"Yes, I'm sure you do." Mclntyre gave her a skeptical glance. "This is important, Miss Fellowes. Has anyone been taping these clicks and growls of his?"

"I hope so. I don't know." (She realized that she had been going to ask Dr. Hoskins about that. But she had forgotten all about it.)

Timmie said something again, this time with a different intonation, more melodic, almost plaintive.

"You see, Dr. Mclntyre? That was nothing like what he said before. -I think he wants to play with your hair again."

"You're only guessing about that, aren't you?"

"Of course I am. I don't speak Neanderthal very fluently yet. But look-look, he's reaching out for you the way he did just before."

Mclntyre didn't seem to care for having his hair yanked again. He smiled and extended a finger to Timmie instead, but the boy had no interest in that. He said so, with an extended series of clicks punctuated by three unfamiliar high-pitched sounds that were midway between a growl and a whine.

"I think you're right, Miss Fellowes!" said Mclntyre, his own voice rising. He looked flustered. "It does sound like formal speech! Definite formal speech. -How old do you think this child is?"

"Somewhere between three and four. Closer to four, is my guess. There's no reason to be so surprised that he can speak so well. Four-year-olds are quite articulate, Dr. Mclntyre. If you have any children yourself-"

"I do, as a matter of fact. She's almost diree and she has quite a lot to say. But this is a Neanderthal child."

"Why should that matter? Wouldn't you expect a Neanderthal child of his age to know how to speak?"

"At this point we have no real reason, Miss Fellowes, to assume that any Neanderthals of any age were capable of speech as we understand the concept. That's why the sounds this child is making are of such immense importance to our knowledge of prehistoric man. If they represent speech, actual organized patterns of sound with distinct grammatical structure-"

"But of course that's what they represent!" Miss Fellowes burst out. "Speech is the one thing that distinguishes human beings from animals, isn't it? And if you think that you can get me to believe for one moment that this little boy isn't a human being, you-"

"Certainly the Neanderthals were human, Miss Fellowes. I'd be the last person to dispute that. But that doesn't mean they had a spoken language."

"What? How could they have been human and not be able to speak?"

Mclntyre drew a deep breath, the kind of exaggerated gesture of carefully hoarded patience that Miss Fellowes recognized all too well. She had spent her whole working life around people who assumed that she knew less than they did, because she was "only" a nurse. Most of the time that wasn't so, at least in the hospital. But this wasn't the hospital; and when it came to Neanderthals, she knew virtually nothing at all, and this fair-haired young man was an expert. She compelled herself to maintain an expression of studious interest.

"Miss Fellowes," Mclntyre began, in an unmistakable here-comes-the-lecture tone, "in order for a creature to be able to speak, it needs not only a certain degree of intelligence but also the physical capacity to produce complex sounds. Dogs are quite intelligent, and have considerable vocabularies-but there's a difference between knowing what 'sit' and 'fetch' mean and being able to say 'sit' and 'fetch' yourself, and no dog since time began has ever been able to manage anything better than 'woof And surely you know that chimpanzees and gorillas can be taught to communicate quite well, through signs and gestures-but they can't shape words any more than dogs can. They simply don't have the anatomical equipment for it."

"I wasn't aware of that."

"Human speech is a very complicated thing," said Mclntyre. He tapped his throat. "The key to it is a tiny U-shaped bone called the hyoid, at the base of the tongue. It controls eleven small muscles that move the tongue and the lower jaw and also are capable of lifting and depressing the larynx to bring forth the vowels and consonants that make up speech. The hyoid bone isn't present in apes. Therefore all they can do is grunt and hiss."

"What about parrots and myna birds? They can speak actual words. Are you telling me that the hyoid bone evolved in them, and not in chimpanzees?"

"Birds like parrots and mynas simply mimic the sounds humans make, using entirely different anatomical structures. But what they do can't be regarded as speech. There isn't any verbal understanding there. They don't have any idea of what they're saying. It's just a playback of the sounds they hear."

"All right. And Neanderthals-don't they have hyoid bones? If they're considered human beings, they must."

"We haven't been sure that they do," Mclntyre said. "You need to bear in mind, first, that the total number of Neanderthal skeletons ever discovered, since the first one came to light in 1856, is not quite two hundred, and a lot of those are fragmentary or otherwise badly damaged. And, second, that the hyoid bone is very small and isn't connected to any other bones of the body, only to the muscles of the larynx. When a body decays, the hyoid falls away and can easily be separated from the rest of the skeleton. Of all the Neanderthal fossils we've examined, Miss Fellowes, a total of one-one-still had a hyoid bone in place."

