The Origin of Life
The early Earth’s chemical ingredients, energy gradients, membranes, and catalysts—and the settings in which nonliving chemistry could begin to acquire life’s capabilities.
Full chapter 3 · 1 hr 41 min
The Origin of Life
The complete third chapter follows the chemistry of the early Earth through RNA, the genetic code, and the common ancestry of cellular life.

RNA Before Cells
RNA copying, chemical cycles, metabolism, and dividing compartments illuminate possible routes toward the first cells, along with the gaps experiments have yet to close.
The Genetic Code
How cells translate genetic information into proteins, why RNA sits at the heart of the ribosome, and what today’s shared genetic code reveals about its origins.
The Ancestor of All Cells
What the shared machinery of living cells reveals about LUCA, the last universal common ancestral population, and the deep split between bacteria and archaea.

How this film was made
Created and editorially directed by Anders Lunde using a custom production system developed over six months. AI assists research, drafting, programming, and visual production; I review and edit the material and make the final editorial decisions. Narration uses text-to-speech. Visuals combine custom-built scientific animations, AI-generated reconstructions, and credited scientific imagery.
Generated reconstructions illustrate scientific interpretations. They are distinct from photographs, specimens, and measured data.
