Can we bring animals back from extinction?

This panel brings together scientists from across the world to discuss the topic of de-extinction and how far the field of genetics has grown.
From dinosaurs to dodos, woolly mammoths to Tasmanian tigers, many species have become extinct with more likely to follow this path in the near future. Conservation efforts around the world are working hard to stop more species from joining this fate, but what about those that we have already lost? Has science progressed far enough that as well as preventing more from becoming extinct, we could bring these creatures back? Or perhaps more importantly, should we bring them back?
