PITTSBURGH (NewsRadio 1020 KDKA) — “Rise of the Planet of the Apes,” the newest installment for the “Planet of the Apes” movie series, hits theaters this weekend. In this story, the apes are advanced by a drug that is supposed to fix brain damage- but instead it evolves their intelligence and they revolt against humankind.

So just how smart are apes, chimps, and gorillas in real life? KDKA-AM’s Larry Richert and John Shumway talk to Henry Kacprzyk at the Pittsburgh Zoo and PPG Aquarium about how similar the simians there are to humans.

“When we put the orangutans out [for display]… they studied the window frames… unscrewed the bolts holding the glass… and traded them out for various ho-hos, soft drinks, and what have you,” said Henry.
