She provocatively arched her back. Not even the women of Kelburn's race had a body like hers and she knew it. race an inferiority complex—but then he tried to climb it! In repose, Taphetta the Ribboneer resembled a fancy giant bow on a was purely reflexive. His hand swung out and he could feel the flesh give when his knuckles struck it. his wide, thin body, which constituted the knot at the middle. His neck was flat, too, arching out in another loop. Of all his features, only his head had appreciable thickness and it was crowned with a dozen long feel that attraction to her? "Try Emmer," he suggested tiredly. "He'll find you irresistible, and he's even more savage than I am." "Is he?" She smiled enigmatically. "Maybe, in a biological sense. Too much, though. You're just right." "That's because you're unique," said Halden. "Outside of your own Emmer would do—and she knew. She had no concept of love outside of accidental, very nearly represent the biological spectrum of human development. "Emmer, a Neanderthal type and our archeologist, is around the higher, she was as cruel to herself as she was to him. And yet he wanted her. Emmer's side. Meredith, linguist, is on the other side of the middle. advantage?—for the children she intended to have. Outside of that, nothing mattered, and for the sake of alloying the lower with the The racial disparity was great and she had provoked him, but it was not completely her fault. Besides.... Besides what? She had a beautiful body that could bear superior children—and they might be his. Meredith and a similar though lesser chance that her fertility may He twisted away. With those thoughts, he was as bad as she was. Were you in spite of everything. But you'll have to watch out whose children through —everybody they could coerce, seduce or marry—onward and upward. He raised his hand, but it was against himself that his anger unbroken line of evolution that could be traced back a billion years." "You're thinking of Earth," said Halden. "Humans require a certain kind only the human race." ribbons. "Frankly, no one else is much interested in Man's theories about himself." It was easy to understand the attitude. Man was the most numerous though not always the most advanced—Ribboneers had a civilization as Halden flushed the sarcasm wasn't necessary. It was true that Kelburn was the most advanced human type present, but while there were differences, biological and in the scale of intelligence, it wasn't as great as once was thought. Anyway, non-humans weren't trained in ability." Taphetta crinkled politely at the reference to his skill. "I had other plans, but I can't evade professional obligations, and an emergency an equal lack of grace. He seemed to have difficulty in taking his eyes off Meredith, though, since he was a notch or so above her in the mating scale, he shouldn't have been so interested. But his planet had been inexplicably slow in developing and he wasn't completely aware of his place in the human hierarchy. the physical, to make use of her body so as to gain an advantage—what "More than a man?" Firmon leered at Meredith and, when she failed Halden took a deep breath. "Seems all right to me." evolution had taken a different course, but that he was in no sense less complex than Man. It was a paradox that some biologically higher humans hadn't developed as much as lower races and actually weren't Halden. "Do anything you can to give it to him." I have." She wriggled into his arms. Use them." "It's an animal," said Firmon. "We tried poison and got a few, but now they won't touch the stuff. I had electronics rig up some traps. The Halden glowered at the man. "How long has this been going on?" It was probably nothing to become alarmed at, but an animal on the ship was a nuisance, doubly so because of their pilot. "Tell me what you know about it," said Halden. They couldn't set up a continuous watch and shoot the animals down because there weren't that many men to spare. Besides, the use of Halden started. So she Halden shrugged. "We've got to have better air. It might work." "Pests on the ship? It's filthy! My people would never tolerate it!" "Neither do we." The Ribboneer's distaste subsided. "What kind of creatures are they?" smarter?" "I'd say that, yes. It must be a fairly intelligent creature to be so hard to get rid of. But it can be lured into traps, if the bait's humans. Is there anything else you can tell me about the hypothetical ancestor?" Emmer didn't look like the genius he was—a Neanderthal genius, but nonetheless a real one. In his field, he rated very high. He raised a stubble-flecked cheek from a large thick-fingered paw and ran shaggy aggressive, but their total number was great and they held themselves aloof. The unknown ancestor again. Who else had such an origin and, it was tacitly assumed, such a destiny? It was Halden who answered him. "There's the satisfaction of knowing curiosity." "Cultural discoveries," rumbled Emmer. "How did our ancestors live? When a creature is greatly reduced in size, as we are, more than fractionally and ceaselessly. "I don't like to, but we'll have to risk using bait for your pest." He'd have done it anyway, but it was better to have the pilot's consent. And there was one question Halden wanted to ask defeat. This time it had no trouble with the raised section. It leaped and landed on top and made considerable noise in doing so. The big animal The small one stood still till the last instant—and then a paw flickered out and an inch-long knife blade plunged into the throat of the charging creature. Red spurted out as the bigger beast screamed. The knife flashed in and out until the big animal collapsed and stopped moving. The small creature removed the knife and wiped it on the pelt of its foe. Then it scampered back to the platform on which the knife had been found— and laid it down "The electronic puppets were a good imitation, but the animals don't have to identify them as their species. If they're smart enough, they'll know the value of a knife, no matter who uses it." "What if they're smarter? Suppose they know a knife can't be used by a "Very good. I never thought of that," said Meredith, coming closer. "I like the way your primitive mind works. At times I actually think of marrying you." "Primitive," he said, alternately frozen and thawed, though he knew that, in relation to her, he was not advanced. "It's almost a curse, isn't it?" She laughed and took the curse away by leaning provocatively against him. "But barbaric lovers are often nice." Here we go again, he thought drearily, sliding his arm around her. To her, I'm merely a passionate savage. They went to his cabin. She sat down, smiling. Was she pretty? Maybe. For her own race, she primeval Earth." He said nothing she knew as well as he that Earth was as advanced as "I don't think I will, though. We might have children." "Would it be wrong?" he asked. "I'm as intelligent as you. We wouldn't have subhuman monsters." "It would be a step up—for you." Under her calm, there was tension. "Why did you ever have anything to do with me?" demanded Halden. "Love," she said gloomily. "Physical attraction. But I can't let it There's a fifty per cent chance you might conceive."
