Evolution is a collection of short stories that work together to form an episodic science fiction novel. It follows 565 million years of human evolution, from shrewlike mammals 65 million years in the past to the ultimate fate of humanity (and its descendants, both biological and non-biological) 500 million years in the future.The primary protagonist in Evolution is evolution itself (although primates as a group constitute another protagonist). The book follows the hero's course as it shapes surviving pre-humans into tree dwellers, remoulds a group that drifts from Africa to a (then much closer) New World on a raft formed out of debris, and confronting others with a terrible dead end as ice clamps down on Antarctica.The stream of DNA runs on elsewhere, where ape-like creatures in North Africa are forced out of their diminishing forests to come across grasslands where their distant descendants will later run joyously. At one point, hominids become sapient, and go on to develop technology, including a universal constructor machine that goes to Mars and multiplies, and in an act of global ecophagy consumes Mars by converting the planet into its descendants. Human extinction (or the extinction of human culture) also occurs in the book, as well as the end of planet Earth and the rebirth of life on another planet. (The extinction-level event that causes the human extinction is, indirectly, an eruption of the volcano Rabaul, coupled with various actions of humans themselves, some of which are only vaguely referred to, but implied to be a form of genetic engineering which removed the ability to reproduce with non-engineered humans.) Also to be found in Evolution are ponderous Romans, sapient dinosaurs, the last of the wild Neanderthals, a primate who witnesses the extinction of the dinosaurs, symbiotic primate-tree relationships, mole people, and primates who live on a Mars-like Earth.
To Sandra, again. And to the rest of us, in hope of long perspectives
Judging from the past, we may safely infer that not one living species will transmit its unaltered likeness to a distant futurity. And of the species now living very few will transmit progeny of any kind to a far distant futurity.
As the plane descended toward Darwin it ran into a cloud of billowing black smoke. The windows suddenly darkened, blocking out the Australasian summer light, and the engines whined.
Joan had been talking quietly to Alyce Sigurdardottir. But now she shifted in her seat, the belt uncomfortably tight across her bulge. This was a roomy, civilized airplane, with even the economy seats set in blocks of four or six around little tables, quite unlike the cattle truck conditions Joan remembered from a childhood spent traveling around the world with her paleontologist mother. In the year 2031, a time of troubles, not so many people traveled, and those who did were granted a little more comfort.
Suddenly, as danger brushed by, she was aware of where she was, the people around her.
Joan watched the girl sitting opposite Alyce and herself. The girl, aged around fourteen at a guess, with a silvery gadget stuck in her ear, had been viewing tabletop images of the toiling Mars lander. Even here, ten thousand meters above the Timor Sea, she was connected to the electronic web that united half the planet’s population, immersed in noise and shining, dancing images. Her hair was pale blue — aquamarine, perhaps. And her eyes were bright orange red, the color of the Martian dust that filled up the smart tabletop. Doubtless she featured many other genetic "improvements" less visible, Joan thought sourly. Cocooned in her own expanded consciousness the girl had not even registered the presence of the two middle-aged women sitting opposite her — nothing save for a slight widening of the eyes at Joan’s figure when she had sat down, a reaction which Joan could read like a book:
But as the plane labored through the cluttered sky, the girl had turned to gaze out of the obscured window, distracted from her high-technology bubble, and the flawless skin of her brow was slightly furrowed. The girl looked scared — as well she might, Joan thought; all her genriched perfection wouldn’t help her a bit if this plane fell out of the sky. Joan felt an odd touch of meanness, envy wholly inappropriate in a woman of thirty-four. Be an adult, Joan. Everybody needs human contact, genriched or not. Isn’t that the whole point of your conference, that human contact is going to save us all?
Joan leaned forward and reached out her hand. "Are you all right, dear?"
The girl flashed a smile, showing teeth so white they all but glowed. "I’m fine. It’s just, you know, the smoke." Her accent was nasal U.S. West Coast.
"Forest fires," Alyce Sigurdardottir said, her leathery face creased into a smile. The primatologist was a slender woman of about sixty, but she looked older than that, her face deeply lined. "That’s all it is. The seasonal fires in Indonesia, and the Australian east coast; they last for months now, every year."
"Oh," the girl said, not really reassured. "I thought it might be Rabaul."
Joan said, "You know about that?"
"Everybody knows about it," the girl said, a hint of
"You’re well informed," Alyce said.
"I like to know what I’m flying into."
Joan nodded, suppressing a smile. "Very wise. But Rabaul hasn’t suffered a major eruption in more than a thousand years. It would be a little unlucky if it were to come just when you happen to be within a few hundred kilometers, uh—"
"I’m Bex. Bex Scott."
Bex — for Rebecca? —
Bex nodded, but Joan could see that under her bluster she wasn’t reassured.
