Watchers

Walt said, “They’d name a warfare-related project after a saint?’
    “It’s apt,” Lem assured him. “Saint Francis could talk to birds and animals. And at Banodyne, Dr. Davis Weatherby was in charge of a project aimed at making human-animal communication possible.”
    “Learning the language of porpoises—that sort of thing?”
    “No. The idea was to apply the very latest knowledge in genetic engineering to the creation of animals with a much higher order of intelligence, animals capable of nearly human-level thought, animals with whom we might be able to Communicate.”
    Walt stared at him in openmouthed disbelief.
    Lem said, “There’ve been several scientific teams working on very different experiments under the umbrella label of the Francis Project, all of which have
    been funded for at least five years. For one thing, there were Davis Weatherby’s dogs . .
    Dr. Weatherby had been working with the sperm and ova of golden retrievers, which he had chosen because the dogs had been bred with ever greater refinement for more than a hundred years. For one thing, this refinement meant that, in the purest of the breed, all diseases and afflictions of an inheritable nature had been pretty much excised from the animal’s genetic code, which insured Weatherby of healthy and bright subjects for his experiments. Then, if the experimental pups were born with abnormalities of any kind, Weatherby could more easily distinguish those mutations of a natural type from those that were an unintended side effect of his own sly tampering with the animal’s genetic heritage, and he would be able to learn from his own mistakes.
    Over the years, seeking solely to increase the intelligence of the breed without causing a change in its physical appearance, Davis Weatherby had fertilized hundreds of genetically altered retriever ova in vitro, then had transferred the fertile eggs to the wombs of bitches who served as surrogate mothers. The bitches carried the test-tube pups to full term, and Weatherby studied these young dogs for indications of increased intelligence.
    “There were a hell of a lot of failures,” Lem said. “Grotesque physical mutations that had to be destroyed. Stillborn pups. Pups that looked normal but were less intelligent than usual. Weatherby was doing cross-species engineering, after all, so you can figure that some pretty horrible possibilities were realized.”
    Walt stared at the windshield, now entirely opaqued. Then he frowned at Lem. “Cross-species? What do you mean?”
    “Well, you see, he was isolating those genetic determinants of intelligence in species that were brighter than the retriever—”
    “Like apes? They’d be brighter than dogs, wouldn’t they?”
    “Yeah. Apes. . . and human beings.”
    “Jesus,” Walt said.
    Lem adjusted a dashboard vent to direct the flow of tepid air into his face. “Weatherby was inserting that foreign genetic material into the retriever’s genetic code, simultaneously editing out the dog’s own genes that limited its intelligence to that of a dog.”
    Walt rebelled. “That’s not possible! This genetic material, as you call it, surely it can’t be passed from one species to another.”
    “It happens in nature all the time,” Lem said. “Genetic material is transferred from one species to another, and the carrier is usually a virus. Let’s say a virus thrives in rhesus monkeys. While in the monkey, it acquires genetic material from the monkey’s cells. These acquired monkey genes become a part of the virus itself. Later, upon infecting a human host, that virus has the capability of leaving the monkey’s genetic material in its human host. Consider the AIDS virus, for instance. It’s believed AIDS was a disease carried by certain monkeys and by human beings for decades, though neither species was susceptible to it; I mean, we were strictly carriers—we never got sick
    from what we carried. But then, somehow, something happened in monkeys, a negative genetic change that made them not only carriers but victims of the AIDS virus. Monkeys began to die of the disease. Then, when the virus passed to humans, it brought with it this new genetic material specifying susceptibility to AIDS, so before long human beings were also capable of contracting the disease. That’s how it works in nature. It’s done even more efficiently in the lab.”
    As creeping condensation fogged the side windows, Walt said, “So Weatherby really succeeded in
