Meet the people trying to help. That gap points to emotional differences between us and our simian peers that researchers who spend years raising apes almost as their children are eager to disprove or overcome.

But, boy, did we want to believe. The world was rapt. When Koko met the late actor Robin Williams, she smiled and they tickled each other. Years later, when he died by suicide, she spent the afternoon sitting somber in her enclosure.

Maybe most important, those who met Koko, from reporters to actors to the late Mr. Rogers, almost all say they felt something. How much apes really do resemble us in their emotional range and mental capacity will probably remain a mystery for longer than many of us will live.

It's not a set of crude gestures that your captive ape can master. The information is misleading. Please double-check your facts. University of Birmingham's Dr Adam Schembri said the headlines need " to be worded with care to avoid crating a misleading impression. We mastered ASL, not Koko. Marcus Perlman, a linguist, who studied Koko as part of his research into ape communication, weighed in. I would say that Koko used an inventory of learned, conventional gestures to communicate effectively with her caregivers about her daily life.

Many of her gestures were derived from ASL signs. But yes - Koko certainly did not master anything like a sign language. Gerardo Ortega, a sign language researcher, said Koko never mastered sign language.

He tweeted: "At most she ritualised the use of some signs about the here and now and used them only after trainer promoted her. However, some sign language users see things differently, especially some people who said she inspired them to learn sign language.

I watched a documentary about her and she drove me to learn sign language to communicate to my friends who are deaf. As someone whose parents were deaf and is fluent in ASL, I find the reverence for Koko and her speaking sign language fascinating. Speaking sign language has always felt perceived as more prestigious than other languages, at least in my experience.

And the apes did learn to use some hand gestures in this way. Prof Turner said: "These languages use the face, body and hands in an integrated way, exploiting their multidimensional, spatial medium through the layering of simultaneous and extremely precise visual elements.
