flourished and died out long before modern man began his own ascent?
On the other hand, the fact that Charlie was found on the Moon presupposed a civilization sufficiently advanced technically to send him there. Surely, on the way toward developing space flight, they would have evolved a worldwide technological society, and in doing so would have made machines, erected structures, built cities, used metals, and left all the other hallmarks of progress. If such a civilization had once existed on Earth, surely centuries of exploration and excavation couldn’t have avoided stumbling on at least some traces of it. But not one instance of any such discovery had ever been recorded. Although the conclusion rested squarely on negative evidence, Hunt could not, even with his tendency toward open-mindedness, accept that an explanation along these lines was even remotely probable.
The only alternative, then, was that Charlie came from somewhere else. Clearly this could not be the Moon itself: It was too small to have retained an atmosphere anywhere near long enough for life to have started at all, let alone reach an advanced level-and of course, his spacesuit showed he was just as much an alien there as was man.
That only left some other planet. The problem here lay in Charlie’s undoubted human form, which Caldwell had stressed although he hadn’t elected to go into detail. Hunt knew that the process of natural evolution was accepted as occurring through selection, over a long period, from a purely random series of genetic mutations. All the established rules and principles dictated that the appearance of two identical end products from two completely isolated families of evolution, unfolding independently in different corners of the universe, just couldn’t happen. Hence, if Charlie came from somewhere else, a whole branch of accepted scientific theory would come crashing down in ruins. So-Charlie couldn’t possibly have come from Earth. Neither could he possibly have come from anywhere else. Therefore, Charlie couldn’t exist. But he did.
Hunt whistled silently to himself as the full implications of the thing began to dawn on him. There was enough here to keep the whole scientific world arguing for decades.
Inside the Westwood Biological Institute, Caldwell, Lyn Garland, Hunt, and Gray were met by a Professor Christian Danchekker. The Englishmen recognized him, since Caldwell had introduced them earlier by vi-phone. On their way to the laboratory section of the institute, Danchekker briefed them further.
In view of its age, the body was in an excellent state of preservation. This was due to the environment in which it had been found-a germ-free hard vacuum and an abnormally low temperature sustained, even at Lunar noon, by the insulating mass of the surrounding rock. These conditions had prevented any onset of bacterial decay of the soft tissues. No rupture had been found in the spacesuit. So the currently favored theory regarding cause of death was that a failure in the life-support system had resulted in a sudden fall in temperature. The body had undergone deep freezing in a short space of time with a consequent abrupt cessation of metabolic processes; ice crystals, formed from body fluids, had caused widespread laceration of cell membranes. In the course of time most of the lighter substances had sublimed, mainly from the outer layers, to leave behind a blackened, shriveled, natural kind of mummy. The most seriously affected parts were the eyes, which, composed for the most part of fluids, had collapsed completely, leaving just a few flaky remnants in their sockets.
A major problem was the extreme fragility of the remains, which made any attempt at detailed examination next to impossible. Already the body had undergone some irreparable damage in the course of being transported to Earth and in the removal of the spacesuit; only the body’s being frozen solid during these operations had prevented the situation from being even worse. That was when somebody had thought of Felix Borlan at IDCC and an instrument being developed in England that could display the insides of things. The result had been Caldwell’s visit to Portland.
Inside the first laboratory it was dark. Researchers were using binocular microscopes to study sets of photographic transparencies arranged on several glass-topped tables, illuminated from below. Danchekker selected some plates from a pile and, motioning the others to follow, made his way over to the far wall. He positioned the first three of the plates on an eye-level viewing screen, snapped on the screen light, and stepped back to join the expectant semicircle. The plates were X-ray images showing the front and side views of a skull. Five faces, thrown into sharp relief against the darkness of the room behind, regarded the screen in solemn silence. At last Danchekker moved a pace forward, at the same time half turning toward them.
