aren't the tools zoo scientists use to study how apes learn and think. Token exchanges, termite fishing and space-use studies are among the groundbreaking research taking place at Lincoln Park Zoo's Lester E. Fisher Center for the Study and Conservation of Apes.
