Do cells have goals? | with Melanie Challenger, Nick Lane & Philip Ball

A panel discussion held on the publication day of a new book titled Alive, featuring Nick Lane and Philip Ball, argues that mainstream biology's gene-centered account of life is incomplete. The panel traces the history of thinking about life from Aristotle's holistic psyche through Descartes' mechanistic body and 19th-century vitalism to the rise of DNA-centered biology, then tests that history against modern evidence, including synthetic spud cells that replicate but aren't alive and NASA's own definition of life, both of which the panel finds inadequate. They build a case that agency is a real, measurable property of organisms rather than a circular metaphor, grounding it in the physics of cellular energy production, in hydrothermal vent hypotheses where metabolism preceded genes, and in the single evolutionary event that produced eukaryotic and multicellular life. The discussion matters because it challenges the idea of genes as life's sole agents and bears on how we understand consciousness, brain organoids, and the real agency of AI systems.

• [03:08] The panel opens by challenging Richard Dawkins' 1991 claim that nature has no purpose and human purpose is just a brain-based byproduct of evolution
• [09:12] Synthetic biologists built 'spud cells,' lipid-membrane structures with a fully synthetic 36-gene genome plus hand-assembled enzymes and ribosomes (Adamala and Engelhart, University of Minnesota, 2026)
• [10:42] Spud cells can replicate, divide, and show selection-like competition, but aren't considered alive since they depend entirely on external chemicals, can't build their own ribosomes, and stall after a few rounds
• [23:06] Francois Jacob (1970) and Ernst Mayr (2004) framed biology around DNA and the genetic program as life's center, underpinning the Human Genome Project
