About this episode

This episode explores the evolutionary question of echidna eggs and how AI can help address conspiracy theories.

This week on Lost in Science, Claire dives headfirst into the evolutionary echidna-and-egg conundrum: which came first — the placental mammal or the mammalian egg of our humble monotreme cousins? Then Stu explores fascinating new research into how artificial intelligence might help bring people back from conspiracy theories — not by arguing louder, but by engaging directly with the evidence that convinced them in the first place. Can AI help untangle deeply held beliefs?
