In repose, Taphetta the Ribboneer resembled a fancy giant bow on a Taphetta rattled the head fronds together in a surprisingly good ages before space travel— and yet each planetary race can interbreed with a minimum of ten others ! That's more than a legend—one hell of a lot more!" "It is impressive," admitted Taphetta. "But I find it mildly "That's because you're unique," said Halden. "Outside of your own world, there's nothing like your species, except superficially, and that's true of all other creatures, intelligent or not, with the sole exception of mankind. Actually, the four of us here, though it's accidental, very nearly represent the biological spectrum of human development. "Emmer, a Neanderthal type and our archeologist, is around the Taphetta rustled his speech ribbons quizzically. "But I thought it was children—and they might be his. He twisted away. With those thoughts, he was as bad as she was. Were they all that way, every one of them, crawling upward out of the slime toward the highest goal they could conceive of? Climbing over—no, through —everybody they could coerce, seduce or marry—onward and commented Taphetta dryly. "It seems an unnecessary simplification." result of parallel evolution—not when a hundred human races are involved, and only the human race." "I can't think of a better explanation." Taphetta rearranged his 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 high as anything in the known section of the Milky Way, and there were together—but they hadn't except in agreement as to their common origin. Still, Taphetta the Ribboneer was an experienced pilot and could be Taphetta rustled. "The math is accurate?" Taphetta waved a ribbon at the chart. "And you think that where the two 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 the fine distinctions that men made among themselves. And, higher or lower, he was as good a biologist as the other was a mathematician. And Taphetta crinkled politely at the reference to his skill. "I had other "I'm complimented that you like our contract so well," said Taphetta, It would do no good to explain that Taphetta wasn't a worm, that his 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 prepared for the multitude of life-forms they'd meet in space. Firmon's "Can't. This is as good as I can get it. Taphetta thought you could do Use them." "It's an animal," said Firmon. "We tried poison and got a few, but now Taphetta sat in a chair designed for humans. With a less flexible body, "Neither do we." The Ribboneer's distaste subsided. "What kind of creatures are they?" Taphetta rustled. "Have you found out how it got on?" 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 "That's what I don't like," said Taphetta, curling. "Let me think it 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 their camp." "I don't question your authority," crinkled Taphetta. "To me, all humans—late or early and male or female—look remarkably alike. If you "Very large," agreed Taphetta. It was difficult to tell whether he was "A faster-than-light drive and an extremely long life," mused Taphetta. "But they didn't leave any information for their descendants. Why?" "Who knows? Their mental processes were certainly far different from ours. They may have thought we'd be better off without it. We do know they were looking for a special kind of planet, like Earth, because they visited so many of that type, yet different from it because they never stayed. They were pretty special people themselves, big and long-lived, and maybe they couldn't survive on any planet they found. Perhaps they had ways of determining there wasn't the kind of planet they needed in the entire Milky Way. Their science was tremendously advanced and when they learned that, they may have altered their germ plasm and left us, hoping that some of us would survive. Most of us did." independently and those who did were scattered equally among early and late species. It's well known that individuals among my people are often as bright as any of Halden's or Meredith's, but as a whole we don't have the total capacity that later Man does, and yet we're as advanced in civilization. The difference? It must lie somewhere in the Taphetta. atomic—because they were human. That was sometimes a frightening thing for non-humans, that the race stuck together. They weren't actually aggressive, but their total number was great and they held themselves Taphetta changed his questioning. "What do you expect to gain from this was required for this expedition. I can't believe that the educational institutions that are backing you did so purely out of intellectual curiosity." "No doubt," said Taphetta. "An archeologist would be interested in achieved that only within the last thousand years." "But I think we have a better one than they did," said the Ribboneer. "There may be things we can learn from them in mechanics or physics, but wouldn't you say they were better biologists than anything else?" "I thought so," said Taphetta. "I never paid much attention to your fractionally and ceaselessly. "I don't like to, but we'll have to risk using bait for your pest." "To the individual, they are, but it won't matter if you discover as much as you think you will. The difference is this: My terms don't Taphetta was wrong That was what Taphetta had been afraid of—there was one kind of exactly like the pests? And if not, will the pests be fooled?" "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 creature without real hands?" "That's part of our precautions. They'll never know until they try—and they'll never get away from the trap to try." like the way your primitive mind works. At times I actually think of marrying you." her own world. She had something else in mind. "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 not make a play for Kelburn? If you're going to be scientific about it, he'd give you children of the higher type." like him and he wouldn't marry me." "He wouldn't, but he'd give you children if you were humble enough. There's a fifty per cent chance you might conceive."