"But if one of them had it, all of them must have!"

Mclntyre nodded. "Very likely so. But we've never seen a Neanderthal larynx. Soft tissues don't survive, of course. And so we don't know what function the hyoid served in the Neanderthal. Hyoid or not, we've had no way of being certain that the Neanderthals actually were capable of speech. All we can say is that the anatomy of the vocal apparatus was probably the same in Neanderthals as it is in modern humans. Probably. But whether it was developed sufficiently to allow them to articulate understandable words-or whether their brains were advanced enough to handle the concept of speech-"

Timmie was clicking and growling again.

"Listen to him," Miss Fellowes said triumphantly. "There's your answer! He's got a fine language and he speaks it perfectly well. And before he's been here much longer, he'll be speaking English, too, Dr. Mclntyre. I'm certain of that. And then you won't need to speculate any longer about whether the Neanderthals were capable of speech."

Mclntyre seemed to want to solve all the Neanderthal riddles at once. He made clicking sounds at Timmie in the hope of eliciting clicks in return; he produced colored plastic blocks from his briefcase, some sort of intelligence test, no doubt, and tried to get Timmie to arrange them in sequences of size and color; he offered the boy crayons and paper and stood back waiting for him to draw something, which Timmie seemed to have no interest in doing; he had Miss Fellowes lead Timmie around the room by the hand, and photographed him as he moved. There were other tests he wanted to carry out on Timmie, too; but Timmie had his own thoughts about that. Just as Mclntyre began to set up some arrangement of spools and spindles, which looked like a toy but was actually a device to measure the boy's coordination, Timmie sat down in the middle of the floor and began to cry. Loudly.

It was the first time he had really cried-as opposed to sobbing or whimpering or moaning-since the night he had arrived. It was the very familiar cranky bawling of a very tired child who had been pushed too far. Miss Fef-lowes was glad to hear it, though she was astonished at how wide his mouth could get when he opened it to its full extent, how his nose suddenly seemed even bigger than it already was, how far those strange heavy ridges of bone over his eyes protruded when he scrunched his eyes closed the way he was doing now. With his face distorted like this in anguish, he looked almost terrifyingly alien.

And yet, and yet-that wailing sound, that ululating outpouring of emotion-if she didn't look at him, she could easily believe that the child who was thumping his heels against the floor and screaming his heart out was simply any ordinary four-year-old having a severe attack of impatience.

"What did I do that upset him like that?" Mclntyre asked.

"You outlasted his attention span, I imagine," said Miss Fellowes. "You wore out your welcome. He's only a little boy, Dr. Mclntyre. He can't be expected to put up with an endless amount of chivvying and probing. -A little boy who's very recently been through a highly traumatic separation from anything and everything that he can understand, I ought to remind you."

"But I wasn't chivvying and-well, perhaps I was. I'm sorry about that. -Here, Timmie-here, see the hair? See the bright hair? Do you want to play with my hair? Do you want to pull my hair?"

Mclntyre was dangling his golden forelock practically in Timmie's face. Timmie took no notice. His screaming grew even louder.

Disgustedly Miss Fellowes said, "He doesn't want to play with your hair right now, Dr. Mclntyre. And if he does decide to pull it, I think you'll regret it. Best to let him be. There'll be plenty of other opportunities to examine him."

"Yes. So there will." The paleoanthropologist stood up, looking abashed. "You understand, Miss Fellowes, this is like being handed a sealed book containing the answers to all the mysteries of the ages. I want to open it and read it right away. Every page of it."

"I understand. But I'm afraid that your book is hungry and cranky and I think he'd like to go to the bathroom, besides."

"Yes. Yes, of course."

Mclntyre hastily began to gather up all of his testing equipment. As he started to put the spools and spindles away, Miss Fellowes said, "Can you leave one of those here?"

"You want to test his intelligence yourself?"

"I have no need to test his intelligence, doctor. He seems quite intelligent to me. But I think he could use a few toys, and this one already happens to be here."

Color came to Mclntyre's cheeks once again. He seemed to blush very readily, Miss Fellowes thought.

"Of course. Here."

"And-speaking of open books, Dr. Mclntyre, do you think you could arrange to get me some material about Neanderthal Man? Two or three basic texts, something that might provide me with a little of the fundamental information that nobody has bothered to supply me with up till now? -They can be fairly technical. I'm quite capable of reading scientific prose. I need to know things about the Neanderthal anatomy, their way of life, the sort of foods they ate, whatever has been discovered up to this point. Could you do that for me?"
