This article seems very narrow and at least a bit wrong. I talk with a Gorilla on occasion (yeah, literally,) and she talks back. Her name is Koko. She understands much spoken English and uses a variant of ASL to speak back. She talks about her life and what's going on with her on that particular day. She wants to know about my life and what's going on with me. She talks about other people and her mate Ndume. She's self conscious at times and gregarious and fun at times. She enjoys watching television and even has favorite movies. And Koko isn't the only one. There are other apes that speak with humans regularly and richly. But beyond that, we also know from decades of research on gorillas in their native habitat that they have a very rich gestural language that they depend on for survival. It's that native gestural language, it's thought, which makes it so easy for apes to pick up sign language as a means to talk with humans.
