"They already had it, for sure," Maddson completed for him. "We sure as hell found them on Ganymede."
"Quite. And that ship was no beginner’s first attempt, either. You know, I’m beginning to think that whoever the Lambians were, they weren’t Ganymeans."
"I think you’re right," Maddson confirmed. "The Ganymeans were a totally different biological species. Wouldn’t you expect that if they were the opposition in Lambia, somehow it would show up in the Lunarian writings? But it doesn’t. Everything we’ve examined suggests that the Cerians and the Lambians were simply different nations of the same race. For example, we’ve found extracts from what appear to be Cerian newspapers, which included political cartoons showing Lambian figures; the figures are drawn as human forms. That wouldn’t be so if the Lambians looked anything like the Ganymeans must have looked."
"So it appears the Ganymeans had nothing to do with the war," Hunt concluded.
"Right."
"So where do they fit in?"
Maddson showed his empty palms. "That’s the funny thing. They don’t seem to fit anywhere-at least, we haven’t even found anything that looks like a reference to them."
"Maybe they’re just a big red herring, then. I mean, we’ve only supposed that they came from Minerva; nothing actually demonstrates that they did. Perhaps they never had anything to do with the place at all."
"Could well be. But I can’t help feeling that…"
The chime on Maddson’s desk display console interrupted the discussion. He excused himself and touched a button to accept the call.
"Hi, Don," said the face of Hunt’s assistant, upstairs in Group L’s offices. "Is Vic there?" He sounded excited. Maddson swiveled the unit around to point in Hunt’s direction.
"It’s for you," he said needlessly.
"Vic," said the face without preamble. "I’ve just had a look at the reports of the latest tests that came in from Jupiter Four two hours ago. That ship under the ice and the big guys inside it-they’ve completed the dating tests." He drew a deep breath. "It looks like maybe we can forget the Ganymeans in all this Charlie business. Vic, if all the figures are right, that ship has been sitting there for something like twenty-five million years!"
Chapter Fifteen
Caldwell moved a step closer to inspect more carefully the nine-foot-high plastic model standing in the middle of one of the laboratories of the Westwood Biological Institute. Danchekker gave him plenty of time to take in the details before continuing.
"A full-size replica of a Ganymean skeleton," he said. "Built on the strength of the data beamed back from Jupiter. The first indisputable form of intelligent alien life ever to be studied by man." Caldwell looked up at the towering frame, pursed his lips in a silent whistle, and walked in a slow circle around and back to where the professor was standing. Hunt simply stood and swept his eyes up and down the full length of the model in wordless fascination.
"That structure is in no way related to that of any animal ever studied on Earth, living or extinct," Danchekker informed them. He gestured toward it. "It is based on a bony internal skeleton, walks upright as a biped, and has a head on top-as you can see; but apart from such superficial similarities, it has clearly evolved from completely unfamiliar origins. Take the head as an obvious example. The arrangement of the skull cannot be reconciled in any way with that of known vertebrates. The face has not receded back into the lower skull, but remains a long, down-pointing snout that widens at the top to provide a broad spacing for the eyes and ears. Also, the back of the skull has enlarged to accommodate a developing brain, as in the case of man, but instead of assuming a rounded contour, it bulges back above the neck to counterbalance the protruding face and jaw. And look at the opening through the skull in the center of the forehead; I believe that this could have housed a sense organ that we do not possess-possibly an infrared detector inherited from a nocturnal, carnivorous ancestor."
Hunt moved forward to stand next to Caldwell and peered intently at the shoulders. "These are unlike anything I’ve ever come across, too," he commented. "They’re made up of… kind of overlapping plates of bone. Nothing like ours at all."
"Quite," Danchekker confirmed. "Probably adapted from the remains of ancestral armor. And the rest of the trunk is also quite alien. There is a dorsal spine with an arrangement of ribs below the shoulder plates, as you can see, but the lowermost rib-immediately above the body cavity-has developed into a massive hoop of bone with a diametral strut stretching forward from an enlarged spinal vertebra. Now, notice the two systems of smaller linked bones at the sides of the hoop…" He pointed them out. "They were probably used to assist with breathing by helping to expand the diaphragm. To me, they look suspiciously like the degenerate remnants of a paired-limb structure. In other words, although this creature, like us, had two arms and walked on two legs, somewhere in his earlier ancestry were animals with three pairs of appendages, not two. That in itself is enough to immediately rule out any kinship with every vertebrate of this planet."
Caldwell stooped to examine the pelvis, which comprised just an arrangement of thick bars and struts to contain the thigh sockets. There was no suggestion of the splayed dish form of the lower human torso.
"Must’ve had peculiar guts, too," he offered.
"It could be that the internal organs were carried more by suspension from the hoop above than by support from underneath," Danchekker suggested. He stepped back and indicated the arms and legs. "And last, observe the limbs. Both lower limbs have two bones as do ours, but the upper arm and thigh are different-they have a double-bone arrangement as well. This would have resulted in vastly improved flexibility and the ability to perform a whole range of movements that could never be duplicated by a human being. And the hand has six digits, two of them opposing; thus its owner effectively enjoyed the advantages of having two thumbs. He would have been able to tie his shoes easily with one hand."
Danchekker waited until Caldwell and Hunt had fully studied every detail of the skeleton to their satisfaction. When they looked toward him again, he resumed: "Ever since the age of the Ganymeans was verified, there has been a tendency for everybody to discount them as merely a coincidental discovery and having no direct bearing on the Lunarian question. I believe, gentlemen, that I am now in a position to demonstrate that they had a very real bearing indeed on the question."
Hunt and Caldwell looked at him expectantly. Danchekker walked over to a display console by the wall of the lab, tapped in a code, and watched as the screen came to life to reveal a picture of the skeleton of a fish. Satisfied, he turned to face them.
"What do you notice about that?" he asked.
Caldwell stared obediently at the screen for a few seconds while Hunt watched in silence.
"It’s a funny fish," Caldwell said at last. "Okay-you tell me."
"It is not obvious at first sight," Danchekker replied, "but by detailed comparison it is possible to relate the structure of that fish, bone for bone, to that of the Ganymean skeleton. They’re both from the same evolutionary line."
"That fish is one of those that were found on the Lunarian base on Farside," Hunt said suddenly.
"Precisely, Dr. Hunt. The fish dates from some fifty thousand years ago, and the Ganymean skeleton from twenty-five million or so. It is evident from anatomical considerations that they are related and come from lines that branched apart from a common ancestral life form somewhere in the very remote past. It follows that they share a place of origin. We already know that the fish evolved in the oceans of Minerva; therefore, the Ganymeans also came from Minerva. We thus have proof of something that has been merely speculation for some time. All that was wrong with the earlier assumption was our failure to appreciate the gap in time between the presence of the Ganymeans on Minerva, and that of the Lunarians."
