We’re back and we’ve got some questions. When Jurassic Park roared into cinemas in 1993, it wasn’t just the dinosaurs that captured our imaginations – it was the idea that science might one day bring the prehistoric creatures back to life. Three decades and seven blockbusters later, the science of resurrection is edging closer to reality. Could we really bring back the dinosaurs?

This week, Emma Kennedy talks to Professor Andrew Pask, a geneticist at the University of Melbourne, about his mission to revive the Tasmanian tiger – and why recreating truly prehistoric species remains a scientific riddle.

WHY? is presented by Emma Kennedy. Produced by Liam Tait and Kathleen Johnson. Edited by Dominic Delargy. Theme music by Jade Bailey. Managing editor: Jacob Jarvis. Group editor: Andrew Harrison. Artwork by James Parrett. Additional music is from Artlist.io. WHY? is a Podmasters Production.
