From Mitochondria to Minds: The Illustrated Science of the Psychedelic Dream Called Life

Like consciousness, like music, like love, life itself didn’t have to exist — nothing in the fundamental laws demands it. The universe could have gone on lapping at itself as a horizonless sea of pure spacetime, black and lifeless as the inside of a skull. But, in a whisper that soon became a symphony, life arose to give us such ceaseless wonders as the ghost pipe and the ginkgo, the bowerbird and the eye of the scallop. Neuroscientist Brian Isett and artist Claudia Biçen celebrate the wonder of how we went from mitochondria to minds in The Silent Teachers: How Nature Wrote the Story of Life (public library) — a love letter to that place between knowledge and mystery, where science illuminates the spirituality of nature. Beginning the story where nature began it, Isett writes in the opening chapter, “Ocean”: Once upon a time, Ocean taught life how to begin. The lesson began somewhere warm, like the shallow waters of a calm bay, or the billowing broth of a hydrothermal vent. In these places, warm water provided enough energy to link up chemicals that normally stayed apart. Rings of carbon, called “nucleotides,” clumped together just the way letters do to make words. And while most of the clumps formed nonsensical tangles, some formed babbling threads of an early genetic text called “RNA.” With Ocean’s encouragement, a chain reaction began: instead of dissolving back into the sea, chemicals began to fold into delicate structures that enabled even more chemical reactions to take place. These early molecules, many now called “ribozymes,” are thought to have sustained the first whispers of life. Our story had begun. The story unfolds like an Eames powers-of-ten shot, moving up the orders of complexity until the first grainy pixels begin to form a recognizable picture of the living world — the first cells, inside which “our earliest ancestors drafted and composed”; the skeleton, the lung, the fin that became a foot; and, along the way, the emergence of photosynthesis and fungi, of symbionts and sleep. Carrying the wonder of it all are Biçen’s vibrant illustrations, part fairy tale and part psychedelic dream. Pulsating beneath it all is an insistence that it is not too late to change the catastrophic course of ecology, that it can only be done by listening closely and creatively to nature’s own silent lessons, intimating that our mightiest instrument of resilience is rapturous wonder.
