Sally nodded reluctantly. "All right-they had atomic wars. So did we. If the CoDominium hadn't developed the Alderson Drive we'd have exterminated ourselves on Earth." She didn't like the answer, though. It was hard to accept. "Couldn't there have been another dominant species that killed itself off, and the Moties developed later?"
"No," Horvath said carefully. "Your own work, Lady Sally: you've shown just how well adapted the Motie form is to using tools. The mutation must have been a tool user to begin with-or was controlled by tool users. Or both."
"That's one war," Senator Fowler said. "The one that created the Moties as we see ‘em. You said two."
Horvath nodded sadly. "Yes, sir. The presently evolved Modes must have fought with atomic weapons. Later there was another period of radiation that split the species into all those castes-both the civilized forms and the animals. Plus intermediates like Watchmakers." Horvath looked apologetically at Blaine, but there was no sign of emotion.
Sigmund Horowitz cleared his throat. He was clearly enjoying this. "I believe the Browns were the original form. When the Whites became dominant they bred the other subspecies to their own uses. Controlled evolution again, you see. But some forms evolved by themselves."
"Then the asymmetric animals are not ancestors to Moties?" Senator Fowler asked curiously.
"No." Horowitz rubbed his hands together and fingered his pocket computer in anticipation. "They are degenerate forms-I can show you the gene mechanisms."
"That won't be necessary," Senator Fowler said hastily, "So we have two wars. Presumably the Mediators could have been bred in the second one-"
"Better make it three wars," Renner put in. "Even if we assume they ran out of radioactives in the second one."
"Why?" Sally demanded.
"You saw the planet. Then there's the adaptation to space," Renner said. He looked expectantly at Horvath and Horowitz.
Horowitz' triumphant grin was even broader now. "Your work again, my lady. The Moties are so well adapted to space that you wondered if they'd evolved there. They did." The xenobiologist nodded emphatically. "But not until they'd had a long evolutionary period on the planet itself Want me to review the evidence? Physiological mechanisms that adjust to low pressure and no gravity, intuitive astrogation-"
"I believe you," Sally said quietly.
"Mars!" Rod Blaine shouted. Everyone looked at him. "Mars. Is that what you're thinking, Kevin?"
Renner nodded. He seemed to be a man in conflict, his mind racing ahead and not liking what it found. "Sure," he said. "They fought at least one war with asteroids. Just look at the surface of Mote Prime, all torn by overlapping circular craters. It must have damn near wiped out the planet. It scared the survivors so much they moved all the asteroids out to where they couldn't be used that way again-"
"But the war killed off most of the higher life on the planet," Horowitz finished. "After a long time the planet was repopulated by Modes who'd adapted to space."
"But a very long time ago," Dr. Horvath protested. "The asteroid craters are cold and the orbits are stable. All this happened long ago."
Horvath didn't seem very comfortable with his conclusions, and Rod scratched a note. Not good enough, Rod thought. But-there must be some explanation...
"But they could still fight with asteroids," Horvath continued. "If they wanted to. It would take more energy, but as long as they're in the system they can be moved. We've no evidence of recent wars, and what has all this to do with us anyway? They used to fight,- they evolved the Mediators to stop it, and it worked. Now they don't fight any more."
"Maybe," Senator Fowler grunted. "And maybe not."
"They didn't fight us," Horvath insisted.
"Battle cruiser got destroyed," Fowler said. "OK, spare me the explanations. There's the midshipmen, and yeah, I've heard all the stories about them. The fact is, Dr. Horvath, if Moties fight each other you know damn well one faction's going to pick up allies among the outies and rebels. Hell, they might even encourage revolts, and by God's teeth we don't need that! There's another thing bothers me, too-have they got a planetary government?" There was more silence.
"Well, Sally?" the Senator demanded. "It's your field."
"They- Well, they have a kind of planetary government, Jurisdiction. A Master or a group of them takes jurisdiction over something and the rest go along."
Ben Fowler scowled at his niece. "Hell, we don't even let humans wander around the universe until they've got planetary governments. Can't you just see some Motie colony deciding to help a faction back home on Mote Prime?" He looked around the table and scowled again. "Damn it, don't all of you look at me like that. You'd think I wanted to shoot Father Christmas! I want trade with the Modes, but let's not forget the Prime Directive of the Empire."
"We need more time," Horvath protested. "You can't decide anything right now."