'I need not, I feel, tell you who this is.' His manner was somewhat stiff and formal. 'A skull, fully human in every detail-as far as it is possible to ascertain by X rays, anyway.' Danchekker traced along the line of the jaw with a ruler he had picked up from one of the tables. 'Note the formation of the teeth-on either side we see two incisors, one canine, two premolars, and three molars. This pattern was established quite early in the evolutionary line that leads to our present day anthropoids, including, of course, man. It distinguishes our common line of descent from other offshoots, such as the New World monkeys with a count of two, one, three, three.'
'Hardly necessary here,' Hunt commented. 'There’s nothing apelike or monkeylike about that picture.'
'Quite so, Dr. Hunt,' Danchekker returned with a nod. 'The reduced canines, not interlocking with the upper set, and the particular pattern of the cusps-these are distinctly human characteristics. Note also the flatness of the lower face, the absence of any bony brow ridges… high forehead and sharply angled jaw, well-rounded braincase. These are all features of true man as we know him today, features that derive directly from his earlier ancestors. The significance of these details in this instance is that they demonstrate an example of true man, not something that merely bears a superficial resemblance to him.'
The professor took down the plates and momentarily flooded the room with a blaze of light. A muttered profanity from one of the scientists at the tables made him switch off the light hastily. He picked up three more plates, set them up on the screen, and switched on the light to reveal the side view of a torso, an arm, and a foot.
'Again, the trunk shows no departure from the familiar human pattern. Same rib structure… broad chest with well-developed clavicles… normal pelvic arrangement. The foot is perhaps the most specialized item in the human skeleton and is responsible for man’s uniquely powerful stride and somewhat peculiar gait. If you are familiar with human anatomy, you will find that this foot resembles ours in every respect.'
'I’ll take your word for it,' Hunt conceded, shaking his head. 'Nothing remarkable, then.'
'The most significant thing, Dr. Hunt, is that nothing is remarkable.'
Danchekker switched off the screen and returned the plates to the pile. Caldwell turned to Hunt as they began walking back toward the door.
'This kind of thing doesn’t happen every day,' he grunted. 'An understandable reason for wanting some… er… irregular action, you would agree?'
Hunt agreed.
A passage, followed by a short flight of stairs and another passage, brought them to a set of double doors bearing the large red sign STERILE AREA. In the anteroom behind, they put on surgical masks, caps, gowns, gloves, and overshoes before passing out through another door at the opposite end.
In the first section they came to, samples of skin and other tissues were being examined. By reintroducing the substances believed to have escaped over the centuries, specimens had been restored to what were hoped to be close approximations to their original conditions. In general, the findings merely confirmed that Charlie was as human chemically as he was structurally. Some unfamiliar enzymes had, however, been discovered. Dynamic computer simulation suggested that these were designed to assist in the breakdown of proteins unlike anything found in the diet of modern man. Danchekker was inclined to dismiss this peculiarity with the rather vague assertion that 'Times change,' a remark which Hunt appeared to find disturbing.
The next laboratory was devoted to an investigation of the spacesuit and the various other gadgets and implements found on and around the body. The helmet was the first exhibit to be presented for inspection. Its back and crown were made of metal, coated dull black and extending forward to the forehead to leave a transparent visor extending from ear to ear. Danchekker held it up for them to see and pushed his hand up through the opening at the neck. They could see clearly the fingers of his rubber glove through the facepiece.
'Observe,' he said, picking up a powerful xenon flash lamp from the bench. He directed the beam through the facepiece, and a circle of the material immediately turned dark. They could see through the area around the circle that the level of illumination inside the helmet had not changed appreciably. He moved the lamp around and the dark circle followed it across the visor.
'Built-in antiglare,' Gray observed.
'The visor is fabricated from a self-polarizing crystal,' Danchekker informed them. 'It responds directly to incident light in a fashion that is linear up to high intensities. The visor is also effective with gamma radiation.'
