I am trying to understand the current work on abiogenesis in biology, e.g. primordial soup, the Miller-Urey experiment, etc.
How has our understanding of abiogenesis been revised since the Miller-Urey 'primordial soup' hypothesis?
Our understanding of how life began on earth has indeed advanced substantially since Haldane, Oparin, Miller, and Urey. To learn about the latest ideas, I can't think of a better place to start than this excellent video series with Nobel Laureate Jack Szostack, who is currently doing some of the leading work on the subject.
