Dr. James Tour argues that popular biology textbooks overstate how much science has explained life’s origin, while Rebekah presses him to explain why common origin-of-life claims sound stronger than the chemistry supports. The conversation centers on his critique of textbook language around early Earth chemistry, RNA world scenarios, protocells, and self-replication.
