Adam Walton takes a leap into deep time, exploring the history of life on Earth...

Joining Adam is Palaeontologist and Evolutionary Biologist, Dr Thomas Halliday, to discuss his best-selling book ‘Otherlands: A World in the Making’.

Described as an exhilarating journey, 'Otherlands' takes us to eras that are unimaginably distant, examining the Earth as it used to exist at the dawn of complex life.
