Jo's special guest in episode 259 is Professor Adam Hart, who is professor of science communication at the University of Gloucestershire. Adam returns to do a new edition of myth busting, and he and Jo tackle the topic of extinction, as well as the issues around the idea of de-extinction.

Jo also visits the Grant Museum of Zoology at UCL to learn more about one extinct species - the dodo.
