"And finally," her expression had turned somber, "we get a relatively small number of results where all early testing suggests the trait we're trying to bring out is present. It's in there, waiting. But there's an instability factor, as well."
"Instability?" It had been Herlander's turn to ask the question when Fabre paused this time, and the geneticist had nodded heavily.
"We lose them," she'd said simply. The Simões must have looked perplexed, because she'd grimaced again . . . less happily than before.
"They do fine for the first three or four T-years," she'd said. "But then, somewhere in the fifth year, we start to lose them to something like an extreme version of the condition which used to be called autism."
This time it had been obvious neither of the younger people sitting on the other side of her desk had a clue what she was talking about, because she'd smiled with a certain bitterness.
"I'm not surprised you didn't recognize the term, since it's been a while since we've had to worry about it, but autism was a condition which affected the ability to interact socially. It was eliminated from the Beowulf population long before we left for Mesa, and we really don't have a great deal in even the professional literature about it, anymore, far less in our more general information bases. For that matter, we're not at all sure what we're looking at here is what would have been defined as autism back in the dark ages. For one thing, according to the literature we do have—which is extremely limited, since most of it's over eight hundred years old—autism usually began to manifest by the time a child was three, and this is occurring substantially later. Onset also seems to be much more sudden and abrupt than anything we've been able to find in the literature. But autism was marked by impaired social interaction and communication and by restricted and repetitive behavior, and that's definitely what we're seeing here.
"In this case, however, we think there are some significant differences, as well—that we're not talking about the same condition, but rather one which has certain gross parallels. It seems from the literature that, like many conditions, autism manifested in several different ways and in different degrees of severity. By comparison with what our reasearch has turned up about autism, what we're observing in these children would appear to fall at the extremely severe end of the spectrum. One point of similarity with extreme autism is that, unlike its milder form and other learning disorders, new communication skills don't simply stop developing; they're lost. These children regress. They lose communication skills they already had, they lose the ability to focus on their environment or interact with it, and they retreat into a sort of shutdown condition. In the more extreme cases, they become almost totally uncommunicative and nonresponsive within a couple of T-years."
She'd paused again, then shrugged.
"We think we're making progress, but to be honest, there's an element on the Board which thinks we should simply go ahead and abandon the project completely. Those of us who disagree with that position have been looking for a potential means of breaking the existing paradigm. We've come to the conclusion—or, at least, some of us have—that what's really needed here is a two-pronged approach. We've very carefully analyzed the genetic structure of all of the children in the entire line and, as I say, we think we've made substantial progress in correcting the genes themselves, the blueprint for the hardware, if you will. But we're also of the opinion that we're probably dealing with environmental elements that affect the operating software, as well. Which is what brings you to my office today.
"All our evaluations confirm that the two of you are a well-adjusted, balanced couple. Your basic personalities complement one another well, and you're clearly well-suited to one another and to creating a stable home environment. Both of you also have the sort of affinity for mathematics we're trying to produce in this line, if not on the level we're looking for. Both of you have very successfully applied that ability in your daily work, and both of you have demonstrated high levels of empathy. What we'd like to do—what we intend to do—is to place one of our clones with you to be raised by you. Our hope is that by placing this child with someone who has the same abilities, who can provide the guidance—and the understanding—someone intended to be a prodigy requires, we'll be able to . . . ease it through whatever critical process is going off the rails when we lose them. As I say, we've made significant improvements at the genetic level; now we need to provide the most beneficial, supportive, and nurturing environment we can, as well."
And that was how Francesca had entered the Simões' life. She didn't look a thing like either of her parents, although that was scarcely unheard of on Mesa. Herlander had sandy hair, hazel eyes, and what he thought of as reasonably attractive features, but he wasn't especially handsome, by any means. One thing the Mesan Alignment had very carefully eschewed was the sort of "cookie cutter" physical similarity which was so much a part of the Scrags descended from the genetic "super soldiers" of Old Earth's Final War. Physical attractiveness was part of almost any alpha or beta line, but physical diversity was also emphasized as part of a very conscious effort to avoid producing a readily identifiable appearance, and Harriet had black hair and sapphire blue eyes. She was also (in Herlander's obviously unbiased opinion) a lot more attractive than he was.
They were very much of a height, right at one hundred and eighty centimeters, despite the dissimilarity in their coloring, but it was obvious Francesca would always be small and petite. Herlander doubted that she was ever going to be much over a hundred and fifty-five centimeters, and she had brown hair, brown eyes, and an olive complexion quite different from either of her parents.
All of which only made her an even more fascinating creature, as far as Simões was concerned. He understood that fathers were genetically hardwired to dote on girl children, of course. That was the way the species was designed, and the LRPB hadn't seen any reason to change that particular trait. Despite that, however, he was firmly convinced that any unbiased observer would have been forced to admit that his daughter was the smartest, most charming, and most beautiful little girl who had ever existed. It was self-evident. And, as he'd pointed out to Harriet on more than one occasion, the fact that they'd made no direct genetic contribution to her existence obviously meant he was a disinterested and unbiased observer.
Somehow, Harriet had not been impressed by his logic.
He knew both of them had approached the prospect of parenthood, especially under the circumstances, with more than a little trepidation. He'd expected it to be hard to risk letting himself care for the girl, knowing as much as they'd been told about the problems the Board had encountered with this particular genome. He'd discovered, however, that he'd failed to reckon with the sheer beauty of a child—his child, however she'd become that—and the complete and total trust she'd extended to her parents. The first time she'd had one of the childhood fevers not even a Mesan star line was totally immune to, and she'd stopped her fretful crying and melted absolutely limply in his arms when he'd piecked her up, nestled down against him, and dropped into sleep at last, he'd become her slave, and he knew it.
They'd both been aware of the fact that they were supposed to be providing the love and nurture to help ease Francesca through the development process, as Fabre had put it. They'd been prepared to do just that; what they hadn't been prepared for was how inevitable Francesca herself had made it all. Her fourth and fifth years had been particularly tense and trying for them as she entered what Fabre had warned them was the greatest danger period, based on previous experience. But Francesca had breezed past the critical threshold, and they'd felt themselves relaxing steadily for the last couple of years.
