INTERLUDE ONE

The chapter speaks from an abstract, planetary perspective, asserting that life begins in darkness. In the deep ocean near volcanic vents, heat and rich chemicals catalyze simple chemistry into self-sustaining, insensate life, which accumulates into reefs and chimneys that channel heat and elements, enabling greater complexity.

Over immense timescales, colonies give rise to multi-part, immobile forms that sift the warmed waters for nutrients and the “snow” of dead life. Because vents are transient, mobile creatures emerge, slowly following chemistry and storing energy to survive movement between resource patches.

Predation develops as organisms find greater returns by consuming those already enriched by the vents. Ingesting concentrated toxins and metals forces adaptation: organisms excrete poisons as external shells and plates. What begins as waste becomes defense and then structure—a framework for limbs, claws, and tools fit for survival in the dark.

As respiration and exhalations accumulate, life gradually changes the ocean and, by extension, the atmosphere above. These environmental shifts create new niches at the margins, culminating in a pivotal transition: life, once bound to the vents and depths, crawls indolently onto the shore, inaugurating a new age of the world.
