She not unexpected—non-humans tended to dismiss the data as convenient widely scattered planets. Obviously there was no contact throughout the ages before space travel— and yet each planetary race can interbreed with a minimum of ten others distasteful to consider mating with someone who does not belong to my species." that's true of all other creatures, intelligent or not, with the sole Emmer would do—and she knew.

Outside of that, development. higher, she was as cruel to herself as she was to him. And yet he nothing mattered, and for the sake of alloying the lower with the "I do think I love you," she said. "And if love's enough, I may marry you in spite of everything. But you'll have to watch out whose children I have." She wriggled into his arms. 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. wanted her. 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 through —everybody they could coerce, seduce or marry—onward and upward.

He kissed her with sudden passion that even he knew was primitive. result of parallel evolution—not when a hundred human races are involved, and only the human race." others—and humans were more than a little feared. If they ever got together—but they hadn't except in agreement as to their common origin. very useful. A clear statement of their position was essential in helping him make up his mind. "You've heard of the adjacency mating principle?" asked Sam Halden. "Vaguely. Most people have if they've been around men." "We've got new data and are able to interpret it better. The theory is that humans who can mate with each other were once physically close. We've got a list of all our races arranged in sequence. If planetary equal intervals along a regular curve, a horseshoe loop that didn't close, though if the ends were extended, the lines would have crossed. "To the best of our knowledge," said Kelburn. "And whereas there are humans who are relatively near and not fertile, they can always mate with those they were adjacent to two hundred thousand years ago !" "The adjacency mating principle. I've never seen it demonstrated," murmured Taphetta, flexing his ribbons. "Is that the only era that satisfies the calculations?" differences, biological and in the scale of intelligence, it wasn't as great as once was thought. Anyway, non-humans weren't trained in the fine distinctions that men made among themselves. And, higher or plans, but I can't evade professional obligations, and an emergency such as this should cancel out any previous agreements. Still, what are you all day—it's micro-printing. However, you needn't be afraid that I'm defrauding you. It's honored everywhere we go and we go nearly everywhere in this sector—places men have never been." There was no choice if they wanted him, and they did. Besides, the they'll forward it the physical, to make use of her body so as to gain an advantage—what been inexplicably slow in developing and he wasn't completely aware of his place in the human hierarchy. mating scale, he shouldn't have been so interested. But his planet had breed with my kind, but there's a fair chance that I'd be fertile with thoughtfully. "Is there something wrong with the plants?" "What is it, some kind of toxic condition?" "The plants are healthy enough, but something's chewing them down as It was probably nothing to become alarmed at, but an animal on the ship just to get it in and now there were inaccessible corners and crevices everywhere that couldn't be closed off without rebuilding. 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 Perhaps it was intended to discourage Firmon, but he wished she hadn't tells me you're contemplating an experiment. I don't like it." "Pests on the ship? It's filthy! My people would never tolerate it!" "Neither do we." typical pest." "I'd say that, yes. It must be a fairly intelligent creature to be not a scrap of writing or a tool or a single picture. They covered "But they didn't leave any information for their descendants. Why?" for non-humans, that the race stuck together. They weren't actually 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 required for this expedition. I can't believe that the educational fractionally and ceaselessly.

That was what Taphetta had been afraid of—there was one kind of technical advancement that multiplied unceasingly. The race that could "Why do we have to watch it on the screen?" asked Meredith, glancing a minimum, but when you do use it, be vague. Don't try to imitate them retreated, skittering nervously. Without warning, the big one leaped and the small one tried to flee. In a few jumps, the big one caught up and mauled the other unmercifully. It continued to bite even after the little one lay still. At last it backed off and waited, watching for signs of motion. There was none. "It might. We had an audience." "What if they're smarter? Suppose they know a knife can't be used by a "That's part of our precautions. They'll never know until they try—and they'll never get away from the trap to try." 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. "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. It had been there as long as he'd known her, but it was closer to the surface now. "Do I have the right to condemn the unborn? Should I make them start lower than I am?" The conflict was not new nor confined to them. In one form or another, it governed personal relations between races that were united against non-humans, but held sharp distinctions themselves. "I haven't asked you to marry me," he said bluntly. "Because you're afraid I'd refuse." It was true no one asked a member of a higher race to enter a permanent union. "Why did you ever have anything to do with me?" demanded Halden. "Love," she said gloomily. "Physical attraction. But I can't let it lead me astray." about it, he'd give you children of the higher type." "He wouldn't, but he'd give you children if you were humble enough. There's a fifty per cent chance you might conceive."
