Addressing the Origin of Life Narrative: James Tour on Chemistry, Stephen Meyer on ID at Cambridge

A pair of Cambridge lectures examining the deepest challenges in origin-of-life research—from the chemistry of early Earth to the information systems inside every cell—and exploring why current prebiotic models fall short. Featuring Dr. James Tour and Dr. Stephen Meyer, this session highlights the scientific roadblocks, the role of information, and the implications for how life began.
