The Ganymeans had already interfered enough.
Chapter Twenty-Three
In Danchekker #146;s office, high in the main building of the Westwood Biological Institute on the outskirts of Houston, the professor and Hunt were watching the view of the
'It #146;s just coasting,' Hunt commented from an armchair set over to one side of the room. 'Seems as if they want to get one last look at us.' Danchekker said nothing but just nodded absently as he watched from behind his desk. The commentary coming over on audio confirmed Hunt #146;s observation.
'Radar indicates that the ship is still traveling quite slowly compared to the performance that we have seen before. It doesn #146;t seem to be going into orbit . . . just continuing to move steadily away from Earth. This is the last time you #146;ll have a chance to see this fantastic vessel live, so make the most of the moment. We are looking at the closing page of what has surely been the most astounding chapter ever written in the history of the human race. How can things ever be the same again?' A short pause. 'Hello, something #146;s happening I #146;m told. . . The ship #146;s starting to accelerate now. It #146;s really streaking away from us now, building up speed faster all the time. . . .' The image on the screen began to perform a crazy dance of growing and shrinking again at a bewildering rate.
'They #146;re on main drive,' Hunt said, as the commentator continued.
'The image is starting to break up. . . . The stressfield #146;s becoming noticeable now. . . . It #146;s going. . . getting fainter . . . That #146;s it. Well I guess that just about #151;' The voice and picture died together as Danchekker flipped a switch behind his desk to cut off the display.
'So, there they go to meet whatever destiny awaits them,' he said. 'I wish them well.' A short silence ensued while Hunt fished in his pockets for his lighter and cigarette case. As he leaned back in his chair again he said, 'You know, Chris, when you think about it, these last couple of years have been pretty remarkable.'
'To say the least.'
'Charlie, the Lunarians, the ship at Pithead, the Ganymeans and now this.' He gestured toward the blank screen. 'What better time could we have picked to be alive? It makes every other period of history seem a bit dull, doesn #146;t it?'
'It does indeed . . . very dull indeed.' Danchekker seemed to be answering automatically, as if part of his mind were still hurtling out into space with the
'It #146;s a bit of a pity, though, in some ways,' Hunt said after a while.
'What is?'
'The Ganymeans. We never really got to the bottom of some of the interesting questions, did we? It #146;s a pity they couldn #146;t have stayed around just a little longer #151;until we #146;d managed to figure out a few more of the answers. Actually I #146;m a bit surprised they didn #146;t. At one stage they seemed even more curious about some things than we were.'
Danchekker seemed to turn the proposition over in his mind for a long time. Then he looked up and across to where Hunt was sitting and eyed him in a strange way. When he spoke his voice was curiously challenging.
'Oh really? Answers to questions such as what, might I ask?' Hunt frowned at him for a second, then shrugged as he exhaled a stream of smoke.
'You know what questions. What happened on Minerva after the
'Oh, those.' Danchekker #146;s air of studied nonchalance was masterly. 'I think I can supply you with whatever answers you require to those questions.' The matter-of-factness in Danchekker #146;s voice left Hunt at a loss for words. The professor cocked his head to one side and regarded him quizzically but could not contain a slight admission of the amusement that he felt.
'Well. . . Good God, what are they then?' Hunt managed at last. He realized that in his astonishment he had let his cigarette slip from his fingers and made hasty efforts to retrieve it from the side of his chair.
Danchekker watched the pantomime in silence, then replied. 'Let me see now, to answer directly the questions that you have just asked would not really convey very much, since they all interrelate. Most of them follow from the work I have been doing here ever since we got back from Ganymede, which covers quite a lot of ground. Perhaps it would be simpler if I just start at the beginning and follow it through from there.' Hunt waited while Danchekker leaned back and interlaced his fingers in front of his chin and contemplated the far wall to collect his thoughts.
At last Danchekker resumed. 'Do you recall the piece of research from Utrecht that you brought to my attention soon after we got back #151;concerning the way in which animals manufacture small amounts of toxins and contaminants to exercise their defensive systems?'
'The self-immunization process. Yes, I remember. ZORAC picked that one up. Animals possess it but human beings don #146;t. What about it?'
'I found the subject rather intriguing and spent some time after our discussion following it up, which included holding some very long and detailed conversations with a Professor Tatham from Cambridge, an old friend of mine who specializes in that kind of thing. In particular, I wanted to know more about the genetic codes that are responsible for this self-immunization mechanism forming in the developing embryo. It seemed to me that if we were going to try to pinpoint the causes for this radical difference between us and the beasts, this was the level at which we should look for it.'
'And. . .'
'And, the results were extremely interesting . . . in fact, remarkable.' Danchekker #146;s voice fell almost to a whisper that seemed to accentuate every syllable. 'As ZORAC discovered, in virtually all of today #146;s terrestrial animals, the genetic coding that determines their self-immunization mechanism is closely related to the coding responsible for another process; you might say that both processes are subsets of the same program. The other process regulates carbon-dioxide absorption and rejection.'
'I see . . .' Hunt nodded slowly. He didn #146;t yet see exactly where Danchekker was leading, but he was beginning to sense something important.
'You #146;re always telling me you don #146;t like coincidences,' Danchekker went on. 'I don #146;t either. There was far too much of a coincidence about this, so Tatham and I started delving a bit deeper. When we investigated the experiments performed at Pithead and on board
Hunt considered the question for a few seconds.
'You mean that in today #146;s animals both processes are there, but all scrambled up together, but in the Oligocene species they #146;re separated out.'
'Yes.'
'
'Precisely, Vic.
'That doesn #146;t really make sense. I mean, the first thing you #146;d think would be that some kind of mutation had occurred to change one form into the other #151;the scrambled-up form and the separated-out form. That could have happened either way around. In one case the scrambled form could be the #145;natural #146; terrestrial pattern that became mutated on Minerva; that would explain why the animals from there have it and the descendants of the ones that were left here don #146;t. Alternatively, you could suppose that twenty-five million years ago the separated-out form was standard, which explains of course why the animals from that time exhibit it, but that in subsequent evolution here on Earth it changed itself into the scrambled form.' He looked across at
