Paul Nelson: … unless I misunderstand (always a live possibility), we’re back to postulating a “freak environment,” meaning the OOL explanation is a one-off event after all.

New origin of life thesis: Last Universal Common Ancestor (LUCA) wasn’t actually a single cell
Marshall favors horizontal gene transfer as a key method of early development because ancestor–descendant evolution is a “very slow” (42:25) evolutionary process. HGT among multiple independent lineages, by contrast, allows a “vast exchange of information,” thus sharing innovations and leading to faster development. Okay. And in the midst of all that, Dawkins’s Selfish Gene got lost in a crowd somewhere and was never heard from again.
