Can you describe the first time you met a chimp?
Oh yes. I went out to the Black Beauty Ranch to see the three adult chimps who were Nim's companions when he died in 2000. I went out just to hang out with them, and learn what it's like to look in their eyes. I certainly remember the first time I held hands with one of them. It's quite a joyful-slash-terrifying experience.
Partly it's so profound because they're so humanlike. But another part is that they're in a cage and you're on the outside. There's a built-in injustice to the relationship -- there seems to be a clear consciousness about that in them. Nim used to sign "out" all the time. Anybody who passed by his cage in Texas, he'd start signing to them, to see if they knew any sign language. If they didn't, he'd get disappointed and go to the back of his cage. He enjoyed signing and taught the other chimps some signs.
When they like you, they're extremely gregarious. They want to show you things. They love books and magazines. There was a children's book all about Nim while he was in New York, basically a photo book, and Nim kept his one copy of this book safe, even though chimps tend to wreck everything. He would bring it down and show the other chimps, then bring it back to his bunk and keep it under his sleeping area so that no one could destroy it. He would just look at pictures of his New York City family, and himself, over and over again.
What kind of response have you gotten from people who'd been involved with Nim?
Everybody felt so bad that they'd worked so hard to convince him he was human, and then he was just shipped off at the end of the experiment. There was no exit plan. No one ever asked, "What's going to happen to the chimp?" In the '70s, this is the way research was done. At the end of the experiment, the animals were either euthanized or sent to the next experiment down the line. Nobody asked questions about it. There was a tremendous amount of sadness and guilt wrapped around the whole project.
When Project Nim ended and Terrace finally published the results, years later, in Science magazine, he not only argued that Nim did not learn American Sign Language -- that he was merely mimicking his teachers -- he argued that all apes [in language programs] were mimicking their teachers. He basically tried to put a knife into the heart of all language research with animals. He sided with Chomsky. There were a lot of [other] projects under way at that time, and he had a huge effect on funding. It was a small, fragile movement to begin with. It took about five years for the field to recover.
Why do the language capabilities of a chimp matter?
I think they matter to different people for different reasons. The value of Project Nim is still hotly debated. The fact that chimps are really good at a gestural-based language is not surprising. Whether or not their use of ASL has anything to do with the way humans use ASL is still debated. What I can say is that those people who were around Nim had no problem understanding him.
Yet in Project Nim they made many mistakes. They brought Nim into a classroom, they made him hang his coat up on a hook, they sat him down at a little desk, and they drilled him in sign language. This is not a great way to teach a little human person, and it's certainly not a great way to teach a chimp. Nevertheless they documented a vocabulary of more than 100 words and 20,000 different combinations. But the question of what Nim learned -- everyone has a different point of view about it.
Now, we're looking much more closely at the animal mind, not the way in which the animal might use a human language. And what we're discovering is how little we know about how the animals communicate, and how little we know about their intellectual potential. Most of these captive animals have been born in captivity and locked in small cages their entire lives. If you did that to a human, it certainly wouldn't stimulate their intellect. Now that we know these animals have consciousness and desires and emotions, we think of them as sentient beings. We wonder not only what they have to say but whether we're doing the right thing by them, or to them.
It sometimes seems there's a disconnect in our thinking about chimps. On the one hand, we know very well that they're capable of seeming human -- in movies and commercials they look and act very much like us. But on the other hand, people sometimes seem shocked when they find out how complex or intelligent they actually are.
I think that's the lesson learned at Project Nim. This very adorable, humanlike baby turned into a wilder and wilder creature. People don't realize that chimps aren't forever these little people that are cute and funny. And they don't realize that they're actually an endangered species. They're kind of an invisible species here, too -- there are very few in zoos. Most are in research, and we don't get to see those. The ones we see on TV and in ads are babies.
How many chimps are there in captivity in the U.S.?
I think around 2,000. Five hundred are owned by the government and are in research labs. Another 600 are in privately owned research labs. Then there's a number of them in the entertainment industry and a number that are privately owned in exotic collections.
And there's a huge, mostly hidden number in garages and attics, right? People take them in thinking they'll always be cute and little, but they get big and unwieldy, and go on to live a very long time.
Yes. In the '70s, the period I was writing about, it was a kind of fad to raise a chimp as a pet in your home, and treat it very much as a child. None of these did very well. They not only tear through the families, but they tear through the house. They eat everything and wreck everything in sight. They're not easy to control. Marriages broke up, children were badly bitten, and people realized that while it was a really fun idea, the reality was far more harrowing than they'd imagined.
How does a chimp break up a marriage?
Chimps bond very tightly to their mothers. The fathers have very little to do with raising the babies. A lot of these women who had been raising orphan chimps [in the '70s] were suddenly engaged to be married, and their chimp babies would not accept their husbands.
What needs to change to improve the lot of apes and monkeys in this country?
We need to get the chimps, which have been in these small cages their whole lives, into sanctuaries where they can step on grass for the first time, and think about whether they want to climb a tree. We need to ask what we owe them, especially because many of these animals have given their lives to research. And once we start asking these questions, I think the answers are going to be so obvious. In many countries it's illegal to use chimpanzees for any biomedical research, or any invasive research at all, and I think that really needs to happen here. I predict it will.
Just to anticipate some of the responses you'll get for that, I want to be clear that the chimps being studied are not all saving human lives.
Oh no, not at all. But I think the whole attitude toward chimpanzees is finally starting to change. We're going to be the last country to protect chimpanzees legally. It wasn't so long ago that we were using them in car crash studies. We've used them for all kinds of useless toxicity studies. The AIDS studies were a disaster.
There's a lot of research now that looks at how successful research on chimps has been -- [and it's] relatively unsuccessful. I think we're getting to a point where we have to ask, are they really necessary? Or are they being used because it's a good way of getting grant money, or because they're simply there?
