While we're on a brief hiatus, we wanted to take a trip back in time to revisit our Season 2 premier from February 2019.

In this episode, Devon and Richard attempt to settle an age old argument between them by enlisting the help of renowned biochemist, professor, and author, Dr Nick Lane of the University College of London.

The debate: is there complex alien life somewhere out there, or is it improbable that there is anything more than cellular life. We look to the improbable origins of complex life on earth in search of answers.
