Children of Time Summary: A Look at Evolution’s Unexpected Path
Children of Time follows two parallel lines: a terraformed planet where a virus accelerates the evolution of jumping spiders, and a decaying human ark ship searching for a new home.
The book spans thousands of years and shifts between the biological development of a spider civilization and the social decay of the last humans.

TL;DR: The Core Snapshot
A scientist seeds a planet with a virus meant to uplift monkeys.
The monkeys die in an act of sabotage, and the virus infects jumping spiders instead.
Thousands of years later, a human ark ship returns to the planet. The spiders have built a complex, biologically based civilization.
Conflict follows, but the spiders end the war by using a modified virus to force humans to feel empathy for them.
Key elements include:
- A failed human terraforming experiment on Kern’s World.
- The accidental evolution of sentient spiders with genetic memory.
- A decaying human ark ship, the Gilgamesh, ruled by competing factions.
- A final conflict resolved through biological empathy rather than extermination.

Doctor Avrana Kern oversees the Exaltation Program on a terraformed planet. Her goal is to seed the planet with monkeys and an uplift nanovirus to create a new sentient race for humanity.
A saboteur from the Non Ultra Natura movement destroys the facility. The monkeys die, and Kern survives only by entering a sentry pod.
Her consciousness partially merges with the pod’s computer system. The virus canister survives and falls to the planet below.
Without monkeys to infect, the virus targets native jumping spiders, Portia labiata. Over generations, the spiders grow larger and develop inherited memories they call Understandings.
Spider society advances through recurring figures named Portia, Bianca, and Fabian. They domesticate aphids and ant colonies, using chemical signals to turn the ants into living computers.
Eventually, the spiders build radios, optics, and orbital structures. They worship Kern’s satellite as a god called the Messenger.
Meanwhile, humanity survives aboard the ark ship Gilgamesh. The ship is a deteriorating vessel carrying half a million people in stasis. A Key Crew is awakened in cycles to manage crises.
The Gilgamesh reaches Kern’s World searching for refuge. Kern, still obsessed with her lost monkeys, drives the humans away as unauthorized biohazards.
The humans attempt to settle on a moon colony. The colony fails. A later expedition to a fungal terraforming world also ends in disaster.
Commander Vrie Guyen becomes obsessed with digital immortality. He builds a messianic cult among the ship-born humans and attempts to upload his mind into the Gilgamesh’s computers.
Chief Engineer Isa Lain and historian Holsten Mason oppose him. A civil war breaks out, and Guyen is killed. A corrupted version of his consciousness remains in the ship’s systems.
By the time the Gilgamesh returns to Kern’s World for a final attempt, the ship is dying. The spiders have achieved space travel and built an orbital web around the planet.
Kern finally accepts the spiders as her true heirs. She warns them about the approaching human threat.
The human crew launches a biological assault. Their goal is to wipe out the spiders. The spiders respond by boarding the Gilgamesh.
Instead of genocide, the spiders deploy a modified version of the uplift virus. The virus rewires the human brain to feel empathy and kinship toward spiders.
The war ends. Humans and spiders begin living together on the planet. The book closes with the launch of the Voyager, a joint starship crewed by both species.
